Rated 5 out of 5 by from Flashy Band Used the flashband primer and then applied the flashband. Relatively easy to put on the flashband although if you need to take it off to readjust position, it can take off the primaer as well. The product was available for pickup from the nominated Screwfix shop the day after ordering. No problems apart from parking being a bit tight at the store.

Rated 5 out of 5 by from Bostik Flashband Grey Bought this to ensure that a hole where I removed an aerial pole did not allow in water. Very easy to apply and the finish looks great. I believe at this point that it will do the job for a long time to come.

Rated 5 out of 5 by from Great stuff Excellent product. Used to seal a leak on a flat roof that just kept coming back. Use of a primmer and clean dry area for application is a must. I don’t know quite how to say this but here goes. I applied it on a very warm day so cut and laid it out, sun warmed it up and it got very sticky while applying (nightmare). If you can, keep it cool until your ready to stick it down and then work quickly before it warms up and sticks to everything! Once applied let it warm up and then apply even pressure to ensure full adhesion. P.S white spirit works wonders at cleaning of the tar from hands or tools.
