How To Sand A Deck After Pressure Washing
After pressure washing your deck to remove dirt, grime, and mildew, the next step to achieve a smooth and beautiful finish is sanding. Sanding the deck helps to remove any remaining roughness, splinters, or raised wood fibers, leaving it ready for sealing or staining.
Step 1: Choose the Right Sandpaper
Before you begin sanding, it’s important to choose the right sandpaper grit. For initial sanding, use a coarse grit sandpaper, such as 60 or 80, to quickly remove any imperfections. Then, switch to a medium grit sandpaper, such as 120 or 150, for a smoother finish. Finally, use a fine grit sandpaper, such as 220, for a final touch.
Step 2: Prep the Work Area
Before you start sanding, make sure to prep the work area. Remove any furniture or plants from the deck and cover nearby plants or surfaces to protect them from dust. Additionally, put on protective eyewear, a mask, and gloves to protect yourself from the sanding dust.
Step 3: Sand the Deck
Start sanding the deck by working with the grain of the wood. Use a handheld orbital sander or a sanding block, applying moderate pressure. Move the sander or sanding block in long, smooth strokes, going over each section of the deck evenly. Be sure to sand both the horizontal and vertical surfaces of the deck boards.
Step 4: Check for Smoothness
After sanding the entire deck, check for smoothness by running your hand over the surface. If you feel any rough spots or imperfections, go over them with a finer grit sandpaper to achieve a consistent smoothness.
Step 5: Clean the Deck
Once you’re satisfied with the smoothness of the deck, use a broom or a leaf blower to remove any sanding dust. Then, clean the deck with a mild detergent and water to remove any remaining dust particles. Allow the deck to dry completely before proceeding to the next step.
Step 6: Apply Sealant or Stain
After sanding and cleaning the deck, it’s time to apply a sealant or stain to protect and enhance its appearance. Follow the instructions on the product label and use a brush or roller to evenly apply the sealant or stain. Allow it to dry according to the manufacturer’s recommended drying time before using the deck.
Following these steps will help you achieve a beautifully smooth and finished deck after pressure washing. By properly sanding and sealing the deck, you can extend its lifespan and maintain its aesthetic appeal for years to come.
Tips for Sanding a Deck After Pressure Washing
After pressure washing your deck, it is important to properly sand it to prepare the surface for staining or refinishing. Here are some tips to help you achieve the best results:
- Use the right equipment: Invest in a good quality orbital sander or a sanding machine specifically designed for deck sanding. This will make the process more efficient and give you better control.
- Start with coarse grit sandpaper: Begin by using a coarse grit sandpaper, such as 80 or 60 grit, to remove any remaining stains, dirt, or old paint. This will help you get a uniform surface and remove any rough spots.
- Follow up with finer grits: Once you have achieved a smooth and even surface with the coarse grit sandpaper, switch to a finer grit, such as 120 or 150 grit, to further refine the surface and remove any scratches left by the coarser grit.

- Keep the sander moving: Avoid leaving the sander in one spot for too long as it can cause uneven sanding. Keep the sander moving smoothly in a continuous motion to avoid any marks or indentations.
- Clean the dust: After sanding, make sure to thoroughly clean the deck to remove any sanding dust. Use a broom, vacuum, or a damp cloth to ensure all the dust particles are removed. This will help the stain or paint adhere properly to the surface.
- Inspect the surface: Once the deck is cleaned, inspect it closely to make sure there are no rough spots or imperfections. If necessary, do some touch-up sanding to achieve a smooth and flawless finish.
By following these tips, you can ensure that your deck is properly sanded and ready for the next step of the refinishing process. Take your time and pay attention to detail for the best results.
Preparing Your Deck
Before sanding your deck, it’s important to properly prepare it for the task. By taking the time to prepare your deck, you’ll ensure that the sanding process goes smoothly and helps your deck look its best.
First, clear your deck of all furniture, plants, and other items. It’s important to have a clean and clear surface to work with.
Next, inspect your deck for any loose or damaged boards. Replace any boards that are in poor condition to prevent any accidents or further damage.
Once your deck is clear and in good condition, give it a thorough cleaning. Use a deck cleaner and a scrub brush to remove any dirt, debris, or mildew. This will help the sanding process be more effective and give you better results.
After cleaning, rinse your deck thoroughly with water to remove any leftover cleaner and dirt. Allow it to dry completely before moving forward with the sanding process.
Lastly, protect any nearby plants or landscaping by covering them with plastic sheets or tarps. This will prevent any damage from the sanding dust or debris.
Following these steps to properly prepare your deck will help ensure a successful sanding process and a beautifully restored deck.
Choosing the Right Sandpaper
To achieve a smooth and even finish on your deck, it is crucial to choose the right sandpaper. Different types of sandpaper are available, each with its own grit level and material composition. Understanding the different options will help you determine the best sandpaper for your specific deck sanding needs.
Grit Level
The grit level of sandpaper refers to its coarseness or fineness. The higher the grit number, the finer the sandpaper. For deck sanding after pressure washing, it is recommended to start with a coarse grit sandpaper to remove any stubborn stains, old finish, or rough patches. Common grit levels for initial sanding range from 40 to 80. As you progress to the final sanding and smoothing, gradually switch to finer grits, such as 120 or 150, to achieve a polished result.
Material Composition
Sandpaper can be made of various materials, including aluminum oxide, silicon carbide, or garnet. Each material has its own advantages and is suitable for different applications. Aluminum oxide is a durable and versatile option suitable for most deck sanding tasks. Silicon carbide is ideal for sanding hard surfaces and removing tough finishes. Garnet sandpaper is commonly used for fine sanding and polishing. Consider the specific requirements of your deck and choose the sandpaper material that best suits your needs.
