Bostik Bituminous Mastic is a multi-purpose, fibre-reinforced bituminous sealant designed for waterproofing, stopping, bedding, pointing, and sealing applications. Supplied in a convenient 300g cartridge for use with a standard sealant gun, it is formulated to deliver immediate resistance to rainfall. This black sealant dries to form a flexible, waterproof barrier that remains soft and pliable over a long period, accommodating natural structural movement and offering high resistance to continuous weathering.
It is compatible with a broad range of building materials and can be applied directly to mastic asphalt, roofing felt, corrugated iron, cast iron, fibre cement, slates, lead, copper, zinc, concrete, and timber. This versatility makes it an effective solution for repairing cracks, filling gaps, and sealing joints on flat and pitched roofs.
Application is straightforward using a standard mastic gun, which allows for precise, targeted extrusion directly into the repair area. The cartridge format eliminates the need for separate troweling tools for small repairs, making it well-suited for both targeted patching and longer sealing runs. Once applied, the sealant provides a durable fill that resists environmental exposure while maintaining its flexibility over time.
- Fibre-reinforced bituminous sealant designed for waterproofing and sealing tasks.
- Delivers immediate resistance to rainfall upon application to the repair area.
- Adheres to asphalt, roofing felt, metal, concrete, slates, and timber substrates.
- Dries to a flexible finish that remains soft and pliable to accommodate movement.
- Supplied in a 300g cartridge for direct application via a standard sealant gun.
