Marks on the floor occur when wood fiber is crushed.

When this happens, the protective finish remains intact, simply molding to the shape of the hollow. Marking can be caused by heavy objects being moved or striking the floor, as well as by repeated rubbing or small impacts.

Marks are less apparent on a floor with a satin than a gloss finish. However, like with antique furniture, they are often viewed as a natural feature that adds to a floor's charm.

To avoid marks on the floor

• Protect the floor when moving heavy furniture such as a refrigerator. Use specially designed glides or slide the furniture on a piece of upside‑down carpet.

• For furniture and chairs with castors, use only castors designed for hard surfaces (wide rubber). Avoid hard ones made of plastic or wood.

• Watch for high heels, a dangerous enemy for any type of floor covering. Broken or worn heels can even damage a cement floor!
