they can be refinished , up to 3 times.but not by sanding, (with sand paper) you use window screen,and take off the finish layer only. p.s. most floors with a factory finish will never need to be refinished ( unless you mop the floor,NEVER use water to clean a wood floor,only a wood floor cleaner or polish)

Carpet man is referring to what we call "screen and coat." Screening removes the the surface finish layer or two and allows for a proper application bond for the recoat. Some of the better prefinished manufacturers make a product that can be completely refinished several times over by a knowledgable professional.

Now that we have many alumnide oxide finishes on the market screening and coating isn't as simple as it once was.
