How to Strip a Deck Before Staining

When we bought our house, the deck was in rough shape. Before we could revive it with a fresh coat of stain, we needed to strip off the old finish first. It took time and effort—our deck is nearly 700 sq. ft.—but it was a totally doable weekend project, even for first-timers.

That photo shows the stripping before-and-after. For the finished look after staining and sealing, see our separate tutorial on how we stained and sealed the deck.

Ignore the patch of new wood in some photos—there was a section where a tree had grown through the deck and we had to repair it. We also documented how to patch a deck if you need guidance.

Can I Skip the Stripping Step?

If you plan to restain or repaint a wood deck, removing the old finish gives a better, longer-lasting bond. Some products are formulated to go over existing coatings and create a thick, paint-like layer. We tested options and decided against them for two reasons: first, the texture and thickness didn’t match the traditional stained wood look we wanted; second, the cost would have been higher. For a classic stained finish, stripping was the right choice.

Can I Just Use a Pressure Washer?

Power washing can be an effective way to strip paint or stain, especially when used with chemical cleaners. We’ve used a pressure washer to clean other wood structures, removing dirt and mildew without chemicals. For this particular deck, however, the wood was very worn and soft in places. We worried that pressurized water would damage fragile boards, so we chose a chemical stripper plus scrubbing instead. If your deck is sound, power washing is worth considering; if it’s rotting or soft, avoid high pressure to prevent further damage.

How to Strip Your Deck Yourself

Here’s a concise six-step overview of the process to strip the finish off a deck, porch, stairs, or railings. Depending on deck size, it can often be completed in a day or over a weekend.

1. Prepare the deck and plan the work.
2. Protect surrounding landscaping.
3. Apply a deck stripper with a roller.
4. Scrub off the old paint or stain.
5. Neutralize the stripper with a deck cleaner.
6. Rinse and enjoy the refreshed wood.

Tools & Supplies

These are the materials we used to strip our deck:

1. Bucket – for pouring stripper and dipping the roller.
2. Protective gear – rubber gloves, goggles, and a mask; the chemicals have strong fumes.
3. Stiff-bristle brush with a pole for scrubbing.
4. Garden hose for rinsing and wetting plants.
5. 1/2″ nap paint roller with extension pole to apply the stripper.
6. Wood stain and finish stripper – we purchased multiple bottles and used what we needed.
7. All-in-one wood cleaner to neutralize the stripper and brighten the wood.
8. Pump sprayer for applying the cleaner across larger areas.

Step 1: Ready Your Deck

Clear furniture and obstacles and check weather forecasts. Choose a cooler, cloudy day if possible so the stripper won’t dry too quickly during application. Make sure you have enough uninterrupted time to apply and scrub the entire surface.

Step 2: Wet Your Landscaping

Before you start, thoroughly water any nearby plants to dilute and protect them from runoff. Even if a product is biodegradable, preventing concentrated drips on shrubs and flowers is a good precaution.

Step 3: Apply the Stripper with a Roller

Pour the stripper into a bucket or tray and saturate your roller. The stripper is thick and spreads easily—thick enough not to drip excessively, but fluid enough to cover boards. Work methodically, coating each board liberally. The product directions typically recommend letting the stripper sit for 5–45 minutes without allowing it to fully dry; mist any drying spots with water to keep the stripper active.

Step 4: Scrub Off the Old Finish

Once the finish begins to lift, use a stiff-bristled brush to scrub the boards. This takes some elbow grease, but most boards clean up with a few firm strokes. The removed finish often appears as a brown sludge; rinsing reveals the wood grain beneath. Attaching your hose to a brush head lets you scrub and rinse simultaneously, which speeds up the process. Expect scrubbing to be the most time-consuming part—plan for multiple passes and rinses.

Step 5: Neutralize the Stripper

After scrubbing and rinsing, apply a deck cleaner/brightener diluted with water to neutralize the stripper and brighten the wood. We used a pump sprayer filled with a 1:1 ratio of cleaner to water. Let it sit briefly, then follow the product directions—many recommend scrubbing the cleaner into the wood for better results. Finish with a thorough rinse to remove any residue.

Step 6: Enjoy Your Results

The transformation is dramatic. Stripping removed peeling paint and much of the gray weathering, revealing fresher, bleached-looking wood. It blended well with the small new section we had to replace. The entire stripping process took about 3.5 hours for our first section; we completed the rest the next day. Working in sections can make the project more manageable.

Our plan is to use a semi-transparent stain similar in color to the deck’s original rich brown so the new and older boards blend together. We didn’t fully strip the small vertical railings because they were in better condition and their color still worked with our vision.

If your deck looks rough, proper stripping plus some hard work can extend its life and dramatically improve its appearance. Once the surface is stripped and neutralized, you’re ready to stain and seal for a refreshed, protected finish.
