Rated 5 out of 5 by best sealant ever. always good services at screwfix, very helpful and always have plenty of time to help. they also recommend what other customers have enjoyed. 5 Dec 2014
Rated 4 out of 5 by Sealant I have used this sealant before and thought it was pretty good. The tube that I bought from Screwfix jammed, ie the inner tube which should slide wouldn't move. Took the tube back to Screwfix and they replaced without any quibble. Not used the replacement yet but if there is a problem I will repost. 27 Nov 2014

100% silicone sealant

I need to purchase a silicone sealant that is free of anti-mildew chemicals etc. as I'm building a glass aquarium as standard silicone sealants can be toxic to fish over time.
