Using a pressure washer on your wood deck can effectively clean dirt, grime, and mildew, giving it a fresh look. Here's how to do it safely and effectively:
Prepare Your Deck
- Clear the Deck: Remove all furniture, plants, and other objects from the deck.
- Sweep or Vacuum: Remove loose debris like leaves and dirt.
- Inspect for Damage: Check for loose boards, cracks, or other damage. Repair any issues before pressure washing.
- Protect Surrounding Areas: Cover nearby plants, windows, and siding with plastic sheeting or drop cloths to prevent damage from stray water.
Choose the Right Pressure Washer
- Pressure Settings: Choose a pressure washer with adjustable pressure settings. For wood decks, a lower pressure setting (1,200 to 1,500 PSI) is typically recommended.
- Nozzle: Use a wide-angle nozzle (typically a 40-degree tip) for cleaning decks. This provides a wider spray pattern, reducing the risk of damaging the wood.
Wash Your Deck
- Start with a Pre-Wash: Use a garden hose to rinse the deck thoroughly, removing any remaining loose debris.
- Apply Cleaning Solution: If needed, apply a deck cleaner specifically designed for wood. Follow the manufacturer's instructions for dilution and application.
- Pressure Wash the Deck: Start at the highest point of the deck and work your way down. Use overlapping passes to ensure even coverage.
- Rinse Thoroughly: After cleaning, rinse the deck with clean water to remove any residue.
- Allow to Dry: Let the deck dry completely before applying any sealant or stain.
Additional Tips
- Work in Sections: Divide the deck into smaller sections to make the cleaning process more manageable.
- Use a Gentle Touch: Avoid holding the pressure washer in one spot for too long, as this can damage the wood.
- Check for Leaks: Inspect the pressure washer regularly for leaks.
- Wear Safety Gear: Always wear eye protection, gloves, and closed-toe shoes when using a pressure washer.
Conclusion
By following these steps, you can use a pressure washer to effectively clean your wood deck without damaging it. Remember to choose the right pressure setting and nozzle, and always work safely.
