Whatever the cause of the hole in the wall, whether due to accidental damage from a car bumper’s too close encounter with your wall, or a reminder of the plumber or electricians recent visit, repairing holes in your stucco needs your attention as soon as possible. Left unrepaired, water infiltration behind the stucco will cause wood lath to rot, and metal lath and nails to rust, which eventually will cause stucco to lose its bond and pull away from its substrate. Additional considerations are if left unrepaired, the potential for the formation of mold and mildew within the wall and the eventual migration into the living/working areas of the structure.
Once the extent of damage has been determined, a number of repair options may be considered. Small hairline cracks in stucco usually are not serious and may be sealed with a thin slurry coat consisting of the finish coat ingredients. From a professional stucco repair standpoint, DIY commercially available caulking compounds usually are not suitable long term solutions for patching holes for several reasons. Because their consistency and texture is unlike that of stucco, they tend to weather differently, and attract more dirt; as a result, DIY repairs made with caulking compounds may be highly visible, and unsightly. Holes usually will have to be cut out in preparation for more extensive repair, including replacement of the water barrier as well as lath to support the stucco patch. Most stucco repairs of this type require the skill and expertise of professionals such as the stucco repair experts at Nurse Stucco.
Honestly Evaluate Your Stucco Repair Needs
Assessing the scope of a stucco repair project is the most important step in the whole stucco repair process. The first step in repairing damaged stucco is to inspect the property for damage. Is it only one small patch that needs to be fixed? Do you need to redo a large surface area? Guessing wrong in this area, and hiring a home handyman to do a simple patch that soon needs to be a much bigger project can be an expensive mistake.
