Short answer. 100 percent acrylic exterior paint is the right choice for most California stucco. Elastomeric coating is better when hairline cracks are present or waterproofing is the priority. Specify a quality brand with at least a 15-year warranty, use an alkali-resistant primer, and apply two full coats.
The four paint types for stucco
1. 100 percent acrylic exterior paint
The default choice. Breathable, durable, fade-resistant. Easy to repaint years later. Examples: Sherwin-Williams Duration, Benjamin Moore Aura Exterior, Behr Marquee. Cost: $50 to $80 per gallon.
2. Elastomeric coating
Thick rubber-like coating. Bridges hairline cracks, waterproofs the surface, hides texture imperfections. Heavier application. Examples: Sherwin-Williams Conflex, Dunn-Edwards EVERSHIELD, Rhino Shield. Cost: $60 to $100 per gallon.
3. Masonry paint
Alkali-resistant formulation for new uncured stucco. Only needed when painting before 28 days of cure. Examples: Sherwin-Williams Loxon, Benjamin Moore Ultra Spec Masonry. Cost: $45 to $70 per gallon.
4. Limewash or mineral paint
Old-world finish that penetrates stucco rather than coating it. Beautiful matte appearance. Less common in California due to color limits and higher reapplication frequency.
