This is a perimeter spread floor;if it has a
vinyl backing smooth not felt like it most
likely can be fixed.I done many.You a heat gun
or hair dryer,Armstrong Interflex glue or a
staple gun,also duct tape,clean rags.Slowly
heat the floor all around shrunken area
start to pull floor to spread glue,use tape to
help pull & hold floor,wipe with wet rag.
Floor should have baseboard all around.
