How to remove wallpaper without damaging your walls

Almost all the damage done when removing wallpaper comes from two mistakes: forcing dry paper off the wall and scraping with a sharp tool. The fix for both is the same: patience and water. But the right method depends on what the paper is made of and what kind of wall it's on. In this post we go through both, one at a time.

First, get to know your wallpaper

Use a thin putty knife to lift a small corner at a seam, then pull:

The soaking method: the basic technique for pasted wallpaper

For any wallpaper hung with paste (non-woven included), this is the safest approach:

1. Cover the floor, tape over outlets and switches, and if you can, switch off the breaker for the room.
2. Add a little dish soap or white vinegar (up to 1:1) to warm water. Apply it generously to the paper with a sponge, roller or spray bottle.
3. Wait 10–15 minutes. Skip this step and you start scraping before the water has reached the paste, which is the number one cause of plaster damage.
4. Pull the paper slowly from a corner, at a low angle close to the wall. Don't force areas that resist; soak them again and wait again.
5. If you need a scraper, use a wide plastic one or one with rounded corners, and hold it parallel to the surface.

On vinyl-coated wallpaper, water can't get through the surface, so you first score it with very light pressure (shallow enough not to reach the plaster), then soak it. Non-woven doesn't need this: because the backing breathes, water reaches the paste without your having to score the pattern.

For self-adhesive wallpaper: heat, not water

With textile-backed or film-type self-adhesive wallpaper, the adhesive isn't on the wall; it's on the back of the paper itself. Start at a corner and pull the paper at a low angle close to the surface, from top to bottom, at a steady pace. If it resists, soften the adhesive by moving a hair dryer on low over it from 10–15 cm (about 4–6 in) away; don't hold it in one spot. Heat loosens the adhesive and lowers the risk of paint coming off with the paper.

Why does the type of wall matter?

• Gypsum plaster / skim-coat plaster (the most common wall surface in Türkiye): it stands up to water but not to sharp scraping. As long as you soak and wait, you're safe.
• Drywall (partition walls): its paper facing is affected by both too much water and steam. Use water sparingly; don't hold a steamer on one spot for more than 30–45 seconds, and if you can, don't use one at all.
• Painted surfaces: flat paint partly absorbs water; on satin or washable paint the water sits on the surface, so wait longer.

A few small marks after stripping are normal: fill small dents with spackle, sand and prime.

Paste residue: an invisible but important step

Once the paper is off, a thin film of paste that turns shiny when dry is often left on the wall. What you do next depends on your goal:

If you're hanging new wallpaper: clean off as much residue as you can. Wipe it with warm soapy water and a sponge; on stubborn spots, use a 1:1 vinegar and water mix. When you run your hand over it, the surface should feel smooth, not sticky; new paste doesn't bond well over old paste.

If you're painting: wiping the wall down to zero residue often isn't realistic, and you don't need to. Here's what matters: wallpaper paste is water-based; if water-based paint goes straight on top, the water in the paint reactivates the paste and the paint bubbles and cracks. The solution is to take off the rough residue with light sanding and a damp sponge, then apply a sealing (barrier) primer before painting: a solvent-based primer, or a filler primer made for problem surfaces that forms a moisture-proof film. A standard acrylic primer won't do the job; it's water-based too, so it can wake the paste back up. Once the primer is dry, spackle, sanding and paint follow in that order. Don't move on to the next steps until the wall is completely dry.

Frequently asked questions

Can removed wallpaper be reused?

No. Wallpaper hung with paste stretches as it comes off and the paste layer breaks down, so it can't be hung again. That's why it matters to get your measurements right from the start; we explain how in our measuring guide.

Should I use a steamer?

On plastered walls, it helps with stubborn, multi-layered old wallpaper; it isn't recommended on drywall. For a typical DIY removal, warm water plus waiting is usually enough.

How long does removal take?

With a single layer of wallpaper, an average wall comes down in a few hours. If there are old layers hung on top of each other or painted-over paper, it can stretch to a full day; the layers are loosened one at a time.

Can I paint the wall after removing wallpaper?

Yes, but with a sealing primer in between. If water-based paint goes directly over paste residue, it can bubble. Remove the rough residue, apply a barrier primer, then paint.
