Epoxy Floor Coating Over Wood Subfloor - One question I've 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? Many people realize that parquet floors or original floor boards might be sanded back to produce a wonderful finished floor, but what things to do with a fitted wooden floor is a little more confusing.
You need to discover what kind of floor you have, and most importantly it is wood. I am afraid the sole option would be to replace it if your floor is a wood effect laminate then. Laminate flooring comes in varying level of quality, but most of the time it is essentially a wood effect print stuck to an MDF or plywood plank using a lacquer on top, sanding it ruin the floor and would sand off the paint.
There are two types of wooden flooring that is fitted; the good news as well as solid and engineered wood flooring is, both refurbished and might be sanded to look as new as the day. As it has an identical construction engineered wooden flooring will often be mistaken for laminate. Engineered wood flooring includes a thin layer of real wood, generally between 3-5 mm bonded to some base of either ply or MDF board, because that it's fitted together using a tongue and groove and of its construction, it also stays really level.
Solid wood flooring is more expensive to make and will necessarily cost a lot more to buy, but in my opinion, it's not as good a product as engineered as it is more prone to warping.
