hi when you say mould

what colour? black? does it wipe away, if so , warm water with bleach will wash off and kill and mould thats formed on the surface.

hi a good wipe with bleach then a good sealergoat ,let it dry for 24hrs then tile away

 

[peckers]

most paint shops do a mould remover and preventative to stop it from coming back, treat it with these then wash down with clean water and then allow to dry

thi is really good stuff for removing mould, I've used it and it was brilliant

Is there any paint on your walls and is it a vinyl silk

Once the mould has gone, tank the shower / bath walls, this will help prevent mould growth in the future

 

[jcharris]

black mould and wipes off but but leaves a stain. what does tank mean?

 

[Aston]

'tank' means to waterproof the substrate ie wall/floor

right to do it the correct way chop out odl plaster and replaster because the old plaster will have spores and be damp you dont tile full stop on a damp surface one you have replasted prim it with primmer t you can used board adhesive to plaster this is water poof if you going to the job dont cut cornars it will come back and bite you in the butt big time
