Short Summary
Main recommendation: Before stripping wallpaper, push on the wall; if it moves a lot, the paper may be holding up plaster, so consider covering it instead. For drywall, cut through the top decorative layer with a utility knife, soak the backing paper repeatedly with a sponge until the adhesive releases, then scrape the backing off with a four-inch drywall knife. The presenter stresses that many light passes beat aggressive scraping.
Key Points
- Test first: push against the wall. Heavy movement suggests the wallpaper may be holding the wall together, in which case resurfacing (wallpaper over wallpaper, or skim coating with drywall mud) may be safer than full removal.
- Remove the top decorative layer first, cutting it with a utility knife so the water-soluble adhesive underneath is exposed, instead of using a score wheel and chemical solution.
- Water is applied over and over rather than all at once; this is the core technique, not a single heavy soak.
- Painted drywall with a primer/sealer resists moisture, so it comes off relatively easily; raw drywall or plaster takes much more soaking.
- Don't fight the paper: if resistance appears, stop, because forcing it damages the wall and creates patches that need repair.
Details Worth Noting
- Concrete instructions:
- Push against the wall. If there is a lot of movement, do not strip it; consider wallpaper over the existing paper or skim coating with drywall mud.
- Use a utility (Alpha) knife to cut through and peel off the top decorative layer, exposing the backing paper.
- On drywall, use a four-inch drywall knife to scrape the backing. Plaster requires a specialty yellow razor-blade scraper (about five-inch blade, on a roughly 12-inch arm, set at about a 10-degree blade angle and about 20 degrees to the wall) used as a two-hand tool.
- Dampen the wall with a grout sponge. Use enough water to soften the adhesive but not so much that it runs down the wall and seeps behind the wallboard into the ceiling.
- Make repeated passes: soak, wait for the water to penetrate, scrape, then re-soak. Expect several runs; on a painted wall one or two passes may suffice, while raw drywall may take six to eight, and some paper may take eight soakings and nearly two hours per wall.
- Keep the blade nearly parallel to the wall when resistance appears; approach corners from the side, since drywall corners often curve.
- Re-wet the wall during work, because it dries out after a few minutes.
- After removal, let the wall dry, wipe it down, sand lightly, then patch and repair.
- The presenter notes that a score-and-chemical tool with a red top and score wheel is unnecessary, since cutting the top layer gives direct access and avoids puncturing the wall with many small holes.
- The wall may show patches after forced scraping, but these are repairable.
Bottom Line
Stripping wallpaper is mostly a matter of patient, repeated wetting rather than force; test the wall's structural integrity first and stop if it resists.
