A general purpose, waterproof coating for all common roofing surfaces including mastic asphalt, roofing felt, corrugated iron, fibre/cement, slates, lead, copper, tin and zinc. Excellent adhesion to damp surfaces, resistance to extremes of temperature and does not crack in the cold or flow in the sun. Recommended where the threat of frost or rain precludes the use of an emulsion. Can be over coated with a suitable decorative solar reflective paint to prolong the life of the coating.

Preparation
All surfaces must be structurally sound, clean, dry and free from surface contaminants such as grease, rust and dirt. If necessary, remove any organic growth i.e. moss or lichen, with a fungicidal wash. If the surface is still dusty after cleaning, or covered with weathered bitumen, prime with BITUMEN PRIMER and allow to dry.
