Stucco is a beautiful finish to a home that adds texture and dimension. However, because stucco exists on the exterior of a building it is highly susceptible to damage due to the effects of inclement weather. Excessive heat, wind, rain, and freezing temperatures can crack and deteriorate the finish. But the damage can often be repaired with a few basic tips on how to repair stucco.
Fixing Cracked Stucco
Small horizontal cracks are a quick fix. Invest in some high-quality caulk that is specifically made for painting over to ensure a pleasing finish. Simply use your fingers to press the caulking into small cracks, then smooth it over with a damp cloth. Wipe away any excess caulk and follow the instructions for drying. Once the area has completely dried, you may give it a matching coat of paint to finish off the repair.
If, however, the cracks in your stucco are vertical, it may be a sign of a much more serious problem. Knowing how to repair stucco does not extend to this issue. Vertical cracks could point to problems in the foundation of your home – particularly if they go from the roof to a door or from the base to a window. It is important to keep an eye out for this kind of stucco damage. You should immediately contact a foundation specialist to prevent the damage from becoming worse and get started on a solution.
Fixing Deteriorated Stucco
Other kinds of damage may be fixed with a patch. When you use this method of how to repair stucco, it is advisable that the area of repair be left in an irregular shape. This, in addition to the design of the stucco itself, will help conceal the repair job for a clean finish. Patching is a preferable method of repair because it is considerably less expensive than wholesale replacement. This method will also blend in better if the stucco is painted.
The best way how to repair stucco with a patch is by first removing debris from the wall with a brush. The area will then need to be squared off with a very sharp hatchet or diamond blade saw. Extreme caution should be used. If the area is prepared thoroughly, the patch should not require a bonding agent, although sometimes this is helpful. Again, finishing off the job with matching paint will help to conceal the patch and the repair.
