Polished Plaster Saudi Arabia – Luxury Microtadelakt Finishes for Refined Interiors
Polished plaster is emerging as a signature element in Saudi Arabia’s high-end interior design, bringing Old-World elegance into modern luxury homes and venues. It refers to lime-based plaster that is hand or machine burnished to create a smooth, marble-like surface with a natural sheen. In the Saudi climate and design context, polished plaster (especially Microtadelakt, a refined lime plaster system) offers not only aesthetic richness but also practical benefits like breathability and humidity regulation. The result is a seamless, artisanal finish that graces walls and ceilings of upscale villas, cultural landmarks, spas, and boutiques across the Kingdom. Designers and homeowners are drawn to its tactile depth, natural variegation, and the way it elevates interiors with a touch of Mediterranean and Moroccan charm – all while being perfectly suited to Saudi Arabia’s environment and Vision 2030 sustainability goals.

Historical Evolution of Polished Plaster
Polished plaster’s story spans millennia and continents – from ancient Morocco and Rome to Renaissance Italy and now modern Saudi Arabia. This finish is the product of techniques refined over centuries:
In Marrakech and Fes, artisans developed Tadelakt, a traditional lime plaster technique used to waterproof the walls of hammams, palaces, and even drinking-water cisterns. Applied in multiple coats, Tadelakt is hand-polished with a smooth stone and then black olive soap is rubbed into the surface. The olive oil soap chemically reacts with the lime, forming calcium stearate that seals the plaster and makes it waterproof. The result is a subtly mottled, silky surface revered for its spa-like elegance and durability. Tadelakt embodies the connection between craftsmanship and wellness architecture – its high pH even gives it anti-mold properties.
By the Renaissance, lime plaster techniques traveled to Europe. In Venice, Italy, they evolved into Venetian plaster (or Stucco Veneziano), made from slaked lime mixed with finely ground marble dust. Venetian plaster was typically applied in thin layers and burnished to a high-gloss finish that mimics polished marble. It gained fame in the palazzos of Venice for its mirror-like sheen and depth. A variant known as Marmorino emerged, offering a more matte or satin, stone-like texture with layered visual depth. These Italian finishes brought an artistic flourish to walls – from classic Baroque residences to today’s contemporary interiors – and proved that lime plaster could be both decorative and deeply luxurious.
Fast forward to the present, and polished plaster has been reimagined for modern needs. Microtadelakt is a high-performance lime plaster developed to honor those traditional techniques while enhancing their ease of use and durability. Pioneered in part by Spanish manufacturers (like Cemher) and adopted by specialists such as Conmarble, Microtadelakt retains the ancient soul of Tadelakt and Venetian plaster but requires no olive soap sealing and has additives (like marble powder and carefully controlled chemistry) that make it stronger and more versatile. It can achieve the same silky smooth, polished look or be left in a matte finish as desired. Today in Saudi Arabia, Microtadelakt polished plaster is bringing this heritage full circle – from the riads of Marrakech and halls of Venice to the calligraphy museums, hotels, and private estates of Riyadh and Jeddah, marrying tradition with innovation.
Throughout its evolution, polished plaster has remained a symbol of refined taste and craftsmanship. Whether it’s the glowing hammam walls of old Marrakech or a sleek feature wall in a Riyadh penthouse, this finish carries a legacy of luxury. Now, Saudi Arabia’s designers are writing the next chapter of that story, using polished plaster to infuse interiors with a sense of timelessness and cultural continuity.
Composition and Characteristics of Polished Plaster
Polished plaster is fundamentally a mineral composition, which is key to its beauty and performance. Traditional recipes and modern Microtadelakt formulations share similar core ingredients:
The primary binder of polished plaster is lime, obtained by firing limestone and then “slaking” it in water. This lime is what makes the plaster a “living surface” – as it cures on the wall, it reacts with carbon dioxide in the air to re-form into limestone (calcium carbonate). This process, called recarbonation, means the wall literally hardens to stone over time and even absorbs CO₂, purifying the air. Lime gives the plaster its breathability (porous open structure) and high alkalinity, which naturally resists mold and bacteria. Unlike cement, lime plaster also has a degree of flexibility, allowing it to self-heal micro-cracks by re-crystallizing over time.
Finely ground marble or limestone aggregate is mixed in to strengthen the plaster and contribute to its stone-like look. The marble powder gives polished plaster its weighty, mineral depth and subtle shimmer. When the plaster is compressed and polished, the marble content is what catches the light and can be buffed to a low sheen or even a gentle gloss. It essentially turns the wall into a thin veneer of marble, but one that is seamless and can coat complex shapes. Marble dust also increases the plaster’s hardness after full curing, making the surface durable and scratch-resistant.
Mineral oxide pigments can be added to the lime plaster to produce a wide range of colors. From earthy ochres and warm beiges to cool greys and off-whites, polished plasters are tinted through-and-through with pigments, so the color will not peel or flake like paint. The color tends to have a soft, variegated appearance due to the hand application – giving walls a rich, variegated tone. In Saudi Arabia, designers often favor neutral tones (sand, ivory, stone grey) that complement contemporary luxury decor, but virtually any color can be achieved, and custom color matching is possible.
