Rated 5 out of 5 by Dow 791 excellent I've always used DC silicone, this product is another example why. Not worth saving a couple of quid on cheaper stuff if you value what you do. 13 Jul 2016

Rated 5 out of 5 by Dow Corning W/Proof Sealant Very easy to apply; dried quickly with a good finish. Used it to stop water coming through a crack in concrete floor. Had a heavy downpour last night and no signs of water seepage so far. 13 Jun 2015
Rated 4 out of 5 by Quality silicone Good quality Low Modulus silicone that performs well. The Low Modulus is always more expensive but has greater flexibility so that's what I needed 18 Mar 2015
