Stucco is one of the most popular choices for exterior sidings in the US and it’s known for its durability and distinctive texture. But when it comes time to refresh its look, many homeowners wonder, “Can you paint stucco?”
The answer is a resounding yes! However, painting stucco isn’t as straightforward as slapping on a coat of paint. If done incorrectly, it can lead to unsightly peeling, cracking, or uneven finishes.
But don’t worry—we’ve got you covered! In this guide, we’ll walk you through the essential steps to paint stucco like a pro, ensuring a beautiful and long-lasting result.
What is Stucco?
Stucco is one of those building materials that’s been around forever but still has a bit of mystery to it, especially if you’re new to the world of home improvement.
At its core, stucco is a type of plaster made from a mix of cement, sand, and water. This basic recipe can be altered depending on the specific needs of the project, sometimes incorporating lime or synthetic materials to enhance certain properties.
Traditional stucco, the kind that has been used for centuries, is typically applied in several layers over a wire mesh or lath. This creates a strong, durable finish that can withstand the elements and provides that iconic textured look we all associate with stucco homes.
It’s especially common in warm, dry climates like those in the Southwest and California, where it’s valued for its ability to handle heat and resist fire.
But not all stucco is created equal. Over the years, synthetic stucco, also known as Exterior Insulation and Finish Systems (EIFS), has become more popular.
This modern version of stucco includes a foam insulation board covered with a synthetic coating that mimics the appearance of traditional stucco.
The key difference here is that synthetic stucco is much more flexible, which can be an advantage in areas that experience frequent freeze-thaw cycles. However, this flexibility comes at a cost—synthetic stucco is more prone to water damage if not installed correctly, which can lead to issues like mold and mildew.
Now, when it comes to painting stucco, the unique properties of this material come into play in some pretty interesting ways.
The biggest challenge is the surface itself. Stucco is naturally porous and textured, which can make applying paint a bit tricky. The porosity means that stucco can absorb a lot of paint, requiring more product than you might expect—sometimes even double what you’d use on a smoother surface like wood or vinyl siding.
And the texture? Well, that’s a whole other story.
The texture of stucco is what gives it its character, but it also presents a challenge when you’re trying to get an even coat of paint.
Some try to brush stucco, and let me tell you, it’s a nightmare. The rough surface just chews up brushes, and it’s nearly impossible to get paint into all the nooks and crannies.
That’s why spraying is often the method of choice when painting stucco. Spraying allows the paint to reach those deep crevices and it applies a lot of paint, but even then, you need to backroll it, at least on the first layer.
This step helps the paint adhere better and will fill in those pesky pinholes that can mar the finish if left unattended.
Choosing the Right Paint for Stucco
Another important factor to keep in mind is the type of paint you choose. For traditional stucco, many homeowners find that high-quality acrylic latex paint is an excellent option.
It adheres well, offers solid coverage, and provides a decent level of breathability—important for preventing moisture buildup.
However, if you’re looking for something that truly excels in breathability and durability, silicate paint is the best choice for stucco.
It forms a chemical bond with the stucco, creating a finish that’s not only long-lasting but also allows the stucco to breathe even better, making it a top contender for those who want to avoid moisture issues.
However, keep in mind that silicate paint must be used on bare stucco surfaces and can be a bit pricier than other options.
On the other hand, if you’re dealing with hairline cracks, elastomeric paint might be your go-to. Its flexibility helps bridge those tiny cracks, though it can slightly smooth out the texture of the stucco, which may not be everyone’s preference.
Each type has its strengths, so your choice will depend on your specific needs, budget and the look you’re going for.
Just be ready for a bit of a workout though, it’s not the easiest material to paint, but the results are always worth it.
Preparing Stucco for Painting
You’ve got to clean the stucco thoroughly before you even think about picking up a paintbrush or sprayer. Stucco is notorious for trapping dirt, mildew, and even efflorescence—a white, powdery residue that forms when water evaporates from the stucco, leaving mineral deposits behind.
If you paint over this gunk, you’re basically setting yourself up for failure. The paint won’t adhere properly, and before you know it, you’ll have peeling, blistering, and all sorts of unsightly problems. I’ve seen this happen too many times, especially when someone is trying to cut corners.
When it comes to cleaning stucco, I recommend using a pressure washer with a rotating nozzle. This setup is key because the rotating action helps to agitate the surface, blasting away dirt and mildew more effectively than a standard nozzle.
But you have to be careful with the pressure—you don’t want to damage the stucco by getting too close or using too high of a setting. Aim for around 1500 to 2500 PSI, and keep the nozzle about two feet from the surface.
Once the stucco is clean and dry, the next step is to inspect the surface for cracks and damage.
This is where a lot of folks trip up, thinking they can just slap some paint over small cracks and call it a day.
But here’s the thing: cracks in stucco are like ticking time bombs. If you don’t address them properly, they’ll continue to expand, and no amount of paint is going to stop that.
Use a sanded stucco caulk to fill cracks. This type of caulk is flexible, which is crucial because stucco expands and contracts with temperature changes. It also contains sand to match the texture of stucco.
The key is to make sure the caulk is fully filling the crack. Don’t just skim over the surface—you’ve got to work it into the crack, then smooth it out with a wet sponge or brush to blend it with the surrounding texture.
It’s a bit of an art form, really, but once you get the hang of it, you’ll see how much better your repairs look.
If you need to patch up some stucco before painting, you can use a pre-mixed stucco patch product. These are convenient and easy to use for repairing cracks, holes, or any small areas of damage on your stucco surfaces.
