One-component coating based on acrylic resins in aqueous dispersion for permanent encapsulation of type A (visible outside), B (visible inside) and C (not visible, before confinement) of asbestos sheets , certified in accordance with the DM August 20, 1999. ELASTOCAP-ABC is characterized by high flexibility, resistance to yellowing, adhesion and creates a waterproof and crack-resistant membrane.

ELASTOCAP-ABC is a product certified as being suitable for inertising Type A, Type B and Type C asbestos cement products.
A minimum 0.60 kilograms of ELASTOCAP-ABC per square metre of surface is to be applied in two coats.
For visible or invisible permanent encapsulation of flat and corrugated roofing sheets and coverings containing asbestos fibres subject to degradation.
If the surface is intact and only partially affected by the presence of mould and vegetation, it must be adequately suctioned using specific equipment, wet cleaned and treated with biocidal products to prevent dispersing the fibres into the environment and to permit the reclamation of the water used for washing. If the surface is particularly damaged or covered with mould and vegetation, it is necessary to inform the competent Local Health Authority by submitting an appropriate intervention plan. Cleaning in any case must be carried out with low-pressure water that is to be recovered in special containers for the subsequent disposal of the sediments. Any detached parts and waste are to be properly disposed of as asbestos waste. Always operate in compliance with current regulations on asbestos reclamation, occupational safety and environmental pollution. Apply a coat of BOND PLUS for the impregnation of the substrate and the incorporation of asbestos fibres, preventing any dispersions in the environment. The use of primer also favours the adhesion of the encapsulating coating, to be applied after the primer has dried (about 30–40 minutes depending on the temperature). BOND PLUS can be applied by spray (airless) with a consumption of about 100-300 grams/m2, depending on the degree of absorption of the substrate.
Spray ELASTOCAP-ABC onto clean and dry surfaces (at a pressure of 200–210 bar) once the BOND PLUS is completely dry. The product can be diluted with 15% water to facilitate application.
For TYPE A and B ENCAPSULATION COATINGS, application requires a minimum of two coats in different contrasting colours, waiting approximately 12–24 hours before the application of the next layer, in accordance with environmental conditions.
A single coat of ELASTOCAP-ABC is sufficient for NON-VISIBLE TYPE C COATINGS. The average and total minimum thicknesses required by current standards vary depending on the type of coating (see the table). The appearance of the underlying layer of cladding caused by environmental conditions and wear indicates a need to work on the surface once more to restore the encapsulant coating.
