What can be repaired and what needs a new plank
Repair in place works for light scratches, small gouges, nicks, and small burns where the damage is limited to a spot. Replacement is the better fix when a gouge goes through the printed design layer over a large area, when the plank has swelled or delaminated from water, when the locking edge is broken, or when a burn is large. A floor where the wear layer is worn through across whole rooms cannot be refinished, because there is nothing to sand back. In that case new flooring is the real answer, and we will say so instead of selling a repair that will not last.
