APPLICATION


The temperature of karnak #79AF Wood Block Mastic when applied should be above 70°F.

Low areas should be filled with concrete patching mix. Let dry thoroughly after cleaning or patching. Dusty or very porous surfaces should be primed with Karnak #108 Asphalt Primer at the rate of 1/2 to 1 gallon per 100 sq. ft.. Karnak #108 Asphalt Primer must be fully cured, (dry to the touch), before application of Karnak #79AF Wood Block Mastic.
