There are only so many times that a hardwood floor can be refinished to sustain its youthful appearance. Continually performing the refinishing process causes the wood to become thinner and thinner. Since the hardwood needs to be smoothed first, this thinning of the wood is a result of the sanding that is required in the procedure. Eventually, the tongues and grooves that go together on the floorboards will fail to match up and lead to splintering and cavities in the wood; therefore, after undergoing the refinishing process several times, professionals advise that it’s best to replace the flooring entirely.
