Remove damaged areas and apply adhesive to seal seams
Because vinyl flooring is soft, it is easily damaged. To repair a damaged area:
Cut off the damaged part: Use a utility knife and straight edge to carefully cut off the damaged part. Follow the floor pattern to make the patch less noticeable.
Remove the damaged part: Take out the damaged part of the floor.
Cleaning the subfloor: Remove all adhesive from the subfloor.
Dicing: Use a utility knife and straight edges to cut matching pieces that fit the opening.
Paste the patch: Paste the patch in place with a vinyl adhesive.
Remove excess glue: Clean excess glue with mineral oil.
Sealed seams: Use vinyl seam sealants to fuse patches to the original floor.
