Seal Wood Floor Under Carpet - One question I've been asked time and again over the years working in the wood flooring industry is; can my old wooden floor that is fitted refurbished and be sanded? Many folks know that parquet floors or original floor boards may be sanded back to create a lovely finished flooring, but things to do with a fitted wooden flooring is a little more confusing.
You must determine what kind of flooring you might have, and most importantly that it is wood. I am afraid the only real alternative is to replace it if your flooring is a wood effect laminate then. Laminate flooring comes in varying degree of quality, but most of the time it is actually a wood effect print stuck to an MDF or plywood plank with a lacquer on top, sanding it destroy the floor and would sand the paint off.
There are just two forms of fitted wooden flooring; the good news as well as solid and engineered wood flooring is, both refurbished and could be sanded to look as new as the day. As it has an identical building, engineered wooden flooring can occasionally be mistaken for laminate. Engineered wood flooring includes a thin layer of real wood, typically between 3-5 mm bonded to your base of MDF or ply board, due to its building and that it is fitted together with a tongue and groove, it also remains very level.
Solid wood flooring is more expensive to make and will necessarily cost a lot more to purchase, but for me, it isn't as great a product as engineered as it is more inclined to warping.
