What Is the Upkeep on Exterior Hardwood Flooring?

Basic Upkeep

• Sweep the flooring regularly to remove leaves and dirt. Use a plastic shovel, instead of a metal version, to remove snow, as the metal edge can pierce the flooring. Shovel away snow immediately to prevent water damage. Wash the flooring with a garden hose. Spray out any debris between the boards, because debris stuck between the flooring can result in mildew and rot. Scrub the flooring to get rid of tough-to-remove dirt. Use a scrub brush, a solution of water and a mild laundry detergent.

Color Retention

• Products called brighteners or restorers can renew the color of weathered exterior flooring. While the products don't add color, they remove deeply ingrained dirt and mildew to allow the original color to shine through. As another mildew-removing option, bleach is an effective cleaner. Dilute the bleach with three parts water and add a few drops of a mild liquid detergent. Rinse the bleach solution from the deck and allow one to two days of drying time before finishing.

Finishes

• Applying an additional finish over the manufacturer's finish offers more protection against cracking and water damage. Test the exterior flooring's finish every six months. Sprinkle a few drops of water on it. If the water beads the finish is in good shape, but if not it's time to refinish. Finishes not only add color and luster to the hardwood, but also coat and seal the wood. The coating offers protection from mildew growth and blocks damaging UV rays.

Warnings

• Restoration products are sometimes caustic and can damage the wood surface, especially if the wood is a soft variety such as red cedar; follow the application directions as specified. Use power washers sparingly to clean the wood, as the forceful water may damage soft wood. Wear rubber gloves and eye protection when working with acid-based cleaners or decking products.
