Why Stucco Needs Elastomeric Paint in Southern Utah
St. George summers push temperatures above 110°F. That kind of heat causes stucco to expand and contract daily, widening hairline cracks over time and creating entry points for moisture. Standard latex paints crack along with the stucco. Elastomeric coatings — formulated with 100% acrylic and extra film thickness — stretch rather than crack, sealing the surface against the climate.
A properly applied elastomeric topcoat on Southern Utah stucco typically lasts 10 to 15 years and reflects UV radiation, which helps keep exterior wall temperatures lower and can reduce cooling loads during peak summer months.
Our Stucco Painting Process
Every stucco painting project follows the same five-step process. Skipping any step is where shortcuts lead to failure — especially in Washington County's climate.
- Inspect: We walk the full exterior to catalog cracks, spalling, efflorescence, and areas where previous coatings have failed. Nothing gets painted without documentation.
- Power wash: Pressure washing removes dirt, mildew, chalking, and loose paint. The surface dries for 24 to 48 hours before we touch it again — Southern Utah's low humidity usually makes this fast.
- Repair cracks and holes: Hairline cracks get elastomeric caulk; larger voids get stucco patching compound. We texture-match every repair so the finished surface looks seamless.
- Apply primer: Masonry primer goes on the full surface — especially critical on patched areas — to improve adhesion and even out absorption so the topcoat lays flat.
- Apply elastomeric topcoat: Two full coats of 100% acrylic elastomeric paint, rolled or sprayed depending on texture. The result is a uniform, flexible finish built to handle Southern Utah heat for the next decade or more.
Stucco Crack Repair Before Painting
Painting over unrepaired cracks is one of the most common mistakes in stucco work. Even if the crack is small, paint alone will not bridge a structural gap. Within one or two seasons, the crack reappears through the new finish and moisture has already been infiltrating behind the surface.
We assess every crack before painting: hairline cracks (under 1/16") are filled with flexible elastomeric caulk, wider cracks with a stucco patching compound matched to the existing texture. For cracks that suggest movement in the underlying structure, we flag those separately. The goal is a substrate that is solid before the first drop of paint goes on.
Color Matching for Existing Stucco
Many stucco repaints in St. George involve a single elevation — a sun-faded south or west face — while the rest of the house still looks good. In those cases, color matching matters. We use spectrophotometer readings from the existing surface and work with the paint supplier to produce a formula that aligns with the weathered tone of the other walls. Exact matching is not always achievable after years of UV exposure, but our approach gets as close as possible and minimizes visible seams between painted and unpainted sections.

Stucco Painting FAQ
Common questions about stucco painting in St. George, UT.
How long does stucco paint last?
A quality elastomeric coating on properly prepared stucco typically lasts 10 to 15 years in Southern Utah. West- and south-facing walls face more UV stress and may need attention sooner.
What type of paint works best on stucco?
100% acrylic elastomeric paint is the best choice for stucco in hot climates. It stretches with temperature fluctuations, bridges small cracks, and prevents moisture intrusion better than standard latex paints.
Can you paint over old stucco paint?
Yes — if the existing paint is still adhering well. Chalking, peeling, or bubbling paint must be removed and the surface re-primed. Painting over failing paint causes the new coat to fail prematurely.
How much does stucco painting cost?
Stucco painting in St. George typically runs $1.50 to $3.50 per square foot depending on condition, height, and number of coats. Contact us for a free on-site estimate.
