Rated 5 out of 5 by from This 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 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...!

Rated 5 out of 5 by from Great product Used many tanking systems and this one is great dries quickly and covers very well with a roller or brush, handy to be able to buy it in a large quantity aswell .

Can I silicone seal a bathtub onto aquadefence?

Can I coat a bathroom in aquadefence then seal the bath onto it or should I seal the bath first and paint aquadefence up to the bath then tile? Hardibacker walls. Thanks
Asked by: Byofish
Mapei Aqua Defence can be used on Hardie Backer, we would recommend tanking the walls/floors first then tiling, sealing the bath would normally be done last. Please contact our Mapei Technical department who can asset you further.

Can you Wallpaper over this product?

I have a problem with damp walls, It's an old building. Lining paper was used before painting, however, it's lifting in some places & there's black mould in 1 corner of a room. I am trying to find out the best solution to sort my problem.
Asked by: DIYerC
Unfortunately this product cant be used on wall paper. AquaDefense is used to form waterproofing layers before applying ceramic, stone and mosaic tiles. It can be used in showers, bathrooms balconies and terraces. It is used to stop water getting into the background.

Can this product be painted over afterwards

Asked by: Scooby111
Mapei AquaDefense Waterproofing Membrane is designed to waterproof surfaces prior to the application of tiles, it is not recommended to paint over this product.
