Brazilian Tiger Wood Engineered Flooring - One question I have been asked time and again on the years working in the wood flooring business is; can my old wooden floor that is fitted refurbished and be sanded? Lots of people have a wooden floor in their own house which has been down for 6-10 years that is appearing tired, dull, has scratches or spots in and has definitely seen better days. Most people understand what things to do having a fitted wooden floor is a bit more confusing, although that original floor boards or parquet floors might be sanded back to create a finished floor that is wonderful.
You need to determine what kind of floor you've got, and most importantly it is wood. I'm afraid the only real alternative would be to replace it, in case your floor is a wood effect laminate then. Laminate flooring comes in varying level of quality, but most of the time it is basically a wood effect print stuck to an MDF or plywood board with 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 good thing and engineered and solid wood flooring is, both could be sanded and refurbished to look as new as the day they were fitted. Engineered wooden flooring will often be mistaken for laminate as it includes a similar building. Engineered wood flooring includes a thin layer of real wood, typically between 3-5 millimeters bonded to some base of ply or MDF board, because of its building and that it's fitted together with a tongue and groove, it also stays very level.
Solid wood flooring is more expensive to make and certainly will inevitably cost a lot more to purchase, but in my opinion, it is not as good a product as engineered as it is more inclined to warping.
