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
Rated 5 out of 5 by best in bathrooms/kitchens This product is excellent, both in clear and white. Not only does it seal but, you can smooth it with absolute precision, and it just looks fantastic afterward, when dry! 8 Mar 2011

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.
