Whether air dry or heat cure, it usually takes 3-4 coats of putty to fill a void and level the surface plus a final thin texturizing coat.
Any holes, rips, or tears through the material must first be subpatched. Sometimes the edges marry together nicely, but usually some voids remain. These gaps are deeper and may require more putty than worn, scaly, or chafed areas that have not yet torn.
For voids larger than 2 in. wide, glue a top-patch of similar-grained leather or vinyl to your subpatch. This results in a more durable, flexible repair and uses less putty.
| Type of Damage | Total Area of Damage | Filler Needed |
|---|---|---|
| Chafed, scaly, cracked but no cuts or holes | one coat on 4 sq ft (or four coats on 1 sq ft) | 1 oz. |
| Chafed, scaly, cracked but no cuts or holes | one coat on 8 sq ft (or four coats on 2 sq ft) | 2 oz. |
| Holes or tears (requires a subpatch & more coats of filler) | 12 sq inches (1 in x 1 ft cut, for example) | 1 oz. |
| Holes or tears (requires a subpatch & more coats of filler) | 24 sq inches (two 1 in x 1 ft cuts, for example) | 2 oz. |
