Features: 1. Made with waterproof material and designed to work under air pressure. 2. Suitable for repairing cuts and holes on inflatable boats, rafts, kayaks, canoes, above-ground swimming pools, air or water beds, mattresses, inflatable sofas, lounges, and water toys. Instructions: 1. Deflate the product to ensure the repair area is as flat as possible. 2. Clean and dry the repair area thoroughly. For better adhesion on flocked surfaces, apply a small amount of glue to the area and gently rub to remove the flocked texture, exposing a smooth surface. 3. Apply only enough liquid cement to wet the back of the patch. Avoid using excess cement, as it may prevent a proper seal. 4. Press the patch firmly onto the repair area and hold in place temporarily. 5. If repairing an inflatable item, do not reinflate for at least 12 hours.
