Looking for advice from Tilers who have used this stuff please.
Had wall re-skimmed prior to tiling above bath for shower use. Let plaster dry a couple of weeks then painted neat bonding agent on wall (as per instructions on container) before tiling. Have tiled one significant area of wall but now notice on another wall that bonding agent has stuck but can be peeled off like a skin from plaster - doesnt look like it has keyed as well I I would expect. Just phoned BAL who tell me I should have used 4:1 soution so as to soak it into plaster. Seems logical and I should have checked before however existing tiles seem to be reasonably well fixed and I cant pull them off by hand but I imagine they would come off if I got a scraper behind with tile and cement intact breaking seal between plaster and bonding agent.
Any help or advice would be appreciated.
