Bostik Flashband Roof Primer S.V. for Flashing Tape, 500ml

The Bostik Flashband Primer S.V. is a solvent-borne bitumen solution specifically designed to prepare porous or dusty surfaces before the application of Bostik Flashband, particularly in damp or cold weather conditions. This fast-drying, cold weather formula makes it incredibly easy to apply when you need it most, ensuring reliable performance even in adverse environments.

By priming and sealing the surface, this black bitumen solution significantly improves the grab and adhesion of Flashband and other bitumen products. It is highly effective on porous, rough, dusty, or damp surfaces, creating an optimal base for a secure and lasting bond.

This versatile primer is ideal for treating a wide range of materials, including:

• Brickwork
• Cement renderings
• Roof tiles
• Concrete
• Mineralised felt
• Timber
• Metal

Supplied in a 500ml tub, the Bostik Flashband Primer is an essential preparation step to maximise the performance and longevity of your flashing tape applications. It is also suitable for use prior to applying other bitumen products where surface porosity or dust is a concern.
