What’s the best way to best maintain cypress siding?
A transparent stain can be used to allow the natural wood grain to be visible and should be reapplied every 3-5 years, based on the amount of direct sunlight exposure. If left to natural weathering (graying), a clear penetrating sealer should be applied every 3-5 years to give the wood a water repellant finish. It is wise to wash down the exterior siding and trim with a mild bleach solution to kill any fungus and mold that would otherwise be trapped under the new coating. We recommend the following products: Olympic, Penofin, Sikkens, or Flood. These products are good for siding, trim, and decks. Pressure washing is also recommended for cleaning a wood surface prior to refinishing. However, be sure to let the wood dry throughout prior to refinishing. Note: When using a pressure washer to clean wood, do so at low pressure to avoid damaging the wood.
