Effective Ways to Clean and Seal a Wooden Fence

When it comes to maintaining a healthy and attractive wooden fence, regular cleaning and sealing are crucial. If your fence has not been treated in years and is now covered in green algae and mold, the first step is to thoroughly clean it. Here are some effective methods and products you can use to restore your fence to its former glory.

How to Clean a Wooden Fence with Green Algae

Using Bleach and Vinegar

One method to clean a wooden fence is to use a dilute mixture of water, bleach, or water and vinegar. This solution can be painted onto the fence and left to sit for a while. After some time, give it a quick scrub with a brush or broom. Finally, rinse the fence thoroughly with a hose, but avoid using a powerful power hose as it can damage the wood.

Using a Pressure Washer

For a more efficient cleaning method, a pressure washer is highly recommended. It will quickly remove algae, mold, and fungus without the need for soaking and scrubbing. Make sure not to hold the nozzle too close to the wood to avoid raising a nap on the surface. Carefully clean the endgrains and apply a good resealer for thorough protection. Two or three coats of sealer will ensure that the wood is well-protected.

Using Commercial Wood Cleaners

Commercial wood cleaners can be sprayed onto the fence using a pump sprayer. These products come in two types: one for pressure washers and another for household water pressure. The pressure washer type offers quicker work and better penetration, while the household type works well for mold and fungus that is not too deep. While the household type is less powerful, it still effectively cleans the fence. After cleaning, let the wood dry and then apply a sealer or stain as needed.

Best Practices for Sealing Your Wooden Fence

After cleaning, the next step is to reseal your fence to ensure it remains protected from the elements. You can use an exterior wood sealer or stain to achieve this. One product, 'Protim' clear, is effective in extending the life of the wood. This clear sealer can be applied to the wood when it is dry. After applying the Protim sealer, let it dry before sealing the wood to maximize its protective properties.

Additional Tips and Recommendations

Before starting the cleaning process, it is important to follow safety precautions and adhere to the product instructions for the best results. Always wear protective gear such as gloves and eyewear to avoid injury. Also, consider renting a good pressure washer machine if you do not have one available.

A Personal Experience
