Energizer® BK

Specially formulated cold-applied waterproof coating improves the long-term performance of new and existing coal tar pitch and asphalt roofing systems.

The polymer-enhanced asphalt coal tar blend provides natural resistance to moisture, chemicals, UV and aging. The cold-applied nature of Energizer BK eliminates many of the harmful emissions of a conventional hot-applied coal tar system while providing the same performance benefits. Energizer BK is also fiber reinforced to provide superior sag resistance, increased tensile strength, excellent crack resistance and improved weathering resistance.
