How to Fix Cracks in Rough Colored Stucco

Stucco is a common building material made by mixing concrete, water and sand, often used on the exterior of buildings. Cracks in stucco can ruin the look of your home; although it is a textured material, the cracks will look obvious and out of place. Too many cracks can allow water to seep into the wood, thus creating damage to the frame of the house. A professional should repair large cracks in the stucco, but homeowners can repair smaller cracks with a few simple tools.

Spray bottle or hose with misting attachment
Wire brush
Stucco patch mixture
Stucco caulk tube
Primer
Paint
Paintbrush or paint roller

Instructions

- 1
  Chip off a small piece of the stucco, and bring it to a home improvement store to get color matched paint. Mismatched paint will bring attention to the repair job and possibly make it look worse, so test the paint on a less visible spot on the house before repair.

  Clean the crack with the wire brush, scrubbing to remove dirt and any loose pieces of stucco. Mist the crack and the surrounding stucco with the hose, ensuring that excess water doesn't get into the crack. Check the wire frame under the stucco to ensure that it's intact; this frame allows the stucco patch to stick.
- 3
  Seal the crack with the appropriate patching material, and ensure that the patch matches the rough texture of the rest of the stucco. For smaller cracks, caulk will work fine; just squeeze the tube, applying the caulk directly into the crack. Larger cracks require stucco patch, which you can pack into the crack using your fingers.

  Apply primer once the stucco patch is dry using the paintbrush or roller. Allow the primer to dry thoroughly, as per the instructions on the container, and then paint over it. You may need to apply more than one coat of paint to get a perfect color match.
