Repairing A Floating Wood Floor - 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 be sanded and refurbished? A lot of folks know things to do having a fitted wooden floor is a little more confusing, although that original floor boards or parquet floors can be sanded back to create a finished floor that is wonderful.
You need to find out it is wood, & most importantly what sort of floor you've got. In case your floor is a wood effect laminate then I am afraid the only alternative would be to replace it. Laminate flooring comes in varying degree of quality, but most of the time it's basically a wood effect print stuck to an MDF or plywood board using a lacquer on top, sanding it'd sand the paint off and destroy the floor.
There are two forms of wooden flooring that is fitted; engineered and solid wood flooring and also the good thing is, both refurbished and could be sanded to look as new as the day they were fitted. As it has a similar building, engineered wooden flooring can sometimes be mistaken for laminate. Engineered wood flooring has a thin layer of real wood, typically between 3-5 mm bonded to your foundation of ply or MDF board, due to its building and that it is fitted together using a tongue and groove, it also stays really level.
Solid wood flooring is more expensive to make and certainly will inevitably cost more to purchase, but in my opinion, it isn't as great a product as engineered as it's more inclined to warping.
