GRANVILLE GV0374 Silicone Sealant, 40 g, Clear

Used to seal a condensate leak on my combi boiler. Worked well.

Could have been easier to use. Difficult to squeezeMaybe it was just me.

Used to seal leak in car windscreen. Had no problems applying it as others seem to have done.

Finally got round to using it, only to find that the nozzle attachment doesn't stay on, so whenever the tube is squeezed the silicone would pop the nozzle off making it unusable. It made messy work, but the silicon itself works great for the job.

Good value, dedicated product from a reputable brand, for dealing with windscreen leaks. Used to fill gaps around the front windscreen gasket at top corners, easy to use. Results still awaited, hopefully correct leak source has been found. Granville also make power steering leak repair product, which works very well!

This is a very good sealant for filling gaps in metal, wood etc to fix leaks. It is a glue as well, though i myself have only used it to fill gaps rather than to stick things together. I have had problems in the past with the item drying up prematurely. I would never advise anyone to use the pointed top to pierce the tube as this tends to weaken and potentially damage the top letting air in.Apart from this an excellent product.

Very useful

Bought to reattach a rubber seal on car taillamp. After piercing the supplied tube of sealant and squeezing the tube, nothing came out until more than half the tube was squeezed. The small amount of content that did come out of the tube was not very sticky at all, nor was it strong and flexible when dry. More like transparent play-dough. Totally useless!
