Rated 5 out of 5 by from Great Product first time I have had to try a product like this and was suitably impressed. Stopped the connections leaking which PTFE tape failed to do. Would recommend product.

Rated 3 out of 5 by from No nonsense leak sealant Doesn't seal external leaks. Looks like it is only for fittings. Don't know why it is called external.

Rated 1 out of 5 by from Doesn't stop leaks This isn't a great product. Had a leaking radiator tail, and this doesn't stick the the radiator enamel very well and thus didn't stop the leak. Removed the dried silicone to try again, and the whole tube had gone off in 3 hours despite me putting the lid back on.. Pity, because normally no nonsense stuff is great. You're better off buying a tube of normal sealant!

Rated 1 out of 5 by from Nothing more than silicone The product is simply a small tube of silicone sealant and should be advertised as such, no better no worse but don't expect much from it

Suitable for wooden summerhouse?

We have a wooden summerhouse (8'x8') that despite all attempts we cannot make watertight. Would this product work for that? Would we be able to spray/apply it over all of the external walls, corners etc to stop water ingress? Is this better than "No Nonsense Water Repellent Seal Clear 5Ltr" or would that be a better product for us to use? If we used it would we still be able to apply wood-stain?

Sealing doors

There is a leak on one of my UPVC doors. I intend to spray the outside with this, to see if it will stop water coming in. Will this work?
Asked by: JohnnyDP
This product is not a spray; its intended use is as a plumbing product to seal leaks in pipe work. It's unlikely to work for your intended use.

Can you use it on a wet surface?

I need to perform and emergency repair on a flat roof. Given the rain we have had recently it is unlikely that I will be able to wait until the weather clears. Can this stuff be ap;plied to a wet surface and does it have to be dry to cure?
Asked by: B0M0A0K
This product should be applied to a dry surface however once applied wetness to the external sealant will actually speed the cure.
