Rated 5 out of 5 by from It Works So I looked in the other shops and 5Kg of the same type of product was twice the price. I bought this and it did the job perfectly. I put three coats and put tiles on top. Perfectly happy and will buy it again

Rated 3 out of 5 by from Not for every situation It probably is a good product for flooring and worktop tiling situations but for wall tiling I would not use again. It does not bond to every substrate and for the substrates it does bond to I don't need water proofing.

Rated 5 out of 5 by from This stuff is great Went on nice, good dry colour change so seeing the second coat was easy. cannot really comment on performance yet, or reliability but it looks good 3 days after application, really finishes the room...!

How long can I leave this on the wall before tiling it? A few days? Week?

Asked by: R1867
When tiling you want to bond the tiles as soon as possible as dust is your enemy, if the area is left untiled for longer than 12-24 hours after application ensure that the surface is clean and dust free before applying the selected tiles.

Can this be painted over a painted surface on a wall and will it need a key on the wall before tiling?

Asked by: R1867
we would recommend that the paint be removed from the surface so that the Mapei Aquadefense bonds directly to the substrate and not to the paint that is potentially surface contamination.

Does the tub cover 7.5m2 over the 2 coats?

Asked by: R1867
The consumption rate is 1kg/m2 for 2 coats. So you stated the 7.5kg unit will cover approx. 7.5m2

Outside wood on conservatory roof.

Can this paint be used to protect and seal an old wooden conservatory that has started leaking. I will be using a sealant on the joints. this would just be for the wood panels that are starting to rot. Many Thanks
Asked by: Angie276
Unfortunately Mapei AquaDefense is not designed to be tiles once installed. We would not recommend it in this particular project.

Can I use 'Mapei Mapegrip Plus Tile Adhesive' after the Aquadefense membrane has been applied to hardiebacker board for tiling?

Asked by: ChunLi
A D2T ready mix adhesive such as Mapei Mapegrip Plus can be used on the Mapei AquaDefense Waterproofing Membrane. It should be noted that the drying time will be extended.
