Help please...about a week ago, I finished tiling my ensuite and have now noticed that the edges of some are lifting....having prised a couple off it appears that the adhesive just hasn't stuck to the ply at all.
Tiles are 250 by 400 ceramic, walls are 12mm wbp very securely fixed, on studs at 300mm and screwed every 200mm vertically.
Adhesive was Instarmac Ultra Waterproof WR reccomended by my local tile "expert" and used slightly against my better judgement as I was going to use bagged with an additive for wood. Adhesive datasheet does tick all the boxes though but that doen't help me now.
The shower is tanked with Mapeigum up to 3/4 height and the tiles appear to be stuck OK here....one wall is plastered and again tiles appear to be stuck OK.
Any input as to what went wrong, the best way to fix it and what I should use when fixing would be much appreciated.
I've tiled at least half a dozen bathrooms onto ply with no problems before so I don't understand what went wrong this time.
Thanks
