## Description

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: Did what I hoped - 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: Top notch - Dow, always good and never had a problem with any of their sealers and silicones. I won’t buy any other brand.
