What Makes Microcement Waterproof?
Microcement itself is not naturally waterproof—but when combined with the right membrane, base coats, and sealing system, it becomes a fully water-resistant surface.
Conmarble’s microcement waterproof system includes:
Waterproofing membrane (essential for showers & wet rooms)
High-adhesion primers
Reinforced microcement base layers
Finish coats designed for wet areas
Two-component polyurethane or acrylic topcoat
This system transforms microcement into a continuous waterproof shell with zero joints, zero grout lines, and zero weak points.
Tiles fail at the joints.Microcement eliminates joints entirely.
Why Architects Choose Microcement Over Tiles in Wet Areas
1. Seamless, Joint-Free Waterproofing
With no grout, no tile lines, and no cracks—water has nowhere to enter.
Perfect for:
Showers
Spa zones
Hotel bathrooms
Wellness centers
Luxury suites
Kitchens & splash walls
The seamless look isn’t just aesthetic—it’s functional durability.
2. Resistant to Mold & Humidity
Because the surface has no joints, mold cannot grow in gaps or porous cement lines.
Microcement’s sealed surface:
Repels water
Prevents bacteria buildup
Is easy to clean
Stays beautiful for years
This makes it ideal for high-end hotels and villas where maintenance must be minimal.
3. Waterproof on Any Surface

Tiles
Concrete
Marble
Plasterboard (moisture-resistant)
