How to Prep Your Deck for Staining After Power Washing
A freshly stained deck can completely transform your outdoor space—but the key to a long-lasting finish starts with the prep. If you’ve already tackled power washing, you’re off to a great start. But before you crack open that can of stain, there are a few critical steps to ensure your deck absorbs the stain evenly and looks great for seasons to come.
In this post, we’ll walk you through exactly how to prep your deck for staining after power washing. Whether you're tackling the project yourself or just want to better understand the process before hiring help, these tips will help you make the most of your deck restoration efforts.
1. Let Your Deck Dry Completely
After power washing, your deck is soaked—and staining too soon is one of the most common mistakes homeowners make. Why? Because wet wood won’t absorb stain properly. It’ll sit on the surface, creating a blotchy finish that won’t last.
Here’s how to tell when your deck is ready:
Wait at least 48 hours, longer if it’s humid or shaded.
Do a moisture test by dripping a few drops of water on the surface. If it beads up, the wood’s still too wet. If it soaks in, you’re good to go.
In Massillon, Ohio, where summer humidity can hang around, it’s smart to wait at least 72 hours before staining.
2. Sand Down Rough Patches
Power washing blasts away grime, but it can also raise the wood grain and leave behind splinters. Once your deck is dry, inspect it closely. Run your hand along the surface—you’ll likely find rough patches, especially near knots or heavily weathered areas.
Use a pole sander or palm sander with 60- to 80-grit sandpaper to smooth the surface. Focus on:
High-traffic areas like steps and handrails
Spots where the grain feels lifted
Anywhere that looks fuzzy or splintered
This not only improves appearance but also helps the stain soak in more evenly.
3. Clean Off Dust and Debris
Sanding creates fine sawdust, and even a little bit left behind can ruin your stain job. Before staining:
Sweep the deck thoroughly
Use a leaf blower or shop vac to remove dust from corners and cracks
Wipe down the surface with a damp cloth if needed (then let it dry again)
This step ensures the stain bonds directly with the wood, not a layer of grime or particles.
4. Inspect and Repair the Deck
Now’s the perfect time to check for loose nails, popped screws, or damaged boards. Use a hammer or drill to secure any fasteners that have backed out. If a board is rotting or cracked, replace it before staining.
Also, pay attention to gaps between boards. Small gaps are normal, but if you spot significant warping or shifting, it might be time to bring in the pros for a more thorough assessment.
5. Choose the Right Day to Stain
Weather plays a huge role in how your stain sets. For best results:
Choose a dry day with temps between 50°F and 85°F
Avoid staining in direct midday sun—early morning or late afternoon is ideal
Check the forecast for at least 48 hours of dry weather after staining
Too hot, too cold, or too humid? You risk tacky surfaces, poor absorption, or uneven color.
