Hi all,

The wallpaper in the bedroom was put on top of a painted wall. When we removed the wallpaper it pulled off some of the paint back to the plaster. We want to now just paint the wall. What is the best way to deal with this? Should I used a watered down paint again where the plaster is exposed? Also how do we stop the line between the originally painted bit and the now plaster exposed bit from being seen when we paint the wall?

Thanks in advance

Lee.

Use a thick, good quality lining paper that'll cover the imperfections.

That would be my strategy too. It needs to be well soaked, and applied
carefully, but with practice you can make the joins invisible under a
single coat of emulsion.

If the original paint was gloss, or multiple layers of emulsion, it may
be worth sanding to feather the "steps".
