How to Repair and Paint Exterior Stairs (Weekend DIY)

7 Steps To Repairing & Painting Your Stairs

Our exterior stairs were in rough shape. When I first painted them two years ago with Cabot Deck Correct, I had high hopes it promised to fill cracks, lock down splinters, and resist dirt.

But instead, the paint sank into the wood, didn’t cover imperfections, and was impossible to keep clean. The risers were still peeling, and every time I used the stairs, I cringed.

What I Used

Tools

Materials

1. Scraping Off the Old Paint

The first step was to remove the peeling paint from the surface. Using a paint scraper, I carefully scraped away the loose and flaky paint. Some areas were cracked, but not enough to come off with the paint scraper. It’s important to get as smooth a surface as possible, for the new paint to adhere properly. This tool helps scrap the paint quickly, but works best with a new blade. Otherwise, you are basically just sanding down the existing paint.

2. Sealing the Edges

First I caulked the area where the wood met the concrete. It wasn’t easy to get a straight line of caulk, especially on the areas of wood that needed repair. In retrospect, I should have saved this for the final step. Getting a straight line would have been easier to achieve and to prevent debris getting into the caulk before it dried. The bottom riser was really rough from moisture seeping in and causing the paint to peel.

3. Repairing Cracks and Holes In The Exterior Stair Risers

Next, I used Bondo All-Purpose Putty to fill in all the cracks. This product is excellent for filling and smoothing imperfections on wood and concrete. After the Bondo dried, I sanded it down for a seamless finish. At first, I tried hand sanding with a sanding sponge, but it wasn’t effective. I switched to an orbital sander. I started with 60-grit sandpaper to smooth the rough areas. Then, I gradually worked up to 220-grit for a smooth finish, ready for paint.

4. Cleaning and Prepping the Area

After sanding, I vacuumed and wiped the steps with a wet rag to remove all dust. Don’t try this on a windy day.

5. Taping Off the Treads

I wanted to paint the risers, banister, railings, columns, and front door trim white. So, I carefully taped off the gray stair treads to keep everything clean and crisp. I used painters tape specifically for rough surfaces, which did exactly what it promised.

6. Priming the Surface

Finally up to Painting! I applied a coat of Kilz White Interior/Exterior Primer. After the first coat dried, I lightly sanded the surface to smooth out any imperfections before applying the second coat.

7. Painting the Exterior Stairs and Exterior Door Frame

For the final color, I used BEHR PREMIUM Ultra Pure White Porch and Patio Floor Paint in a low-lustre finish. I applied it to the risers and trim. I applied two coats, which it needed to cover the areas I had repaired with Bondo.

Final Reveal

Swipe to see the transformation! Proof that a little elbow grease (and the right tools) can make a huge difference.

Key Tips for Painting Exterior Stairs

BEHR PREMIUM Porch and Patio Floor Paint Enamel is an interior and exterior floor coating for concrete and wood surfaces. This durable 100% acrylic latex finish resists mildew, scuffing, fading, cracking and peeling. Ideal for use on porches, floors, decks, basements and patios.

If you’re tackling a similar project, I recommend porch and patio floor paint. I used BEHR, it’s durable, resists dirt and has a low-luster finish making it perfect for high-traffic areas like front steps.

Prep: Sanding, cleaning, and priming are the most important steps if you want a long-lasting finish.
Quality Products: Invest in an exterior paint designed for wood steps and outdoor use.
Seal: Don’t skip sealing gaps between the wood and walkway to protect against moisture damage.
Be Patient: Allow each layer (primer and paint) to dry fully before applying the next, or you can risk it all peeling off.

FAQ: Repairing

How do I check for rotting wood on my exterior steps?

Inspect the steps closely for soft spots, discoloration, or crumbling areas. Use a screwdriver to gently press into the wood; if it sinks easily, the wood may be rotting.

Can I paint over wood that has started to rot?

No, painting over rotting wood won’t fix the issue. You need to remove the rotted sections. Then, fill the area with wood filler or epoxy. Alternatively, replace the wood entirely. This ensures structural integrity before painting.

What should I do if a large section of my exterior steps is rotting?

For extensive rot, it’s best to replace the damaged boards entirely. If the rot has compromised the structure of the steps, consult a professional for repairs. Once replaced, seal the new wood properly before painting.

How can I prevent wood rot on exterior steps in the future?

Seal gaps where the wood meets concrete to prevent moisture infiltration. Use a high-quality exterior primer and paint, and apply a water-resistant sealer to protect the wood from weather and humidity.

FAQ: Painting

How do I protect my painted exterior steps from stains and wear?

Seal the painted steps with a clear topcoat, such as a polyurethane or polycrylic sealer designed for exterior use. This adds an extra layer of protection against dirt, stains, and weather.

How long does it take to repaint exterior steps?

The process typically takes 3–5 days, including prep work, drying time between coats of primer and paint, and applying a sealer. Plan for a long weekend to complete the project.

Can I paint over existing paint without removing it?

If the existing paint is in good condition, you can paint over it. However, if it’s peeling or cracking, it must be removed to create a smooth surface for the new paint to adhere properly.

Lessons Learned While Repainting My Front Porch Steps

Honestly, this whole process reminded me that a little extra effort can make a huge difference. It wasn’t the most glamorous weekend. At one point, I had dust in my hair, paint on my face, and Bondo under my nails. But I’m no longer cringing every time I walk up to my front door.

If you’re thinking about repainting your exterior steps, take it from me: do the prep work.
