Soft, neutral tones make limestone a popular choice in a variety of building projects, including tile floors, fireplace hearths and outdoor walls, fences and patios. Builders often leave limestone unfinished to preserve its natural texture and tone. Without a protective seal, however, limestone has increased vulnerability to damage such as scratches. Fortunately, limestone's softness allows for the removal of light, medium or even deep scratches through abrasion techniques. Does this Spark an idea?
Instructions
Light Scratches
1. Dampen the wadded end of a clean cloth with mineral oil.
2. Rub the scuffed area, using medium pressure to buff out the scratches.
3. Wash the area with warm, soapy water. Rinse the stone, and then allow it to dry. Repeat the process if any signs of the scratches remain.
Medium Scratches
4. Sand the scratched area with silicon carbide 300-grit sandpaper, applying firm pressure to shear the stone surface until the scratches disappear. For large repair areas, use a power sander.
5. Massage the sanded area with mineral oil, using a clean cloth.
6. Wash the area with warm, soapy water. After the limestone dries, inspect the area. Repeat the process if there is still evidence of the scratches.
Deep Scratches
7. Abrade deep scratches with 100-grit silicon carbide sandpaper, using a power sander. Once the scratches become nearly invisible, finish sanding with 300-grit sandpaper.
8. Rub the sanded limestone surface with mineral oil.
9. Clean the stone with soap and water, and leave it to dry. If any of the scratches still show, sand the area again with 300-grit sandpaper, then re-treat with mineral oil and wash the area thoroughly.
