Microcement bathrooms

Seamless bathrooms and showers, specified as a complete sealed system - waterproofing included, not implied.

What to expect

A bathroom is where seamlessness earns its keep. Grout lines are where wet rooms fail visually first and hygienically second, and a microcement bathroom has none - the floor runs into the upstand, up the wall and around the niche as one surface.

The honest version of the waterproofing story is this: microcement is not waterproof on its own. In a wet area it is specified as a system, with the substrate waterproofed beneath it, the correct primer, the body coats and a sealer chosen for continuous water contact. Falls, drainage and tanking still have to be right underneath it.

The sealer is a maintenance item, not a permanent state. Re-sealing intervals depend on the product and the use, and they belong in the handover documentation rather than in a sales sentence.

In practice

Floor, upstand, wall and niche in one continuous surface with no grout lines Applied over correctly waterproofed and tanked substrates, with falls set beneath Specified for showers, hammams and spa treatment areas as a complete system Can go over existing tile where the substrate is sound, avoiding a strip-out Re-sealing intervals confirmed at handover and recorded in the maintenance schedule

Specify it

System Waterproofing, primer, body coats and a sealer rated for continuous water contact
Waterproofing Tanking and falls are a substrate responsibility, completed and tested first
Applied thickness Approximately 2 to 3 mm depending on floor or wall
Sealer A maintenance item - re-application interval set by product and use
Not suitable Over substrates with unresolved movement, damp or failed tanking

Microcement is a durable, low-VOC cement-based finish. It is not a natural or vapour-open material — for that, see clay plaster or lime plaster. Emission and content testing is published by the manufacturer.
