The most common repairs are large cracks, damaged corners and small areas of missing stucco.
- Cracks– Non-structural cracks will always occur on masonry surfaces. They can either have a random distribution or occur in large numbers. These cracks can range from hairline to 1/4 inch wide. Caulk can be effective on small tight cracks, but will fail when applied to large cracks with a lot of movement. A better alternative is to use a brush grade elastomeric sealant. This thick sealant is available with or without texture to help it blend into the surrounding surface. Apply two coats; allow each coat to dry completely.
- Damaged Areas– Any loose stucco must be removed and repaired. A professional contractor who can match the existing texture should repair large areas. Smaller areas can be repaired with specialized patching compounds. The basic steps are very easy. First chip away all loose material. Now rinse the area with water using a wire brush to remove any remaining powder or grit. The patching compound can be applied after the area has dried. The best patching compounds are a powder mixed with water. The first application will smooth the area and level it with the existing finish. The second application is to provide the necessary texture matching the surrounding stucco. Matching any texture is extremely difficult. Most likely the patched area will a little different.
