I always Gardz right after wallpaper removal to seal any residual paste, skim, then Gardz again as my prime coat. But I'm wondering if Gardzing the whole thing prior to the skim is a wasted step. Will joint compound stick fine to the walls even if there's paste and DIF residue? I do mop down the walls after the wallpaper is down. Nothing super thorough...just a once-over, and I literally use a sponge mop.
If I have torn paper, obviously it's gonna get Gardz before mud. OBVIOUSLY! Sorry, I felt I needed to point that out.
Hey...while I'm at it, what's your favorite joint compound for skimming? Blue lid? Green lid? Honestly I never use green lid for anything except taping (and only because of the bond to paper)...am I missing out?
