Bostik Flashband Grey 10m x 100mm (57969)

Bostik Flashband Self Adhesive Flashing Tape for Roofs is a self-adhesive sealing bitumen strip which bonds instantly to provide a permanent watertight seal. Flashband bonds to most building materials including brick, masonry, slates, concrete roof tiles, wood, metal, concrete, terracotta tiles, glass, roofing felt, and rigid plastics.

The Bostik Flashband Grey product is a self-adhesive flashing tape with a grey lacquer finish on top, and a resin modified bitumen on the underside. The product can be used for general roof maintenance and repair in suitable applications and it will bond to materials such as roof felt, wood, metal, concrete and rigid PVC / UPVC among others. Normally once applied, it is left as the final finish, however it could be painted if desired, but there is no specific data or experience of applying any particular masonry paint, or the Dulux Weathershield paint to it as such. Consequently, it would be recommended to first do a test with the required paint on a small cut off piece of Flashband to ascertain that successful results are achieved before proceeding further. N.B. whilst grey lacquer finish is generally over paintable, there may be a little staining at the bitumen edge of the product after painting.

Bostik Flashband can be used on both new and old roofing felt. For improved adhesion on porous, rough, dusty surfaces, apply Bostik Flashband Primer Emulsion or Bostik Flashband Primer SV. Surfaces such as mineralised felt or textured brick may require two coats of primer.
