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

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 ?

Answer: 
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.

The wall is plasterboard and most of the old adhesive has been removed, exposing the plaster surface in places but some arears still have a thin layer of well spread old adhesive so the final surface is not completely smooth but flat enough to fix tiles.

Answer: 
Mapei Shower Waterproofing Kit can be used on existing substrates however the substrate must be solid, clean, dry and free of oils, grease, old paint work or any other material which could compromise bonding. Thoroughly clean all the mould, loose materials, etc. from existing surfaces which will be waterproofed.

If the damage to the plasterboard is extensive we would advise repairing the plasterboard with an appropriate product before install the Mapei Shower Waterproofing Kit.

Answer: 
For bonding tiles of this size to the Mapei Shower Waterproofing Kit tanking system we would recommend either Mapei Rapid-Set Adhesive Grey 20.0kg (29634) or Mapei Keraflex Tile Adhesive White 5kg (42841).

Answer: 
Unfortunately the Mapei Shower Waterproofing Kit only comes in one size. However as an alternative you can purchase Mapei Aquadefence Waterproofing Membrane 7.5kg (8531D) with Mapei Jointing Tape White/Grey 120mm x 5m (69510).

The coverage for Mapei Aquadefence Waterproofing Membrane 7.5kg is approx 1kg/m2.