Besides water (which hydrates the lime and helps in application), high-end modern polished plasters like Microtadelakt may include small amounts of additives like pozzolans or polymers (in minimal quantity) to improve adhesion and workability, though Conmarble’s formulation prides itself on having no synthetic resins or VOCs. The lack of acrylic binders means the plaster remains fully breathable and natural. Some formulations are one-component mixes that just require water on site, simplifying installation without compromising purity.
Key characteristics emerge from this composition: Polished plaster finishes are breathable, hypoallergenic, and eco-friendly. They have thermal mass, meaning they can help keep interiors cooler by not trapping heat – a bonus in Saudi’s climate. They also regulate humidity by absorbing moisture when the air is humid and releasing it when dry, contributing to a healthier indoor environment. The surfaces are seamless and monolithic, unmarred by grout lines, which is both aesthetically pleasing and hygienic. Visually, the combination of lime and marble yields a unique depth: as light hits a polished plaster wall, it penetrates microscopically into the translucent lime and refracts off the marble particles, giving a sense of movement and softness that flat paint can’t match. Yet the finish is matte to satin by nature (unless waxed to high gloss), so it doesn’t produce harsh glare – instead, it exudes a gentle glow or *“natural shine”*.
In summary, polished plaster is essentially artisanal limestone coating your walls. It offers the permanence and luxury of stone alongside the handcrafted warmth of a plaster finish. These characteristics make it an ideal choice for those seeking a blend of beauty, performance, and authenticity in refined interiors.
Polished Plaster Finishing Techniques
Achieving the signature look of polished plaster is as much about how it’s finished as it is about the material itself. There are two primary polishing techniques – manual and mechanical – each yielding a slightly different aesthetic and suited to different project types. Conmarble’s artisans in Saudi Arabia are skilled in both the traditional hand troweling methods (often using Italian tools) and modern mechanical polishing with high-grade resin pads.
Manual Polishing of Polished Plaster
Manual polishing is the time-honored technique that connects directly to the traditions of Tadelakt and Venetian plaster. Here, the applicator uses special trowels and spatulas – typically flexible steel trowels with rounded edges (often called Italian spatulas or Venetian trowels) – to burnish the plaster by hand. After the final coat of plaster is applied and begins to set, the artisan sweeps the trowel over the surface with firm pressure at a precise angle, repeatedly. This compression action tightens the plaster’s pores and brings out a subtle sheen on the surface. Skilled applicators learn to use varying pressure and strokes to coax nuanced tonal variations (the plaster may darken slightly where more pressure is applied, giving cloud-like effects). The friction from the trowel even generates mild heat, which helps to further smooth and “close” the lime.
Key aspects of manual polishing include:
It requires a high level of craftsmanship to avoid trowel marks and achieve uniformity. The applicator must judge the right timing (plaster neither too wet nor fully dry) and have a steady, practiced hand. Done correctly, it produces walls that have a handcrafted character – a very soft glow and organic movement in the finish that many clients describe as “alive.” No two hand-polished walls are exactly alike, which is part of the appeal.
Common tools are the stainless steel Venetian trowel, Japanese flex trowel, or even a traditional stone for true Moroccan Tadelakt. Often, a smaller spatula tool is used for tight areas or final touch-ups. The term Italian spatula simply refers to these high-quality European tools that allow fine control. They must be kept very clean and often have rounded corners to prevent gouging the delicate plaster.
Manual polishing is often preferred for boutique projects, curved surfaces, and areas requiring artistic finesse. For example, in an intricately detailed majlis (traditional sitting room) or a boutique retail space like Afraa Boutique, hand polishing can highlight niches, arches and ornamental details with a bespoke touch. It’s also well-suited to smaller feature walls or residences where the goal is a one-of-a-kind artisanal appearance.
The result of manual polishing is a luminous satin finish that feels smooth as silk to the touch. One can often see the subtle trowel movement preserved in the sheen, which catches the light gently. This method is labor-intensive and almost a form of art – which is why polished plaster is valued as a luxury finish.
Mechanical Polishing of Polished Plaster
Mechanical polishing is a modern approach that uses power tools to achieve a higher and more uniform sheen on polished plaster, especially over large areas. After the plaster fully dries (or in some cases after it has set firm), installers use rotary or orbital polishing machines with resin-bonded diamond abrasive pads of progressively finer grit. This method can produce a mirror-like smoothness if desired, and is great for speeding up work on expansive surfaces.
Key features of mechanical polishing include:
The process typically involves sanding the plaster lightly with fine abrasive pads, starting around 400–800 grit and moving through extremely fine grits (1500, 3000 and up). For a true polished-stone effect, pads up to 4000-grit or even 6000-grit are used. At these high grits, the abrasives are so fine that they buff the plaster to a soft shine rather than visibly abrading it. Conmarble’s team often employs up to 6000-grit pads to achieve an extra depth of sheen on Microtadelakt finishes, replicating the look of honed marble. Each stage removes microscopic roughness from the surface, incrementally increasing reflectivity.
Using a machine allows for even pressure and coverage, which can be beneficial on large flat walls or long corridors where a consistent finish is desired across the entire area. It also can be quicker than exhaustive hand troweling – for example, burnishing thousands of square meters in a museum or hotel lobby by hand would be extremely time-consuming, whereas polishing machines can cover ground faster. Mechanical polishing thus makes polished plaster viable for big commercial projects without sacrificing quality.
While polishing, workers may mist the surface with a bit of water or use pads designed to stay cool, ensuring the lime doesn’t overheat or burn. Proper technique is needed to avoid swirl marks or uneven gloss. Generally, mechanical polishing is done only after the plaster has sufficiently cured to handle it (often a day or more after application).
