Please help I need a quick fix. Our tiler has expressed his annoyance because when getting rid of the excess paint on our rollers I painted over the sections underneath the kitchen units where he's going to tile. Because he always uses pva to seal the plaster he's worried about doing it a different way – apparently now he has to scribe the paint and then tile without using pva. Is this method ok or is there any other solutions. please respond quickly as he is due to start the tiling soon and I will have no come backs if the tiles fall off because I made the mistake of paintingn the plaster. Cheers in advance.
