I recently helped a friend with some decorating. We found the surface plaster had blown. so stripped it all off and had a plasterer redo it. He did a lovely job with the finish. and it's incredibly smooth to the touch.
He said to leave it a few days to dry, at which point it would be a fairly even pale colour, before then sealing it with PVA mixed in a ratio of 1:8 with water, so we left it a week and then did this. We then waited a further two days before applying Crown Silk-finish emulsion (2 coats, 2 day apart).
A week later, and the paint seems, however, to be very easily damaged, and can be peeled off the wall in a skin. We had a small piece of masking tape on the wall to mask off a corner when painting the skirting board, but the masking tape pulled the paint off into a bubble!
Is this likely to be a problem with the whole wall, and what can be done about it?
Why has this happened at all - we followed instructions from the plasterer to the letter!
Please help
