Adomast Adocoat Bitumen Primer – 5 Litre

Adomast Adocoat Bitumen Primer is a low viscosity, high penetration, cold-applied bituminous solution designed to prime and seal porous roof surfaces prior to the application of bituminous materials.

Adomast Adocoat Bitumen Primer seals porous substrates and promotes the adhesion of bituminous waterproofing systems and sheet coverings.

It may be applied to a range of surfaces, including:

• concrete
• asbestos cement
• metals (mild steel, zinc, lead)
• slate
• lightweight concrete screeds

Application:

Method of application: Adocoat Bitumen Primer should be applied by brush ensuring an even coat with no pooling, or applied evenly by airless spray.

Instructions: Care needs to be taken over preparation of surfaces before application. All surfaces must be free from oil, dirt, dust and loose debris. On metal surfaces all loose rust should be removed using a wire brush and where advanced signs of corrosion are evident the area be treated with a rust inhibitor. Surfaces should be dry for best results, although Bitumen Primer will adhere to damp but not wet surfaces. Bitumen Primer is resistant to rainfall within 20-30 minutes of application.

Cleaning Tools: Tools may be cleaned with white spirit. Minor spillages should be wiped off surfaces before the compound has set. Major spillages should be mopped up immediately with an inert, absorbent material, such as sand, and disposed of in accordance with regulations.

Coverage:

The coverage per litre is dependent on the porosity of the surface:

• Metal surfaces: 6-12m2 per litre
• Concrete: 6-8m2 per litre
• Lightweight concrete screeds and asbestos cement: 3.5-5m2 per litre
