How to repair scratches on sandstone surfaces

Many homeowners choose to use sandstone for a variety of surfaces in the home, including: tile, kitchen countertops, wallcovering, patios, steps, showers, etc. Because this natural porous stone is sealed after installation to protect against moisture (which can cause all kinds of damage, including cracks and discoloration), any scratches that occur to the surface are often contained in the sealant and not passes to the sandstone below. . To repair these types of artificial scratches, you will need to follow this simple process:

Since you will be working with some chemicals and other solutions that do not react very well without skin, you will need to make sure you wear a good pair of rubber gloves before you begin. You can then mix a solution consisting of 2 liters of warm water and a quarter cup of powdered oxygen bleach. Stir the two together until the lye has completely dissolved.

Next, you will need to take a plastic scrub brush and dip it in the previously prepared solution. Use the brush to scrub the scratched areas of the sandstone as this will remove dirt and grime from inside the marks. Next, use a cloth that you have dampened with clean water to clean the sandstone and remove any remaining solution. Use a second cloth to dry the sandstone.

Next, you will need to take a wad of # 0000 grade steel wool and moisten it with a little cold water. Use the steel wool to rub the scratches into the surface of the sandstone until you can no longer see them. Do not use a heavier grade steel wool, as this could further damage the sandstone. If you notice that the scratches are much deeper than originally thought, you should seek the advice of a professional.

To finish, you will need to apply a thin coat of sandstone sealer to the surface of the pavers with the applicator provided. Before you begin, you will need to make sure the area is well ventilated by opening nearby doors and windows. Be sure to follow the attached manufacturer’s instructions and allow the first coat to dry completely before adding a second coat. Once you have applied the final coat, you will need to allow the sandstone to dry for at least 24 hours before attempting to walk or use the area again.
