Rated 4 out of 5 by from Good Thanks for help and good services I wanted to build shower with waterproof on the floor and wall this will be used by guests.

Rated 5 out of 5 by from Quick and easy to apply An excellent product that could save you many times it's cost by avoiding water ingress into plasterboard backing. Much easier than replacing plaster board with cement based backer boards. However if starting from scratch I'd always consider lining around showers with cement based boards.

Rated 5 out of 5 by from Tanking ensuite shower Good stuff. This did exactly what it was designed for - waterproofing the shower before tiling. At first I thought it was really expensive but seeing the results I thought the expense was justified. I would recommend this ...

Rated 5 out of 5 by from Very good waterproofing kit Bought this kit recently for waterproofing my new shower. Applied to two adjacent walls and the ply floor. Two applications are enough to form a layer. Since the tiles will cover the waterproofing layer, it is easy to apply using a brush than a roller to create some rough textures on the surface to provide more grips. I would recommend this for any new shower

Can This be used on Mapei MAPEI ULTRAPLAN SELF-LEVELLING COMPOUND

I will be tanking my wetroom and also using the self level compound on the floor. Can the tanking kit be applied to the self leveling compound? Also should I tank then self level. Or self level then tank?
Asked by: Jimcorny1
Mapei Shower Waterproofing Kits can be used over all Mapei self levelling compounds. Mapei Shower Waterproofing Kit should be applied to the finished substrates prior to the intended tiled finish being bonded, in this case the waterproofing would be applied to the surface of the levelling compound.

Is it possible to retank under just one tile in a corner?

When a single tile is removed and adhesive is chipped off the wall, will the tanking get damaged ? If so can I just reapply tanking and a small piece of corner tape behind the removed corner tile before applying the new tile ?
Asked by: Dotsanddots
When removing tiles from waterproof membranes there is always a possibility of damaging the membrane its self. Reapplying the membrane would be best practice, although as the system will no longer be a continuous coat we would not be able to guarantee one hundred per cent that moisture will not penetrate thorough. However the possibility of this happening with the repaired section will be minimal.
