Urethane Brush-Grade 522 is a high-solids, single-component, moisture-curing polyurethane elastomeric coating. Specifically formulated with a thicker consistency than Urethane 520, Urethane Brush-Grade 522 is a mastic designed to waterproof and protect large gaps and problem areas.

  • Extremely durable and resistant to dirt pick-up
  • Superior adhesive and cohesive strength
  • Excellent elongation and tensile strength
  • Superior UV protection and reflectivity
  • Reduces daily expansion and contraction (thermal cycling) of roofing substrate

Urethane Brush-Grade 522 was developed from Aromatic Urethane 520 as a waterproofing mastic to use with Urethane 520 and other coatings. With excellent adhesive qualities, Urethane Brush-Grade 522 can be used to restore and protect most conventional commercial and industrial roofing substrates.
