Sprayed Asbestos Coating & Limpet Removal UK
Specialist licensed removal of sprayed asbestos coatings and Limpet asbestos from structural steel, concrete beams, columns, ceilings, soffits, roofs and other building surfaces. Sprayed asbestos is one of the highest-risk asbestos-containing materials, so ASM assesses every project individually before the licensed removal scope and price are confirmed.
What is sprayed asbestos coating?
Sprayed asbestos coatings were applied to structural steel, reinforced concrete and other building surfaces to provide fire protection, thermal insulation, acoustic insulation and anti-condensation properties.
They are sometimes referred to as Limpet asbestos, although sprayed asbestos coatings were installed using several products and methods.
HSE describes sprayed coatings as one of the most dangerous asbestos-containing materials because they can contain very high proportions of asbestos and break up extremely easily.
Even minor disturbance can release large quantities of fibres. HSE therefore states that all work with sprayed asbestos coatings is high risk and must be undertaken by an HSE-licensed contractor.
Licensed removal is delivered within F&I Group through Flowing Construction Services under asbestos-removal licence 202505985.
How much does sprayed asbestos coating removal cost?
ASM does not publish a generic £/m² price for sprayed asbestos removal because surface area alone does not provide enough information to determine the scope of a licensed removal project.
Each sprayed-coating project is individually inspected and assessed before a final fixed quotation is provided.
The quantity of sprayed asbestos is important, but enclosure complexity, access, coating thickness, substrate, contamination and clearance requirements can have an equal or greater effect on cost.
Arrange an AssessmentWhy a simple square-metre price can be misleading
A 100m² coating applied to accessible steel beams inside an empty industrial unit can represent a very different project from the same area:
- above a suspended ceiling;
- at high level;
- within an occupied building;
- inside a multi-storey car park;
- around complex structural steelwork;
- with heavy overspray;
- with delaminated debris;
- across several separate enclosures.
The final price therefore follows a detailed site-specific assessment.
Where is sprayed asbestos found?
Sprayed asbestos was particularly useful where fire protection or insulation had to follow irregular structural surfaces.
Common locations include:
- structural steel beams;
- steel columns;
- reinforced concrete beams;
- concrete columns;
- undersides of floors;
- undersides of roofs;
- warehouses;
- factories;
- multi-storey car parks;
- high-rise buildings;
- theatres and auditoria;
- studios;
- industrial buildings;
- plant areas.
HSE also notes that overspray and splash-back were common during installation, so asbestos may be present outside the obvious coated surface.
Large sprayed-coating areas can extend through an entire structure
Sprayed asbestos was frequently applied as fire protection to the structural frame of a building.
This means the asbestos may continue across:
- multiple beams;
- columns;
- cross-members;
- floor soffits;
- roof structures;
- service zones;
- concealed areas above suspended ceilings.
A survey needs to establish the actual extent before the removal contractor can develop an appropriate enclosure and programme.

ASM uses the site assessment to establish the true licensed-removal scope before the final quotation is prepared.
Is sprayed asbestos coating removal licensed work?
Yes. HSE specifically identifies work with sprayed asbestos coatings as high-risk work requiring an HSE-licensed asbestos contractor.
| Activity | Risk | ASM route |
|---|---|---|
| Sprayed coating removal | Highly friable asbestos material with significant potential fibre release. | Licensed asbestos-removal project. |
| Damaged sprayed coating | Material may already be releasing asbestos debris and fibres. | Licensed assessment including contamination extent. |
| Overspray / splash-back | Asbestos may exist beyond the primary coated structure. | Included in survey and removal-scope assessment. |
| Sprayed coating debris | Loose friable asbestos contamination can be present on horizontal surfaces. | Licensed contamination/removal route. |
| Coating on structural fire protection | Removal may affect the building's required fire-protection performance. | Asbestos removal coordinated with appropriate follow-on fire-protection assessment and reinstatement. |
Do not confuse sprayed asbestos coating with decorative Artex
Textured decorative coatings such as Artex are a different ACM category and can often be lower-risk. Sprayed asbestos insulation and fireproofing coatings are much more friable and HSE states that all work on them is high risk and must be undertaken by a licensed contractor.
For decorative textured coating, see Asbestos Artex Removal UK .
How sprayed asbestos coating removal is controlled
Every sprayed-coating project requires a site-specific risk assessment and detailed plan of work. The outline below describes the general professional process rather than providing removal instructions.
Confirm the sprayed coating, extent, thickness, condition, substrate, overspray, debris, access and wider construction requirements.
Develop the project-specific licensed plan of work and establish the required enclosure, negative pressure, access, DCU, transit and waste arrangements.
The coating is removed using the licensed contractor's selected controlled method with suitable fibre-suppression measures, RPE/PPE and ongoing supervision.
The substrate, structure and enclosure are thoroughly cleaned before progressing through the applicable independent analytical clearance and handover procedure.
Wet-removal techniques can significantly affect fibre control
Because sprayed asbestos coating can release very high concentrations of fibres when disturbed, the removal method must reduce fibre release at source as far as reasonably practicable.
Suitable wet-removal techniques may form part of the licensed contractor's method depending on the coating, substrate, condition and project.
HSE's recent research into licensed asbestos removal found wet techniques being used across licensed-removal sites and emphasised selecting a wetting approach appropriate to the material being removed.
The methodology must be specific to the actual sprayed coating
Coating thickness, porosity, sealants, paint, substrate and deterioration can all influence how fibre-suppression measures work. The licensed contractor therefore establishes the detailed method through the risk assessment and plan of work rather than applying one generic removal technique to every building.
Overspray can make the actual asbestos area larger than expected
HSE specifically notes that the historic application process could create overspray or splash-back around the main treated surface.
Licensed sprayed-asbestos removal requires advance planning
Planned licensable asbestos work must normally be notified to the appropriate enforcing authority at least 14 days before the work starts.
A realistic project programme should therefore allow for:
- survey review;
- site assessment;
- extent confirmation;
- quotation and instruction;
- detailed plan of work;
- licensed-work notification;
- access/scaffold installation;
- enclosure construction;
- licensed asbestos removal;
- detailed cleaning;
- four-stage clearance;
- fire-protection reinstatement where required;
- reoccupation or handover.
Four-stage clearance following sprayed asbestos removal
Licensed removal within a controlled enclosure requires thorough contractor cleaning before the area is offered for the applicable independent four-stage clearance process.
The analyst reviews the site condition, enclosure, scope and supporting documentation.
Structural steel, concrete, joints, services, ledges and other surfaces are checked for residual asbestos and debris.
Air sampling is undertaken in accordance with the applicable HSG248 clearance requirements.
Following satisfactory enclosure dismantling, the final assessment is completed before successful reoccupation documentation is issued.
Removal can create a fire-protection reinstatement requirement
Sprayed asbestos was often installed specifically to provide fire protection to structural steel or concrete.
Removing the asbestos does not remove the underlying need for the structure to achieve the required fire-resistance performance.
Depending on the building and project, follow-on works may therefore involve replacement protection such as an appropriately designed:
- board fire-protection system;
- sprayed non-asbestos fireproofing system;
- intumescent system;
- encasement;
- other specified passive-fire protection.
Do not remove structural fire protection without considering the replacement
The asbestos-removal scope and the building's required fire strategy should be coordinated so that removing the ACM does not leave the structural frame without its required level of protection.
Licensed removal within the wider building project
Sprayed asbestos removal is often part of a larger industrial refurbishment, structural upgrade, demolition or fire-protection project.
