How to Remove Wallpaper
Whether you're refreshing a room or prepping for new paper, removing old wallpaper is straightforward once you know which type you're dealing with — and once you accept that the water does most of the work, not the scraping.
The hands-on method below comes from professional installer Matthew Williams of MWD Interiors, who has been decorating interiors since 1994.
Before you start
- Clear the room or move furniture to the centre and cover it with drop sheets, then cover the floor.
- Cut the power to the room at the fuse box, and tape over any nearby power points. This is a wet job, and water plus electricity is dangerous.
- Matthew's tip: roll up old beach towels into tight "sausages" and press them along the base of the wall to catch the run-off before it reaches your floor.
First, find out what you've got
Pick at a corner with a scraper and lift.
- If the paper peels away dry, in one layer — you likely have a modern strippable or peelable paper. Lucky you; this is the easy case.
- If it tears into small bits and clings — it'll need soaking to release the paste.
- If it won't budge at all — it's a traditional paper that needs water and a stripping solution (see Matthew's method below).
The easy case — strippable paper
- Lift a corner with a scraper.
- Pull gently and steadily at an angle. It should come away in large pieces.
- Wash any remaining paste residue off the wall with warm soapy water and let it dry.
The soaking method — for stubborn paper
You'll need: a sponge or garden sprayer, warm water (a little washing-up liquid helps), a scraper, and patience. A scoring tool helps on water-resistant papers — it makes tiny holes so water can reach the paste.
- If the surface is water-resistant, gently score it all over with a scoring tool. Don't gouge the wall.
- Wet the wallpaper generously with warm water and let it soak in for a few minutes.
- Re-wet if needed — the paste needs time to soften.
- Slide your scraper under the paper at a low angle and lift it away. Keep the scraper flat so you don't dig into the wall.
- Work in sections, re-wetting as you go.
Matthew's installer method (the one the pros use)
For traditional, textured (such as Anaglypta or seagrass), painted-over, or otherwise stubborn wallpaper, this is the professional approach.
You'll need:
- Hot, hot, hot water — the hotter the better
- A bottle of Zinsser DIF wallpaper stripping solution (about $20 from Bunnings) — optional, but it makes the job dramatically easier
- A 5-litre pressurised pump spray bottle (from the garden section at Bunnings)
- A snap-off blade knife and spare blades
- A plastic scraper (a plasterboard/gyprock blade is ideal — it won't scratch the wall)
- Old beach towels
Method:
- Fill the spray bottle to the 4-litre mark with hot, hot water and add a good splash of DIF.
- Lightly score the surface of the wallpaper with a sharp blade in a diamond pattern — parallel lines roughly 200–300mm apart. This lets the water get behind the paper.
- Pressurise the sprayer and soak the wall several times.
- Start gently peeling and scraping with the plastic blade.
- If it isn't lifting easily — soak it again. Patience here is everything; the water does the work, not the scraping.
- Keep those rolled beach towels at the base of the wall to mop up the run-off.
"The way to strip wallpaper easily involves a lot of water — so turn off the electrics and use those beach towels to soak up as much as possible." — Matthew Williams, MWD Interiors
On a budget? Some people swear by diluted fabric softener or vinegar in warm water as a cheaper alternative to a chemical stripper.
A faster option — a steamer
If you've got multiple layers, a wallpaper steamer (hire one cheaply) speeds up tough jobs. Hold the plate to the paper for a few seconds to loosen the paste, then scrape. Keep it moving so you don't scorch the wall, and wear gloves — steam is hot. Treat it as a last resort, and work with a friend if you can.
Finish the wall properly
Once all the paper and paste are off:
- Wash the wall down to remove every trace of old paste (new paper won't stick over old paste).
- Don't over-soak plasterboard (drywall) — it can be damaged if it gets too wet, so soak enough to lift the paper but don't drown the wall.
- Let it dry fully.
- Fill, sand and prep — see Prepping Your Walls — ready for your new wallpaper.
Take it gently
Don't gouge or rush — damaging the wall surface just creates repair work later. Soak, wait, and let the water do the hard part.
