Though limestone flooring can be a great option because it looks good while remaining durable, it can still suffer scratches due to its porous nature. In order to keep your floor looking its best, you will need to follow the few steps require to undertake a repair.

Step 1 - Inspection

The first step required before undertaking the repair of scratches in your limestone flooring is to thoroughly examine it. This will allow you to be aware of any scratches that many not be immediately evident that can be repaired at the same time. If necessary, place a piece of masking tape next to each scratch you find so that you don’t lose track of it.

Step 2 - Clean

In order to make the surface of your limestone flooring ready to accept the repair, you must ensure that it is clean and free from any obstruction. Move any items and furnishings away from the vicinity so that they are not at risk of being damaged. Use a broom or dustpan and brush to sweep up any loose dust and debris. More stubborn grime can be cleaned with a rag that has been dampened with water and a little elbow grease. Allow the floor to thoroughly dry naturally or wipe it with a rag.

Step 3 - Minor Scratches

For minor scratches such as scuff marks, begin by using a mild polishing compound that is available from hardware stores. This should be gently rubbed over the scratch to smooth the surface, while continually checking the status of it. Once you are happy with the finish, wipe away the compound with a damp cloth before brushing on some sealant. This is required to renew that which has been removed with the abrasive and protect the repair. Freshly mixed grout can be used as an alternative in this process.

Step 4 - Deeper Scratches

Scratches in the limestone flooring that cannot be rectified with the above process will require a little more work to repair. An epoxy resin can be mixed until it matches the color of your limestone floor. A putty knife can be used to gather up a small amount of the epoxy to apply it to the scratch until it has been filled. The surface can be smoothed by running a scraper across it to remove the excess. Leave this to dry completely before sealing the scratch by brushing on some sealant.

Step 5 - Severe Scratches

In the event that your limestone flooring has suffered scratches which are severe enough to be classed as gouges or chips, you will require spare slivers or strips of the limestone to repair. Flooring suppliers will often be able to supply fragments of limestone that can be used for repair. Apply the fragments with some epoxy and carefully wipe away the excess when they are securely in place. Leave it to thoroughly dry before sealing the repair site.
