Bevelling a floor is the removal of material at the edges of each board. We bevel our floors on two sides (i.e., on two edges) or four sides (i.e., on all four edges).
What does the bevelling process offer? It visually separates the boards from each other, making the pattern look more natural. Bevelling also makes the individual boards appear slimmer, which optically enlarges and broadens the room.
Bevelling also has an important practical function – it prevents the possible effects of wood expansion, so you are guaranteed that your floor will remain the same for many years.
