Q: We dropped a piece of furniture on a sheet vinyl floor and caused a large tear. I have some leftover flooring that matches. What’s the best method to apply the patch?
A: It sounds like you’ll need to perform a surgical removal and replacement of the damaged area of flooring. Use a straight edge and a utility knife to cut out a square section of the flooring that surrounds the damage. If you have faux grout lines in the pattern of the floor, then hide your cuts in the lines. Peel up the damaged flooring and use a paint scraper to remove the old backing and adhesive. A hair dryer will help soften the adhesive. With your leftover vinyl flooring, cut a replacement piece that exactly matches the removed section. (Use the old piece as a template.) Test-fit the patch. Then, spread flooring adhesive on the subfloor using a notched trowel. Set the patch in place and roll out any air bubbles. After the adhesive sets, carefully apply a vinyl seam sealant to the edges.
