Flashband Bostik Flashband Flashband Grey 10 x 225mm is rated 4.6 out of 5 by 19.
Rated 2 out of 5 by from not sticking well I had to repair a patch in my flat roof. I used this to seal the edges around the patch. IT was basically bringing from the old felt to the plywood. I had primed the whole area including the overlap but for some reason it didn't want to stick. I pressed it down fully for a few mins rolling hard with a seam roller then it just pulled off with little effort. I have re-stuck and will check it again but docent look good. I think I will over paint the whole area with a liquid rubber solution.

Rated 5 out of 5 by from Perfect low cost solution Had to repair (a cowboys attempt at) flashing on a conservatory roof. Flash band provided a cheaper alternative to traditional flashing. Went on well, just remember to use primer.

Rated 5 out of 5 by from Good stuff Sticks instantly bear in mind porous materials need priming first 500ml tin go's a long way

Rated 5 out of 5 by from FLASHBAND - Flashing Roll I have used the narrower Flashband before successfully and this was the first purchase and use of the 220mm wide Flashband. It is important to prepare the surfaces first using Flashband Primer. Again a simply process of painting areas and leaving to dry and so then ensuring a good bond with FlashBand. Flashband is easy to apply and it is a good idea to use a decorators roller to ensure firm and tight adhesion and no leaks. A great and reliable product the does what it says and last a long time in use

Rated 5 out of 5 by from Great alternative to lead Needed to seal brick panels between timbers on an old black and white house and this lead alternative has enabled a much cheaper job with same weatherproofing results
