First, staining a wood deck is a very important step in protecting the wood and allowing your deck to last longer. Once you have stained it initially, your wood deck will need to be stained roughly every two years. Whether you will need to stain it sooner or can wait a bit will depend on sun exposure, climate, and how the weather has been in your area.
How can you tell if it is time to seal your deck?
There is a simple water test that you can do. Sprinkle some water on your deck. If it beads up then your deck can wait, however, if the water is quickly absorbed into the wood, then your deck needs to be stained.
Before staining your deck, you will want to clean it, as you do not want to trap dirt, mildew, other things against the wood, as this can damage your deck.
To clean your deck you will first want to clear any objects off the deck, the sweep off dirt and debris and be sure to clean between the cracks of the boards. If you notice any rough spots or splintered areas on your deck go ahead and sand those down with 80 grit-sand paper before sweeping. Next you will want to get some deck cleaner, be sure you read the instructions, some cleaners can be used with
garden sprayers, others will need to be applied with a
paint roller or other method. Also take precautions to protect any exposed plants around your deck, as the cleaner could damage them.
Follow the instructions on your deck cleaner to finish the cleaning process.
Now you will need allow your deck to dry for about 2 days. During this time you may want to go ahead and choose the stain or sealer that you will be using. When choosing a stain or sealer be sure to choose one that is designed to repel water, resist mildew, and prevent fading. You can choose between oil based and water based stains. However, keep in mind that oil based finishes require less upkeep than water based finishes.

When applying a sealer or stain, always read the manufacturer's directions. Drying times differ based on air temperature and humidity. Before you start, check the boards for needed repairs such as split boards or popped-up nails.
Wear rubber gloves, close-toed shoes, a long-sleeved shirt and pants when applying finish or cleaner to minimize the chance of skin irritation. Also, wear safety glasses to protect your eyes from back spray.
- Check the weather. Try to find at least two days of dry weather with temperatures between 50°F and 90°F.
- Remove all deck furniture and plants.
- Sand all grade stamps, marks, and splintered areas. The entire deck may require sanding with a pole sander or palm sander to speed up the process. Sand in the direction of the grain. Be sure to wear a safety mask so you won't inhale the sawdust.
- Sweep off loose debris and clean between the cracks. Make sure the deck is dry.
- Cover plants and shrubs with clear plastic.
- Stir the sealer or stain thoroughly. Don't shake sealer. Bubbles will form in the finish.
- Apply a thin, even coat of sealer or stain over a two- to three-board section with a paint roller with an extension handle or a sprayer. Two thin coats are better than one thick coat that doesn't properly adhere or dry.
Don't allow the finish to puddle. To speed up the process, one person can apply the stain or sealer and another person can use a roller or broom to spread puddles and to work the finish into the wood, a process known as back-rolling.
- Repeat the above process for the entire deck. Use a paintbrush to apply the sealer / stain in corners and other difficult areas, such as steps, railings, end grain and cracks. A second coat is optional.
- Allow the deck to dry completely.
- Before disposing of rags, spread them out to dry completely. Heat generated from evaporating finish on a pile of rags can start a flash fire. If you're using latex stain, clean equipment with soapy water. If you're using oil-based sealers, clean with paint thinner or mineral spirits.
- Rinse the plastic covering the plants with a hose and remove it.
TIPS:
- Don't apply deck product in direct sun. The finish will dry too quickly and won't absorb into the wood.
- Use the water test to check your deck every few months to ensure the sealer is repelling water.
- Regularly sweep off debris.
