How to Repair a Sandstone Sculpture
- 1). Remove rough edges around the area to be restored. Use a small rasp (metal file) and work slowly, running the rasp over the area to be sanded with slight pressure. File only to level the surface around the area to be repaired.
- 2). Brush away any filings and inspect the repair area. Run your fingers over it to ensure the repair area is level. If further sanding is required, continue to file with a light pressure, working slowly.
- 3). Mix sandstone filler or mortar according to directions on the box. Ensure the color of the filler matches the color of the sculpture as closely as possible. Apply the filler to cracked surfaces and gouges by pressing to avoid feathering of the filler material.
