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.

Correct type of flooring

Will this be the correct waterproofing for standard 18mm domestic chipboard flooring with no waterproof membrane in a wetroom area? Mosaic tile floor covering and Kerapoxy grout to finish. If not what is recommended?
Asked by: Lincslandy
Chip board needs to be of P5 grade ,we would recommend over boarding with a suitable tile backerboard then applying the Mapei Mapelastic Aquadefence

Can this be applied directly to newly plastered walls?

Do I need to use a new plaster sealer before I apply this to new plaster or can it be applied directly to it?