Additionally, sandpaper can come in either open-coat or closed-coat forms. Open-coat sandpaper has more space between the abrasive particles, making it less likely to clog. This type is ideal for rougher sanding tasks. Closed-coat sandpaper has a higher density of abrasive particles and provides a smoother finish. It is more suitable for final sanding and smoothing.
When buying sandpaper, look for options designed specifically for deck sanding or woodworking. These types of sandpaper are typically more durable and well-suited for handling the demands of outdoor projects.
Remember, using the right sandpaper is essential to achieve the desired results. Take your time to select the appropriate grit level and material composition for your deck sanding project, and you’ll be on your way to a beautifully restored deck.
Proper Sanding Techniques
When it comes to sanding your deck after pressure washing, using the proper techniques will ensure a smooth and even surface. Follow these steps to achieve the best results:
1. Choose the right sandpaper: Start with a coarse-grit sandpaper, such as 60 or 80 grit, to remove any stubborn dirt, stains, or old finish. Afterward, switch to a finer-grit sandpaper, such as 120 or 150 grit, for a smooth finish.
2. Sand along the grain: Always sand the deck boards in the direction of the grain to prevent any damage or splintering. Use long, even strokes, applying consistent pressure to achieve uniform results.
3. Sand in multiple passes: Start with the coarse-grit sandpaper and make multiple passes over the entire deck surface. Gradually switch to finer-grit sandpaper as the wood becomes smoother. Make sure to sand any hard-to-reach areas, such as corners or edges, to ensure a consistent appearance.
4. Check for smoothness: After sanding, run your hands over the deck surface to check for any rough spots or imperfections. If necessary, repeat the sanding process with a finer-grit sandpaper until the surface feels smooth to the touch.
5. Clean up thoroughly: Once you have finished sanding, use a broom or vacuum cleaner to remove any dust or debris from the deck. This will prepare the surface for the next step, whether it’s staining, sealing, or applying a new finish.
6. Protect yourself: Remember to wear protective gear, such as safety goggles, a dust mask, and gloves, to prevent any injuries or inhaling dust particles during the sanding process.
By following these proper sanding techniques, you can ensure that your deck is properly prepared for further treatment, resulting in a beautiful and long-lasting finish.
Dealing with Stubborn Stains
While pressure washing can remove a lot of dirt and grime from your deck, stubborn stains may require some additional measures to be effectively removed. Here are a few techniques you can try:
1. Scrubbing with a Stiff Bristle Brush
If there are oil stains or mold and mildew that are deeply embedded in the wood, using a stiff bristle brush can help loosen and remove them. Apply a deck cleaner or a mixture of water and oxygen bleach to the affected areas and scrub them vigorously with the brush. Be sure to follow the manufacturer’s instructions on the cleaner or bleach for the best results.
2. Using a Wood Brightener
If your deck has dark or discolored spots after pressure washing, a wood brightener can help restore its natural color. Apply the wood brightener according to the manufacturer’s instructions and allow it to sit for the recommended time before rinsing it off with water. This will help lighten the stains and revive the appearance of the wood.
If the stains persist after trying these methods, you may need to resort to sanding the deck. Sanding can help remove stubborn stains and provide a smooth surface for refinishing. However, sanding should be done carefully to avoid damaging the wood, and it can be a time-consuming task.
Before sanding, make sure to choose the right sandpaper grit for the job. Coarse grits, such as 40 or 60, are suitable for initial sanding to remove stains and rough spots. Finer grits, such as 120 or 150, can be used for final sanding to achieve a smooth finish.
Always sand in the direction of the wood grain and avoid applying too much pressure, as it can leave marks on the surface. Start with a small section and gradually work your way across the entire deck.
| Materials Needed: | Tools Needed: |
|---|---|
| – Deck cleaner | – Stiff bristle brush |
| – Water | – Wood brightener |
| – Oxygen bleach | – Sandpaper |
| – Sanding block or electric sander |
By following these steps and being patient, you can effectively deal with stubborn stains on your deck and achieve a clean and fresh-looking surface.
Finishing and Staining Your Deck
After you have finished the sanding process, it is important to properly finish and stain your deck to protect it from the elements and enhance its appearance. Here are the steps to follow:
- Clean the Surface: Before applying any finish or stain, make sure the surface is clean and free of any dust or debris. You can use a broom or a leaf blower to remove loose particles, and then wipe down the deck with a damp cloth.
- Choose the Right Finish: There are several types of finishes available for decks, including clear sealers, semi-transparent stains, and solid stains. Consider the look you want to achieve and the level of protection needed when selecting the finish.
- Test the Finish: Before applying the finish to the entire deck, it is advisable to test it on a small, inconspicuous area first. This will help you ensure that the finish will look the way you want and adhere properly to the wood.
- Apply the Finish: Using a brush, roller, or sprayer, apply the finish evenly to the deck boards, following the manufacturer’s instructions. Start from one end and work your way to the other, making sure to cover all the surfaces, including the sides of the boards.
- Allow the Finish to Dry: After applying the finish, allow it to dry completely before walking on the deck or replacing any furniture or plants. The drying time will vary depending on the type of finish and the weather conditions, so refer to the product label for guidance.
- Maintain the Finish: To keep your deck looking its best, it is important to regularly maintain the finish. This may involve reapplying the finish every few years or as needed, depending on the wear and tear the deck receives.
By following these steps, you can ensure that your deck is properly finished and protected, allowing you to enjoy its beauty and durability for years to come.
