ACRYSHIELD A420 is a multi-purpose, acrylic, elastomeric coating for use over a variety of substrates including asphalt and metal roofing. A420 has unique “bleed blocking” properties that make it particularly suited for coating over asphalt surfaces. A420 far exceeds the ASTM D6083 requirements for critical properties such as tensile strength, elongation, wet adhesion and weatherability.

BENEFITS: APPROVALS:
  • Seamless Waterproofing
  • Fully-Adhered Installation
  • Asphalt Bleed Blocking
  • acrylic Durability
  • Energy Savings
  • Prolonged Roof Life
  • Reduced Life Cycle Costs
  • Renewable

As an ENERGY STAR® Partner -Product in white, meets the ENERGY STAR® guidelines for energy efficiency.
