<p>Is it a paper or a vinyl? If it’s a vinyl surface, normally used in kitchen and baths, it may be a “peelable” vinyl. This very simply means that the vinyl surface can be peeled from the paper backing. This exposes the paper backing which is adhered to the wall. Trying to get your stripper, hot water, or fabric softener solution to soak through a vinyl surface is a waste of solution.</p>
<p>Stay away from the wheel thingy (Paper Tiger is Zinsser’s trade name for this device) if you have sheetrock, and not plaster. You can be as agressive as you want with that little sucker on hard, sound plaster, but if you press too hard on drywall, you’ll leave a gazillon tiny holes in the surface of the drywall. Depending on how hard ypu press, you may be into skimcoating the drywall to prep for new paint or paper. Sometimes these holes may cause lifting/peeling paint conditions down the road, especially in heavily damp environments, like a bathroom. The trick with this tool is knowing your underlying surface, and gauging your pressure as to only perforate the surface of the wall paper, not the paint layer or drywall paper surface underneath. </p>
<p>Properly prepped walls (primed and sized) speed the process of removal. If you have paper
hung on raw, unprimed sheetrock, you are in for a headache. It will not budge without causing major drywall repairs necessary. It’s best just to paper over the existing paper if it’s sound. A job best left to pros, and a number of pros don’t recommend paper over paper. A flat 4 or 6 inch taper’s knife (putty knife) held flat helps to remove large loose pieces once the stripper works. Don’t use a razor scraper often sold as a wallpaper removal tool. These are meant to be used on plaster, not drywall. </p>
<p>The paste used in hanging the paper is another issue. Prepasted papers soaked and hung without a paste activator are the easiest to remove. The standard vinyl pastes (except those for vinyl over vinyl applications) are also fairly easy. The heavy duty or clay based pastes, normally used in hanging heavy papers are notoriously hard to remove, can be time consuming, and require multiple wall washings to eliminate all paste residue.</p>
<p>Steam is effective, but you can overdo it, breaking the seal of underlying paint to drywall or the paper layer to the rock’s gypsum core.</p>
<p>Take your time. Soak the surface, let the stripper work, and work in small sections lest it dry out. When it wants to come off, you’ll know. I’m not a fan of the gel strippers, they are messy. Zinsser’s DIF is too sudsy in my opinion, requires too much rinsing and cleanup. If you can find it, Imperial’s wall paper remover concentrated solution (mix with water) is the most effective.</p>
<p>Edit: As for the remaining glue residue, you’ll have to do a complete wash and rinse afterwards (or as you go along). Try one of the heavier scotchbrite type pads for the wash (brown in color, available at paint centers). The aggressiveness of the pad is a function of color: the white pad is the softest, the black is most aggressive. Rinse the surface with clean, hot water, and a GOOD sponge. I prefer the grout sponges, they don’t disintegrate. If you don’t get all the residue, it is notorious for coming off in your roller and brush when you go to repaint. </p>
<p>Good luck. Sometimes it will take you 4 times as long to strip a 5x7 bath than a 16x18 dining room.</p>
