how to fill gaps in engineered wood floor
Ordinarily, you can âfillâ the gaps with wood filler, putty, or with pieces of rope â and then finish with stain to match the floor. The latter is an older method of filling gaps, and not only serves as a way to fix floor gaps, but also will help keep any drafts that come up through the floor to a minimum as well.illers are best used when the gaps are narrow and the floor is not riddled with them. One thing to note about using fillers to fix floor gaps; as the humidity changes and the floor expands and contracts, the filler may actually be forced out when the floor expands to accommodate additional humidity.
