How to Stain a Deck (Step-by-Step Guide for Lasting Beauty)

Key Takeaways

  • The exact steps for cleaning, prepping, and staining a wood deck so the finish lasts.

  • How to choose between transparent, semi-transparent, and solid stains.

  • Pro tips to avoid common mistakes and when it makes sense to hire a professional.

A freshly stained deck does more than refresh color—it shields the wood from moisture, sun damage, and everyday wear. Here in Southern Oregon’s Rogue Valley, wet winters, hot summers, and heavy UV exposure can quickly fade and crack untreated cedar, redwood, and pressure-treated lumber. Following the right process is the key to a finish that looks great and protects your investment for years.

Here’s how a DIY(er) can do a professional deck staining job.

1: Inspect and Prepare the Deck

Before you start staining, give the deck a thorough inspection.

Check for Damage

Look for loose boards, popped nails, or rot. Stain can’t fix structural problems, so repair these first.

Clear the Space

Remove furniture, planters, and rugs, then sweep away leaves and debris. A clean surface helps every other step go smoothly.

2: Clean the Wood

A spotless surface ensures even stain penetration.

Pressure or Soft Washing

Perform a low-pressure, deck pressure washing or soft washing technique to remove moss, algae, and grime. Keep the nozzle moving to avoid gouging softer woods like cedar.

Wood Cleaner for Stubborn Spots

If mildew or heavy pollen lingers, apply a deck-safe cleaner and rinse thoroughly. Allow the deck to dry 24–48 hours, longer if the humidity is high.

3: Sand for a Smooth Finish

Light sanding opens the grain and removes any raised fibers.

  • Use 80–100-grit sandpaper and/or a power sander.

  • Pay special attention to railings and high-traffic boards for a splinter-free surface.

4: Choose the Right Stain

Your stain choice affects both appearance and durability.

Transparent Stains

Highlight the wood’s natural grain but provide the least UV protection—best for newer decks in shaded spots.

Semi-Transparent Stains

Balance color with visible grain. A popular pick for cedar and redwood, they offer stronger sun protection while showcasing natural beauty.

Solid (Opaque) Stains

Deliver the strongest UV defense and can hide older discoloration. Ideal when you want bold, uniform color.

5: Apply the Stain

Plan for a dry day with temperatures between 50–80 °F.

  • Use a high-quality brush or pad applicator for even coverage.

  • Work with the grain, coating two or three boards at a time to prevent lap marks.

  • Apply a second coat only if the product recommends it.

6: Let It Cure

Allow the deck to dry at least 24 hours before replacing furniture or walking on it. Always follow the drying times listed on the stain can; cool, damp weather may require longer.
