Bostik Idenden ET-150 is a professional-grade asbestos encapsulation paint developed to safely seal and stabilise asbestos-containing materials. It dries to a flexible, durable and water-resistant film that prevents fibre release while extending the life of the substrate. Tested to BS 476 Parts 6 and 7, ET-150 achieves a Class 0 fire rating, delivering proven flame spread resistance for refurbishment and compliance projects.
This low-VOC, water-based coating is suitable for both internal and external applications and can be applied by spray, brush or roller. Acting as a vapour barrier, it resists liquid water while allowing controlled moisture vapour transmission to avoid trapped condensation. Available in white, black and grey 10L buckets, ET-150 is designed for a two-coat system with contrasting colours to guarantee full coverage.
Bostik Idenden ET-150 provides a reliable, compliant and easy-to-use solution for contractors, surveyors and building owners who require long-term asbestos protection and peace of mind.

Shelf Life: Up to 18 months in original, unopened containers when stored correctly between +5°C and +25°C, protected from frost and direct sunlight.
Clean & Stable Substrate: All surfaces must be clean, dry and free from dust, grease, oil, loose particles, or contaminants that could impair adhesion.
Asbestos Surfaces: Only sound asbestos materials should be encapsulated. Preparation and handling must follow current local authority and national asbestos regulations.
Priming: Apply Bostik PVA primer to asbestos surfaces in accordance with the product data sheet before coating with ET-150.
External Conditions: Do not apply in poor drying conditions or when rainfall is imminent. External areas should be tented or protected until the coating has cured.
Mechanical Damage Areas: Joints, corners, or areas subject to impact may require embedding reinforcement (such as scrim canvas or glass cloth) into the first wet coat.
Surface Profile: Ensure the substrate is shaped to prevent standing water. A minimum slope of 15° is recommended for horizontal surfaces before applying the coating.
Not for Unsound Asbestos: Only stable, intact asbestos-containing materials should be encapsulated. Damaged or friable asbestos must be handled in line with regulations and by licensed contractors.
External Use Precautions: While suitable for external applications, the coating must be protected during curing to prevent rain or standing water from damaging the film.
No Standing Water: The product is not designed for ponding or permanently submerged areas. Surfaces must be sloped to shed water.
Not for Floors: ET-150 is not suitable for use as a floor coating or in areas subject to heavy foot traffic.
