This large Vinyl Pool Repair Kit features 4 oz. of adhesive and 500″ squared of vinyl to help patch and repair your liner. Prior to patching ensure all surfaces are clean. Cut round circles out of the patch. For inflatables and light gauge vinyls, apply adhesive to patch sparingly and press tightly to surface to be repaired. Allow to dry for 24 hours. A face mask or underwater goggles should always be used when going underwater to make repairs. For deep underwater repairs, cut round corners on patch. Apply adhesive to patch and fold patch over upon itself. When you reach the damaged area under water unfold patch and apply immediately to liner, squeezing out all water bubbles. Do not disturb patch for at least 48 hours. Allow 4-7 days for full cure.
