Bostik Flashband 150mm x 10m is rated 4.7 out of 5 by 86.
Rated 4 out of 5 by from Trial fitting Only done a trial one metre length onto roofing felt, so far so good as its rained every day since i done it.

Rated 5 out of 5 by from Ideal for many jobs I know it says use primer and apply without heat but I've always used it with a heat gun or a blowtorch with gentle heat, it sticks better and is easier to fold into corners, just apply enough heat to soften the bitumen. I've used it for flashing a car port, covering tops of timber on a pergola, and repairs to leaky guttering. There's not much choice out there, and Bostik is a reputable brand.

Rated 5 out of 5 by from Easy to use! Wider than others that are commonly available, sticky without being impossible to reposition, substantial enough for the job but still flexible enough to tease into the exact position you need and into contours and corners etc. Pleased.

Rated 4 out of 5 by from Great product! I bought this flashband to try making a temporary repair to the felt roof on my summer house until I could do a re-felting job later in the year. I used the flashband along the overlaps and nails of the felt. Being a novice there were a couple of things that nearly caught me out! 1. The backing paper is pretty flimsy so I had to lift the flashband slightly to ensure all the backing paper had been removed. 2, The first rain after using the flashband there were still a couple fo drips into the summerhouse. I found a small 4 inch roller in my wife's crafting materials and ran it along the edges of the flashband with as much force as I could. Pleased to say that this has fixed the leaks and it should, hopefully, keep the summerhouse dry until the summer. Did the job I bought it for but may not have been the right stuff!!! Easy to cut and fit and made for quite a neat looking finish.

Rated 4 out of 5 by from Does the job! Used the primer before the Flashband and it staying firm on the wall and has stopped any leaks, looks good as well

Rated 5 out of 5 by from Fantastic Product Great example of a roll of flashband to use to do a temporary repair or depnding on what your putting it on, a more permanent fix. Good price. A word of warning, needs a bitumen primer applied before hand to make sure it sticks well.