This technique shines in hospitality and commercial environments – e.g. a high-end hotel lobby in Jeddah, an art gallery, or a large modern villa – where you have expansive walls or ceilings that need a uniform high-end finish. It’s also useful if a client specifically wants a higher gloss level than hand troweling typically provides. Mechanical polishing can achieve a near-marble satiny reflection when viewed at an angle, yet the surface still retains the depth of a plaster (it won’t look like a synthetic paint).
It’s worth noting that some projects use a combination: artisans might hand-trowel and partially burnish the final coat, then follow up with a mechanical polish once everything is dry to give it that last degree of smoothness. In both methods, the final appearance can also be adjusted by the optional application of wax or soap finishes (more on that in the next sections), but as far as the plaster itself is concerned, these polishing techniques are what yield the classic “polished plaster” look. Whether done by skilled hand or machine, the goal is the same – compressing the plaster to a lustrous finish that is visually and tactilely exquisite.
Benefits of Polished Plaster in Saudi Arabian Interiors
Polished plaster isn’t just chosen for its beauty – it offers a suite of benefits particularly well-suited to interiors in Saudi Arabia. Here are some key advantages of using Microtadelakt polished plaster in the Saudi context:
Polished plaster instantly elevates a space with an Old-World elegance that also suits contemporary styles. It has a depth, movement, and “soul” that flat wall finishes lack. The gentle marbling effect and soft reflection create an ambiance of understated luxury, whether in a private Riyadh villa or a high-end restaurant. Because it’s a handcrafted finish, it imparts exclusivity – no two polished plaster walls are identical, so your interior feels unique. This finish complements everything from modern minimalist decor to classic Arabian design motifs.
One huge aesthetic and hygienic benefit is that polished plaster is applied in a continuous coating. There are no tile grout lines, seams, or panel joints – just smooth expanses of plaster. This makes spaces like bathrooms, hallways, and feature walls look cleaner and more expansive. In Saudi Arabia’s luxury design, where open-plan spaces and large feature walls are common, this seamless quality is prized. It also means the finish can wrap around curved stairwells, domes, and archways fluidly, achieving architectural designs that would be impossible with cut stone or tile.
Traditional lime plasters had a reputation for longevity (many historic palaces still have original plaster), and modern Microtadelakt is engineered to be even tougher. It is reinforced with marble content and applied in thin layers that cure to stone-like hardness. Microtadelakt is formulated to be flexible and micro-crack resistant, meaning it can handle typical building movements or vibrations without spiderweb cracking. It also resists impacts fairly well – if struck, it tends to dent slightly rather than shatter, and such spots can often be repaired. In high-traffic interiors (hotels, office lobbies) or heavily used areas of the home, polished plaster holds up excellently over time, outlasting many paint jobs. Unlike paint, it won’t peel or flake since it is integral to the wall surface.
Polished lime plaster is an ideal finish for Saudi Arabia’s varied climate – from the humid Red Sea coast to the dry inland. Lime plaster regulates humidity naturally by breathing. It absorbs excess moisture when the air is humid (preventing condensation) and releases it when the air is dry, which helps maintain a comfortable indoor environment. This quality also prevents issues like mold or mildew; the plastered walls stay dry and alkaline, inhibiting microbial growth. Additionally, when properly polished and optionally sealed with wax, Microtadelakt becomes water-resistant enough for use in bathrooms and spa areas. Unlike gypsum or ordinary paint, it won’t deteriorate in damp conditions. This makes it superb for hammams, showers, and washrooms – a big benefit in luxury Saudi homes where spa-like bathrooms are popular.
In Saudi Arabia’s heat, polished plaster can contribute to cooler interiors. The plaster’s breathability and high thermal mass allow walls to “sweat” moisture and stay relatively cool to the touch, somewhat akin to the effect of traditional mud or stone walls. This can reduce reliance on air conditioning a bit and even out interior humidity swings. Moreover, because it doesn’t trap moisture, interior air quality is improved and the space feels fresher. Many wellness-focused designs (yoga studios, wellness centers in the Gulf) choose lime plaster for this reason.
Polished plaster is **100% natural and free of volatile organic compounds (VOCs)**. There are no chemical off-gassing or paint fumes – the indoor air remains healthy, which aligns with the wellness trends among high-end homeowners. Lime is antimicrobial, so it literally resists bacteria and keeps the walls hygienic. Importantly, as mentioned, lime plasters like Microtadelakt actually absorb CO₂ as they cure, effectively making them carbon-neutral or even carbon-negative finishes over their lifecycle. For clients or projects aiming for LEED certification or Saudi’s Vision 2030 sustainability targets, this is a major plus – the walls actively contribute to a lower carbon footprint. Conmarble’s plaster is aligned with these green building goals, using all-natural ingredients.
From a design perspective, the versatility of polished plaster is a benefit. It can be finished in different textures and sheens (matte, satin, polished) and can take on essentially any color. It suits ultra-modern interiors just as well as traditional ones. A single material can be used throughout a home – in the foyer, the living room, the powder bath, even the kitchen backsplash – creating a cohesive look that ties spaces together. It also plays nicely with other luxury materials: stone floors, wood paneling, metal accents, etc. Rather than competing, polished plaster’s subtlety often enhances those elements by providing a quiet, elegant backdrop.
