I just removed some wallpaper which left the walls not so nice and I want to paint them. I read in the forum about skim coating and would like to know what is involved and how difficult it is.

If you've removed wallpaper and there's any of the brown backing paper revealed, you'll need to prime with a product called Gardz, made by Zinnser prior to skim coating or else the mud will blister. Once you've got that sealed, use lite joint compound thinned with water and a wide drywall blade to skim out the wall and get back to a smooth flat surface.

Larry,
I just got done doing a bathroom over with the same problem. Had a new shower installed,(plumber destroyed the wall) and I decided to take off the wallpaper only to find out why it put it up in the first place (to hide the wall damage).Like Awesomedeel mentioned get a sealer/primer, I used glidden Ultrahide myself. What kind of damage do you have? If it is just pitted or holes, I would just patch them up with joint compound than sand down, and paint over with a really good sealer/primer. A good primer/sealer can hide,minor damage, and using a flat paint works better to camo the damage rather than a glossy satin that tends to highlight flaws.
If you chose to skim coat, which I did to blend in the plaster wall with the drywall I installed. You mix up the topping joint compound (make sure to get ready mixed compound) with water to a milk shake conistantcy. Sread it on the wall with 3/8 inch nap paint rollar, than use a taping knife/trowel to spread it out. On a sidenote,I would only recomend skim coating if your going to paint the room with a high gloss paint, if not, a really good primer-sealer can hide the flaws, along with some minor spackle work.

Pretty good advice there Kevin, although I would recommend using Lite Joint Compound rather than topping mix.
