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.

Abstract: The edge of a hole in base vinyl material is cut clean and sharp and the material bounding the hole cleaned. A liquid vinyl compound is layered into the hole with each layer cured after it is applied. Only the last layer is pigmented to match the color of the base material. The exposed surface of the final layer is blended with the base material to present a continuous, uninterrupted surface. A hard, flexible and clear graining tool obtained from an impression of the base material is applied to the upper surface of the welding compound and indexed with the grained pattern of the vinyl base material after the cured welding compound and surrounding base material have been heated sufficiently to receive the grain impression.
