ABSTRACT:
Base vinyl material is readied for repair by preparing the edges of a hole to get a clean sharp periphery, and by cleaning the base material. A substantially non-heat shrinkable, precured, vinyl-welding compound having high tensile strength and low fusion point is laid in the hole so that it abuts against the periphery of the hole and then is fused to the base material by heat. The upper exposed surface of the repair is smoothed to present a continuous, uninterrupted surface with the base material. A hard and flexible graining tool is obtained from an impression of the base material. The graining tool is applied to the upper surface of the welding compound after it and the surrounding base material have been heated sufficiently to receive a grain impression.
