many of my completed exterior projects required exterior stucco
repair or the correction of improper stucco installation, with the
addition of new paint. So here's a few things to note if you've got a
home or business with a stucco exterior.
Stucco, an ancient building material, is popular but can be prone to cracking, especially if not properly reinforced at the base layer and with an acrylic top coat. Movement cracking and buckling may occur over time, signaling the presence of moisture. And so home and building owners will require patches and caulking to seal the stucco against the elements. Left un-repaired, the elements will only hasten the exterior's degradation.
So when exactly should stucco repairs be done? As soon as big cracks, blisters and buckling start to appear. Keep your eyes on your stucco exterior. Not every day, but on occasion. There is a small window of opportunity to make effective repairs, so it's good to be aware of the exterior stucco integrity.
After the patches and caulking have been applied and properly adhered, it will be necessary to cover the repairs with layer of paint to match the stucco's original pigmentation and add another layer of protection against moisture. A number of top coatings can be used, from elastomeric to concrete paints and lime washes.
With stucco repairs, I truly believe that this isn't simply a DIY project. It requires professional craftsmanship—painters that know stucco well. Otherwise the damage may worsen and you'll be out a significant amount of money in the long run.
