Stucco has been used in home construction for centuries. Made of a mixture of sand, cement and water, stucco is an extremely durable building material and is capable of standing up to extremes of weather and temperature. An exterior stucco surface has the advantage of also being eco-friendly, having very little impact on the surrounding environment. However, one drawback to stucco is that it is extremely porous, making painting rather difficult. Fortunately, the following steps will show you how to get around this and end up with a beautifully painted stucco exterior.
Warning: Keep in mind that if you have newly applied stucco on your home's exterior, it generally has to cure for at least three months before you paint it.
What You Will Need
Acrylic Latex Caulk
Step 1. Use a power washer to spray your exterior stucco so as to remove any dirt or debris. Don't use the maximum setting on the power washer, since you don't want to damage the stucco. Make sure that you get in all the cracks and crevices of the stucco, since it has to be clean for the paint you're going to apply to properly adhere.
Note: Choose a dry day in the fall to paint exterior stucco.
Step 2. Wait as long as it takes for the stucco to completely dry. Trying to paint on a wet surface will result in a terrible paint job.
Step 3. Examine the stucco closely for any cracks that might have appeared over the years. If you see any, use an acrylic latex caulk to fill all of these cracks. Allow the caulk to dry according to the manufacturer's directions.
Step 4. Choose an acrylic-based paint that fits well with the decor of your home. Do not use an oil-based paint, since this will not allow the stucco to breathe and will result in a buildup of moisture within the stucco.
Step 5. Fill a paint sprayer with the paint you have chosen and spray one coat of this paint across the stucco. Use a back-and-forth motion in which you overlap the paint. After the first coat has completely dried, you might want to add a second coat.
Note: While you could use a roller brush or paintbrush to paint your home's exterior stucco, this can take a lot of time and be very difficult, since you will have to get paint into all the little crevices.
