Hi - wondered if anyone could advise, please?
Builder installed wet room; the floor is wedi and the shower cubicle is wedi on the floor and the walls.
Outside the shower cubicle, about 18" where the tiles stop by the door into the wet room, the plaster is showing some damp above the skirting board. I don't understand where this has come from - the builder is blaming the sand and cement grout, and claiming that re-grouting (e.g. BAL) will stop this re-occurring.
The floor is tiled with slate tiles, wide spaced and sand and cement grout between. The walls are tiled with ceramic tiles.
Surely, if the floor is wedi, there should be no path for damp to the plaster? even if the floor tiles are damp by osmosis from the shower area?
I am concerned that the wedi tape is not deep enough to allow for the slate tiles, so that the damp tiles are in contact with the walls above the tape - is that possible?
Also, should the upstand in the wedi drain be sealed to the drain, or left open to allow free draining from the wedi layer?
Many thanks! H.
