Why do prefinished floors have a slight bevel on the edges?
A. When two pieces of wood are butted up against each other there may be minor discrepancies in the heights of the boards. With site-finished floors, this is sanded out. To solve this problem with factory prefinished floors, the edges are sanded on a very small angle. This creates a micro bevel when the boards are put together and is one of the main visibly distinguishing features between the two types of floors.
