Method 3 - Use Liquid Joint Sealant To Repair Scratch
This is an option if the scratch is very deep. You can buy a liquid joint sealant and apply it to the affected area. Before doing so it is recommended:
Open windows in the area to work like this has a strong odor.
Clean the area to work.
Mark the area to be worked with tape.
Be very careful when applying so that everything is at the same level.
This type of product usually brings an applicator to do it, in case that is not the case you can place a small drop on the affected area and let it dry.
Once it is dry, you just have to remove the adhesive tapes carefully, and voila.
Method 4 - Partial Replacement For Irreparable Deep Scratches
If your vinyl floor has very deep scratches, then the best thing you can do is change the sheet.
Vinyl floors are usually offered with geometric structures. This has the advantage that you can partially replace damaged areas. Here, a part of the floor is simply renewed. Often times, this method of repair is the only way to remove especially deep scratches.
