Fixing Wood Floors Scratches - One question I have been asked time and again over the years working in the wood flooring industry is; can my old fitted wooden floor refurbished and be sanded? Many people have a wooden floor in their house that's been down for 6-10 years which is appearing tired, lifeless, has stains or scratches in and has definitely seen better days. Many people understand that parquet floors or original floor boards might be sanded back to create a lovely finished floor, but things to do having a fitted wooden floor is a little more confusing.
You need to discover that it is wood, & most importantly what sort of floor you've got. I am afraid the only real alternative is to replace it, if your floor is a wood effect laminate then.
There are just two forms of fitted wooden flooring; engineered and solid wood flooring and the good thing is, both may be sanded and refurbished to look as new as the day. Engineered wooden flooring will often be mistaken for laminate as it's a similar construction. Engineered wood flooring has a thin layer of real wood, typically between 3-5 millimeters bonded to a base of ply or MDF board, due to its construction and that it's fitted together using a tongue and groove, it also stays really level.
Solid wood flooring will necessarily cost a lot more to buy and is more expensive to make, but for me, it is not as good engineered as it's more prone to warping.
