What are sprayed asbestos coatings (limpet)?

Asbestos sprayed directly onto steel and concrete for fire protection and insulation — typically a rough, fibrous grey layer on beams, columns and soffits of 1950s–70s buildings. It can be up to 85% asbestos, the highest-risk material there is.

Why are sprayed coatings treated as the most dangerous ACM?

Because they’re soft, high in fibre content — often crocidolite or amosite — and shed with the lightest contact. Even minor disturbance releases serious fibre levels, so everything about their removal is maximum-control: licensed teams, full enclosures, injection and wet methods.

Can sprayed coatings be encapsulated instead of removed?

Sometimes — sound coatings in undisturbed voids can be encapsulated and managed, avoiding a major removal. But where refurbishment or demolition will disturb them, removal under full licensed conditions is the only route.

Where sprayed asbestos coatings are found

Typically found in structural steel beams, columns, ceiling soffits and plant room walls, most commonly in industrial units, multi-storey car parks, high-rise blocks and large public buildings. Leave any material you suspect may contain asbestos undisturbed. Get advice before drilling, sanding, scraping or carrying out other work that could damage it. A photograph can help us offer initial guidance, but it cannot confirm asbestos. We will explain whether sampling or a survey is needed.

How sprayed coating removal works

This is licensed work. Every job starts with sampling and a written quotation; straightforward enquiries can usually be quoted within 24 hours. Removal is carried out with the controls the law requires for this material, waste leaves site with consignment notes, and the area is handed back with the right certification for your records, whether that's a homeowner's document pack or a four-stage clearance certificate.

What sprayed coating removal costs

Typical UK guide range: £200 to £400+ per m², including disposal and paperwork. Access, quantity and condition move the number, our cost guide and calculator covers the detail, and once we quote, the price is fixed. Figures are industry guide rates, not Innov8 Group prices, we're typically cheaper. Contact us for an official quotation.

Why sprayed coatings are the highest-risk asbestos material

Sprayed asbestos — often called limpet — was applied wet to structural steel, concrete soffits and plant rooms from the 1950s into the early 1970s as fire protection and insulation. It could be up to 85% asbestos, frequently the amphibole types (amosite and crocidolite) that carry the highest health risk, and it was left with a soft, open texture that sheds fibres at the lightest contact. That combination puts sprayed coatings at the very top of the risk scale: where AIB releases fibres when worked on, limpet can release them simply from vibration, water damage or age. All work on sprayed coatings is licensed asbestos removal — there is no DIY route and no non-licensed shortcut.

Where limpet turns up

The classic locations are the steel frames of 1950s–70s industrial and commercial buildings: beams and columns above suspended ceilings, the undersides of concrete floors in office blocks and car parks, plant rooms, boiler houses and lift motor rooms. It was also sprayed onto the soffits of system-built schools and flats. Because it hides above ceilings and behind risers, it is regularly discovered mid-refurbishment — which is exactly the wrong moment. If your building dates from this era, a refurbishment and demolition survey before any intrusive work is the only safe way to find it first.

How licensed removal works

Sprayed coating removal is notified to the HSE at least 14 days before work starts. The area is sealed in a full negative-pressure enclosure with airlocks, the coating is wetted and removed under controlled conditions by operatives in RPE, and every stage is air-monitored. The enclosure only comes down after an independent analyst passes the area through the four-stage clearance and issues the certificate of reoccupation. Waste travels as hazardous waste with consignment notes. It is the most controlled procedure in asbestos work, because the material demands it — our licensed removal teams carry it out routinely on industrial and commercial sites.

What it costs, and what decides the price

Licensed enclosure work is priced per project rather than per square metre: enclosure size, access, the amount of steel to strip, plant-room congestion and air-testing requirements all move the number. Encapsulation — sealing sound coating in place under a managed regime — can be a legitimate interim option where removal is not yet practical; our encapsulation service covers when that makes sense. For budgeting, our cost guide explains how licensed work is quoted, and every quotation we issue is fixed in writing.

Where we remove sprayed coatings

We deliver licensed sprayed-coating removal across the UK, most frequently on industrial and commercial buildings in Manchester, Liverpool and Leeds, with locations in Manchester, Carlisle and London providing coverage across the UK.

Testing before assumptions

Not every rough coating on steel is limpet — vermiculite and cementitious fire sprays look similar from floor level — and not every limpet coating is obvious, because many were later overpainted or boxed in. The only reliable answer is analysis: our sampling and testing service takes controlled samples and returns UKAS-accredited results, typically within 48 hours, which either releases your programme or tells you exactly what you are dealing with before a single trade is booked. Never let anyone scrape a bit off to have a look — that is precisely the disturbance the material punishes.
