Rated 5 out of 5 by from Easiest I've ever used Bought this to seal a window frame inside the house. It went on more easily than any other I have used in the past 20 years, and with less mess. Definitely worth the extra cost!

Rated 5 out of 5 by from Good stuff I bought this to seal around the exterior of upvc windows. Does the job perfectly. It’s more like a frame sealer than a silicone. Creates a great seal and won’t shrink and pull away like a normal silicone sealant. Worth paying the extra.

Rated 1 out of 5 by from Discoloured after a year. Unfortunately, the sealant turned cream-coloured after a year. Does not look good. It was used on an internal window frame/sill that wasn't in direct sunlight.

Rated 5 out of 5 by from Scotty6404 Only just used product so can't comment on the longevity of the product but it goes on easily and leaves a lovely finish.

Rated 5 out of 5 by from silicone 796 Easy to use, Good price, Creates and smooth finish. Does what it says on the tube.

Rated 1 out of 5 by from Awful product Used much cheaper silicones before from Screwfix without a problem with smoothing. This product sticks to your fingers or smoothing tool like glue and getting a smooth finish is impossible. Expiry date of product just 3 months away which I thought was very unusual but assured no problem. Having to re-do the whole job.
