Overview

Built to move. Built to last.

Polyurethane Sealant is a single-component, moisture-curing polyurethane sealant for sealing dynamic construction joints, expansion joints, and movement joints in concrete, masonry, and metal substrates. Cures by reaction with atmospheric humidity to form a tough, elastic seal with excellent adhesion.

The most widely used sealant across waterproofing, glazing, and façade contracts.

Key Features

  • Accommodates ±25% joint movement without failure
  • Excellent adhesion to concrete, masonry, metal, and timber
  • Paintable with most water-based and solvent-based paints
  • Tear and abrasion resistant
  • UV-stable variants available
  • ISO 11600 F-25LM classified
