hi all, i am currently removing some bathroom tiles...i have taken off quite a few so far and have reached what i assume is the plastered wall...it is kinda sandy & dusty.i have taken off the tiles & the old fixative..there are very very few what i would call holes ( about the size of a 10 pence piece or so...my question is..will i be able to tile straight onto what i called the plastered wall?( i mean after giving it a good hard brushing off & filling the litle holes)..many many thanks in advance

Knock on the plaster and see how it sounds.If it sounds hollow then it would really need stripping off and replastering/plasterboarding.
If it sounds solid then you will need to clean off the dust,fill the holes and prime it.
In a shower/wet area tank it in other areas use acrylic primer.
If the surface is really dusty/crumbly it would probably need stripping as above.

This is the one I use

Tanking is something you do in a shower/wet area,basically painting on a waterproof coating to stop water ingress into the substrate.
