Flashband Bostik Flashband Evo-Stik Flashband & Primer Grey 3.75 x 75mm is rated 3.7 out of 5 by 16.
Rated 5 out of 5 by from Been a year so far Applied this to edges of a flat roof to stop leaking and so far it has stayed in place and still looks tightly bonded to the surfaces. It comes with a small pot of primer which was more than enough and is important you use it. Will look to purchase this again for other ad-hoc repairs. It's not supposed to be a permanent fix, but so far so good.

Rated 5 out of 5 by from Good value with primer Great to have the primer included, and cheaper than buying separately. It is surely an essential for most surfaces, eg brick and cement. Primer dries quickly, Flashband easy to use.

Rated 5 out of 5 by from Does what it says on tin Excellent product, does just what it says on the tin. Good service and brilliant price.

Rated 5 out of 5 by from FLASH BAND-AID Using this on my workshop and the conservatory roof/wall seal. Sometimes I use a primer if I have some. What I always use is a decent powered hair-needs to be 1800W minimum I think. Hopefully this should give you a temperature of about 90-100C. (Heat guns tend to be too hot.) This activates the adhesive and you don't really need the primer. Even Bostik say it's better but not essential.

Rated 1 out of 5 by from Awful - doesn't stick at all Used to join a lean-to polycarbonate shed roof to the adjoining wall. I used this exactly as described, applied the primer to the brick first then rolled out the flash band and applied some pressure to stick it down, it just didn't stick! it didn't even feel sticky on your fingers when I unrolled it. Completely disappointed and now I need to try and find a solution to replace it which is more hassle.

Rated 5 out of 5 by from Great Product At A Great Price I had a look around for some Flashband to help seal my Aviary. I knew the size I wanted and all I needed to do was looked for it at the right price. Out of all the places I looked This seemed to be the same as everywhere else. Then I spotted that you actually get a small tin of primer with the flashband as well. Whixh for me is a win win. A Great Value Product And Does A Great Job as well. Thanks Screwfix. I Highly Recommend. *****

Rated 5 out of 5 by from Works even on a cold day. I had to fix 2 holes, the size of a new penny, in a lead gully between two adjoining slate roofs, in January, when it was cold but dry. Following careful preparation and priming I warmed the tape on a radiator then rolled it down. It stuck well, the edges appearing to be tightly down. I have only just done this so I cannot comment on the performance and reliability yet, however the tape feels and behaves like a good quality product.

Rated 4 out of 5 by from Great Product I like DIY products like this that give you all you need to get the job done easily and this Flashband containing the small can of primer is ideal. Drys quickly and fixes and seals easily, just follow the instructions and a waterproof job is done.
