In order to maintain the beauty of your wooden deck, it is important to keep it clean and free from dirt, grime, and mold. One popular method to achieve this is power washing. However, many people are concerned about whether power washing can damage their wooden decks. In this article, we will discuss the dos and don’ts of power washing a wooden deck to ensure it remains in optimal condition.
Understanding the Power Washing Process
Power washing is a high-pressure cleaning technique that utilizes a machine to spray water at a forceful rate. It is commonly used to clean and remove tough stains from various outdoor surfaces, including decks. While power washing can be effective in removing dirt and grime, it can also damage the wood if not done correctly.
Dos and Don’ts of Power Washing a Wooden Deck
To ensure you do not cause any damage to your wooden deck while power washing, it is crucial to follow these dos and don’ts:
- Do Use the Right Pressure: When power washing a wooden deck, it is essential to use the appropriate pressure setting. Avoid using extremely high pressure as it can strip away the wood, leaving behind a damaged surface. Use a pressure washer with an adjustable nozzle to regulate the pressure and start with a low setting. If necessary, gradually increase the pressure until you achieve optimal cleaning without causing harm.
- Don’t Hold the Nozzle Too Close: Holding the power washer nozzle too close to the deck can result in damage. Keep a safe distance of at least 12 inches between the nozzle and the wood surface to prevent excessive force from causing splintering or gouging.
- Do Pre-Treat with a Deck Cleaner: Before power washing the deck, it is advisable to pre-treat the surface with a deck cleaner. This will help loosen up any dirt or stains, making the power washing process more effective. Follow the instructions on the deck cleaner product and allow it to sit for the recommended time before proceeding with power washing.
- Don’t Use Hot Water: While power washing, avoid using hot water, as it can cause the wood to expand and potentially damage the deck. Stick to cold or lukewarm water when using a power washer.
- Do Keep the Wand Moving: To prevent concentrated pressure on specific areas of the deck, it is crucial to keep the wand moving while power washing. Maintain a constant pace and even coverage to avoid leaving marks or etching the wood.
- Don’t Use Excessive Force on Loose Boards: If your deck has any loose or damaged boards, avoid applying excessive pressure to these areas. Power washing can worsen the condition of weak spots, leading to further damage. Instead, repair or replace any damaged boards before power washing.
- Do Apply a Sealant or Stain: After power washing, it is recommended to apply a sealant or stain to protect the wood and enhance its appearance. This will help to prevent moisture absorption and potential damage caused by the elements.
Power washing can be a safe and effective method to clean a wooden deck if done correctly. By using the right pressure, maintaining a safe distance, pre-treating with a cleaner, and keeping the wand moving, you can avoid causing damage. Applying a sealant or stain after power washing will further protect your deck and prolong its lifespan. By following these guidelines, you can enjoy a clean and well-maintained wooden deck for years to come.
