Rated 5 out of 5 by from Great value and use Used this to cover the decking frame. Great value and easy to use and cut. Very sticky so be careful when placing it down on its side!

Rated 1 out of 5 by from Wished I had read the reviews Bought to seal some loose flashing on my roof. Read the description and thought - self adhesive, can be used on brick etc - just what I need. Sadly, wouldn't stick to anything. I normally read reviews before purchasing but the overall star rating on Screwfix seemed very positive so didn't bother on this occasion and unfortunately - paid the price. Wasted my money.

Will masonry paint, such as Dulux Weathershield, stick to Flashband without cracking, crazing, or sloughing off?

Asked by: Stilldoingitmyself
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.
