German schmear is a durable brick masonry coating. It should last at least a decade or two without flaking or fading, even with minimal maintenance. This makes it an economical option compared to the cost of painting your house exterior, which usually needs to be repainted every five to 10 years to keep it looking its best—thus costing more over the same time period.

Yes, you can apply the stucco yourself, but it is a time- and labor-intensive project, especially on the exterior of a whole house. DIY stucco is better suited for repairing stucco siding or siding a smaller building, such as a shed or garage. Since most of the cost of stucco siding goes to labor, you can cut down significantly on the total if you’re up for the challenge.

Failing to repair damaged stucco can lead to significant problems. Cracks can grow and deepen, allowing water and moisture to get behind the stucco. This moisture intrusion can cause water damage, structural issues, and mold or mildew growth. Delaying repairs will likely cost more in the long run as the damage worsens, so it's best to repair your stucco as soon as you notice any signs of damage, such as cracks, holes, or discoloration.

To repair damaged exterior stucco, you’ll first remove all loose and crumbling material from the damaged area. You then need to thoroughly clean the area and dampen it to ensure proper bonding. After that, you’ll apply a bonding agent to the repair area, then apply new stucco in layers, allowing for curing time between each layer. The final coat should be textured to match the surrounding stucco pattern as closely as possible. Once fully cured, the repaired area can be painted to match the rest of the wall if needed.
