Why i chose this, because it works. If you read or research the manufactures preparations prior to applying, you will find that "It Works". Really, the temperature range is between ( -80° ~ 350° ) , wow ! Only thing I did not care for was the smell at first. The off gas is bad. Always use your ppe respirator. In a few hours it dissipates and the smell is much weaker.

FLEX SEAL SAVES THE DAY

We got hit with Hurricane Ida in Northeast Queens NY.. We never get hit..This is the first time this section was drowned!!! I truly feel for all those that were hit Katrina....so our basement was completely flooded...I decided to give Flex Seal a try last month...Yes...Last month...waiting for water to dry up and disinfect and clean...plus waiting for the Flex Seal to arrive...Well...Happy to report...very happy with the outcome...it has rained a lot here and thank goodness...not a drop has come through the walls or ground..My husband and dad covered the wall and ground with Flex Seal..last week..we put peel and stick tile...I'M SO GLAD I WATCHED ALL VIDEO'S AND TOLD MY HUSBAND AND DAD THAT WE ARE USING THIS!! MY DAD HAS USED THIS PRODUCT BEFORE.
