Wood flooring has the ability to withstand any lifestyle. There are many kinds of wood, each with different hardness and durability. These were measured using the Janka scale. The Janka scale shows the possibility of abrasion or depression of wood species. For example, the grade of domestic black walnut is about 1010, while that of Brazil walnut is 3680, three times higher than that of domestic black walnut. If you choose the right Brazilian walnut for your floor, you will find that it is not easy to wear and tear. Moreover, the addition of finishing agent can significantly reduce the wear on the wood floor.
