How to Repair StuccoStucco can endure for 100 years or more, but that doesn’t mean it is impervious. Cracks and holes that develop in the surface let in water that can quickly lead to further damage to the stucco and the underlying surfaces. Patches of stucco can also break free from the wood or metal lath is it adhered to, resulting in loose areas that can grow over time. In this way, small holes often turn into bigger ones, along with more moisture exposure and damage. Remove the Loose StuccoRemove all loose or otherwise damaged stucco in the repair area by tapping it with a hammer and a cold chisel. Break away the loose pieces until you reach solidly adhered stucco along the entire perimeter of the area. Be careful not to damage the underlying wood lath or sheathing. Add Building PaperCut two pieces of grade D building paper to fit the patch area. Each piece should cover all exposed wood materials to create an effective moisture barrier. Install Metal LathCut a piece of galvanized metal mesh stucco lath, using metal snips. As with the building paper, the lath should match the repair area so there are no gaps between the lath and the edges of the original (well-adhered) stucco. Mix the First Batch of StuccoMix a batch of quick-setting repair stucco, following the manufacturer’s directions, using a drill and mixing paddle or, for large quantities, a mortar mixer. Apply the Scratch CoatSpray the edges of stucco around the patch area with water (to prevent premature drying of the new stucco). Scoop a fist-size amount of wet stucco onto a trowel, then sling the stucco onto the metal lath to embed the wet mix into the openings in the mesh. The stucco should be able to hold onto the mesh by itself. Apply the Brown CoatMix a batch of stucco for the second, or brown, coat. Trowel the stucco onto the patch surface in a smooth, even layer that is recessed 1/8 inch from the surrounding original stucco. Let the brown coat cure as directed, misting with water, as applicable. Apply the Final CoatMix a batch of stucco for the final, or color, coat. This coat can be a standard or custom-order color to achieve the desired look. However, it is very difficult to color-match a patch so that is blends with the surrounding stucco; hiding a patch completely often requires painting or coating the entire wall with a compatible paint or pigmented coating.

I never knew that damage could be obtained by having cracks in certain parts of the concrete. A couple of days ago, my mother told me that she wants to have a stucco service to gather information about the things that need essential repairs to prevent unnecessary rehabilitation that may cost expensive. She asked if I had any idea what would be the best option to consider. Thanks to this instructive article, I'll tell her I will consult a trusted stucco repair service as they can provide more information about the process.

Thanks for helping me understand that a full restoration process is needed when the stucco has become loose or has fallen. I will tell my sister to hire a residential stucco repair service after noticing that issue on her home's walls earlier this week. I visited her and stayed there for two days when I saw the issue which concerned me until today.
