Need some info on redoing my walls. I had a game plan in mind and already have the wallpaper off but decided to do research anyway just because I dont have much experience with plaster walls. Turns out everyone and their brother have a different opinion on the procedure and materials. I've got 2 walls that are drywall and damaged from taking the wall paper down, the rest are plaster with some light cracking and previous paint still on. My plan was to fix the few spots and fill some holes and then prime everything with an oil based primer/sealer. Then move on to skim coating all the walls with mud for a smooth finish, then prime over that and then pick a color to paint. Any input is appreciated, thanks!

The procedure you outlined is almost exactly what I would do. If the cracking in drying cracks (spiderweb) in the white coat only, those are the kind that were there from day one, and have never moved, they are just a terrain feature.

If there are movement/settling cracks, then use fiberglass mesh tape and Durabond setting-type mud for the first coat, and use regular green-lid mud for the skim.


For the drywall walls, before you do anything else, use Zinzzser (sp?) Gardz to stabilize the drywall. It's designed to lock any old wallpaper paste in place, and coats any damaged drywall paper so that it'll hold paint or any skim coating you use. If you don't use it, you run the risk of having moisture from the paint/skim coat activate the wallpaper paste and/or cause the underlying paper to swell, making the paint/skim coat subject to possible separation and failure. I've used it a couple of times and it's always worked for me.
Thank you both for the helpful replies

Sounds good to me.  For the cracks I would cover the cracks with paper drywall tape, float over and taper to hide.  I would also use hot mud, 45 minute.  Found in powder in the drywall section.  I would also consider sizing the walls with fabric like they use to do, when the walls are completed.  Add, if missing, the picture mold for use when hanging pictures; to avoid putting nails into your plaster walls.  If you use paper tape, submerge each strips in water first, than add the mud. Your good to go



Would love to know how this works out. In our beloved c. 1872 farmhouse, pretty much all the walls are plaster and were covered by wallpaper (sometimes several layers). When we removed the paper from the kitchen walls AND ceiling (yes, the ceiling) to remodel the kitchen, and when we removed two layers of wallpaper from our bedroom and had those walls replastered, cracks appeared in LOTS of places, including the ceiling. In the foyer, which is papered, you can see some cracks underneath the paper, and they are present in pretty much all the ceilings on the first floor. Recently, we had some water damage in our "music room". Our insurance will cover almost all of the repairs needed, and we are trying to decide whether to re-paper (the stuff that is there at present is expensive it gathers dust and is not replaceable) or try to paint the whole thing. What are the odds that if we plaster, we won't get lots of cracks again?
