Hi, just about to start tiling a 2 sq.m plywood floor with ceramic tiles. 18mm Plywood floor directly onto braced joists, screwed at 250mm centres. Just finished tiling the walls using Mapei Keraflex and like the product and would like to use something similar for the floor tiles. Is the Mapei range of adhesives that are available in B&Q the same as Mapei's own stuff and do they sell anything suitable for fixing ceramic tiles to plywood?

The buildfix range that B&Q sell is made by Mapei but down to a price, it is not the same.

Mapei keraflex can be used on the ply too,or if you want a quicker set use the keraquick,its an S1 grade and can lift to an S2 grade if you mix it with the latex liquid instead of water! very flexible with the latex
