Hi, I've pulled the old tiles off the walls in my kitchen and bathroom and the surface underneath is interesting! The plaster is generally sound except for the fact that maybe 50% of the skim coat came off. So I've scraped off the rest of the skim coat and am left with the main plaster bonding (?) coat. My question is can I just tiles straight onto this or do I need to prime it with anything? I understand PVA is not the right way to go, but do I actually need to do anything? I've got 600x300mm porcelain tiles and bags of powdered adhesive. Cheers
you will be fine to put the tiles straigth onto the bonding plaster. just make sure its free from any loose plaster or dust.
With really dry flakey old plaster I have used waterproof PVA to great effect to toughen up the surface of the plaster. Been doing it for years and never had a problem yet.
Oh dear .......... I can see another 10 page PVA debate about to kick off ....... Bring it on ......................................................................................................................
