Energizer BK

  • Long-Lasting Waterproofing
  • Strong & Flexible

Energizer BK is a fluid-applied product designed to waterproof various roof membrane surfaces. The polymer-enhanced asphalt/coal tar blend naturally resists moisture, chemicals, UV, and aging. This cold-applied waterproof system improves the long-term performance of existing coal tar pitch and asphalt roofing systems. It is formulated with a select blend of asphalt, refined coal tar pitch, aromatic solvents, and thermoplastic polymers. Energizer BK provides seamless, elastomeric surfacing for aged gravel, smooth, or mineral-modified roofing systems. Energizer BK also provides waterproofing protection over asphalt BUR or gravel-surfaced coal tar BUR.
