Hi all, I've lurked on this forum and got lots of tips but never posted before. My Dad and I are redoing by bathroom and learning as we go along. All the plumbing is now done so we had the whole room replastered (green board). I mist coated the whole room and now I'm worried that was a mistake as I've now read that you shouldn't tile onto paint. Does it help that it's only a very thin coat?! Or do I need to remove it now? Should I prime the wall? I'll be using Mapei Keraflex S1 with 150mm square tiles. Thanks in advance for your advice. Laura.
