Best Practices for Finishing a Sanded Deck

Finishing a sanded deck is a crucial step in ensuring a long-lasting and beautiful outdoor space. A well-finished deck not only enhances the aesthetic appeal of your home, but also protects the wood from the elements, extends its lifespan, and improves safety. When it comes to finishing a sanded deck, choosing the right type of finish is essential. In this article, we will delve into the best practices for finishing a sanded deck, including choosing the correct grit size, types of decking finishes, and tips for achieving an even finish.
The Importance of Correct Grit Size, Best way to sand a deck
The type of grit size you use to sand your deck plays a critical role in the final finish. Coarse grits (about 80-100) are used for heavy-duty sanding and removing old finishes, while finer grits (120-150) are used for smoothing out the wood. It’s essential to transition from coarse to fine grits in stages to ensure a smooth finish. Skipping this step can result in a finish that is either too rough or too smooth, which can affect the appearance and durability of the deck.
To achieve a smooth finish on your deck, it’s essential to sand with the right technique, using a combination of coarse and fine-grit sandpaper to remove old finishes and even out the wood grain. Just like finding the perfect lash shape can make all the difference in a successful lash extension application – check out this guide to determine the ideal size for mega volume lash extensions – the right sanding sequence can make or break the appearance of your deck, so don’t skip this crucial step.
Types of Decking Finishes
When it comes to choosing a decking finish, you have several options, including oil-based and water-based stains. Oil-based stains provide a rich, deep color and are more durable than water-based stains. However, they take longer to dry and have stronger fumes. Water-based stains, on the other hand, are easier to clean up and dry faster than oil-based stains. They also have a lower VOC (volatile organic compound) content, making them a more eco-friendly option.
When it comes to sanding a deck, it’s all about finding the right rhythm, much like a perfectly aligned swing in golf, but to master that requires the right best practice golf balls – and by analogy, the right grit sandpaper to tackle your deck’s unique finish, from cedar to pressure-treated, requiring patience and finesse to achieve a seamless finish, like a smooth golf swing.
Tips for Achieving an Even Finish
Achieving an even finish on a deck requires patience, planning, and attention to detail. Here are three tips to help you achieve a beautiful, even finish:
- Start by cleaning the deck thoroughly to remove any dirt, debris, or old finishes. This will ensure a smooth finish and prevent any imperfections from showing.
- Use a high-quality brush or roller to apply the finish, working in sections to maintain even coverage.
- Apply thin coats, allowing each coat to dry completely before applying the next. This will help prevent drips and unevenness.
Working with Oil-Based Stains
Oil-based stains can be a bit more challenging to work with than water-based stains, but with the right techniques, you can achieve a beautiful, even finish. Here are some additional tips to keep in mind when working with oil-based stains:
- Make sure the deck is completely dry and free of dust and debris before starting.
- Use a high-quality brush or roller to apply the stain, working in sections to maintain even coverage.
- Apply thin coats, allowing each coat to dry completely before applying the next. This will help prevent drips and unevenness.
Working with Water-Based Stains
Water-based stains are generally easier to work with than oil-based stains, but they still require some care to achieve an even finish. Here are some additional tips to keep in mind when working with water-based stains:
- Make sure the deck is completely dry and free of dust and debris before starting.
- Use a high-quality brush or roller to apply the stain, working in sections to maintain even coverage.
- Apply thin coats, allowing each coat to dry completely before applying the next. This will help prevent drips and unevenness.
Common Mistakes to Avoid
While finishing a sanded deck can be a rewarding process, there are several common mistakes to avoid to ensure a beautiful, even finish. Here are a few to keep in mind:
- Not taking the time to properly prepare the deck before finishing.
- Not using high-quality materials and tools, such as a high-quality brush or roller.
- Not following the manufacturer’s instructions for the finish.
By following these best practices for finishing a sanded deck, you can achieve a beautiful, even finish that will last for years to come.

Common Queries
What’s the best grit size for sanding a deck?
The ideal grit size for sanding a deck depends on the type of wood and the level of smoothness desired. Typically, for wood with a lot of texture, a coarse grit size (about 80-100) is recommended, while for smoother finishes, a finer grit size (about 120-150) is preferred.
Can I use a belt sander for sanding a deck?
While belt sanders can be effective for sanding small areas or specific features on a deck, they might not be the best choice for larger projects. Belt sanders can create uneven surfaces, and their aggressive sanding action can damage certain types of wood. Instead, opt for an orbital sander or a drum sander for more efficient and controlled sanding.
How do I choose the right type of sandpaper for my deck?
The type of sandpaper needed depends on the type of wood and the desired finish. For pressure-treated wood, look for sandpaper specifically designed for hardwoods or treated woods, which often feature a durable mesh and resin-bonded grits. For softer woods, use sandpaper with a finer grit and a softer bond, which will help prevent scratches and tearing.
Can I sand a deck in the rain or wet conditions?
No, it’s essential to sand a deck when the wood is dry, as sanding in wet conditions can lead to uneven finishes, scratches, and damage to the wood.
How long does it take to sand a deck?
The time required to sand a deck depends on its size, the type of wood, and the level of smoothness desired. Typically, for a small deck, sanding can take anywhere from a few hours to a full day, while larger decks can require several days to complete.
Can I use a power washer to clean a deck before sanding?
No, power washers can damage the wood, strip away the finish, and potentially harm surrounding plants. Instead, use a gentle cleaning solution and a soft-bristled brush to clean the deck before sanding.