In essence, polished plaster provides an upgrade over paint or wallpaper in every way for the luxury market: it’s more beautiful, more durable, healthier, and highly customizable. These benefits explain why it’s become a sought-after finish for refined Saudi interiors, from beachfront Jeddah villas to high-rise apartments in Riyadh.
Main Components of Polished Plaster and Their Roles
Understanding what goes into polished plaster helps clarify why it performs so well. Here are the main components of a Microtadelakt polished plaster and the role each plays:
As the base binding agent, lime (calcium hydroxide) is responsible for the plaster’s ability to harden and adhere to surfaces. After application, the lime slowly carbonates by reacting with CO₂, turning back into hard calcium carbonate (essentially limestone). This gives the plaster its strength and longevity – your walls gradually become stone. Lime also imparts the breathable pore structure, allowing moisture vapor to pass. Its alkalinity (high pH) creates an inhospitable environment for mold and bacteria, contributing to the plaster’s healthy indoor quality. Unlike cement, lime remains slightly flexible and can accommodate minor movements, preventing cracks.
Finely crushed marble or limestone powder is mixed into the plaster to act as an aggregate filler and to add hardness. Marble powder effectively densifies the plaster and gives it that distinctive weight and stone-like feel. Critically, it’s what enables the plaster to be polished – as the surface is compressed, the tiny marble particles help it develop a sheen and a subtle sparkle in light. The higher the marble content, generally the more polishable (Venetian plaster for example often has very high marble content for high gloss). In Microtadelakt, the marble content strikes a balance between sheen and strength. This ingredient also contributes to the plaster’s compressive strength and wear resistance once cured.
Natural oxide pigments (such as iron oxides for reds, yellows, and browns, or cobalt for blues, etc.) are added to achieve the desired color. These pigments are UV-stable and lime-fast, meaning they won’t degrade in the alkaline lime. They allow polished plaster to come in a wide range of colors without any paint layer – the color is integral to the plaster. Pigments must be blended thoroughly for uniform tone, or intentionally left varied for a mottled effect. They play no role in structure, but in design, they are crucial for matching the client’s palette. In Saudi Arabia, earthy neutrals and soft whites are popular, often achieved with blends of multiple pigments to mimic natural stone hues.
Water is the medium that activates lime and allows the plaster to be spread. As it evaporates during curing, the plaster hardens. Some modern mixes include additives like micro-fibers (to improve tensile strength and crack resistance) or small amounts of latex polymer (to aid adhesion on tricky substrates). However, Conmarble’s Microtadelakt focuses on a pure mineral recipe with no acrylic binders, preserving the authentic characteristics of lime. One additive that is naturally present is fine sand or pozzolan in some basecoats, to bulk out lower layers – but the finishing coats are usually just lime and marble for maximum smoothness.
Each of these components works in harmony when the plaster is applied. The lime binds to the wall and to the marble particles; the marble adds body and polish; the pigments add beauty; and the absence of synthetic materials means the plaster retains the natural advantages of its ingredients. The result is a wall finish that is essentially reconstituted limestone with decorative coloring, imbued with the artisan’s hand through the way these components are applied and finished.
Where Can Polished Plaster be Applied in Saudi Arabia?
One of polished plaster’s strengths is its versatility – it can be used almost anywhere a creative designer or homeowner can imagine, turning ordinary surfaces into eye-catching features. In Saudi Arabia, the following applications are common and ideal for Microtadelakt polished plaster:
Any representative space – be it the grand foyer of a Riyadh villa, the reception area of an office, or a living room accent wall – can be finished in polished plaster for a sophisticated, seamless look. The plaster’s subtle texture and sheen make even large flat walls interesting, catching sunlight and lamp light in a lively way. High-ceilinged majlis rooms, dining halls, and corridors in upscale homes benefit from the classic, smooth backdrop polished plaster provides, replacing the need for wall papers or cladding with something more permanent and bespoke.
In contemporary design, a single feature wall in polished plaster can become the focal point of a room – for example behind a bed in a master suite or at the end of a hallway. Similarly, dome ceilings or coved ceilings in villas can be finished with plaster and then polished to a soft glow, highlighting architectural form. Because Microtadelakt can be applied overhead and on curved surfaces, it’s perfect for special ceiling treatments (like in a luxury spa’s steam room or a boutique’s fitting room dome).
Polished plaster truly shines in wet areas where you want a seamless, water-resistant finish. In Saudi Arabia’s high-end homes and resorts, Moroccan-inspired hammams and modern spa bathrooms are popular – polished plaster provides the authentic material for those, without resorting to tiles. Walls in showers, vanity backsplashes, bathtub surrounds, and even built-in bench seats can be done in Microtadelakt, yielding a spa environment that is continuous and grout-free. It stands up well to moisture when sealed with wax, and its breathability helps prevent mold in these humid zones. Many luxury spas (hotel spas in Riyadh, for example) choose lime plaster finishes to create that calming, wellness-centric atmosphere.
Elegant public spaces like boutique stores, hotel lobbies, restaurants, and art galleries are increasingly using polished plaster for its high-end look. In a place like Afraa Boutique in Doha’s Place Vendôme Mall, for instance, Microtadelakt plaster was chosen to envelop the interior in a sense of soft luxury that complements couture fashion. Restaurants in Jeddah or Khobar might use a polished plaster feature wall to add warmth and craftsmanship to otherwise slick interiors. The material gives an artisanal touch that aligns with the bespoke image of luxury brands and hospitality venues. It’s also practical for such spaces because it’s hard-wearing and easy to clean.
