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

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.

Answer: 
For bonding ceramic tiles no larger than 300x300mm we would recommend using Mapei Buildfix Wall Tile Adhesive Off White 15kg (Product code 5832C). However due to the non porous nature of the waterproofed background the drying time of the adhesive may be extended.
