How to Refinish Your Weathered Deck in a Weekend (Even If You're a Beginner)

Skip the $2,000 contractor quote. Here's how to make your old deck look brand new with the right tools.

Let's be honest: a gray, splintered deck is an eyesore. It's also a safety hazard and a sign that your home's curb appeal is taking a hit.

But here's the good news: you can refinish your entire deck in one weekend. No pro skills required. Just the right tools and a little patience.

I just did mine. Here's exactly how.

What You'll Need

Before you start, grab these tools. Trust me, they'll save you hours of elbow grease.

�� Pro tip: Get a paint sprayer with adjustable flow control. It'll save you from over-spraying and wasting expensive stain.

Step 1: Clear the Deck (Literally)

Move all furniture, planters, and grills off the deck. Sweep away leaves and debris.

Estimated time: 15 minutes

Step 2: Deep Clean with a Pressure Washer

This is where the magic starts.

Attach the 25-degree nozzle to your pressure washer (keep it about 6-8 inches from the wood). Work in long, sweeping strokes with the grain of the wood.

⚠️ Don't use the 0-degree nozzle – it'll gouge the wood.

Let the deck dry for 24-48 hours before moving to the next step. You want the wood to be dry to the touch.

Estimated time: 1-2 hours (plus drying time)

Step 3: Sand Away Rough Spots

After washing, you'll notice raised wood fibers and rough patches.

Use an orbital sander with 80-grit sandpaper for the main deck surface. For edges and corners, switch to 120-grit.

�� Why this matters: Sanding opens up the wood pores so the stain absorbs evenly. Skip this step and your finish will peel in 6 months.

Vacuum up all the dust when you're done.

Estimated time: 2-3 hours (for a 400 sq ft deck)

Step 4: Mask Off Everything You Don't Want Painted

Tape off your siding, doors, and any nearby plants (cover them with drop cloths). Trust me, overspray is real.

Estimated time: 30-45 minutes

Step 5: Spray the Stain with a Paint Sprayer

Here's where you save the most time.

Load your HVLP paint sprayer with deck stain (look for "sprayable" on the label). Adjust the flow control to a medium setting – you want good coverage without drips.

Technique:

Hold the gun 6-8 inches from the wood

Spray in steady, overlapping passes

Work in small sections (4x4 feet at a time)

Back-brush if needed: use a brush to work the stain into gaps after spraying

Estimated time: 1-2 hours (compared to 6-8 hours with a brush)

Step 6: Let It Dry and Enjoy

Most stains dry to the touch in 2-4 hours, but wait 24 hours before moving furniture back.

Step back and admire your work. That gray, tired deck is now rich, protected, and ready for summer barbecues.

Why This Tool Combo Works

Total time saved: At least 10 hours of manual labor.

One Last Tip

Your deck doesn't need to be perfect. It needs to be done.

Don't wait until the wood starts cracking and rotting. A weekend of work now saves you thousands in replacement costs later.

Grab your tools. Spray that stain. And enjoy your weekend. ☀️
