What it is

Microcement is a cement-and-resin coating that is hand-troweled over your existing floors, walls, or tile in thin layers — the complete PURO system is only about 2–3 mm thick. Because it bonds directly to what is already there, including old tile, you get one continuous, grout-free surface without demolition. It is not a paint and not a slab: it is a layered system — primer, cementitious base coat, two colored finish coats, and a clear protective sealer.

Why choose it

• Renovates over tile with no demolition — Primer BC bonds straight to ceramic, tile, glass, wood, and MDF, so the old surface stays in place and the tear-out, dumpster, and weeks of re-tiling never happen.
• Seamless and only about 2–3 mm thick — no grout lines to scrub, no height buildup that blocks doors or transitions, one continuous surface across floors, walls, and curbs.
• Shower-ready as an assembly — over code-compliant waterproofing, SuperTitanium BC (32 ± 2 MPa compressive strength at 28 days, EN 1015-11) plus the UV-stable, non-yellowing Atriapol antibacterial topcoat (ISO 22196:2011 certified) build a complete wet-area system; no single coat is the membrane — the assembled stack is what performs.

How it’s applied

1. 01Your surface gets the primer matched to what it is: Primerquarz for absorbent walls, or Atriafloor Primer BC on floors — bare concrete and screed as well as tile, ceramic, wood, and glass. The substrate has to be sound before priming: solid, dry, and vacuumed free of dust and loose material. A chalky or friable slab has to be made sound first — Primer BC is an anchoring primer, not a consolidant, and must not go over an unstable surface.
2. 02In showers and wet rooms, a code-compliant waterproofing layer goes down before anything else — the finished assembly built over it is what makes the room waterproof.
3. 03Rasante One, the cementitious base coat, is troweled on to level the surface, with fiberglass mesh embedded where reinforcement is needed.
4. 04Two thin coats of your chosen finish — Titanium, SuperTitanium BC, Titanium Superfino, or Resina One — build the color and the hand-troweled texture.
5. 05Two coats of Atriapol sealer, matte or gloss, lock the surface against wear and stains.
6. 06Light foot traffic is fine about 12–14 hours after the final sealer coat; treat it gently while it reaches full cure over 5–7 days.
