Rated 4 out of 5 by lead sealant I've used the product to seal overlapping sheets above a bay window the sealant appears to have bonded adequately and will remain flexible to allow for the expansion and contraction 14 Apr 2016
Rated 5 out of 5 by Lead flashing sealant I have used this product previously, to replace mortar where lead flashing enters the joint between two courses of bricks. It provides a clean, tidy finish which will, undoubtedly, outlast a mortar repair. The previous work is still as good as new and the latest purchase is to undertake the same repair on my neighbour's house. Highly recommended and cannot be faulted 31 Dec 2015
Rated 5 out of 5 by Just The Job Was looking for a suitable sealant to seal the edge of my flashing tape which was sealing the plastic sheeting on my newly erected lean to on the side of my house. Obviously had a couple of pin holes where the tape was not 100% stuck on the wall , evident by the rain weeps coming down on the inside wall.. The recent rains showed them up. After looking through Screwfix catalogue, I decided to give this product a try. Today it is really peeing down and not a sign of any leakage. Found it easy to apply, I used a trowel and my finger but used a fine water spray bottle to apply a light amount of water before smoothing out. Excellent job I must say. Well done Screwfix 17 Nov 2015
Rated 5 out of 5 by High quality flashing sealant I have used this sealant previously. It is easy to apply and is a great value sealant for sealing virtually all types of flashing materials to other building components. It looks good and adheres well to form a watertight seal. The colour is primarily intended for sealing lead flashing to brick but its neutral grey colour goes well with virtually any material and it can be overpainted if required. I have always found that the best way to achieve a smoothly contoured finished surface is to use your forefinger and saliva (spit!) making sure that you wipe your finger clean each time you need more saliva! 6 Nov 2015

I have used various products over the years, but none remain stuck down more than a few short weeks/months when used to try and repair/fill cracks that have developed in lead guttering, as a consequence I was wondering how good this product would be in the circumstances described.

This product does have good adhesive qualities and should be suitable for the application that you are hoping to use it for. just ensure that the surface is prepared in line with the manufactures instructions.
