Flex Glue is a multipurpose adhesive that can bond a variety of different surfaces together, including metal, wood, foam, rubber, tile, ceramic, marble, porcelain, glass, granite, brick, concrete, stucco, plaster, stone, masonry, drywall, sheet rock, fiberglass, some plastics and vinyls, composites, PVC, EPS, EPDM roofs, and more. Customers report success with a variety of applications, including securing fire brick for a wood stove, holding ceramic tile soap dishes on painted sheetrock walls, and patching vinyl pool liner material underwater. The glue is designed to withstand temperatures ranging from -40°F to 200°F. However, the company advises against using Flex Glue on gas, oil tanks or radiator since it can't withstand extreme heat or pressure.
Some customers had issues with getting the product out of the tube, but rolling the tube up from the bottom and using a skewer to unclog it can help. Although the product may be hard to get out, it is still considered an excellent product by many customers. However, it is essential to test the glue on a small area before application since it may resist adhesion to some plastics.
