Rated 3 out of 5 by from Great product unfair price The product was easy to use and the finish was great. I needed 150mm wide flashband but I only needed 3 meters length, so purchased this. However 10 meters of 150mm wide was only 50p more money. This dosen't seem right.

Rated 5 out of 5 by from Surprisingly good Apprehensive about the purchase to start with however I was surprised at how easy the product was to use, even for someone who is not a regular DIY’er.

Rated 4 out of 5 by from Works well for me Used this Bostik flashband with primer a couple of times now to seal between a lean to shed and brick wall. The primer adhered well to the brickwork and the band stuck very firmly to the primer. The only issue was that the flashband couldn’t be pressed down to fill the corrugations in the roof, so I squirted a little expanding foam up between the flashband and the roof sheets to seal the gap.

Rated 5 out of 5 by from Flash (tape) bang wallop Bought this item to repair a leak in a joint along the edge of my lean to. Painted on the primer left it for 10 minutes then applied the flashing tape. So far so good. Not a drop of water in sight and it had rained quite heavy at times. We’ll pleased.

Internal underside of rafter

Can I use this on the underside of my roof rafter in my loft to seal an internal leak in my loft (from rainwater)?
Asked by: BM10
The Bostik Flashband Primer Grey 3.75m x 150mm product is a self-adhesive flashing tape with a grey lacquer finish on top, and a resin modified bitumen on the underside. The product can be used for general roof maintenance and repair in suitable applications and it will bond to materials such as roof felt, wood, metal, concrete and rigid PVC / UPVC among others. The product is specified for exterior applications only where it will be waterproof from rainwater from above when situated ( for example ) on an exterior roof, however it is not recommended to be applied internally where water ingress will be from behind and be against the bond line, also, it may be difficult to apply and bond overhead.

G4 Damp Seal Adherence

Will the flashing adhere to G4 Damp Seal on wood and does it need to be applied to the wood when the G4 is tacky or dry?
Asked by: FrontsideProperty
The Bostik Flashband & Primer Grey 3.75m x 150mm product is a self-adhesive flashing tape with a grey lacquer finish on top, and a resin modified bitumen on the underside. The product can be used for general roof maintenance and repair in suitable applications and it will bond to materials such as roof felt, wood, metal, concrete and rigid PVC / UPVC among others. However it is not designed or intended to be applied to a product such as the G4 Damp Seal product, and because Flashband is bitumen based, there may well be compatibility issues with the Damp Seal product, and so such a use of the Flashband product in this case is not recommended.

Minimum/ maximum time for primer to dry?

With the water based primer supplied, what is the minimum time that should be allowed between applying the primer and applying the tape? I know the maximum time is 24 hrs, but what would happen if a longer time elapsed, say 28 hrs?
Asked by: OldFlitwickian
Bostik Flashband Primer Emulsion for Roofs dries by loss of water. In warm, dry conditions the primer can dry in as little as 20 minutes. In cold, damp conditions, below 80% humidity it may take 2 hours. If left longer than 24 hours, you may be required to reapply the primer again and allow to dry.

Can you form this into a right angle prior to placement

Asked by: Deadley1
The Bostik Flashband ( & Primer ) Grey can be applied to various materials including wood, metal, concrete, brickwork and stonework among others. When applying the product, the surfaces need to be mainly flat and smooth, however whilst the product can be applied at certain angles, it will be more difficult to apply at a right angle. In such a situation, it is best to use a triangular fillet such as by applying a cement mortar or fixing a triangular piece of wood in the corner so that two 45 ° angles are produced rather than having one 90 ° angle.