Saudi Arabia has a rich architectural heritage, and when restoring or creating cultural sites (museums, galleries, cultural centers), polished lime plaster fits right in. It has been used in the Prince Mohammed Bin Salman Global Center for Arabic Calligraphy (Madinah) to magnificent effect, and it can be applied in mosques or heritage homes where a traditional yet refined finish is desired. Its roots in Islamic architectural tradition (through Tadelakt) make it culturally resonant. Designers can also incorporate patterns or calligraphy carvings into polished plaster before it sets, merging art with wall finish.
Beyond walls and ceilings, Microtadelakt can be applied to certain built-in furnishings and details – e.g., fireplace surrounds, molded columns, or even cabinetry facades – to unify them with the walls. In contemporary designs, we’ve seen plaster-finished console tables, headboards, and planter boxes to match the walls. While not common, it’s a possibility that expands creative use. The plaster’s seamless nature allows it to cover free-form shapes that would be hard to veneer otherwise.
In summary, polished plaster can coat almost any interior surface that is properly prepared, except floors (for which microcement is preferred) and very high-abrasion areas. Its use ranges from the most private spaces (bathrooms) to grand public interiors, proving its adaptability. In the Saudi Arabian design landscape, which values both innovation and a connection to heritage, polished plaster finds a welcome home in palaces old and new, in cutting-edge commercial designs and serene personal retreats alike.
Polished Plaster Finishes, Colors, and Textures
One of the most exciting aspects of polished plaster is the variety of finishes that can be achieved. Far from a one-note finish, it can be tailored in sheen, texture, and color to meet design visions. With Microtadelakt, Conmarble can deliver finishes ranging from rustic matte to high-gloss marble, as well as custom textures. Here’s an overview:
Polished plaster can be left matte, satin, or highly polished depending on technique and preference. A matte finish (achieved by minimal compression and no waxing) shows off the plaster’s natural color depth and tends to look more organic and stone-like; it’s great for a subtle, earthy ambiance. A satin finish (standard burnishing, maybe one coat of natural wax) yields a soft glow and is the most popular, balancing elegance with a relaxed feel. A glossy or mirror finish (achieved by intense hand burnishing or mechanical polishing + multiple wax coats) can make the wall look almost like polished marble or travertine. High gloss Venetian-style is less common in residential Saudi interiors but can be stunning in contemporary galleries or very opulent spaces. The key is that the sheen is adjustable continuously – a designer can work with the applicator to stop at the desired luster.
While polished plaster is often associated with smooth surfaces, artisans can create intentional textures for effect before polishing. For example, a pitted or dragged texture can be made (similar to Travertino style) where the plaster is applied with a coarse roller or sponge and partially polished, leaving a travertine stone appearance. A Marmorino texture can be done by applying in overlapping patches to create subtle clouds and movement; when polished, this gives the wall a tonal variation reminiscent of natural stone veining. There’s also the possibility of combining matte and burnished areas to produce depth – sometimes called a tone-on-tone effect. Tools like combs, spatulas, or even stencils can imprint patterns that are then polished over for a very bespoke finish. However, in most refined Saudi projects, the preference leans toward a consistent, smooth texture – either sleek or slightly suede-like – to exude that calm, monolithic luxury. The plaster can also be left with fine “movement” marks from the trowel for a classic Venetian look, or it can be polished until absolutely uniform.
Polished plaster’s color comes from its mix, so essentially any color can be made by blending pigments. Conmarble offers a curated palette of popular tones – often 20+ stock colors – ranging from warm beiges, desert sand, and off-whites to cool greys and charcoals. Soft muted colors tend to be favored for large areas, as they show off the plaster’s natural variation best. Bright or very dark colors are possible (for instance, deep blacks or rich terracotta reds), but they are used carefully as they can show burnish marks more. Custom color matching is a big advantage – if an owner wants the plaster to match a specific stone or textile, the artisan can adjust pigment proportions to achieve it. Over time, lime-based colors also develop a gentle patina – for example, a white plaster might warm slightly or a grey might deepen in richness, adding to the character.
For clients who want something truly unique, polished plaster can be augmented with special techniques: metallic waxes (adding a slight gold or pearlescent sheen in the final wax coat), integral aggregates (like tiny crushed mother-of-pearl or black stone pieces troweled into the finish – as was done in the Calligraphy Museum to reflect local heritage), or fresco work (painting designs onto a base plaster coat and then plastering over with a translucent layer). These are advanced options, but they highlight that polished plaster is as much an art as a finish. In retail, for example, a logo or motif can be subtly built into the plaster layers for branding.
In Saudi Arabia’s design market, the emphasis is often on neutral, elegant finishes – so you’ll frequently see polished plaster in ivory, sand, pale grey, or soft taupe, with a smooth texture and satin sheen, creating a canvas for furnishings and art. However, the material offers the flexibility to go bolder if desired. The finishes, colors, and textures can be customized “at every level” to fit the project’s narrative. This versatility is why polished plaster is considered a premium solution – it’s not off-the-shelf; it’s tailored to each interior, much like a bespoke suit.
