Advanced Hybrid Technology offers excellent flexibility, UV resistance and wet surface adhesion.
Bonds strongly to most building materials without primer*.
Creates a waterproof, elastic seal that stops leaks and damage.
Paintable with most water-based paints for a neat finish.
Non-sag formula works well on vertical and horizontal joints up to 30mm wide.
