Staining hardwood floors.
Hardwood floor staining is not the same as hardwood floor finishing. Staining hardwood floors changes the natural colour, (usually darker) of a hardwood floor, while still allowing the the wood grain to show. Finishing is the application of protective coats of oil-base or water-base sealer and finish for long lasting durability.
Staining hardwood floors dark or a certain earth-tone is done to compliment design ideas for a unique, custom hardwood floor, or disguise imperfections in older floors that are minimized by the darker stain.