Step-by-Step Polished Plaster Installation Process
Installing polished plaster is a meticulous, multi-step process that requires skill and patience. Below is a step-by-step overview of how Conmarble applies Microtadelakt polished plaster in practice. Each step is critical to achieving that flawless, durable finish:
Like any high-end finish, preparation is key. The substrate (wall or ceiling surface) must be clean, stable, and suitably rough. Typically, a base of cement render, blockwork, or moisture-resistant gypsum board is used. Any loose paint or debris is removed. If the wall is too smooth or non-absorptive, a primer or bonding agent is applied to ensure the plaster will grip. The team patches any cracks or holes and makes sure the surface is flat and plumb, because polished plaster goes on thin and will telegraph any imperfections. In Saudi Arabia, new construction often provides cementitious basecoats ready for plaster – these are ideal. On gypsum drywall, a scratch coat might be added for good measure. Proper masking of adjacent surfaces is done, since application can be messy.
If required, a base coat of lime plaster (or a prepared Microtadelakt base) is applied first. This coat is slightly coarser and thicker – perhaps 1 to 2 mm – to even out the surface and establish a groundwork. It might include fine sand for strength. The base coat is allowed to dry partially and is lightly troweled to even it. Its job is to cover the substrate fully and provide a uniform ground for subsequent coats. In some cases, especially on absorptive cement, the base coat can be skipped and one of the finish coats can act as base. Conmarble evaluates this on site.
The finish coats are where the beauty comes. Microtadelakt is applied in typically 2 to 4 ultra-thin layers. Each coat is very thin – on the order of 0.5 mm or less (practically as thin as a playing card). An applicator uses a trowel to spread the plaster in broad or random strokes, depending on the desired texture. After each coat is applied, it’s left to partial set – not fully dry; this may be anywhere from 30 minutes to a few hours depending on conditions. Before it hardens completely, the artisan goes over it with the trowel (or a plastic float) to compress it slightly (this is pre-burnishing). This compression helps each layer adhere well and eliminates air pockets. Subsequent coats are applied on top of previous ones once the previous is firm enough to take pressure but still a bit damp – this ensures a good bond between layers (wet-on-damp application yields a monolithic result). The choice of 2, 3, or 4 coats depends on the desired finish effect: more coats can give more depth and movement in color; fewer coats may appear more uniform. By the final coat, the plaster has built up to only ~2mm total thickness, yet it is fully opaque and covering.
The last coat is the most important for appearance. It’s applied very thinly and as smoothly as possible. Once it loses its surface wetness and starts to firm up, the applicator begins the hand-polishing (burnishing) process with a clean steel trowel or spatula. They work in sections, using curved strokes and consistent pressure to rub down the plaster. You can actually hear a slight scraping/squeaking sound when it’s at the right point – that’s the sound of the trowel fine-tuning the plaster. This compaction closes the lime’s pores, which is what ultimately yields a more water-resistant and smooth surface. The wall is often polished multiple times: initially while it’s just setting, and again a bit later when it’s drier, to perfect the sheen. If a very glossy finish is desired, this is also when a stone or high-grit abrasive pad might be used gently to further buff the surface. By the end of this step, the plaster has its final shape and texture – a smooth, continuous wall with the chosen level of polish.
If the spec calls for a higher sheen or if the area is large, the team may next do a mechanical polish once the plaster is fully dry (usually the next day). Using a power polisher with fine pads, they buff the entire surface, going through finer grits to even out the sheen. This step can remove any remaining micro-roughness and enhance reflectivity. It’s especially useful for very large walls where hand-polishing might have slight variations. The mechanical polish is done cautiously to avoid burning the surface. This step is often skipped in smaller residential jobs if the hand finish is already excellent, but it’s a common step for expansive commercial walls.
After polishing, and once the plaster has fully dried, Conmarble typically applies a protective wax sealer called Cera. Cera is a plant-based natural wax (often a beeswax or carnauba-based product) that is buffed into the surface of the plaster. This is done with a soft cloth or buffer in a thin layer. The wax serves a few purposes: it enhances water repellency (important for bathrooms or kitchens) by adding a hydrophobic layer, it adds a soft satin sheen (or even high gloss if multiple coats are applied and buffed), and it protects the surface from stains. The key is that the wax used is breathable – it doesn’t clog the plaster’s pores entirely, thus preserving some of the breathability. After application, the wax is left to haze and then buffed off, similar to waxing a car, leaving a gentle luster. (In historical Tadelakt, olive soap plays a similar role; here, modern wax makes it easier and longer-lasting.)
At this point, the polished plaster looks complete, but it’s not at full strength yet. Over the next 2–4 weeks, the lime will continue to carbonate (cure), getting harder and harder. During this time it will also deepen slightly in color and sheen as it fully dries and reacts. The crew instructs that the surface should be protected from harsh use during this period – though it’s generally usable within 1–2 days for light activities. They remove all masking and do a thorough cleanup of the area. Any faint trowel marks or pigment blooms that are noticed can be touched up by lightly buffing that spot or re-waxing. By the end of the curing period, the wall reaches its final hardness and beauty.
Every step in this process is vital: skipping proper prep or rushing drying times can result in adhesion issues or uneven finish. That’s why polished plaster is truly a job for trained artisans – it’s a marriage of science and craft, requiring knowledge of materials (how lime behaves) and a high level of workmanship. Conmarble’s team in Saudi Arabia follows this step-by-step method, honed through experience, to ensure that the finished product – whether in a small powder room or a vast museum hall – is flawless and enduring. The result of this careful process is a wall finish that can last for decades, aging gracefully and often improving in character over time as it fully becomes part of the building’s fabric.
