DRYPROOF ASPHALT COATING is roofing in plastic form and is fortified with polyester fiber
Although it spreads freely with a roof brush, DRYPROOF ASPHALT COATING is thick in consistency. It stays where it is brushed and does not run through roof cracks and joints in hot weather. After drying, DRYPROOF ASPHALT COATING loses only 32% of its weight by evaporation – much less than the average “liquid” roof coating.
To prepare a roof properly for the use of DRYPROOF ASPHALT COATING, begin by cleaning the surface thoroughly of all dust, mud, slag, paint or other loose particles. Do not apply when temperature is below 8o C.
Nail down all loose flashings.
Patch open breaks or torn roofing by brushing DRYPROOF ASPHALT COATING over the area, then nailing either asphalt felt, burlap or roll roofing over this.
To apply DRYPROOF ASPHALT COATING, use a regular fibre,long handle roof brush. Regular paint brushes are not satisfactory. Brush on DRYPROOF ASPHALT COATING thoroughly working into all joints and patches on roof, to be well sealed and coated.
Coat entire area uniformly with DRYPROOF ASPHALT COATING at the following rate: Metal, asphalt roll roofing and built-up roofs – 45 square feet per gallon. Slag roofs, 30 square feet per gallon. Roofs with a badly worn felt base may use somewhat more than the foregoing quantities due to absorption.
Never thin ASPHALT COATING or its durability will be destroyed.
