It says there is a 24 hour cure time, after only 6 hours it would not come off the test pieces, I recommend cleaning surfaces with Denatured Alcohol. Just as you would with solid-surface. We are very pleased to say the least, after watching that hack in those commercials I had doubts but no more. Review: Glue That Works - Our Grandkids love their Lily Pad to run, jump and swim on at the lake. After 4 years of wear and tear and MO winters it cracked about 54 inches. Since Lily Pads are over $500.00 we decided to try the Flex glue clear. We layed it out on the patio and applied the glue on one side, let it dry 24 hours then applied on the other side. We also applied the clear Flex Tape for extra hold. Good as new! The Grand kids are the true test and $500.00 or more is a true savings. ## Features - CAULKING GUN REQUIRED FOR THE 9 oz.
