Rated 5 out of 5 by from DOES THE JOB I used this on my old pre fab concrete garage to reduce the draughts where the panels met it came out of the tube really easy but did not slump so I could do a seven foot by half inch run in one go easily and the silicone adhered well to concrete and when I checked it the next day it was set nicely but still soft to touch so had the flexibility that I needed in the garage and as a bonus it was on offer

I need to seal around a window in current rainy weather. Can this be applied in wet conditions or will it affect its performance.
