4010 Vapor Barrier Coating is a thick film asphalt mastic reinforced with
fibrous mineral fillers that provide a vapour resistant protective coating for
thermal insulating materials, and for chemical protection and damp-proofing of
masonry and metal surfaces. The incorporation of fibrous mineral fillers
reinforces the film strength, durability and impermeability, and enhances the
excellent corrosion and chemical resistance of a thick film, asphalt-based
vapour barrier coating.
Insul-Mastic 4010 is recommended for cold
application on the exposed surfaces of thermal insulating materials, such as
fibreglass, mineral wool and cellular glass, to prevent the penetration of
moisture vapour, acid, alkali and salt fumes.
It is also a superior
product for damp-proofing and waterproofing masonry and concrete surfaces below
and above grade, and protection of metal surfaces exposed to highly corrosive
