Rated 4 out of 5 by from Flexible friend Used this to seal a plastic drain cover from leaves. Even though the cover was screwed tight to the wall they were still getting in. After placing a good bead round the unit and smoothing off with my finger it worked well. I also bought some screw top nozzles as I knew that I would not use all the tube. So hopefully if I need to use it again a year or so down the line the unit will still be usable. Screwfix staff A1 as usual.

Rated 5 out of 5 by from flexible weatherproof sealant I used this over a year ago to fix a leaking gutter and on a roof. Has remained flexible with no problems.

Rated 4 out of 5 by from Perfect match Laying black drainage channels before the winter rains and sections needed to be joined using a silicone sealant. This black silicone sealant is a perfect match on colour and seals well. Slightly more runny than some sealants but this helps it to flow into the joints to make a better seal.

Rated 5 out of 5 by from Black and sticky... I needed to seal a cable entry hole into a black sided portacabin. This did the job perfectly. The silicone is sticky and doesn’t move easily, unlike normal silicone sealants. Cleaning up is easy enough, and for me one tube of this will last ages (or until it naturally cures!)
