How to remove wallpaper properly – clean & quick

Stripping wallpaper has a worse reputation than the job actually deserves. It only turns into hard work when you work too dry, too impatient, or with the wrong tool. With warm water, a bit of waiting time and a scraper that really cuts, the strip often comes off the wall in one piece – and the surface underneath is ready to paint the same day.

Identify first, then wet

Everything else depends on what's actually stuck to your wall. The three most common cases behave completely differently once water comes into play.

Woodchip and paper wallpaper

The friendliest case. Paper absorbs water, the paste underneath dissolves, and the strip can be peeled off after a short soaking time. Woodchip that's been painted over several times takes longer, because the paint layer keeps the water out – here it helps to roughen the surface first with a spiked roller or the scraper.

Vinyl and painted wallpapers

Plastic-coated surfaces don't let water through. You first strip off the top layer, usually dry and in large pieces, and then soak the paper backing left behind. Two passes, but each one simple on its own.

Non-woven wallpaper

Non-woven is the special case everyone's glad about: it can usually be pulled off the wall dry, in whole strips. Start at the bottom in a corner and pull evenly upwards. If any paste remains, wash it off just as you would with any other wallpaper.

Why the old covering has to disappear completely

It's tempting to leave stubborn remnants in place and just paint over them. That reliably backfires.

Paint needs a solid base

A coat of paint is only as firm as what it sits on. A strip of wallpaper that comes loose in two years' time takes the fresh paint with it. Surfaces need to be clean, dry, stable and free of loose material – that applies to wall paint just as much as to new wallpaper.

Paste draws in moisture

Old paste swells up under fresh, water-based paint. You'll see it as a bubble or as a glossy patch that dries looking different from the rest of the wall. Washing it off completely isn't perfectionism – it's part of the job.

Edges show through

Every leftover strip edge is a step. Under a matte finish you'll spot it instantly in raking light, especially on large walls next to a window. If you don't fill the edge before painting, you'll be filling it afterwards.

What you'll work with

The list is short, but every item earns its place. Have everything ready before you wet the first strip.

• Spray bottle or sponge and a bucket of warm water
• A splash of washing-up liquid or wallpaper stripper
• A double spring scraper for lifting and pulling off
• A filler lifter for the touch-ups later
• Spiked roller or wallpaper perforator for painted surfaces
• Plenty of dust sheets for floor and furniture
• A microfibre cloth for wiping down
• Bin bags, so wet scraps go straight in

A good scraper saves you an hour

The difference between a blunt hardware-store scraper and a flexible blade with a clean edge is bigger than you'd think. The flexible blade follows the wall instead of digging into the plaster – and it's exactly the gouges a too-stiff scraper leaves that you'll be filling in again afterwards. You'll find more tools under Filling & Repairing.

Water is the real tool

It's not force that loosens the wallpaper, it's soaking time. Warm water with a little washing-up liquid gets into the paper fibres better than cold. Work in sections of about two strips, so the area you wet first doesn't dry out again before you get to it.

The first three steps: room, water, waiting

The start decides how clean the day stays. Wet wallpaper scraps on unprotected parquet are a project all of their own.

1. Clear and cover the room

Take furniture out or move it to the middle and cover it, remove rugs, cover the whole floor. Switch off the fuses for the room and tape over sockets and switches – you're working with water right on the wall. Protect skirting boards if they're staying.

2. Wet it down, evenly and patiently

Use a spray bottle or sponge to wet the surface evenly, without flooding it. Go over it a second time after a few minutes: the first pass opens up the paper, the second reaches the paste. On painted surfaces, roughen them up first, otherwise the water just beads off.

3. Let it soak

Now do nothing. The waiting is the part of the job everyone wants to skip, and it's the part that saves you the most effort. Use it to wet the next section – that way you're always occupied, but never too early to start.

Steps four to six: strip, clean off paste, smooth

From here it moves fast, if the groundwork is right. And it moves in small steps if it isn't.

