There are two principal types of finishes used on wood floors – penetrating seals and surface finishes. Each requires about the same care; but when it comes to removing stains or restoring the finish in heavy traffic areas, methods vary.
It is important for you to know how your floors were finished so you can decide on the proper floor care product. Your builder, realtor or flooring installer/finisher should be able to tell you what type of finish was used.
It will also be helpful to know the brand names of the finishing products, particularly the final finish coat. If your floors are factory finished note the name of the manufacturer. Keep this information in your household data file to help you determine the proper floor care products.
