How to Paint Exterior Wooden Shingles and Clapboard Siding


Wooden shingles and clapboard siding add warmth and character to a home’s exterior, but over time, they can lose their luster due to exposure to the elements. Painting wooden siding not only revives its appearance but also provides a protective barrier against moisture, insects, and other environmental factors. In this guide, we’ll walk you through the steps to properly prepare, prime, and paint your wooden shingles and clapboard siding for a professional, long-lasting finish.


1. Why Paint Wooden Shingles and Clapboard Siding?

Wooden siding offers natural beauty and excellent insulation, but it requires periodic maintenance to keep it in good shape. Painting helps protect the wood from sun exposure, rain, and temperature fluctuations, preventing issues like warping, rotting, and peeling. With proper care and a fresh coat of paint, your wood siding can look fantastic for years to come.


2. Preparation: Essential Steps for Long-Lasting Results

Preparation is the key to achieving a flawless, long-lasting paint job on wooden shingles and clapboard siding.

Clean the Surface First, remove dirt, mold, and mildew from the surface by washing the siding with a mild detergent solution and a soft-bristle brush. For tougher stains, consider using a power washer set to a low-pressure setting. Be cautious not to damage the wood, especially if it’s older or has weakened areas. Allow the siding to dry completely for at least 24 hours before moving on.

Scrape and Sand Next, inspect the wood for any loose or flaking paint. Use a paint scraper to remove any peeling areas, then sand those spots with medium-grit sandpaper to create a smooth surface. For areas where old paint is difficult to remove, a wire brush can be helpful. Finish with a finer sandpaper to ensure a smooth base for painting.

Repair Any Damage Check for cracks, holes, or soft spots in the wood. Fill smaller cracks with a high-quality wood filler and use caulk for gaps around windows, doors, and joints. For more extensive damage, you may need to replace individual shingles or clapboards. Let the repairs dry and cure before priming.


3. Priming: Creating a Solid Base

Choose a Primer Made for Wood Siding Selecting the right primer is essential for the paint to adhere properly. Use a high-quality, oil-based or latex primer specifically designed for wood siding. Oil-based primers are generally better for cedar shingles, as they block stains and help seal the wood. Apply the primer evenly, covering the entire surface, and allow it to dry fully according to the manufacturer’s instructions.

Seal the Edges and Joints When priming, make sure to brush primer along the edges of the clapboards and shingles. This prevents moisture from seeping behind the paint and causing peeling or bubbling. Pay extra attention to areas around trim, windows, and doors.


4. Painting Process: Step-by-Step for the Best Finish

Use the Right Tools For clapboard siding, a paint roller with a thick nap is ideal for covering larger areas, while a brush will help you get into edges and corners. For shingles, a high-quality brush is best, as it allows you to work paint into the textured surfaces and overlaps.

Choose High-Quality Exterior Paint Select a 100% acrylic latex paint designed for exterior use. Acrylic paints are more flexible than oil-based paints, allowing them to withstand the expansion and contraction of wood as temperatures change. If you’re painting cedar shingles, be sure to choose a paint that resists bleed-through, as tannins in cedar can stain lighter paint colors.

Apply Two Coats of Paint For a durable, uniform finish, apply two coats of paint. Start at the top of the siding and work your way down, painting in the direction of the wood grain. This will prevent drips and allow for even coverage. Allow the first coat to dry completely before applying the second, following the paint manufacturer's recommendations for drying times.

Mind the Weather The ideal temperature for painting exterior wood siding is between 50°F and 85°F, with low humidity. Avoid painting in direct sunlight, as this can cause the paint to dry too quickly and lead to an uneven finish. Also, be mindful of rain, as it can wash away paint if it hasn’t had time to cure.

5. Maintaining Painted Wooden Siding

Proper maintenance will extend the life of your painted wood siding and keep it looking fresh:

Inspect Regularly for Signs of Wear Check your siding annually for signs of cracking, peeling, or other damage. Addressing these issues early can prevent the need for more extensive repairs down the road.

Clean the Siding Annually Wash your siding at least once a year with a gentle cleanser to remove dirt and mildew. Avoid high-pressure washing, as it can damage the paint and wood underneath.

Touch Up as Needed Keep some leftover paint for touch-ups. This will help you maintain a consistent look and prolong the lifespan of your paint job, especially in high-traffic areas that may see more wear.
