How to Patch Stucco Cracks and Holes
Hairline versus real cracks
Hairline cracks take a paintable elastomeric caulk that flexes with the wall. Wider cracks and holes need stucco patch or a scratch-and-finish coat to rebuild the surface. Using caulk on a big hole (or hard patch on a moving hairline) is why repairs fail.
Clean, dampen, fill
Rake out loose material and dust, dampen the area so the patch bonds instead of drying too fast, and fill in layers rather than one thick glob. Patience here is what makes it last in our climate.
Match texture and seal
Match your wall’s texture — sponge, dash, or knockdown — then coat with elastomeric paint. That flexible, waterproof coating is the Florida-correct finish; ordinary paint cracks again the next rainy season.
When a crack is a warning
Hairlines are normal. Stair-step cracks, widening cracks, or ones that keep reopening can signal settling or a structural issue — we patch cosmetic stucco and flag anything that needs a closer look. We repair stucco across Broward.
Frequently asked
Why does my stucco crack keep coming back?
Usually the wrong material (hard patch on a moving crack) or no elastomeric seal — or movement underneath that needs addressing first.
Caulk or stucco patch?
Elastomeric caulk for hairlines; stucco patch or a base-and-finish coat for wider cracks and holes.
Can you match the texture?
Yes — sponge, dash and knockdown textures can be matched so the patch blends in once it’s painted.
Are stair-step cracks serious?
They can indicate settling or a structural issue — worth a closer look. We handle cosmetic stucco and refer structural evaluation.
