Simple-to-use Shore Adhesive is a one-part contact glue for repair of Avon, Hyside, Riken, and other synthetic rubber inflatables. Toluol is the solvent used to clean and prepare the surface and to thin the glue. Apply Shore in two thin coats, letting the first dry before applying the second. Shore has a shelf-life of about 18 months, but to be sure you should replace your adhesive every year. Use these products in a ventilated area.
