How do you remove paint from a wall?
Most painted walls do not need stripping, because sound paint can be cleaned, keyed and painted over. Where paint is flaking or the wall needs a bare finish, it is removed by scraping, chemical stripper or heat, but old paint in older homes may contain lead.
Last reviewed:Does the paint really need to come off?
Most of the time, no. Paint that is firmly stuck to the wall makes a good base for new paint. A wash to remove grease and dirt, a light key with fine abrasive paper and a suitable primer where needed are usually enough.
Paint needs removing when:
- it is flaking, peeling or bubbling, so new paint would come off with it
- there are many thick layers hiding detail or cracking
- the wall needs a bare surface, for example for a new plaster skim that needs a sound bond
- a previous coat was the wrong paint, such as gloss on a wall you want to finish in a breathable paint
On old plaster, flaking often means damp. Find and fix the cause first, or the new paint will fail too. Our painters and decorators page covers the trade.

What are the main ways to remove paint?
Scraping. Loose and flaking paint lifts off with a scraper. It is the starting point for most jobs and makes little dust if done carefully.
Chemical stripper. A gel or paste softens the paint so it can be scraped away. It suits detailed areas and many layers. Strippers carry safety warnings, so read the label. HSE explains that hazard pictograms, shown as a diamond with a red border, alert us to a hazardous chemical that might cause harm [S3].
Heat. A hot air gun softens paint so it scrapes off. It suits thick layers on woodwork more than plaster walls, which can crack or scorch.
Wet abrasion. Wet abrasive paper smooths edges and keys the surface with much less dust than dry sanding.
Steam. Steam strippers are mainly for wallpaper, but they can help lift some paints from plaster.
Power sanders and grinders make a lot of fine dust and are a poor choice on old painted walls.
Why does old paint need extra care?
Older homes may have lead paint under newer layers. GOV.UK says leaded paint may still be found in older properties, often below newer non-leaded paint [S1]. It says that if paint is in good condition or the property has been redecorated, the lead should be sealed in, and exposure is only likely if paint is removed or sanded [S1].
HSE's guidance for the building trade says to leave in place paintwork that is in good condition or covered by non-leaded paint, and only strip back old paint if it is flaking, chipping, giving off dust or is a risk to children [S2]. It says not to overheat leaded paint with blow lamps or gas torches [S2], and lists chemical stripper and wet abrasive paper among the lower-dust methods [S2]. It also says to keep children and pregnant women away from the work area [S2].
If you live in an older house and the paint needs stripping, a decorator who knows how to deal with lead paint is a sensible choice.
What if the wall has a textured coating?
Some walls and ceilings are covered with a textured coating, often called Artex, rather than paint. HSE lists textured decorative coatings among the places asbestos can be found in buildings built or refurbished before the year 2000 [S4]. HSE says not to try to repair or remove asbestos materials yourself without training for non-licensed asbestos work [S4].
Do not scrape, sand or steam a textured coating to get paint off it. Our guide to plastering over Artex and Artex removal cost guide explain the options. This page does not give any method for disturbing a textured coating.
What happens after the paint is off?
Once the wall is stripped, check the plaster. Old plaster can be cracked, hollow or crumbly underneath. Small defects can be filled. Larger areas may need patching or a new skim by a plasterer.
New or bare plaster usually needs a thinned first coat before normal emulsion. Our guide to painting new plaster covers that. If you are also taking off wallpaper, our wallpaper removal guide explains the steps.

Questions about removing paint from walls
Do I need to remove old paint before repainting?
Usually not. If the old paint is sound, it can be washed, lightly keyed and painted over. Strip only where it is flaking, peeling or bubbling, or where the new finish needs a bare surface.
Can I test old paint for lead myself?
GOV.UK says test kits sold on the internet are not accurate and may give a false answer, although they can be useful before starting renovation to see if lead paint exists. If you are unsure, treat old paint with caution or ask a decorator.
Is sanding paint off a wall a good idea?
Dry sanding makes a lot of dust, and with old paint that dust may contain lead. HSE lists wet abrasive paper among lower-dust methods for leaded paint. For large areas, ask a decorator what method they would use.
