About this finish
Primers & Sealers
What it is
Which of these do I actually need? This family is the invisible half of every ATRIA system: the primer that makes the finish stick, and the sealer that makes it last. The rule is simple — Primerquarz for walls, Atriafloor Primer BC for floors, whether that is bare concrete and screed or existing tile, wood, and glass — and every floor or wet-area job ends with Atriapol on top, because microcement is never waterproof from a single can: it is the sealed assembly, base coat plus Atriapol, that handles water.
Atriafloor Primer BC: The difficult-surface primer. A two-component water-based epoxy that anchors to ceramic, tile, stoneware, wood, MDF, and glass — the product that lets microcement go over existing tile without demolition.
Why choose it
- Two primers cover every substrate — quartz-grip acrylic for walls, and an anchoring two-component epoxy that bonds to concrete, screed, tile, wood, and glass — so renovation rarely means demolition.
- Both Atriapol topcoats carry ISO 22196:2011 antibacterial certification (tested against E. coli and S. aureus) and are UV-resistant and non-yellowing.
- The topcoat spec is measured, not promised: over 10,000 wet-abrasion cycles (DIN 53778) and adhesion above 3.6 MPa (EN 1542) — measured on the topcoat that finishes the waterproof-by-assembly system.
How it’s applied
- 01Match the primer to the surface: Primerquarz on walls, Atriafloor Primer BC on floors — bare concrete, screed, tile, ceramic, wood, MDF, or glass.
- 02Prepare the substrate first: it must be solid, dry and clean. Completely remove dust, residues, and loose or flaking parts by vacuuming, brushing, or sanding — Primer BC must not go onto a dusty or unstable surface. It anchors to a sound substrate; it does not consolidate a weak or friable one, so a chalky slab needs making good before you prime.
- 03Roll or brush on one coat and let it set — Primerquarz recoats in 4–6 hours; the epoxy Primer BC waits overnight, 8–12 hours minimum.
- 04Apply your decorative coat — Titanium, SuperTitanium, or Resina One — over the primed surface. On floors, the Atriafloor One Rasante base coat goes between primer and resin.
- 05Finish with 2–3 coats of Atriapol, matte or gloss — this sealed assembly, not any single product, is what makes bathrooms and showers work.
- 06Floors take foot traffic after about 12–14 hours; deep dry follows at 18–24 hours.
Where it works
Before you commit to a prep stack, order the made-to-order sample board of the finish you are planning — $15 ($25 for Metallicum), with $15 credited toward any order of $100 or more — so you can judge the sealed final surface in your own light. Order a sample board
