Can any body help!! I've got some 600 x 600 polished porcelain floor tiles and want put them on the walls in my bathroom. Can anyone tell me if this possible? and if so can you recommend a good adhesive for the job. I have been told Stone Fix White rapid Adhesive might be good. The wall's they are going onto are bare plaster so not sure if they will need to be primed?

Check this site out it will give the answer, Tiles and Adhesive Weight Per Square Metre - THE TILE SOURCE

The tiles will exceed the weight of 20kg m2 for plaster

Bare plaster, is that finish plaster over a scratch coat over blocks, finish over plasterboard or scrstch over blocks?
Plaster board cant hold too much weight and if its plastered i wouldnt put 600x 600 on it.

I wouldnt use rapid set on walls, goes off to quick in the bucket. Use a good single part flexi, with a 4 (ish) hr pot life. Check with your local tile shop, it probably isnt self priming so prime the walls first.

Unfortunately the tiles you have are to heavy for your walls even the thinnest 600 by 600 porcelain tiles are 10mm thick and they will be 23.88 Kg/m2 and if they are 12mm they will be 27.82 Kg/m2 as it says in whitebeam’s link (excellent stuff by the way whitebeam) as for the adhesive it will need to be flexible cement based adhesive and the walls will have to be primed with acrylic primer as cement based adhesive will not adhere directly on to gypsum based backgrounds.

Spot on advice Deano, without priming, gypsum can react with cement based adhesive causing failure....
