Deck Stripping Guide: Prep, Remove Old Stain, and Refinish

When we bought our house, the deck was in rough shape. Before we could refresh it with a new coat of stain, we had to strip away 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 a first-timer.

That photo shows the result of the stripping step. If you want to see the deck after we applied a new stain, check the related tutorial we published on how to stain and seal a deck.

We also repaired a section where a tree had grown through the deck, so you may notice a patch of new wood in some images. If you need that fix, we have a separate patching guide.

Can I Skip the Stripping Step?

If you plan to restain or repaint a wood deck, removing the old finish provides the best, most durable bond for the new product. There are products designed to be applied over an existing coat—Rust-Oleum Restore and Behr DeckOver, for example—both create a thicker, paint-like layer over deck surfaces. We didn’t like the rough texture of Restore, and while DeckOver was smoother, it would have been costly and would not produce the traditional stained wood appearance we wanted. That’s why we chose to strip our deck first.

Can I Just Use a Pressure Washer?

Power washing can work well to remove dirt, mildew, and some finishes, especially when combined with chemical cleaners. We used a pressure washer to clean an outdoor shower previously, but for this deck we avoided it because the wood was soft and in places rotting. High-pressure water can damage deteriorated boards, and our goal was to extend the deck’s life a few years rather than accelerate its decline.

If your deck is in better condition, a pressure washer might be a good option—just follow a proper beginners’ guide for best results.

How to Strip Your Deck Yourself

Here’s a concise overview of the six steps we followed to remove the finish from our deck, porch, stairs, and railings. Depending on the deck size, this can be done in a day or over a weekend:

1. Ready your deck
2. Wet your landscaping
3. Apply deck stripper with a roller
4. Scrub off the old paint or stain
5. Neutralize the deck stripper
6. Enjoy your results

Tools & Supplies

These are the main materials we used:

1. Bucket – for pouring stripper to dip the roller
2. Protective gear – rubber gloves, goggles, and a mask
3. Stiff bristle brush with pole
4. Hose
5. 1/2″ nap paint roller with extension pole
6. Wood stain and finish stripper – we bought several bottles and used three
7. All-in-one wood cleaner
8. Pump sprayer – for applying the cleaner

Step 1: Ready Your Deck

Clear the deck of furniture and obstacles and check the weather so you can finish the job without rain interrupting. A cooler, cloudy day is best so the stripper doesn’t dry too quickly during application.

Step 2: Wet Your Landscaping

Rinse surrounding plants and beds with water to dilute any runoff. The stripping product we used is biodegradable and water-soluble, but it’s still wise to avoid high concentrations on vegetation.

Step 3: Apply the Deck Stripper with a Roller

Pour the stripper into a bucket or deep tray and apply it liberally with a roller. The product is thick—almost porridge-like—so it coats well without excessive dripping. Work methodically to cover every board and try to do so on a cloudy day; the instructions suggest letting it sit for 5–45 minutes without fully drying. If areas start to dry, lightly mist them with water to keep the stripper active.

Step 4: Scrub Off the Old Paint or Stain

After the stripper lifts the finish, use a stiff-bristled brush to scrub the surface. The lifted finish comes off as a brownish sludge; rinsing reveals the wood grain beneath. Attaching the hose to the brush so you can scrub and rinse simultaneously sped up the work. The first pass took about 45 minutes on our large deck, and we followed with spot scrubbing and multiple rinses until the surface looked clean.

Step 5: Neutralize the Deck Stripper

Apply a deck cleaner/brightener to neutralize the stripper and brighten the wood. We used a 1:1 mix of cleaner and water in a pump sprayer, applied it across the deck, let it sit a few minutes, then scrubbed and rinsed thoroughly. This step ensures any residual chemical is removed and improves the wood’s appearance before staining.

Step 6: Enjoy Your Results

The stripped deck looked dramatically better: much of the weathering and peeling finish was gone and the wood appeared almost like new, albeit lighter. The results blended well with the replacement boards where we repaired tree damage. The entire stripping process for our portion took roughly 3.5 hours; we completed the remaining section the next day.

Our plan was to finish with a semi-transparent stain close to the previous rich brown so the whole deck would look cohesive; we left some vertical railings unstripped because they were in better condition and their color matched well. The end result of the stain is available in our follow-up post.

In short: even a rough, weathered deck can often be saved with some elbow grease and the right process. Stripping, neutralizing, and then refinishing gave our deck new life and prepared it for staining.
