You’ll want to start by following the best way to prepare a house exterior for painting.
Cleaning stucco walls before painting them is important. Dirt, oils, and other things can get between the paint and the wall. The paint won’t stick very well and will start cracking and peeling quickly. Your home won’t be as protected from moisture and heat damage if this happens.
You may only need a stiff brush or push broom to clean your stucco walls. If it’s really dirty, your exterior walls may need pressure washing while your interior walls may need a vacuum. Cleansers can be used on mold, mildew, etc.
Masonry caulk is great for repairing hairline cracks in stucco walls. A putty knife and a dry stucco repair product are better for larger cracks. The packaging should have all the instructions you need.
The best type of exterior paint and primer for stucco homes are acrylic ones. They stick better to stucco than other types of paint, which means it should look better for longer. High-quality paints may cost more upfront but they should look better for longer, making it worth the investment.
Plan on having to use more paint than you think. Stucco’s textured surface gives it more surface area which means you’ll need more paint than if it were a flat wall.
Start painting your stucco walls by using a brush to get the edges. Then use a thick nap roller for the rest. The more texture your stucco walls have the thicker your roller nap will need to be. This helps it get into all the nooks and crannies.
When painting, have a roller grid inside your paint bucket to help get the right amount of paint onto the roller. Dip the roller, roll it lightly against the grid, and you’re good to go! Don’t press in very hard when painting or you may see roller lines appear.
