Are the walls waterproofed? There could be damp trapped in there preventing the paint from adhering. The best solution is to apply PVA glue to the walls with a paintbrush, wait for it to dry, then apply a white undercoat and two or three thin coats of bathroom paint. Do not use the shower during this time

Hi.

I bought some Dulux Bathroom+ paint from B&Q today, it was from the paint mixing station.

I started doing the cutting in in the bathroom,going around the tiles etc, and then I went to have dinner and when I came back I was wiping along the edge of the tiles and the paint I had just applied just peeled right off the wall, it still had its elasticity, like peeling PVA glue off a hard surface?

Our house was totally re plastered about a year ago, and just had a plain white wash on the walls. I didn't have this problem when we painted the hallway, so what can I do to fix it?

If I water down some matt emulsion and coat the walls in that first, will that work?

Thanks for any tips and advice, I'm pretty annoyed about this seeing as I had done about an hour and a half's worth of cutting in ??
