Why microcement works in bathrooms

Microcement can go on floors, walls, shower enclosures and worktops, and over plaster, cement, tiles or timber. The result is one seamless surface with no grout lines for dirt, mould or mildew to collect in.

The choice of system matters more here than anywhere else. Water exposure is constant, so the finish has to resist water through its whole build, not just at the surface.

Our pick for bathrooms: ErreLAB

For showers, wet rooms and busy family bathrooms, we recommend ErreLAB’s resin systems: Spatolato, Velato, Pietra Continua and Metallo Continuo. They resist water at every layer, so even if a sealer is scratched, water can’t soak in behind it.

Each one carries on from the floor up the walls and into the shower with no joints, and they’re extremely hard wearing and stain resistant. The one exception is ErreFast, ErreLAB’s quick acrylic finish: it isn’t suitable for showers and other wet areas, but like Politura it works elsewhere in the bathroom, away from direct water.

Applying it in a bathroom

Resin goes on the same way as mineral microcement, built up in thin layers. The main difference is mixing: ErreLAB products are usually two or three components. Over tiles, carbon fibre or mesh goes into the base coat, and wet areas may need a moisture-barrier primer.

Our ErreLAB training course covers preparation, application and sealing.

How long it takes

Politura or ErreFast2–3 days, for floors, walls and worktops away from direct water.

ErreLAB4–5 days, built up in layers so every coat resists water.

Before the first showerSealers need time to cure. Ask us for the timings for your system.

Looking after it

Wipe down showersA quick squeegee or wipe after use stops limescale building up.

Gentle cleaners onlyAvoid abrasive pads and harsh chemicals. Soap-based cleaners can leave a slippery film on floors.

LimescaleIf it builds up, ask us which cleaner suits your system.

Ask for the care guideWe’ll send the maintenance guide for your system.
