Rated 1 out of 5 by from Absolutely useless This product was purchased to bridge a small gap between lead flashing and painted render. It would not adhere even slightly to either surface.

Rated 5 out of 5 by from Good gap sealant Used to seal slight gap between the base of a timber garage sitting flush on DPC and concrete base. Needed to stop moisture ingress due to capillary action so the cement floor was thoroughly dry ready for floor paint. Had to wait for dry weather but the Flashband bonded well to the wood and appears to have stuck to the cement without using any extra sealant. Did the job and very pleased with the result. Useful tip: A wooden wallpaper seam roller is a great help to fix the Flashband in place.