4. Loosen and strip the strips

Set the scraper at a seam or a loose corner and lift the strip. Pull it off flat and downward, not straight out from the wall. If a piece resists, wet it again rather than tearing it – torn scraps cost more time than a second spray round.

5. Wash off paste residue

Anything that still shines or feels sticky is paste. Wash it off with warm water and a sponge, changing the water several times, otherwise you'll just spread the paste around. Finish with clean water and let the wall dry.

6. Fill and sand

Now the bare wall shows everything: cracks, plug holes, scrapes from the scraper. You can fill them with Spachtelmasse repair filler 1 kg, which handles easily and has strong filling power. Once it's dry, sand it level, for example with the sanding block – grit 120, and remove all the dust.

Where things typically go wrong

Three patterns repeat in almost every home – and all three have the same fix: more water, more time.

Working too dry

Anyone who starts pulling after a minute tears off scraps and ends up working in centimetre-sized pieces afterwards. Better to wet it twice and wait until the paper looks dark and soft.

Scraping with too much force

A steep scraper angle digs into the plaster. Each of those gouges becomes a filling job of its own later. Hold the scraper flat and read resistance as a signal, not an obstacle.

Leftover paste

The most invisible mistake with the biggest effect. Check the dry wall with your palm: if it feels smooth or slightly sticky anywhere, the sponge needs to go there again.

Time, water and quantity: what to expect

Good planning takes the fear out of the project, because it shows it's a day's work, not a week's.

Time frame per room

An average room with woodchip wallpaper is a one-day project if you work as a team of two: one wets it down, one strips it off. Wallpaper painted over several times, or vinyl, needs a second pass and so significantly more time. Factor the drying day afterwards firmly into your plan.

How wet the wall is afterwards

After washing it down, the plaster is damp. Ventilate thoroughly and give the surface time before you fill or paint – no coat of paint dries evenly on a wet wall. A room that's finished after painting is usually back to normal use after about 24 hours.

How much paint you'll need afterwards

Measure the wall surface while it's still bare in front of you. For two coats: 2.5 L covers approx. 8–10 m², 5 L approx. 15–20 m², 10 L approx. 30–40 m². All shades are listed under Colours.

From bare wall to fresh surface

The unpleasant part is behind you. Now comes the part you did all this for.

Priming absorbent surfaces

After stripping, the plaster often absorbs unevenly. Priming isn't essential, but it's worth doing on very absorbent or fresh plaster: it helps the paint dry evenly and reduces how much you need.

White as a calm base

If you simply want the wall bright and even, re-box prime WHITE (matt) is the obvious choice: very high opacity, an even finish and a calm surface that holds up even on walls sensitive to raking light.

Tape up before the first stroke

Skirting boards, door frames and window frames are now fully accessible – the perfect moment to tape up. For truly crisp edges, see How to tape up without paint bleeding, and for the full wall prep, see Preparing your walls properly.

Frequently asked questions about removing wallpaper

Can I paint directly over old wallpaper?
Only if it's firmly attached everywhere, has no open seams and no plastic coating. As soon as a strip comes loose or an edge lifts, the new paint will pull it up with it – in that case, removing it is the quicker route.

How do I remove woodchip wallpaper that's been painted over several times?
First roughen the paint layer with a spiked roller or scraper so the water can actually get through. Then dampen it twice, let it sit longer than with untreated wallpaper, and work in small sections.

Do I need a steam wallpaper stripper?
Not in most homes. Warm water with a splash of washing-up liquid and enough soaking time reliably dissolves ordinary paste; a steamer really only pays off with multiple layers or very old paste.

When can I paint after removing the wallpaper?
Only once the wall is completely dry and doesn't feel tacky anywhere. The surface needs to be clean, dry, stable and free of loose bits, otherwise the paint will dry patchy.

Do I need to fill the wall before or after?
After. First the wallpaper comes off completely, then the paste gets washed off, and only on the dry, clean wall can you see which holes and cracks actually need filling.