Polished plaster refers to a lime-based wall finish that is troweled smooth and then burnished to create a marble-like sheen. It’s made of slaked lime, marble dust, and pigments – essentially a type of refined plaster that can be polished until it’s glossy. At Conmarble, this is achieved using their Microtadelakt lime plaster applied in thin coats, then polished either by hand or machine, and usually sealed with a natural wax for protection. The result is a seamless, breathable, and luxurious surface that has depth and movement, often used in high-end interiors across Saudi Arabia. Polished plaster is sometimes called Venetian plaster or Marmorino in other parts of the world, but in our context it specifically highlights the glossy, artisanal lime plaster finish.
In Conmarble’s context, yes – Microtadelakt is the proprietary lime plaster mixture we use to create polished plaster finishes. Think of Microtadelakt as the material, and “polished plaster” as the finish or result. When we apply Microtadelakt and polish it to a shine, you get the polished plaster look. The base material (Microtadelakt) can also be left unpolished for a matte look, but once we polish and wax it, it becomes that classic polished plaster. So polished plaster is essentially a high-finish version of Microtadelakt. The difference from plain Microtadelakt is mostly in the technique – multiple polishing passes and the waxing that give it that satiny, reflective character.
They are closely related and often the terms get mixed up. Both are lime-and-marble plasters that are polished to look like stone. The differences come down to formulation and traditional usage:
-
Venetian plaster is a broader term originally referring to the Italian technique (Stucco Veneziano). It often has a higher marble content and is associated with a high-gloss, mirror finish that you might see in Renaissance Italian palaces. Venetian plaster techniques sometimes involve multiple colors and a lot of hand burnishing to achieve a very deep gloss and variegation.
-
Polished plaster (as we use the term with Microtadelakt) can achieve a range from matte to gloss. It tends to be used in a more contemporary or natural aesthetic context – we often go for a soft sheen (satin) that feels more organic, suiting modern Middle Eastern interiors. Microtadelakt also is formulated to be a bit more forgiving and flexible than some Venetian plasters, which means less risk of cracking and it’s breathable and VOC-free. In short, Venetian plaster is one style of polished plaster (very glossy and usually Italian-origin), whereas Conmarble’s polished plaster is Venetian-inspired but adapted to be more versatile and sustainable. We offer that Venetian look if a client wants, but with our materials that have no synthetic additives and better moisture tolerance.

When properly finished and sealed, polished plaster is water-resistant, which covers most needs like bathrooms or backsplashes. By itself, polished Microtadelakt lime plaster has tight pores from burnishing and is hydrophobic to a good degree. We enhance this by sealing with Cera wax, which makes the surface repel water. Thus, polished plaster is perfectly suitable for areas with splashing water: showers, bathroom walls, powder rooms, spa zones – all are fine and we have done many of these. You’ll see water bead on the surface rather than soak in. However, it’s not recommended for continuous immersion (like inside a swimming pool or fountain). For submerged applications, other systems would be used (e.g., microcement or specialty pool plasters). So, “waterproof” in the sense of daily usage – yes, with wax it functions much like tiles (minus grout). Just wipe up standing water occasionally and re-wax every few years to maintain performance.
Yes, polished plaster can work nicely in kitchens (for example, on a backsplash or as a wall finish) with some considerations. Because it’s sealed and stain-resistant, cooking splashes can be wiped off easily and it won’t soak up oils if cleaned promptly. It’s actually easier to keep clean than a textured tile grout. We do recommend avoiding direct high-heat areas – for instance, right behind a gas range where flame could contact the wall – as lime plaster could discolor under extreme heat. But for general wall areas in a kitchen or a bathroom vanity area, it’s great. In a kitchen, one should plan to re-wax periodically (perhaps every 2-3 years) because constant cleaning and exposure to various substances might wear the wax faster. The wax will keep it protected from wine or juice stains, etc. And of course, maintain good ventilation (which you’d do anyway) so that any moisture evaporates. In summary, it’s viable for kitchens, but treat it like a natural stone backsplash in terms of care (no abrasive scrubbing, re-seal occasionally).
When applied correctly over a stable substrate, polished plaster is highly crack-resistant. Microtadelakt has additives and a fine fiber matrix that make it more flexible than old traditional plasters. It’s applied in thin layers which also minimizes stress. Normal building settling or minor movements usually do not result in visible cracks. In fact, lime plaster can handle small movements by micro-cracking at a scale that is nearly invisible, and the appearance often can self-heal or be burnished if needed. It also doesn’t flame or peel like paint might – since it’s a single monolithic layer, you won’t see sections delaminating unless the base underneath moves significantly. That said, large structural cracks in the wall itself can of course transmit through (no wall finish is immune to that), but those are repairable as mentioned earlier. As for chipping: it takes a fairly strong impact with a sharp object to chip it – more than what typical wear causes. For instance, scraping it hard with a metal furniture edge might leave a mark, but gentle bumps won’t. In day-to-day use, polished plaster holds up well and edges (if plastering corners) are usually protected or rounded to avoid chipping. Many historical lime plasters have lasted centuries; while Microtadelakt hasn’t existed that long, it’s engineered to be long-lasting.
