Coal Tar Sealer

Ready-to-Use/ Federal Grade/ Sand Mix

Meets or Exceeds the RP 355E Federal Specification

Composition
Coal Tar Sealer consists of highly refined clay slurries that are milled with coal tar pitch and selected emulsifying agents. This exclusive milling process is far superior to batch methods as it completely homogenized the finished products, eliminating sag flow, blistering and color variation.

Physical Data
Coal tar Sealer shields asphalt surfaces from the damaging elements of weather and protects against the harmful effects of chemicals and petroleum products. Coal Tar Sealer exceeds Federal Specification R-P355e and ASTM Specifications D-3320. Federal Grade requires 15% to 25% dilution with water, depending on climate and weather conditions.

Application
Coal Tar Sealer may be applied by brush, squeegee, or mechanical equipment. The pavement must be sound, as well as being free of dirt, dust, clay, sand, vegetation, and all other loose materials. Particular attention must be given to the treatment of petroleum residues. All holes, crumbled areas, and cracks should be repaired before sealing. Ambient temperatures should be at least 50 degrees Fahrenheit and rising for application. Latex modifier is recommended at 1% to 2% by volume. Silica 70 mesh silica sand is recommended at 1-4 lbs. per gallon to insure skid resistance.

Yield
45-60 square feet per gallon based on the recommended two coat application. The exact coverage will depend on the application method and the existing asphalt surface condition.

Drying Time
The first coat will dry to the touch in a few hours. The second coat may be applied when the first coat is dry to the touch. The final coat will dry overnight under ideal conditions (70 degrees Fahrenheit 50% humidity).

Clean-Up
Tools may be cleaned with water before material use. Once dry, solvent such as xylene or tolulene must be used. For hands and skin, use a waterless hand cleaner.

Availability
Five (5) gallon pails, fifty-five (55) gallon drums, and bulk quantities.

Cautions
Coal Tar Sealer must be kept from freezing. Allow new surfaces or patches to cure 30 days before sealing. If the sealed lot is to be striped, a latex traffic paint is recommended since oil base paints will bleed and discolor. Do not apply if rain is imminent.
