How to Remove Wallpaper: A Step-by-Step Guide

Updated: Aug 2026

Stripping old wallpaper properly is the single biggest factor in how well a re-paper or repaint job turns out — paper over old paper, or paint over a poorly stripped wall, and the seams, bubbles, and old adhesive show through eventually. It's also more predictable than most people expect once you know which method suits your paper and your walls. Here's a step-by-step approach that works whether you're dealing with a single feature wall or a full room.

Identify the paper type before you start

Standard paper-backed wallpaper soaks and strips relatively easily. Vinyl or vinyl-coated wallpaper has a waterproof top layer that stops water reaching the backing paper, so it needs scoring first — a scoring tool or light sanding to perforate the surface — before any water-based stripping method will work. Trying to soak an un-scored vinyl paper wastes hours; check which type you have with a test patch in a corner before committing to a method.

Score, soak, and scrape is the reliable default method

For most papers: score the surface (skip this step for plain paper-backed wallpaper), then apply warm water with a little washing-up liquid or a wallpaper stripping solution using a sponge or garden sprayer, and let it soak for 10–15 minutes. Use a stripping knife or a wide scraper to lift the paper from a bottom corner, working upward in broad sections rather than small scrapes. Re-wet stubborn sections and give them more time rather than forcing a scrape that gouges the plaster underneath.

A steam stripper earns its cost on a full room or stubborn paper

For a full room, multiple layers of old paper, or paper that isn't responding to soaking, a steam wallpaper stripper (hired or bought) speeds the job up significantly. Hold the steam plate against a section for 10–20 seconds, then scrape while it's still hot and pliable, moving to the next section. It's genuinely faster on a large area but adds a cost and a learning curve on a single small wall.

Protect the wall surface — plaster damage costs more than the wallpaper did

Aggressive scraping, especially on plasterboard, gouges the paper surface of the board itself, creating a rough patch that needs skimming or filling before any new paper or paint goes on. Work with patience on stubborn sections — more soaking time, not more scraping force — and expect to do minor filling and sanding afterward on most walls regardless of technique.

Clean and prime the bare wall before you hang anything new

Once the paper is off, wash the wall down to remove old adhesive residue — leftover paste can prevent new wallpaper from bonding properly. Let the wall dry fully, fill any gouges or holes, sand them smooth, and apply a wallpaper size or diluted PVA primer before hanging new paper. Papering straight onto a bare, unprimed, freshly stripped wall is one of the most common causes of a new job failing early.

Painted-over wallpaper needs extra scoring, not more water

Wallpaper that has been painted over resists soaking, because the paint seals the surface almost as completely as vinyl does. Score it more heavily than a plain vinyl paper — several passes with a scoring tool in overlapping directions — and expect the soak time to run 20-30 minutes rather than 10-15. A chemical stripping gel formulated for painted paper often outperforms a plain water-based solution here, since it clings to a vertical surface longer instead of running off.

Protect switches, sockets, and flooring before you start soaking

Turn off the power to the room at the consumer unit before soaking wallpaper near switches or sockets — warm water and a sponge close to live fittings is a genuine shock risk. Fit socket and switch covers or tape over them as a second precaution. Lay dust sheets and towels along the skirting to catch runoff, since a full room of soaked paper drips more than expected, and standing water on laminate or wood flooring can cause it to swell.

Common questions

What is the easiest way to remove wallpaper?

Score the surface if it's vinyl or vinyl-coated, soak it with warm water and washing-up liquid (or a stripping solution) for 10–15 minutes, then scrape from a bottom corner upward in broad sections. This score-soak-scrape method works on most walls without special equipment. A steam stripper speeds up a full room or stubborn multi-layer paper.

Do you have to remove old wallpaper before hanging new wallpaper?

Yes, in almost all cases. Papering over existing wallpaper risks the old seams, bubbles, or pattern showing through, and the old paper's own bond to the wall may fail under the added weight and moisture from new paste. The one exception is a sound, single layer of lining paper specifically intended as a base — old decorative wallpaper should always come off first.

How long does it take to remove wallpaper?

For a single room (around 30–40 m² of wall), expect 3–6 hours of soaking-and-scraping for straightforward paper-backed wallpaper, or 2–4 hours with a steam stripper on a stubborn multi-layer job. Vinyl papers that need scoring first add extra time. Budget more time than feels necessary — rushing the scrape is what damages the wall underneath.

Can you remove wallpaper without wetting it?

Dry stripping is possible with a steam stripper, which uses heat rather than soaking, or on papers designed to peel — some paste-the-wall vinyls strip off as a dry, intact sheet, leaving the backing paper behind. Standard printed paper almost always needs water or steam; dry-scraping it alone gouges the plaster.

How do I dispose of stripped wallpaper?

Wet, scraped-off wallpaper is heavier than it looks and goes in general household or garden/DIY waste, not recycling, since it's saturated with paste and sometimes paint. Let large sections dry out before bagging if bin capacity is limited — it reduces the weight substantially.
