Caring for a treated wood fence, especially a pressure-treated one, involves simple steps to maintain its longevity and appearance, primarily focusing on controlling moisture exposure and vegetation contact.
Essential Care for Pressure-Treated Fences
Unlike untreated wood, pressure-treated wood has been injected with preservatives to resist rot and insects. Therefore, some typical wood care steps may not be necessary or even recommended.
- Sealant Not Required: According to John Elaison, a sealant isn't necessary for pressure-treated wood because it already contains injected preservatives. This is a key difference from caring for untreated wood.
- Control Moisture: One of the biggest enemies of any wood, even treated wood, is excessive moisture. You should keep sprinklers from wetting the fence, as continuous soaking causes the wood to rot faster. Avoid directing irrigation systems directly at the fence.
- Manage Vegetation: Bushes, vines, and other plants growing directly on or against the fence trap moisture and can damage the wood. Bushes and vines should be kept off the fence to allow air circulation and prevent moisture buildup.
Additional Tips for Treated Wood Fence Maintenance
While the reference specifically addresses pressure-treated wood and the lack of need for sealant, general fence care practices can also apply:
- Regular Inspection: Periodically walk along your fence line. Look for loose boards, nails, or screws. Check for signs of insect activity or significant damage.
- Cleaning: If your fence develops mildew or grime, a gentle cleaning can refresh its look. Use a mild wood cleaner or a solution of water and soap with a soft brush. Rinse thoroughly, ensuring the fence dries properly afterward. Avoid high-pressure washing, which can damage the wood fibers.
- Repair Promptly: Address any minor issues like loose boards or nails immediately to prevent them from becoming bigger problems.
By focusing on keeping the fence dry and clear of vegetation, you can significantly extend the life of your treated wood fence, leveraging the inherent preservatives it contains.
