DAP 18810 is a one-part, moisture-curing, elastomeric polyurethane sealant designed for heavy-duty sealing applications in residential and commercial settings. This commercial-grade sealant is formulated to create a long-lasting, durable, waterproof seal when filling exterior gaps, joints, and cracks. It bonds to most substrates and maintains exceptional flexibility, making it ideal for use in any climate where water resistance is critical.

The permanent flexibility of this sealant allows it to withstand joint movement of up to ±35%, ensuring the seal remains intact even as building materials expand and contract with temperature changes. Its exceptional cut and tear resistance means it can handle foot and vehicle traffic without cracking or peeling. The paintable surface dries to a clean, professional appearance.

  • Moisture-Curing Formula: One-part application that cures in 4 to 7 days without requiring a catalyst or second component.
  • Waterproof and Flexible: Remains permanently flexible to accommodate ±35% joint movement while providing a complete waterproof barrier against moisture infiltration.
  • Heavy-Duty Performance: Built for residential and commercial work with excellent adhesion to most substrates.
  • Cut and Tear Resistant: Withstands foot and vehicle traffic without cracking or peeling, ensuring lasting performance in high-traffic areas.
  • Paintable: The cured surface accepts paint for a seamless, professional finish that matches surrounding surfaces.
