I had read that new drywall needs to be primed/sealed before trying to apply wallpaper; "Shieldz" was mentioned specifically, so I bought a qt. can of clear Shieldz (it's a small area). After applying one coat I checked online to see how long I should wait before applying the paper, only to find that they say that for use over mudded drywall I should use the white Shieldz -- but although it's made in quart cans nobody sells it in quart cans.
Is there a good substitute that might be available in quart cans?
