Is the sealer really waterproof?

Yes. Two coats of the 2K polyurethane sealer make the microcement fully waterproof at the surface — the specification used for showers, wet rooms and (in its pool-grade variant) swimming pools.

How long before I can walk on it?

Light foot traffic at 24 hours ; full cure for heavy traffic and water exposure at 7 days .

Can I use it outdoors?

Yes — the UV-stable variant keeps colour stable on outdoor terraces and pool decks and prevents chalking under sun exposure.

The waterproof sealer that finishes the microcement system

The PU Sealer & Varnish is what turns a beautiful microcement surface into a durable, waterproof, stain-resistant floor or wall. It is specified across the KCBerry range — Microtraffic, Micronoslip, Microfinishing and Poolciment — with matt and satin options depending on the finish specified.

For wet zones it delivers the R11 anti-slip performance of Micronoslip; for outdoor terraces it is UV-stable so colour does not chalk under Irish daylight.

Two thin coats, then live with it

Roll on the first coat, wait 4 hours, roll the second. Light foot traffic at 24 hours, full cure at 7 days for heavy traffic and water exposure. The result is a jointless microcement surface that cleans with a damp mop and no grout to worry about.
