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. "

" have used nearly 30 tubes in the past few weeks
Easy to use, excellent seal if used correctly.
Check the date on the tubes sometimes they can be old.

Check the date!
6 Jul 2012
By Devonguy

" I sealed round an exterior window frame with this, went away on a fortnight's holiday and came back to find it hadn't cured at all and was still very tacky. I then belatedly checked the "use by" date to find that Screwfix had sold me a tube which was a full 2 years out of date. The local branch replaced it without question but of course the very messy job of removing the defective sealant and replacing it was down to me. The replacement is fine and cured virtually immediately (so my rating relates to the 2nd tube, not the first) but I noticed that of the four tubes then in stock at the local branch one was a year out of date and the other 3 were just about to go out of date. So the moral is CHECK THE DATE. "

" 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 "
