I have been removing approx. 20 yr. old wallpaper from drywall. The previous owners did not prime or size the wall first! Now I am left with walls that look like torn cardboard. What is the fastest and most cost effective way to get the walls in paint ready condition? Please help, I need this job done ASAP!
Thank You,
Leanne

You need to skim coat the bad places with Light weight drywall compound (mud).

And then sand it.

I have not used it, but the next big one that I do I am going to use a sealer on the DW first. There some products made for that purpose, but I don't remember the name.

If you can find them use BINS pignment shelac sealer.

After you coat it you will need to sand it and them probably go over it again.

You will have two problems. First there will be the little bits of paper that come off and leave tracks. Pick those out and go over it again.

The other is that sometimes the water from the mud will cause the paper to ripple. Sand down the light spots and coat again (and again).

Sealing before hand will help reduce both of those problems.

And after you are done you want to prime the whole wall with a primer/sealer. If you used the Bins, you can use that. Otherwise a latex sealer/primer like 1-2-3 will work.
