A tiler friend of mine has just laid 60m2 of 300x600 porcelain on a very stable chipboard floor overboarded with 12mm ply. He grouted some of the floor then went back the other day to finish grouting only to find that some of the grout craking on previous grouted areas, so he tried to pop a tile wich came away clean and had not bonded to ply.
The overboarding was do a month prior to tiling and has now found out from the customer that she had been washing the ply with soapy detergent, ply had been bonded with a SBR primer (this was after she had washed floor) but could the detergent be the cause of the adhesive not bonding to ply??
