So I am in the process of painting the walls that had 40 year old wallpaper on them.
I got all the wallpaper off down to the plaster skim coat on the drywall. The walls are stained from the adhesive since I don't think they sealed the walls before papering. Looks almost like how nicotine runs look on a wall. I have already repatched a hole in the wall with joint compound and a piece of drywall, spackled all the nail holes (except a few left to go) and got everything looking awesome. I than sanded down the walls with 100 grit on a pole sander to smooth out the fixes and try to get any remaining adhesive off (some spots of the adhesive got blended into the surface and WILL NOT come off no matter what).
Well after finding out not everything came off, I gave the local Ben Moore store a call for advice on what to hit the walls with before painting with expensive paint. They recommended 2 things, INSL-X AquaLock and Zinsser GARDZ/ALLPRIME waterbased sealer. They said the GARDZ would seal in the leftover adhesives, etc so the aqualock and paint wont peel off and activate the adhesive again.
I decided to look into the sealer a little more and found out that I was supposed to seal BEFORE I patched or filled anything at all. The zinsser site states in the cans directions to fill/patch any holes, sand walls, etc before applying GARDZ. Most of the forums I have read about it on are saying to use GARDZ before spackle, compounding so that the spots you patch wont "peel" up? I am worried that when I go to apply it, all my hard work will be ruined.
Has anyone used this stuff and patched/sanded beforehand and had success?
Thanks.
