198 Asphalt Roof Resaturant

KARNAK 198 Asphalt Roof Resaturant is a carefully prepared blend of selected asphalt, mineral fillers and selected penetrating oils. These penetrating oils soak into the existing roof mat to help rejuvenate the old asphalt. In addition, a thick layer of asphalt remains on the surface of the roof to protect it from the ultra-violet rays of the sun as well as serving as a binder for the replacement of the gravel or slag.

Preparation & Application

SURFACE PREPARATION:
Remove all loose gravel, dirt and dust from the roof by sweeping or power brooming. If existing gravel is to be reused, it must be washed free of silt. Repair all blisters, breaks or holes in the roof with KARNAK 19 Ultra Rubberized Flashing Cement and KARNAK 34 Asphalt Saturated Cotton Fabric, KARNAK 31 Fiber-Glass Membrane, or KARNAK 5540 Resat-Mat.

APPLICATION:
Brush: KARNAK 198 Asphalt Roof Resaturant is easily applied when poured directly from the container and spread with a thick fiber roof brush at the rate of 7 to 8 gallons per 100 sq. ft. After application of KARNAK 198 Asphalt Roof Resaturant is completed, gravel should be re-applied at the rate of 400 lbs. per 100 sq. ft. Spray: KARNAK 198 Asphalt Roof Resaturant is easily and efficiently applied on large areas with a standard mastic pump. The coating should be sprayed on in one coat at the rate of 7 to 8 gallons per 100 sq. ft. applied with a 50% overlap of the spray pattern so as to obtain a uniform and continuous film. After application of KARNAK 198 Asphalt Roof Resaturant is completed, gravel should be reapplied at the rate of 400 lbs. per 100 sq. ft.

COVERAGE RATE:
Apply at 7 to 8 gallons per 100 sq. ft.