The timeline depends on the area size and complexity, but generally polished plaster is a multi-day process. For example, for a standard room or accent wall (let’s say 100–150 square meters of surface), Conmarble’s crew might take 3 to 5 days from start to finish. Day 1 could be surface prep and base coat, Days 2–3 for successive finish coats, and Day 4 for final polishing and waxing. If mechanical polishing or extra drying time is needed, add a bit more. We often allow an extra day as a buffer to ensure quality. Larger projects scale up with more crew rather than dramatically longer time – e.g., 1000 m² in a lobby might take a couple of weeks with a team of artisans working in sections. It’s worth noting the plaster itself needs about a month to fully cure hard, but this doesn’t mean you can’t use the space – light use can resume a day or two after completion. We just advise care during that curing period. Compared to paint, it’s a longer process, but for a luxury finish it’s quite efficient. We coordinate with project schedules to break the work into phases if needed. Ultimately, the time invested in applying polished plaster is paid back by the fact that you won’t need to re-do those walls for many, many years.
FAQ
How to Maintain Polished Plaster Surfaces
One of the pleasant surprises about polished plaster is that it is relatively easy to maintain, especially considering its luxury status. With minimal care, polished plaster surfaces will look beautiful for years. Here are guidelines and tips on maintenance:
Day-to-day cleaning of polished plaster is simple. Dust the surface occasionally with a soft, dry cloth or feather duster to remove any accumulated dust. For more thorough cleaning, use a damp (not soaking wet) sponge or microfiber cloth and gently wipe the surface. If needed, you can use a pH-neutral mild soap (like a gentle dish soap or a specialty stone soap) diluted in water to remove fingerprints or grime. Avoid any aggressive scrubbing – usually a light wipe is enough since the plaster doesn’t trap dirt easily. Thanks to the wax finish (if applied), many spills will bead on the surface, giving you time to wipe them before they can cause any staining. Always avoid acidic cleaners or vinegar, as acids can etch lime-based plaster, and do not use abrasive pads that could scratch the burnished surface. Also, do not apply generic wall cleaning agents or sealants that are not recommended for lime plaster – these could film over the breathable surface.
In wet areas (showers, etc.), ensure that the area is well-ventilated so the plaster can dry out after use. Polished plaster can handle occasional water contact (especially with wax), but it’s still wise to wipe down shower walls after use to prevent soap scum buildup. Never use bleach or harsh bathroom cleaners on it – a neutral soap works fine for any cleaning needed. If mold ever does appear (rare, and usually only if ventilation is poor), it should be cleaned with a very mild alkaline cleaner – but the plaster’s high pH generally prevents mold growth in the first place.
Over time (measured in years), the protective wax layer may slowly wear down, especially in high-use areas like showers or backsplashes. A good rule of thumb is to reapply the natural wax (Cera) every 3–5 years in such areas. This will refresh the plaster’s water repellency and sheen. Re-waxing is straightforward: the new wax is buffed on and off just like when first installed. Homeowners can often do small areas themselves with the right product, or they might have Conmarble come in for a professional touch-up. In drier areas (bedrooms, hallways), re-waxing may not be needed for a decade or more, or at all. The plaster itself is still sound; the wax just enriches the surface protection. When re-waxed, the wall often regains its just-installed glow, and any tiny wear marks disappear as the sheen evens out.
Should the plaster get a nick or scratch, it can typically be repaired by a skilled applicator without redoing the whole wall. Minor scratches can sometimes be buffed out with a damp sponge and gentle pressure, reactivating the lime a bit and then re-polishing that spot. For deeper gouges or chips, an artisan can fill the spot with a matching plaster mix, then sand and polish to blend it in. Because of the variegated nature of the finish, small repairs tend to blend invisibly once re-polished. This is a big advantage over something like paint, where a patched area often shows. It’s worth noting that lime plaster surfaces actually self-heal aesthetically to an extent – tiny cracks that might appear in very new plaster can be burnished down or simply become part of the patina and are hard to notice. If the building structure causes a larger crack, that section can be reworked by cutting out and reapplying plaster, then blending it. Professional maintenance services are available for such cases, though they are uncommon if the plaster was applied well on a stable substrate.
Polished plaster is often said to improve with age. Over months and years, the lime continues to harden (fully curing in about a month, but micro-improvements happen beyond that). As it does, the surface might develop an even softer sheen and the color can become a touch richer or more varied, enhancing that natural look. This gentle evolution is usually desirable – it’s akin to a fine leather developing a patina. In the dry climate of Riyadh or AlUla, the aging effect can be even more pronounced – walls gain a slight “eggshell” glow that is hard to replicate with any synthetic finish. There’s no need to repaint or refresh polished plaster every few years as with paint; it’s built to last decades. If tastes change, it can be painted over or skimmed with a new plaster, but most homeowners keep it as-is and let it age.
By following these simple maintenance steps – gentle cleaning, occasional re-waxing, and timely touch-ups if needed – polished plaster surfaces will remain as stunning as the day they were finished. Many owners find that maintenance is actually less effort than painted walls (which scuff and attract dirt more easily). Plus, knowing that the material is natural and breathable gives peace of mind; you’re not dealing with peeling layers or chemical cleaners. In essence, treat polished plaster like you would treat a piece of fine furniture or natural stone – with care and respect for its natural qualities – and it will reward you with lasting beauty. With minimal care, your Microtadelakt walls in Saudi Arabia will continue to enrich your space over time, developing character while maintaining their luxurious appeal.
