How to Stain a Deck

Step 1: Prep for Deck Staining

Preparation is critical when staining a deck. Here are a few scenarios to guide you.

New/Treated: Decks are often built from new pressure-treated wood. While treated lumber is protected from the elements, it is generally too wet to stain right away. Some woods may also have a glossy sheen known as a mill glaze, which must be “broken” or removed. To determine if your wood is too wet or has a mill glaze, sprinkle it with water. If the water beads on the surface, the wood is not ready to accept stain. If the wood absorbs the water quickly, it’s ready for stain after a quick cleaning with Woodluxe All-in-One Wood Cleaner.

To break the mill glaze, apply Woodluxe Wood Brightener & Neutralizer to the wood and scrub thoroughly. Once the wood is completely scrubbed down, use a hose or power washer to remove the product. Let the wood dry for at least 48 hours, then sand everything down with 80-grit sandpaper.

Prep Weathered Wood for Deck Staining

Weathered Wood: Woodluxe Wood Restorer is our go-to product for grayed-out decks. Use Wood Restorer with a stiff brush to clean the wood and remove loose, dead fibers. Afterward, rinse the deck and treat the wood with Woodluxe Wood Brightener & Neutralizer. Once the wood is completely scrubbed down, use a hose or power washer to remove the product. Let the wood dry for at least 48 hours, then sand with 80-grit sandpaper.

Flaking or Peeling: If you have a previously stained deck that is peeling or flaking, try power washing, wire brushing, or sanding to remove as much of the loose, peeling stain as possible. For anything that remains, use Woodluxe Wood Stain Remover to help remove the remaining stain. Afterward, rinse the deck and treat the wood with Woodluxe Wood Brightener & Neutralizer, then sand the deck to ensure a smooth surface for staining.

After letting the wood dry for 48 hours, check the weather: Rain-free days are best for applying stain. If the forecast is dry for at least 36 hours, you’re ready to stain the deck.

Step 2: Test Your Deck Stain Color Choices

Our Woodluxe 8 oz. Stain Samples are the best way to determine which wood stain opacity and color is right for your deck. Our experts can help you with the options and even let you know how much stain to buy. Visit your locally owned Benjamin Moore store today to buy a sample and try before purchasing gallons.

Once you decide on a selection of colors and opacities, test the stains in an inconspicuous spot or on a spare piece of lumber that matches the wood used on your deck to give yourself a preview of how each will look on the finished deck.

Step 3: Stain the Deck

Deck stain can be applied multiple ways, although the tried-and-true method is by brush. You can also use a standard paint roller or a stain pad to apply stain to the wood. It is always best to follow these applications with a brush to help work the stain into the wood.

To prevent lap marks, follow the direction of the wood grain, staining a few full boards at a time. Lap marks can also occur if the stain dries too quickly, so avoid working in direct sunlight if you can. Plan to stain at a time of day when the area is in the shade.

Step 4: Let the Deck Stain Dry

Your newly stained deck will take about 48 hours to fully dry, so we recommend waiting a minimum of two days before opening it up to foot traffic.
