How to Clean and Seal Your Wood Deck

A wood deck is not only a valuable addition to your outdoor living space but also an investment that deserves proper care and maintenance. Regular cleaning and sealing are essential to preserve the beauty and longevity of your deck, protecting it from the elements and ensuring it remains a welcoming oasis for years to come. In this guide, we’ll walk you through the steps to effectively clean and seal your wood deck.

Step 1: Gather Your Supplies

Before you begin, gather the necessary cleaning and sealing supplies:

•  Broom or leaf blower
•  Garden hose with a spray nozzle
•  Deck cleaner or mild soap
•  Scrub brush or pressure washer
•  Safety gear (gloves, eye protection)
•  Deck sealer or stain
•  Paint roller or brush
•  Drop cloths or plastic sheeting

Step 2: Clear the Deck

Remove all furniture, plants, and accessories from the deck. Sweep away leaves, dirt, and debris using a broom or leaf blower. Clearing the deck ensures that the cleaning and sealing processes are thorough and even.

Step 3: Cleaning the Deck

Mix a deck cleaner solution as per the manufacturer’s instructions. Alternatively, you can use a mixture of mild soap and water. Apply the solution to the deck’s surface and scrub using a scrub brush or a low-pressure pressure washer. Pay special attention to hightraffic areas and spots with stains or discoloration. Rinse the deck thoroughly with a garden hose to remove all traces of the cleaning solution.

Step 4: Sanding (If Necessary)

Inspect the deck for any rough or splintered areas. Sanding these spots smooth helps ensure a uniform surface for sealing and prevents splinters. Use a medium grit sandpaper and follow the wood’s grain.

Step 5: Drying Time

Allow the deck to dry completely before proceeding to the sealing step. Depending on the weather and humidity, this may take a day or two. Make sure the wood is dry to the touch to ensure proper adhesion of the sealant.

Step 6: Applying the Sealer or Stain

Choose a high quality deck sealer or stain that suits your deck’s wood type and your desired finish. Read and follow the manufacturer’s instructions for application. Using a paint roller or brush, apply the sealer evenly, following the wood’s grain. Pay attention to the edges and corners of the deck. Avoid applying the sealer too thickly, as it can lead to an uneven finish.

Step 7: Second Coat (If Needed)

In some cases, a second coat of sealer or stain may be necessary for optimal protection and coverage. Refer to the product instructions for guidance on whether a second coat is recommended and how long to wait between coats.

Step 8: Cleanup

Properly dispose of any used materials, such as brushes or rollers. Allow the sealer to dry as recommended by the manufacturer before placing furniture or other items back on the deck.

Step 9: Regular Maintenance

Regularly inspect and clean your deck to prevent dirt buildup, mold, and mildew growth. Sweep away debris and rinse with a hose as needed. Perform a water droplet test to check if the sealer is still effective; if water beads up, the sealer is doing its job.
