After choosing the material, its time to think about the finishing options. Choosing pre finished wood will save you a lot of time, but at the same time it is more expensive comparing to other options. Of course if you want to save some money, you will have to finish it after the installing, which will take you several days. During these days you will need to sand it, stain it, urethane it. The more time you spend and efforts you make, the better your ground will be protected.
Reclaimed flooring is another great option. Maybe, the biggest benefit of this option is that it will not show scratches as soon as first two options.
