ok , I'm happy to accept that I'm wrong on the Pva thing , but not sure what the objection is on Bonding ????? , especially as it's been '' closed in '' by running a wet brush over it just before it sets , and bearing in mind that the original question was about a reasonably small patch area , I recon you'd '' get away with it ''
but I have'nt joined these pages to have a row , so I'll sit back quietly and shut up and see how this develops.
Just to clarify why not to then read num 13 on this link>>>>> Tiling to Gypsum Plaster
