While shellac is not usually the finish paint choice, it is often thought of as the best paint primer available. It has properties that oil and water based paints can't match, and provides a more dependable seal than most other primers are able to provide.
Shellac finishes should be kept away from water, as they will become dull or even have a white residue appear when exposed to moisture. Should your shellac finish develop water spots, repair is relatively simple. Use straight alcohol on a pad and remove the shellac from the offending area.Then pad or brush on a series of coats of shellac and rub it out until the finish is even. Should a surface scratch appear through the finish, use a fine artist's brush to fill the scratch with shellac.Rub out the finish to even out the color between the repaired scratch and the surrounding finish.hen pad or brush on a series of coats of shellac and rub it out until the finish is even.
