How Can I Remove Green From My Fence?

Your wooden fence has stood resilient through many harsh UK winters, but now you've noticed a green hue creeping across it. This isn't just an eyesore; it's algae buildup, which can accelerate the wood's deterioration, particularly in moist, shaded areas.

But don't worry—removing green algae from your fence is straightforward. Here’s how to effectively tackle the problem:

1. Prepare the Cleaning Area
   
   If your fence borders a flower bed or garden, protect nearby plants with plastic sheeting before starting the cleaning process.
   
   
2. Mix Your Cleaning Solution
   
   Create a simple yet potent solution by mixing one part bleach with two parts warm water. Ensure you have rubber gloves on hand before handling the solution.
   
   
3. Scrub Away
   
   With your solution ready and gloves on, apply it generously to the algae-covered areas of your fence. Use a brush to scrub vigorously, working the solution into the algae spots until they begin to lift.
   
   
4. Wait and Rinse
   
   Let the bleach solution sit on the fence for 30 to 60 minutes to effectively break down the algae. Afterwards, rinse thoroughly with clean water.
   
   
5. Pressure Wash
   
   For a really good clean, employ a pressure washer to eliminate any lingering algae particles stuck to the wood. Keep a safe distance of at least 2 feet from the surface and operate the washer at a low-pressure setting to prevent any potential damage to the wood.
   
   
6. Allow Your Fence to Dry
   
   Once washed, allow your fence to dry completely. This process may take 24 to 48 hours, depending on weather conditions. Avoid applying paint or stain until the wood is fully dry to prevent trapping moisture.
   
   
7. Apply Stain and Sealant
   
   To prevent future algae growth, apply a new layer of waterproof stain and sealant to your fence. Wait for dry weather with temperatures between 50 and 80°F for optimal application. Before staining, address any damage by filling imperfections with wood filler. Use a brush for detailed work or a roller for broader sections to ensure thorough coverage.
