PACKAGING:
 
"A" and "B" components are packaged in equal volumes in 55 gallon drums, 15 gallon barrels, or 5 gallon pails. Shelf life is 12 months in unopened containers stored indoors. For small jobs apply PERCOL Asphalt Welder from 21 or 53 ounce cartridge kits with hand operated dispensing guns.

 INSTRUCTIONS:
Read Material Safety Data and the Installation Instructions before using product. PERCOL Asphalt Welder
performs well in temperature extremes. For best performance, install PERCOL Asphalt Welder at 10 degrees F. to 100 degrees F. ambient temperature and 50-75 degrees F. material temperature. Do not apply during rain or on wet surfaces.

BULK APPLICATION EQUIPMENT:
PERCOL dual proportioning system transfers, meters, mixes and applies PERCOL Asphalt Welder. "A" and "B" components are transferred from drums, through the proportioning pumps, (1:1 ratio) to the dispensing gun. Material is mixed at the gun, then dispensed into repairs.
