Does Flex Glue harden?

Flex Glue is soft when first applied, but it will harden over time. It can be tooled or repositioned within 10 minutes of initial application and will be dry to the touch in 1 hour. In 12-24 hours, Flex Glue dries into a strong, flexible rubber. It will not shrink, crack, or peel during the curing process and will reach maximum strength after 7 days.
