198AF Asphalt Roof Resaturants
Karnak #198AF 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.
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.
