How to Strip a Deck for Staining and Remove Old Finish

When we bought our house, the deck was in rough shape. Before we could refinish it with a fresh coat of stain, we had to remove the old finish first. It took time and effort—our deck is nearly 700 sq. ft.—but it was a manageable weekend project even for a first-timer.

That photo shows the stripping before-and-after. If you want to see the finished result with stain and sealer applied, look for our How To Stain & Seal A Deck tutorial on the site.

We also repaired a small section where a tree had grown through the deck; we have a guide on Patching a Wood Deck if you need help with that kind of repair.

Can I Skip The Stripping Step?

For the longest-lasting outcome when restaining or repainting a wood deck, removing the old finish is recommended so the new coating bonds properly. There are products designed to go over existing finishes—such as thick coatings that create a paint-like covering—but they produce a different, often plastic-like texture and can be costly. We wanted a traditional stained wood look, so we chose to strip our deck first.

Can I Just Use a Pressure Washer?

Power washing can be an effective way to remove loose paint, dirt, mildew, and even some stain when combined with chemical cleaners. We used a pressure washer to clean our outdoor shower, but for this deck we decided against it because the wood was soft and partially rotted in places. High-pressure water can damage fragile boards, and our goal was to extend the deck’s life for a few more years rather than accelerate deterioration.

If your deck boards are solid and healthy, a pressure washer is worth considering; otherwise, a chemical stripper with careful scrubbing is usually safer.

How To Strip Your Deck Yourself

Here’s a concise overview of the six main steps to strip the finish from a deck, porch, stairs, or railings. Depending on size, the work can often be completed in a day or over a weekend.

1. Ready Your Deck
2. Wet Your Landscaping
3. Apply Stripper with a Roller
4. Scrub Off the Old Paint or Stain
5. Neutralize the Stripper
6. Enjoy the Results

Tools & Supplies To Strip Your Deck

Materials we used to remove the old finish:

1. Bucket – for the stripper, making it easy to load a roller
2. Protective gear – rubber gloves, goggles, and a respirator or mask (strippers often have strong odors)
3. Stiff bristle brush with pole – for scrubbing the finish off
4. Hose – for rinsing
5. 1/2″ nap paint roller with extension pole – to apply the stripper evenly
6. Wood stain & finish stripper – we used several bottles; the amount needed depends on deck size and how thick the existing finish is
7. All-in-one wood cleaner/brightener – to neutralize the stripper and brighten the wood
8. Pump sprayer – handy for applying cleaner and rinsing

Step 1: Ready Your Deck

Clear all furniture and obstacles so you can access every board. Check the weather: you’ll want enough dry time to complete a full section without rain, and a cool, cloudy day is ideal to prevent the stripper from drying too quickly.

Step 2: Wet Your Landscaping

Wet nearby plants and soil with a hose before you start to reduce potential harm from runoff. Many modern strippers are labeled biodegradable and rinse clean with water, but it’s still a good precaution to protect sensitive landscaping.

Step 3: Apply Your Deck Stripper With A Roller

Pour the stripper into a bucket or deep tray and saturate a roller. The product we used was thick—almost porridge-like—which made it easy to control and apply without excessive dripping. Work methodically and coat every board; the instructions will usually recommend letting the stripper sit anywhere from 5 to 45 minutes without letting it fully dry.

If the stripper begins to dry before you’re ready to scrub, lightly mist the surface with water to keep it active. Be aware the treated surface will be slippery; that slipperiness often means the finish is lifting.

Step 4: Scrub Off The Old Paint Or Stain

After the stripper has had time to work, use a stiff-bristled brush on a pole to scrub the finish off. The lifted finish often comes away in a brownish sludge that rinses clean. Applying water through a brush with a hose attachment lets you scrub and rinse as you go, which speeds the process and helps you see your progress.

Scrubbing took the longest: our first pass was about 45 minutes, followed by spot scrubbing and several rinses until the surface looked clean and the wood grain reappeared.

Step 5: Neutralize The Deck Stripper

Apply a deck cleaner or brightener to neutralize any residual chemical and to brighten the wood. We used a pump sprayer filled with a 1:1 mix of water and cleaner and followed the product directions. After the cleaner sat for a few minutes, scrub the deck again where instructed and then rinse thoroughly.

Step 6: Enjoy Your Results!

We were impressed with how much the stripping removed—not only the peeling coating but a lot of the gray weathering as well. The deck looked almost like fresh, bleached wood and blended well with the new boards we had to install where a tree was removed.

Here’s another before-and-after so you can see the difference the stripping made even before staining.

The main stripping session took about 3.5 hours and left us tired but satisfied. We worked in two sections over consecutive days to make the task more manageable. There’s a visible line where the completed area meets the untouched wood, which makes the improvement easy to spot.

Next we plan to apply a semi-transparent stain close to the original rich brown to help the newly stripped wood blend with the vertical railings, which we left as-is because they were in much better condition.

Update: We documented the finished stained deck in a follow-up post.

In short: even a weathered deck can often be refreshed with the right stripper, some patience, and elbow grease. The process saved our deck for a few more years and left us one step away from a much nicer finished look once stained.
