Used for both commercial and domestic applications, and provides excellent adhesion to most exterior substrates. It has excellent weathering characteristics, including resistance to ozone, UV radiation and temperature extremes.

Review: Used this to seal the walls of a concrete panel garage to the concrete base. Was easy to apply and filled the gaps. Quite hard to push into the gaps and then smooth as its very sticky, needs a wet finger to help a bit As proof of use - in the very heavy rain in the UK late September I had standing water outside the garage but the inside was dry so a success - would use again
Review: Dow, always good and never had a problem with any of their sealers and silicones. I won’t buy any other brand.
