ABSTRACT:
A vinyl repair compound and two step vinyl repair method provide an exceptionally strong and long wearing repair. The repair compound includes vinyl resins, a solvent, a plasticizer and silica filler, has a paste-like consistency and air dries. The repair process entails the following: trimming away the damaged material, placing backing material behind the damaged area if necessary, filling the repair area flush with the surface of the surrounding material with the repair compound and allowing it to air dry. Due to shrinkage of the compound as it dries, a depression is formed which is then filled with a conventional heat curable plastisol vinyl repair compound. If necessary, smooth or grained release paper is placed over the repair area, heat is applied to cure the plastisol compound and the repair is allowed to cool.
