Rated 5 out of 5 by from Shed fix I've used this to cover a join where I have connected two sheds. Comes with the primer but I didn't need it in the end. Plenty left over and seems like it'll do the job. Time will tell with the British weather

Application Temperature

If the weather is cold , can you warm the band in an oven , and to what temperature ?
Asked by: DRaC
Application temperature: +5°C to +30°C. NB in cold weather (below +15°C) application may be easier by warming the surfaces and storing Bostik Flashband Self Adhesive Flashing Tape for Roofs in a warm place prior to use. I would not recommend warming the product in an over before use.

I have bitumen sheets on a lean too roof that is joining onto a brick wall and want to use this as a flashing to stop the water running of the wall into the lean too. As the roofing is undulating will this be a problem for the tape

and is it useable with the bitumen roofing sheets?
Asked by: Slatz76
The Bostik Flashband & Primer Grey 3.75m x 75 mm is self adhesive flashing tape with a grey lacquer finish on top and a resin modified bitumen on the underside. It will bond to various materials including roof felt. concrete, wood, smooth brick, UPVC, rigid PVC, bitumen and metalwork among others. For porous materials such as brick, concrete and wood the Flashband Primmer needs to be applied first and allowed to dry before application of the Flashband itself. ( for non-porous materials, the Flashband Primer is not required ). In general, the product is best used on smooth, flat surfaces and so if it the material is corrugated or undulating then it will be difficult to fit it into the undulations although the product can be cut and be overlapped and it will stick to itself. However depending on the amount and angle of the undulations as well as the overall length of the requirement, this may not be practical.

Use next to twin wall flue pipe for stove?

How heat resistant is this? Is it rated to be used next to twin wall stove pipe flue?
Asked by: R77777
Bostik Flashband Self Adhesive Flashing Tape for Roofs is a self-adhesive sealing bitumen strip which bonds instantly to provide a permanent watertight seal. Once applied the product has a temperature resistance between -10°C to +100°C. We would not recommend its application since the flue pipe will likely have higher temperatures.

Flashing for lean to shed

I am building a lean to shed against the brick side wall of the house. I would like to seal the join between the two over a felted shed roof. Will this serve as an alternative to replace lead flashing or is it a temporary repair only?
Asked by: SteveOtheshed
The Bostik Flashband & Primer Grey is a self adhesive flashing strip in the form of a resin modified bitumen on the underside and a grey lacquer finish on the topside. The product can be applied between roof felt and brickwork in general, but both materials will require priming with the Flashband Primer, a tin of which is in the middle of the roll. Once applied correctly the product is detailed to last for around 15 years, although potentially it could last for many years after that, so if it is used for repair ( in suitable applications ), the repair will be more of a permanent nature than temporary.

Can this be used on pvc guttering to seal joints?

Asked by: Leemma
I have used it for this purpose and it works well. Heat gun or hairdryer helps the seal and so far so good
