Artex Removal and Skim Coating: Asbestos Risk, Removal Methods and Getting a Flat Finish

Quick Answer: Artex applied before 1985 may contain chrysotile (white) asbestos at levels up to 3–4%; the only legally compliant approach before any sanding, scraping, or grinding is an asbestos survey or bulk sample analysis. If ACM (asbestos-containing material) is confirmed, a licensed contractor or trained competent person must manage removal. Artex applied post-2000 is asbestos-free; for any Artex, the most practical modern approach is to leave it in place and skim coat over it.

Summary

Artex — the trade name for a textured coating that was standard on UK ceilings from the 1960s through to the 1990s — sits on perhaps 40% of all UK pre-1990 housing stock. Decorators and plasterers encounter it on virtually every period property job, and the client question is almost always the same: "Can we get rid of it and have a flat ceiling?"

The answer has two parts. First, is the Artex safe to disturb? Pre-1985 Artex contained chrysotile asbestos; disturbing it by dry sanding, grinding, or scraping creates airborne fibres that are a serious health risk. Second, even when safe, full removal of Artex is not always the most practical approach — skim coating over it is faster, less disruptive, and produces a flat finish that most clients cannot distinguish from a full replacement.

This article covers asbestos assessment, the legal position for removal, the removal methods available, and the skim coating technique for covering Artex without removing it.

Artex Age Asbestos Likely? Recommended Approach Legal Requirement
Pre-1985 Yes — test first Sample test; skim over if possible CAR 2012 compliance; NNLW or licensed removal
1985–2000 Possibly Sample test before disturbing CAR 2012 compliance if ACM confirmed
Post-2000 No Safe to remove or skim No asbestos requirement
Unknown age Unknown Sample test first Treat as pre-1985 until proven otherwise

Detailed Guidance

Asbestos Assessment: The First Step, Always

Before any decorator quotes for Artex removal, they must establish whether asbestos is present or not. Quoting without this assessment creates a liability — if the client proceeds on a quote that assumed Artex was asbestos-free and it isn't, the cost of proper removal can be 5–10× the original quote.

Visual assessment: You cannot confirm the presence or absence of asbestos visually. The fibres are invisible to the naked eye and the texture appearance is not diagnostic. Any claim that "it's just plaster, you can tell by looking" is incorrect.

Bulk sample testing:

This is the correct approach for confirmed identification:

  1. Wear a P3 half-mask respirator, disposable gloves, and eye protection
  2. Wet the area with water and a small amount of washing-up liquid
  3. Using a sharp knife, cut and collect a 1 cm × 1 cm square of the textured material
  4. Seal in a zip-lock bag, then seal in a second zip-lock bag
  5. Send to a UKAS-accredited laboratory (list available via HSE)
  6. Results returned in 2–5 working days

If the result is positive (asbestos present): treat as an asbestos-containing material. Follow CAR 2012 requirements. Skim-coating without removal is the preferred approach for most domestic situations — it encapsulates the Artex and avoids disturbing it.

If the result is negative (no asbestos): the material can be removed or worked on without asbestos-specific controls.

Removal Methods (Where Confirmed Asbestos-Free or Post-2000)

Steam stripping and wet scraping:

A steam stripper (wall-paper steamer) applied to Artex for 30–60 seconds per section softens the texture and the adhesion to the ceiling substrate. While still wet and hot, scrape off the textured layer with a broad scraper (150–200 mm). The steam also keeps any fibres damp and reduces airborne dust even on asbestos-free Artex.

This method works well on Artex that was applied to plasterboard or a skim coat over plasterboard. It is less effective on Artex applied directly to lath-and-plaster ceilings — the lath-and-plaster is porous and the steam causes the plaster keys to soften and can damage the ceiling.

Chemical softening:

Commercial Artex remover products (Zinsser DIF, Ronseal Artex Remover) are applied generously to the ceiling surface and left for 20–30 minutes. They contain surfactants that break down the adhesion of the Artex layer. Scrape off while wet. Multiple applications may be required for thick Artex.

Sanding (post-2000 or confirmed asbestos-free only):

Dry sanding Artex is fast but generates large amounts of dust. Use a dustless sanding system (vacuum-coupled random orbital sander) with P3 dust mask as minimum respiratory protection. Never sand pre-1985 Artex without asbestos-negative test results.

Skim Coating Over Artex: The Most Practical Approach

For most domestic ceiling jobs, skim coating over Artex is faster, cheaper, and less disruptive than removal. It is suitable for any Artex that is structurally sound (not loose, not crumbling, not water damaged).

Preparation:

  1. Check for any loose sections by pressing gently with a wide scraper — any hollow sound or flexing indicates a loose section that must be removed or fixed before skimming. If more than 20% of the ceiling is loose, assess whether full removal is more economical.
  2. Apply bonding agent — Gyproc Bond It, Thistle Bond It, or SBR diluted 3:1 with water, brushed generously across the entire Artex surface. Allow to go tacky (typically 20–45 minutes depending on temperature). The bonding agent prevents the dry, absorbent Artex from sucking moisture out of the finish plaster too quickly.

Skim application sequence:

The skim coat must bridge the texture of the Artex and build up to a flat surface. This requires multiple passes rather than trying to fill the texture in a single heavy coat.

First coat — bridging:

Second coat — levelling:

Third coat — finishing:

Total plaster depth over Artex is typically 5–8 mm depending on texture depth. On deep Artex (fan and swirl patterns), allow up to 10 mm.

Common failure — rushing the process: Attempting to build up 8 mm in a single coat causes slumping and cracking. Allow each coat to firm up before applying the next. The total process should take 4–6 hours for an average bedroom ceiling.

Frequently Asked Questions

Can I charge more for Artex jobs if there might be asbestos?

Yes, and you should. The additional cost covers: sample testing (your time and lab cost), appropriate PPE (P3 mask, disposable coveralls, gloves), wet working method on any removal, correct hazardous waste disposal, and the liability of working with an ACM. A typical domestic Artex ceiling with asbestos testing and wet removal costs 40–70% more than an equivalent post-2000 textured ceiling. Make the additional costs transparent in your quote.

My client wants to know if the skim will crack over time. How honest should I be?

The bonding agent and correct skim technique make cracking unlikely in a well-built property. Cracking risks increase where: the substrate has structural movement (old lath-and-plaster that flexes); the Artex was not fully bonded and moves slightly; there is recurring damp from above. In period properties with lath-and-plaster ceilings, advise the client that some hairline cracking over time is possible — this is inherent in the substrate, not the skim technique. Offer crack-filling as part of annual redecoration at no extra charge to manage expectations.

Is there a way to test for asbestos without taking a sample?

No reliable method exists for in-situ testing without sampling. Portable XRF devices can indicate mineral content and are sometimes used in survey work, but PLM analysis (bulk sampling) at a UKAS lab is the definitive method accepted by HSE. Any contractor claiming they can identify asbestos Artex visually is incorrect and legally exposed if their identification is wrong.
