Wood Floor Gap Fillers - One question I have been asked time and again on the years working in the wood flooring industry is; can my old fitted wooden floor be sanded and refurbished? Most folks realize that parquet floors or first floor boards could be sanded back to produce a lovely finished flooring, but what things to do having a fitted wooden flooring is a bit more confusing.
Firstly you should learn what kind of flooring you have, & most importantly it is wood. If your flooring is a wood effect laminate then I am afraid the only alternative would be to replace it.
There are two kinds of fitted wooden flooring; the great news and engineered and solid wood flooring is, both can be sanded and refurbished to look as new as the day. As it includes the same construction engineered wooden flooring can occasionally be mistaken for laminate. Engineered wood flooring includes a thin layer of real wood, generally between 3-5 mm bonded to a foundation of either ply or MDF board, due to its construction and that it's fitted together with a tongue and groove, it also remains quite flat.
Solid wood flooring is more expensive to make and will necessarily cost more to purchase, but in my opinion, it is not as good a product as engineered as it is more prone to warping.
