Stucco Painting & Repair in St. Louis

Stucco is a great exterior finish, but it needs attention. Cracks form. Moisture gets in. The color fades under sun and rain. If you ignore it long enough, small problems turn into big ones.

We handle stucco painting and repair together because you cannot just paint over a cracked stucco wall and expect it to hold up. The paint will peel. The crack will come back wider. The moisture underneath will keep doing damage. We fix it first, then paint it.

Inspection and crack repair

Our process starts with a full inspection of the stucco surface. We look for hairline cracks, spider cracks, stucco separation, and soft spots that indicate moisture damage underneath. We check around windows, doors, and rooflines where water tends to collect.

For cracks, we clean them out and fill them with a flexible patching compound that moves with the wall. Stucco expands and contracts with temperature changes, so a rigid filler will just crack again. We match the existing texture. Whether that is smooth, sand finish, dash, or lace. So the repair blends in and disappears under the new paint.

Patching larger damage

Larger damage gets cut out and repatched with fresh stucco applied in layers. We build it back to match the surrounding wall thickness and texture. This kind of repair takes a day or two to cure before painting.

Cleaning the surface

Before we paint, we clean the entire surface. Stucco collects dirt, mildew, and mineral deposits that prevent paint from bonding. We use low-pressure washing to clean without blasting the texture off the wall. The surface needs to be completely dry before we apply any coating.

Why elastomeric coatings

For the paint itself, we use elastomeric coatings on most stucco jobs. Elastomeric paint is thicker than standard exterior paint. It stretches and contracts with the stucco, which prevents cracking in the paint film. It also creates a waterproof barrier that keeps moisture out while letting the wall breathe. That breathability matters. Trapped moisture inside stucco causes blistering and spalling.

We apply a masonry primer first, then two coats of elastomeric finish. We spray it on for even coverage and back-roll to work the paint into the stucco texture. This method gives you full coverage without thick buildup in the crevices.

Color and UV resistance

Color matching is straightforward. We can match any existing color or help you pick something new. Stucco takes color well, and elastomeric coatings come in a full range of tones. We also offer standard acrylic masonry paints for surfaces that are in good condition and do not need the extra flexibility of elastomeric.

UV resistance matters for stucco, especially on south- and west-facing walls that take direct sun all day. The coatings we use are formulated to resist fading, so the color holds for years instead of bleaching out in two summers.

Project timeline

A typical stucco painting job on an average home takes three to five days including prep and repair. We protect landscaping, walkways, and windows during the work. When we are done, you have a sealed, repainted surface that looks sharp and keeps water where it belongs. On the outside.
