When we talk about floor wear, we're referring to the protective finish, not the wood itself. The Optima 100 finish is made of urethane with aluminum oxide, the toughest product in the industry. Even so, it is still vulnerable to abrasives.

Tracked‑in sand and hard surfaces that rub against the floor (chair and furniture legs, etc.) will eventually wear down even the most resistant protective finish.

To protect your floor against premature wear

• Place felt pads (or any other suitable protection) under chair and furniture legs. Ensure that the pads are kept clean and in good condition.

• Sweep and vacuum the floor regularly to remove all sand and other abrasives. An outside mat and an indoor carpet at each door will help keep gritty dirt from getting tracked through the house.
