AvatarByMahlon Boehs Outdoor Woodwork & Landscaping


A wooden deck can be the crown jewel of your outdoor space, providing a perfect spot for relaxation, entertaining, and enjoying nature. However, exposure to the elements can take a toll on its beauty and integrity over time. If your deck is looking worn, faded, or weathered, it might be time to consider refinishing it. This process not only revitalizes the appearance of your deck but also extends its lifespan, ensuring that it remains a cherished part of your home for years to come. In this article, we will guide you through the essential steps and considerations for refinishing a wood deck, transforming it from drab to fab.

Refinishing a wood deck involves several key steps, each crucial to achieving a stunning and durable finish. First, it’s important to assess the current condition of your deck to determine the necessary preparations. This may include cleaning, sanding, and repairing any damaged boards to create a solid foundation for the new finish. Once the surface is ready, you can choose the right stain or sealant that not only enhances the wood’s natural beauty but also provides protection against moisture, UV rays, and wear.

Throughout the refinishing process, attention to detail is paramount. From selecting the right tools to applying the finish evenly, each step

Preparation for Refinishing

Before you begin the refinishing process, thorough preparation is essential to ensure a successful outcome. Start by removing all furniture, planters, and any other items from the deck. This will give you a clear working area and prevent damage to your belongings.

Next, inspect the deck for any damage. Look for loose boards, splinters, or signs of rot. Any damaged areas should be repaired before proceeding. Use wood filler for small holes and replace any severely damaged boards.

Cleaning the deck is the next critical step. Use a deck cleaner or a mixture of mild detergent and water to scrub the surface. A pressure washer can effectively remove dirt and grime, but be cautious to avoid damaging the wood. Allow the deck to dry completely, as moisture can interfere with the refinishing process.

Choosing the Right Finish

Selecting the appropriate finish is crucial for the longevity and appearance of your deck. There are various types of finishes available, each with its characteristics:

  • Stains: These penetrate the wood and provide color while allowing the grain to show through. They come in semi-transparent to solid formulations.
  • Sealants: These provide a clear protective layer over the wood, enhancing its natural appearance.
  • Oil-based finishes: These offer excellent penetration and durability but may require longer drying times.
  • Water-based finishes: These dry quickly and have lower volatile organic compounds (VOCs) but may require more frequent reapplication.
Finish Type Durability Application Ease Drying Time
Stain Moderate to High Moderate 2-4 hours
Sealant High Easy 1-3 hours
Oil-based High Moderate 6-12 hours
Water-based Moderate Easy 1-2 hours

Application of the Finish

Once you have selected your finish, it is time to apply it. Begin by stirring the finish thoroughly to ensure an even consistency. Use a high-quality brush or roller to apply the finish, working in small sections. For best results, follow these steps:

  • Start at one end of the deck and work your way to the other, applying the finish evenly.
  • Use long strokes to ensure a smooth application, avoiding excessive buildup in corners or edges.
  • If using stain, consider back-brushing to ensure even penetration into the wood.
  • Allow the first coat to dry completely as per manufacturer instructions before applying a second coat.

It is often advisable to apply at least two coats for optimal protection, especially in high-traffic areas. Always ensure proper ventilation during the application process, particularly if using oil-based products.

Maintenance After Refinishing

After refinishing your deck, proper maintenance is key to extending its life. Regular cleaning and periodic reapplication of finish will help preserve the wood’s appearance and integrity. Follow these maintenance tips:

  • Clean the deck regularly using a gentle cleaner and a soft brush.
  • Reapply your chosen finish every 1-3 years, depending on the product and weather conditions.
  • Inspect the deck for damage at least once a year, addressing any issues promptly to prevent further deterioration.

By following these steps, you can enjoy a beautiful and durable wood deck for years to come.

Assessing the Condition of Your Deck

Before starting the refinishing process, it is essential to evaluate the current state of your wood deck. This assessment will determine the necessary steps to restore its appearance and integrity.

  • Check for Damage: Look for signs of rot, splintering, or insect infestation. Use a screwdriver to probe soft spots.
  • Evaluate the Finish: Identify whether the existing finish is peeling, fading, or completely worn away.
  • Moisture Content: Use a moisture meter to gauge the wood’s moisture content. Ideally, it should be below 15% for refinishing.

Preparing the Deck Surface

Proper preparation is critical for achieving a successful finish. Follow these steps to ensure the surface is ready.

  • Clean the Deck:
  • Sweep away debris and dirt.
  • Use a pressure washer to remove old stains, dirt, and mildew. Maintain a safe distance to avoid damaging the wood.
  • Allow the deck to dry thoroughly, typically 24-48 hours.
  • Sand the Surface:
  • Sand any rough areas or splintered spots with a belt or orbital sander using 60-80 grit sandpaper.
  • For hard-to-reach areas, consider using a sanding block.
  • Vacuum the dust and debris after sanding.

Applying Stain or Sealant

Choosing the right product and application method is vital for durability and appearance.

  • Selecting the Right Product:
  • Stains: Choose between semi-transparent, solid, or transparent stains based on desired look and UV protection.
  • Sealants: Opt for water-based or oil-based sealants depending on your preference for drying time and finish.
  • Application Method:
  • Use a high-quality brush or a roller for even coverage. A sprayer can also be used for larger areas.
  • Apply the stain or sealant in the direction of the wood grain.
  • Ensure even application; avoid pooling and drips.

Drying and Curing Time

Allow adequate time for the product to dry and cure, as this affects the longevity of the finish.

  • Drying Time:
  • Water-based products typically dry within 2-4 hours.
  • Oil-based products may take 6-8 hours to dry.
  • Curing Time:
  • Full curing can take up to 2 weeks for oil-based finishes and about 1 week for water-based finishes.

Regular Maintenance

To prolong the life of your refinished deck, establish a regular maintenance routine.

  • Cleaning: Sweep and wash the deck regularly to prevent dirt buildup.
  • Reapplication: Monitor the finish and reapply stain or sealant every 1-3 years, depending on exposure to elements and wear.
  • Inspection: Conduct seasonal inspections for signs of wear, damage, or moisture accumulation.
