Stucco should not be painted!
Painting stucco seals the system and prohibits it from gassing small amounts of moisture and can cause bubbling under the finish coat from moisture trying to escape. Painting also causes a maintenance issue. If you paint it once you must paint it again down the road. Also, paint fills in the texture of the stucco. After a few paintings, the stucco will appear like plastic and the character of the stucco will disappear. Let the stucco age, it will fade evenly through the years giving it character. Stucco should be refinished every fifteen to twenty years; finishes eventually wear and loose their protective element. The recoat can be a perfect time to change the color of your home.
Sealant application around windows, doors and all penetrations must be maintained! Water movement through these areas causes roughly eighty-five percent of stucco failures. This problem can be easily remedied by using a qualified factory trained applicator to seal around all stucco penetrations.
I hope this brief overview helps you understand the maintenance issues of a stucco home.
