Rated 5 out of 5 by from Worth a little extra Without doubt the best product on the market, especially if used in conjunction with the primer. Never had bad service from Screwfix, friendly,helpful staff as always.

Rated 4 out of 5 by from Flashing Review Excellent product - I had some tricky tiles to apply the flashing to along with a straight edge - with the assistance of a Stanley knife and a small bit of heat from a heat gun the flashing moulded and stuck to all surfaces really well

Rated 5 out of 5 by from Waynew Although manufacturer says this is not for felt. I bought the primer and this and used it to patch a hole in roofing felt. I’m happy with this temp fix, until I can get felt replaced probably. Ordered and collected next day from Gloucester branch.

Rated 5 out of 5 by from Superb flashing I recently purchased this product to protect exterior ply that I used to box in some pipework. It adheres superbly to wood and stipled render which I was very surprised at and is very easy to fix and cut. I highly recommend this product for all types of flashing work.

Rated 5 out of 5 by from flashband bostik 10 x150mm This product is brill it has sorted out my leak on my flat roof it has really lived up to its name, this is the item you should consider if you have a leak

Rated 5 out of 5 by from Worked really well! I used this to seal about 2 metres of my workshop roof. The plastic roof sheet had failed at the edge and water had begun to run down the inside of the wall. I bridged the gap from the roof in to the gutter and it has worked really well. No water coming in at all since! It was so easy to use and shape around some awkward angles. Roll the band out, peel the backing off and you're good to go. I used a cheap heat gun to melt the band which worked really well - no need for any primer. The best tip I have is to use a mini paint roller (without the sleeve) to press the band down and get a nice even contact.

Rated 5 out of 5 by from Best product by far Used most makes and the original is the best it sticks well and is extremely durable. More expensive but if you want it to last it's worth the extra
