Has anyone experienced problems painting silk emulsion on silk? You hear of problems painting matt on to silk but not really silk on silk. The wall was painted with a white silk emulsion (Leyland Contract Silk) about two months ago but I wanted to add a bit of colour. I bought a pot of B&Qs colours silk and when opening the container the paint was coagulated much more than I had experienced in the past. Even after stirring i had to scoop out a lot of the coagulated paint. Luckily the wall was small so didn't have to worry about wastage. Having applied two coats and let them dry, I started to remove the masking tape and the whole thing peeled off the wall (see photo). I appreciate silk isn't as permiable as matt however i didn't expect the new coats to come away as it has. So the question is; is the B&Q paint at fault (really didn't have the right feel or consistency) or is it the base silk coat? Or could it be both? I'm not sure if i need to take a fine sander to the wall next time. I might do that anyway.
