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

Aquapanel

Want to use this product on Aquapanel, is that ok? Do I need to use the primer? Also will the use of this product impact the tile weight limit that the board can handle? Thanks.
Asked by: T1mM
Mapei Shower Waterproofing Kit can be used with cement based tile backer boards, such as Aquapanel, without the need to apply the enclosed primer within the kit, provided that the board is thoroughly clean and dust free before application. The maximum weight tolerance of the backer board will not be reduced due to the application of the Mapei Shower Waterproofing Kit.

Can this be used over painted and plastered walls?

One wall is plastered which has been painted over with a 'splashproof' bathroom type emulsion. Other wall is new Aquapanel. Do I need to remove the 'splashproof' emulsion before using this kit? OK for Aquapanel?
Asked by: Remodeller
Before installing the Mapei Shower Waterproofing Kit the substrate must be solid, clean, dry and free of oils, grease, old paintwork or any other materials which could compromise bonding. Mapei Shower Waterproofing Kit is suitable to be used on cementitious tile backer board such as Aqua Panel.

Can this product be used on top of plywood that has been coated with PVA

Asked by: DIYHOME11
Unfortunately we would not advise using Mapei products over a PVA surface, in this instance we would recommend abrading the plywood until the substrate is clean and contamination free.

What is the recommended adhesive and white grout for sticking ceramic 20x20cm tiles, 6 square metres after having used this waterproofing kit on the walls?

Asked by: Tiz123
To bond 200x200mm ceramic tiles onto the Mapei Shower Waterproofing Kit we would advise the Mapei Buildfix Wall Tile Adhesive off White 15KG (5832C). Once the adhesive has fully cured grout the tiles using the Mapei Buildfix Flexible Wall & Floor Grout White 2.5KG (70239). Due to the characteristics of Mapei Buildfix Wall Tile Adhesive off White 15KG (5832C) onto the Mapei Shower Waterproofing Kit, it should be taken into consideration that the drying time will be increase.
