Grab a hair dryer or a heat gun to repair a gouge in resilient flooring. Use it to warm the area around the rip, then stretch and smooth the material back into place. Squeeze a thin, even layer of acrylic glue underneath the tear (and on the subfloor, if visible). Weight it down so that it lies flat; let dry. Any remaining gaps can be filled with layers of nail polish in a color close to that of the flooring, say the Vinyl Ladies
, an interior restoration and repair company. The polish will seep into and bond with the flooring.
