⚡ At a Glance
- • Bond Strength: High-strength adhesive suitable for sealing felt laps and bonding chippings to final felt layers
- • Best for: Roofing professionals and DIYers needing durable felt repairs and lasting adhesion
- • Not ideal for: Enclosed, poorly ventilated interiors where solvent fumes present a concern
Solvent-based formulation bonds felt to metal, concrete, timber and asphalt. The cured film remains flexible with temperature changes and resists dilute acids, alkalis, water, alcohol and most salt solutions.
Secure seals for felt laps - With high-strength solvent-based formulation
Solvent-based adhesive cures to form a strong yet flexible film that adheres to both porous and non-porous substrates. The chemistry allows the film to harden and then soften as temperatures change without brittle failure.
Reliable seam sealing prevents water ingress and keeps felt edges bonded under foot traffic and changing weather conditions.
Versatile bonding across substrates - Thanks to compatibility with metal, concrete, timber and asphalt
Formulation is designed to bond to a wide range of roofing materials, creating mechanical and chemical adhesion where different substrates meet. Suitable for use where felt meets metal or masonry.
Handy for patching mixed-material roof areas and for sticking chippings to the final layer of felt during resurfacing.
Durable, weather-resistant finish - With a flexible film that resists common chemicals and moisture
The cured film offers resistance to dilute acids, alkalis, water, alcohol and most salt solutions, maintaining integrity when exposed to common environmental agents. Flexibility helps absorb thermal movement without losing adhesion.
Keeps repairs resilient through wet weather and temperature swings, reducing the need for frequent touch-ups.
