Preparing for Paint 1. Remove dust and dirt from the surface of the stucco. In many cases, this requires only a thorough brushing of the stucco with the stiff bristles of a push broom. If the stucco has a deep texture, however, you might have to use a power washer to get the dirt out of the deepest crevices. 2. Caulk hairline cracks in the stucco with masonry-compatible caulking. For larger cracks, use a putty knife to remove loose debris first and then fill the cracks with a dry stucco repair product, mixed with water, as directed on the package. No Matches Found. Please try your search again. 3. Wait seven to 10 days to allow a stucco repair product to cure before painting. The suggested wait time can be found on the stucco repair productís instruction label. 4. Apply painterís tape around door and window trim.
Painting Stucco 1. Apply a coat of exterior masonry primer to the stucco. Start by brushing the primer around the edges first and then roll on the primer with a thick-nap roller on the flat wall expanses. 2. Use a roller grid for the best results. A roller grid is an inexpensive plastic grid that fits into a 5-gallon bucket. After pouring the primer into the bucket, dip the roller into the primer and lightly roll upward along the grid to remove excess paint. 3. Cover the entire stucco surface with one coat of primer. If the old stucco is stained, use a stain-blocking primer to keep the stains from bleeding through. The larger the stucco texture, the thicker the nap of the roller must be to effectively distribute paint into the crevices. Let the nap do the work, donít push the roller against the wall or you could end up with roller streaks. 4. Let the primer dry for the time suggested on the primer container before painting. 5. Brush on a light coat of exterior masonry paint around the doors and windows with a paintbrush. 6. Roll the rest of the stucco with a large-nap roller, using the roller grid and the 5-gallon bucket to hold the paint. 7. Let the first coat of paint dry and add one or more additional coats, using the same rolling method. Two or more light coats are better than one heavy coat of paint. 8. Cut the painterís tape from around doors and windows before pulling it off, which can pull off some of the paint from the stucco. Hold a straightedge along the edge of the tape and score the edge of the tape lightly with a sharp utility knife. You can then pull the painterís tape off.
