How To Fix Exterior Stucco Damage?

This article provides a step-by-step guide on how to repair stucco exterior walls, including small cracks and more extensive repairs. To repair damaged areas, first diagnose the problem and determine the extent of the damage by pressing your palms firmly on both sides of the hole or crack. Springy areas should be patched easily.

To repair an exterior stucco hole, safely remove loose or damaged stucco around the hole using a hammer and chisel, and clean the area thoroughly with a bonding agent. Addressing water intrusion involves fixing faulty flashings, sealing cracks, and applying a waterproof barrier to prevent moisture from penetrating the stucco.

To patch cracked or damaged stucco, clean the area of loose stucco, dirt, and debris, and use a wire brush or chisel to open up cracks slightly, creating a V-shaped groove for better adhesion. Apply a bonding agent onto the cleaned and prepped surface.

After removing dead plants, fill in any holes or gaps around broken stucco using liquid cement and sand mixture (portland cement). Remove loose or peeling paint, dust, and debris with a lightly water-dampened rag. Clean the mesh with a wire brush to ensure there are no small pieces left.

To repair larger areas of damaged stucco, ensure the damage is not due to faulty installation or moisture. Inspect/replace metal mesh underneath the removed stucco for any damage or rust.
