Rated 5 out of 5 by 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. 5 Sep 2016
Rated 5 out of 5 by 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 ... 29 Aug 2016
Rated 5 out of 5 by 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 4 May 2016
Rated 5 out of 5 by Overbath tanking Used this to tank the walls over my bath before fitting an electric shower. Really easy to follow instructions and will hopefully last for years and years. Great product. 1 Mar 2016

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: 
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.

Answer: 
Mapei Shower Waterproofing Kit can be used in conjunction with most Mapei adhesive stocked by Screwfix. Depending on the substrate your tiling and the type of tile we would suggest the following:

Mapei Buildfix Wall Tile Adhesive off white (5832C) - This is a ceramic wall tile adhesive which can bond to the Mapei Shower waterproofing kit as long as the tiles are porous and no greater than 300 x 300mm.

Mapei Keraflex Tile Adhesive White 5kg (42841) - This adhesive can be used on wall and floor application adhering small to medium format ceramic and porcelain tiles to the Mapei Shower Waterproofing Kit.
