A solid wood floor can be refinished more times than an engineered floor, right?
Most of the UV cured urethanes that are used today are so durable that it should take many years before you should have to refinish your wood floor. There is a misunderstood belief that 3/4″ solid oak floors can be refinished over and over again. This is absolutely not true. A solid wood floor cannot be re-sanded once you get down to the tongue, which means only the top 1/8″, or so, is sandable. The top ply on most engineered wood floors is 1/8″ also, so both solid or engineered wood flooring can be re-sanded 2 to 3 times. The point here is when buying a wood floor do not buy it based on how many times you think it can be re-sanded.
