Max-A-Seal DP

Non-fibered emulsion coating & air/vapor barrier system

Max-A-Seal DP® is a Non-Fibered Emulsion Coating designed according to ASTM D1227, Type III specification. This asphalt emulsion coating is formulated to provide excellent damp-proofing and vapor barrier properties, making it suitable for various applications. It is available in fibered, non-fibered, and trowel-grade versions to suit different application needs.

  • Suitable as a protective coating for asphalt, metal, wood, and masonry surfaces.
  • Zero VOC content, making it environmentally friendly and compliant with ICF forms.
  • 50% solids content, ensuring a robust application.
  • Resists water penetration while allowing moisture vapor to escape.
