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
Specify it
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.

Technical support for the design team
We supply the material and we apply it, so the specification and the workmanship sit with one party. Send a finishes schedule, an elevation or a mood board and we will come back with the system, the build-up, the sample programme and a completed clause.
