Seal Wood Floor Before Staining - 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? Lots of people have a wooden floor in their house that's been down for 6-10 years which is appearing tired, dull, has stains or scratches in and has definitely seen better days. A lot of folks realize what things to do having a fitted wooden flooring is a little more confusing, although that original floor boards or parquet floors could be sanded back to create a finished flooring that is wonderful.
Firstly you have to learn that it is wood, and most importantly what kind of flooring you've got. I am afraid the sole alternative would be to replace it, if your flooring 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 either an MDF or plywood plank using a lacquer on top, sanding it destroy the floor and would only sand off the paint.
There are two forms of wooden flooring that is fitted; the great news and engineered and solid wood flooring is, both can be sanded and refurbished to look as new as the day they were fitted. As it includes a similar building engineered wooden flooring can sometimes be mistaken for laminate. Engineered wood flooring includes a thin layer of real wood, typically between 3-5 mm bonded to your base of either MDF or ply board, because that it is fitted together using a tongue and groove and of its building, it also remains really level.
Solid wood flooring is more expensive to make and will inevitably cost a lot more to buy, but for me, it isn't as good engineered as it is more inclined to warping.
