Product description

Seamless, fully waterproof microcement walls — without the mixing. Microforce RTU comes ready to use: open the tub, add the colour pigment and trowel it on. Choose the smooth, very fine Thin finish or the medium-grain Rustik finish, in 12 kg tubs.

Applied over RTU Base, it goes straight over existing tiles, making it a fast, clean way to renew showers and bathrooms.

Supplied by Microstone UK, Newcastle-under-Lyme. Contact us for stock and lead time.

How it's applied

Prepare — clean, sand and open the surface.
Prime — Hidroprimer on absorbent surfaces; Primer 2C with quartz on non-porous surfaces; Epoxim Plus 3C on damp substrates.
Level — over tiles or uneven walls, 1–2 coats of RTU Base. Floors always need two coats of Base plus mesh.
Finish — mix the pigment into the tub, low speed then high, until uniform. Apply with a flexible trowel, 3–4 hours between coats, sanding with 150 grit.
Seal — one coat of Acryseal with a sponge trowel.
Protect — after 2 hours, two coats of Aquamax (matt, satin or gloss), 12 hours apart. Fully sealed 24 hours after the final coat.

Not suitable for swimming pools or exterior use. Manufacturer data is indicative — always test on site.
