I painted my bathroom, then woke up the next morning to find that half the paint from the top of the window wall had dripped back off again, leaving really big tear marks down the wall.
The bathroom was originally painted the blue colour. I sanded, applied sugar soap and waited till it dried, and just applied white paint as the color I am putting on is lighter. There was no silicone or anything. I just think the wall is that damp. The paint covered really well so I was all set to add the colour on top the next day. The wall gets damp overnight as do the window, toilet etc. from condensation I think.
I have really limited money and was advised to use PVA on the wall to seal it, then paint over that once dry to get the paint to stick.
Has anyone tried this and did it work?
