⚡ At a Glance
- • Weatherproofing: Fibre-reinforced solvent-based bitumen forms a durable, waterproof barrier
- • Best for: Resealing non-plastic guttering, structural steelwork and roof repairs
- • Not ideal for: Plastic guttering and applications specified as unsuitable for solvent-based bitumen
Solvent-based brushable bitumen coating with added fibres for extra strength. Dries quickly and will accept a second coat after 24 hours.
Fast Recoating – Thanks to quick drying formula
A solvent-based bitumen formulation dries rapidly on exposed roofing surfaces, allowing a second coat to be applied after 24 hours. Brushable consistency encourages even laying without specialist equipment.
Work can progress quickly with less downtime between coats, useful for finishing sections before bad weather arrives.
Long-lasting Protection – With fibre-reinforced finish
Fibres are incorporated into the solvent-based bitumen to reinforce the cured film, reducing the likelihood of cracking and improving mechanical resilience. The resulting membrane acts as a continuous barrier against water and vapour ingress.
Repairs and treated areas stay sealed for longer, cutting the need for frequent touch-ups.
Versatile Application – With compatibility across multiple substrates
Formulated for adhesion to a wide range of non-plastic surfaces including asphalt, felt, concrete decks, metal sheeting and tiles. Brush application makes it suitable for irregular profiles and joints.
One product can cover many common roofing tasks, simplifying material choices for mixed-surface roofs.
