Rated 4 out of 5 by from Around the Door/Window I went with the 791 Dow Corning option - primarily for its expansion/flexibility qualities. Need to go around the window frame and doorway. This is always needed when the weather changes.

Rated 5 out of 5 by from 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.

Rated 4 out of 5 by from 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

Could you advise what the curing time is for this silicone?

Asked by: reppppppppppppp
Higher temperatures and higher humidity (within reason) increase the cure rate of most commonly available silicones including Dow Corning 791. In normal conditions, Dow Corning should be tack free within the hour and cure at a rate of approximately 2/3 mm per 24 hours.
