Shellac Bars are used to fill small holes and chips in the face or on the edges of marbles, granites and natural stones. Simply heat the melting stick with a low heat flame or a melting iron and drip the liquid into the holes or chipped areas, leaving the material higher than the surface, and let harden. Once the shellac is hard use a fine grain steel wool (#0) and smooth the hardened shellac flush to the surface. By using your low heat flame you can quickly pass over the surface of the smoothed out area which will give the shellac a glistened, polished look. DO NOT USE POLISHING COMPOUNDS TO TRY TO POLISH THE REPAIRED AREA. IT WILL RE-MELT AND OPEN UP THE REPAIRED AREA AGAIN.
