Hello all, Just finished my small ensuite 1.5m2 area and I have just noticed that the grout has cracked. Under closer inspection all the tiles have not bonded to the ply. The tongue and groove floor was solid so i used 6mm wbp ply screwed every 150mm centers. I know 6mm ply has no structural benefit but provided a nice smooth surface. Adhesive was bal rapidset flexible which has never given me any problems in the past. I have thought of one possibe reason this could have happened.......as it was a small area I applied the adhesive to the tile then pressed them down onto the ply. The ply was not primed as recommended by Bal. Have I made a schoolboy error? Tiles from good old B+Q!
Any thoughts??
