Backer Board Joint Self-Adhesive Sealing Waterproofing Tape 100mm x 20m

Backer Board Joint Self-Adhesive Sealing Waterproofing Tape 100mm x 20m

A non-curing, butyl rubber-based tape designed as a self-adhesive sealant for construction joints. It combines high-density butyl rubber with specialized additives to deliver flexibility, strong adhesion and waterproofing without solvents or toxic emissions.

Its unique formulation ensures it remains pliable, adapting to substrate movements (e.g., thermal expansion, structural shifts) without cracking or losing bond strength.

Product features:
Instant Adhesion: Bonds strongly to wood, concrete, metals, plastics, and coated surfaces—no priming needed.
Lifetime Flexibility: Never cures; absorbs up to 3mm substrate movement to prevent joint cracks.
Waterproof & Weatherproof: Zero water permeability; resists UV, chemicals, and temperature extremes.
Easy Application: Peel-and-stick installation; cuts with scissors. Sets instantly under pressure.
Eco-Safe: Solvent-free, VOC-free.
