Asbestos Encapsulation

Asbestos Encapsulation Paints & Sealers – Safe, Compliant Coatings for Managing Asbestos-Containing Materials (ACMs)

Asbestos encapsulation products are designed to safely manage asbestos-containing materials (ACMs) by sealing them in place, preventing the release of harmful fibres into the air. Instead of removing asbestos – which can be hazardous, time-consuming, and expensive – encapsulation creates a protective film over the surface. This method is widely used in industrial, commercial, and public buildings where asbestos remains undisturbed but requires long-term control. These coatings are typically applied to pipe lagging, sprayed coatings, soffits, ceiling boards, and other surfaces where asbestos paint was originally used. They are suitable for both interior and exterior use and can be found in schools, factories, heritage properties, and storage facilities. The encapsulation process preserves the original material while reducing risk, making it a practical solution when removal is not required by law.

Available products include flexible, high-build coatings, sealers, and reinforced finishes that resist cracking, weathering, and chemical exposure. Application is by brush, roller, or spray, depending on the system chosen. Correct surface preparation is essential. Most systems require cleaning and stabilisation before application. In some cases, a compatible primer may be necessary to promote adhesion and long-term performance. For exterior applications, especially corrugated sheets or industrial roofing, asbestos roof paint provides a durable finish that helps prevent fibre release. All encapsulation work should be carried out in line with HSE guidance, and may require a licensed contractor depending on the substrate and condition of the material. To ensure product suitability and legal compliance, contact the technical support team for specific advice on preparation, application, and site conditions.

Asbestos Encapsulation FAQs

What is asbestos encapsulation, and how does it differ from removal?

Asbestos encapsulation involves coating or sealing asbestos-containing materials (ACMs) to prevent the release of harmful fibres. It does not remove the asbestos but instead isolates it with a protective barrier. Removal involves physically extracting the material, which is more disruptive, expensive, and often requires licensed contractors and waste disposal.

When is encapsulation a suitable option?

Encapsulation is typically used when ACMs are in good condition and unlikely to be disturbed. It is suitable in buildings where full removal would pose unnecessary risk, cost, or structural compromise. A risk assessment should always be completed first.

Can I carry out asbestos encapsulation myself?

In most cases, only trained and competent individuals should apply encapsulation systems. Depending on the product, the substrate, and the condition of the asbestos, some projects may legally require licensed contractors. Always follow the HSE guidance and consult the Control of Asbestos Regulations.

What surfaces and materials can be encapsulated?

Encapsulation coatings are commonly used on asbestos cement sheets, pipe insulation, sprayed coatings, lagging, and boards. The surface must be dry, stable, and free from loose or friable material. Some porous substrates may require priming first.

Can I paint over encapsulated surfaces?

Yes, provided the topcoat is compatible with the encapsulation system and does not compromise its performance. Contact technical support before overcoating to ensure the full system remains effective.
