American Black Walnut Solid Wood Flooring - One question I've been asked time and again over the years working in the wood flooring industry is; can my old fitted wooden floor be sanded and refurbished? Lots of people have a wooden floor in their own house that's been down for 6-10 years which is appearing tired, dull, has spots or scratches in and has definitely seen better days. Most folks realize that parquet floors or first floor boards could be sanded back to create a wonderful finished flooring, but what to do with a fitted wooden flooring is a little more confusing.
You have to learn that it is wood, and most importantly what type of flooring you've got. I am afraid the sole option is to replace it if your flooring is a wood effect laminate then.
There are two types of wooden flooring that is fitted; the great news along with engineered and solid wood flooring is, both refurbished and could be sanded to look as new as the day they were fitted. As it has an identical building engineered wooden flooring will often be mistaken for laminate. Engineered wood flooring has a thin layer of real wood, generally between 3-5 millimeters bonded to some foundation of either MDF or ply board, due to its building and that it's fitted together with a tongue and groove, it also stays really flat.
Solid wood flooring certainly will inevitably cost more to purchase and is more expensive to make, but in my opinion, it isn't as good a product as engineered as it's more vulnerable to warping.
