Frequently Asked Questions
Do I really need to sand my deck before applying a new coat of stain?
Yes, you should. Sanding removes the dead wood fibers and opens up the pores of the lumber, which allows the stain to soak in properly. If you skip this step, the new stain will likely peel off within a few months. Think of sanding as the essential foundation work for a long-lasting finish.
What grit sandpaper should I start with for an old deck?
Start with 60 to 80 grit paper if the wood is rough or has peeling paint. This is coarse enough to level out the surface without removing too much material. Once you have smoothed the boards, move up to 100 or 120 grit for a final polish. This ensures the wood feels smooth to the touch and looks professional.
Is it better to use a belt sander or an orbital sander?
Use an orbital sander for almost every deck project. Belt sanders are incredibly powerful, but they are very easy to misuse, often leaving deep, permanent gouges in your deck boards. Orbital sanders are much more forgiving for beginners. They provide a smooth, uniform finish that is far less likely to show mistakes.
How often should I empty the dust bag?
You should empty the bag or canister when it is half full. Keeping the bag empty maintains the airflow needed for the vacuum system to work effectively. If you let the bag fill up completely, the dust will stay on the deck surface. This creates a gritty barrier that can actually scratch the wood while you are trying to sand it.
Can I use a sander on composite decking?
You generally should not sand composite decking because it can melt the plastic components and ruin the factory texture. If you have stains or minor scratches on composite, it is better to use a deck cleaner. Only use a sander on composite if the manufacturer specifically states it is safe. Otherwise, you risk turning a small blemish into a permanent, smooth patch that stands out against the rest of the grain.
