How to Keep Your Redwood Fence Looking Like New

Redwood offers a natural ability to stand up to insects and weather conditions, making it a durable fencing material. The oils in redwood cause the wood to resist rot and decay. In addition, a redwood fence provides a splash of color to a yard. Over time, though, the red can fade into a worn gray. Protecting the wood from the elements will keep your redwood fence looking new and preserve the color.

Preserve the beauty of your redwood fence.
  1. Wash the fence with trisodium phosphate and water. Scrub dirt and stains, using a scrub brush. Clean tough stains with oxygenated bleach. You can also use a commercially prepared redwood deck and fence wash.
  2. Allow the wood to dry completely. Drying times vary, depending on temperature and humidity.
  3. Lay a tarp over nearby plants, bushes, decks and patios to protect them from splashes, drips and overspray.
  4. Apply a coat of mildew-resistant, UV-blocking wood sealer to the fence. Look for a waterproofing sealer that is specific to redwood. Apply the sealer with a wide paintbrush, paint roller or painter sprayer. If you are using a paintbrush, follow the grain and paint in one direction.
  5. Allow the fence to dry for 48 to 72 hours, depending on the weather, before touching it.
