Green Glue Longevity

There was a question raised about the life span of Green Glue. So, just in case anyone else is curious, I recieved this reply from the company: Thanks for the interest in Green Glue. The acrylic make-up of Green Glue is quite widely known for its stability. Indeed, acrylic is specified in industries where long term durability and stability are needed. We have been involved with accelerated aging tests, and believe that Green Glue will outlast 50 year caulk. Thanks again! Ted White :)
