Stucco vs. Wood Siding: Best Paint Types for Scottsdale’s Climate

If you’re planning to refresh your Scottsdale home’s exterior, the surface you’re going to paint matters just as much as the color you pick. Stucco and wood siding behave completely different from one another in our desert climate, so using the wrong paint type can lead to peeling, cracking, or fading years before it should. Here’s what homeowners need to know about their exterior materials:

Painting Stucco in Scottsdale

Stucco is the dominant exterior material across the Valley as it holds up well to heat. Unfortunately, it’s porous, textured, and prone to fine cracking as it expands and contracts with temperature swings. This means a new coat of paint has to work with this movement.

Best paint types for stucco:

• 100% acrylic elastomeric paint: This is the gold standard for Scottsdale stucco. Elastomeric coatings stretch and flex with hairline cracks instead of splitting. They also form a thicker, breathable film that block moisture from monsoon rains while still letting trapped moisture escape.
• High-quality acrylic latex: This product is a solid, more budget-friendly option for stucco that’s in good condition and doesn’t have significant cracking. It’s important to pick one that is rated specifically for masonry or stucco.

What to avoid: Oil-based paints are not made for stucco. They don’t flex, trap moisture underneath, and in our heat, that combination can lead to blistering and peeling much faster.

Painting Wood Siding, Trim, and Accents

Wood is much less common than stucco in Scottsdale. However, it shows up frequently on trim, doors, beams, ramadas, and accent siding. Wood isn’t affected by moisture as much as in more humid climates, but the UV radiation and rapid heat cycling of Scottsdale can dry out and break down paint film fast.

Best paint types for wood:

• 100% acrylic latex paint with UV-resistant additives: Acrylic remains flexible as wood expands and contracts with daily temperature swings, reducing cracking and peeling.
• Oil-based or alkyd primer, followed by acrylic topcoat: For bare or weathered wood, an oil-based primer seals the surface while an acrylic topcoat handles the UV exposure better than an all-oil system would.

What to avoid: Priming wood is an essential first step, especially when it comes to south- and west-facing surfaces. Unprimed wood paint jobs tend to fail much quicker in Scottsdale’s climate.

The Bottom Line

Stucco and wood aren’t interchangeable when it comes to selecting paint. In a climate as demanding as Scottsdale’s, getting the product right is just as important as the preparation and application.