Products like Quikrete Pre-Mixed Stucco Patch or Sika Ready-Mix Stucco Patch are excellent options.
They offer a durable, flexible finish that blends well with the surrounding stucco, making it easy to achieve a seamless repair. These products are available online at retailers like Home Depot or directly from the manufacturer’s site like Quikrete.
For larger patches or if you prefer a more traditional approach, you can use a stucco mix, which typically requires blending with water on-site.
This mix usually contains cement, sand, and water, and can be adjusted to match the texture of your existing stucco.
Do You Need to Prime Stucco?
Yes, priming stucco is typically recommended before painting, especially if the stucco is new or if it hasn’t been painted before. Priming helps to seal the porous surface of stucco, ensuring better paint adhesion and uniform coverage.
It also prevents the stucco from absorbing too much paint, which can lead to uneven color and texture.
For the best results on stucco surfaces, a primer specifically designed for masonry or concrete, for example, the Loxon Concrete & Masonry Primer from Sherwin-Williams, can be a good choice.
This type of primer is particularly useful if the stucco is new, as it can help manage the high pH levels that fresh stucco often has.
Additionally, using a primer will help prevent any potential efflorescence (white, powdery deposits) from appearing on the painted surface.
Moreover, the use of a primer is crucial when dealing with any repairs or patchwork on stucco. It ensures that the paint will blend seamlessly with the rest of the surface, creating a uniform finish.
If you’re using a high-quality paint like Sherwin-Williams Duration Exterior for example, this paint can act as its own primer on many surfaces, including stucco.
However, applying a dedicated primer coat can still provide additional durability and longevity, especially in areas exposed to harsh weather conditions.
Preparation is 90% of the battle when it comes to painting stucco. Sure, it takes time and effort, but the payoff is worth it—a smooth, even finish that looks great and stands up to the elements for years to come. So, take the time to do it right. Your future self will thank you!
Step-by-Step Guide to Painting Stucco
Here’s a step-by-step guide to get you through it, from gathering your materials to achieving that perfect finish.
What You Need: Tools, Equipment, and Materials
You’ll need to gather a few essential tools and materials before you start:
- Pressure Washer: A must-have for thoroughly cleaning the stucco surface before painting. Opt for a rotating nozzle to help dislodge dirt from the textured areas.
- Sanded Elastomeric Caulk: For filling any cracks or damage in the stucco. This caulk is flexible, making it ideal for surfaces that expand and contract.
- Masonry Primer: A high-quality primer designed specifically for stucco or masonry surfaces to ensure better paint adhesion.
- Paint: Choose an exterior acrylic latex paint for most stucco surfaces. Elastomeric paint is another option, especially if you’re dealing with hairline cracks, but it can smooth out the texture a bit. Choose a silicate paint if you have the budget and the stucco hasn’t been painted before.
- Rollers and Brushes: Use a roller with a 3/4-inch to 1-inch nap to handle the stucco’s rough texture. Have a few brushes on hand for cutting in around edges and details.
- Extension Pole: Attach this to your roller for easier reach, especially when working on higher sections of stucco. It helps you avoid overextending and makes the job more comfortable and efficient.
- Paint Sprayer: While not always necessary, a paint sprayer can be incredibly efficient for large stucco surfaces.
- Drop Cloths and Painter’s Tape: To protect areas around your work site, like windows, doors, and landscaping.
- Mixing Sticks and Paint Trays: Have these on hand for stirring paint and holding it while you work. You might also want a roller grid for consistent loading of the roller with paint.
- Ladder and/or Scaffolding: Depending on the height of your stucco, make sure you have safe, stable access to all areas that need painting.
How to Apply Paint on Stucco
Before you start to prime or paint your stucco we need to mask off the areas you don’t want paint on.
Use materials like drop cloths, plastic sheeting, and painter’s tape.
Now when the stucco is clean, dry and masked we can start to paint.
Start by cutting in around edges, windows, doors, and other details with a brush. This allows you to get into the tight spots that rollers or sprayers might miss.
Next, if you’re using a roller, make sure you load it up with plenty of paint. Stucco is thirsty—it’ll soak up paint quickly, so you’ll need to work fast.
Apply the paint in a W or M motion to distribute it evenly, then go over the area with long, smooth strokes to level out the finish.
If you’re dealing with heavy texture, you might find that the first coat leaves some spots under-covered. This is normal—stucco often requires two coats for full coverage.
Between coats, inspect the surface for any missed spots or areas that look thin, and touch these up before applying your second coat.
When and How to Use a Paint Sprayer for Stucco
A paint sprayer can be a lifesaver when painting large stucco surfaces, especially those with a heavy texture.
The sprayer allows you to cover more area quickly and can get paint into all those tiny nooks and crannies that rollers and brushes might miss.
When spraying stucco, apply the paint in even, overlapping passes. You’ll want to hold the sprayer about 12 to 18 inches from the surface and move it in a consistent, steady motion.
For heavy texture, you might need to spray from multiple angles to ensure full coverage. And don’t skip the back rolling step—after spraying, go over the area with a roller to press the paint into the texture and smooth out any inconsistencies.
Conclusion
Painting stucco can be a bit of a challenge, but totally doable with the right game plan. By following the steps we’ve laid out, you’ll dodge the usual headaches like peeling paint and uneven coverage.
Just remember, prepping is half the battle—don’t skip it! With the right tools and a little elbow grease, your stucco will look sharp and stand up to whatever Mother Nature throws its way. So, grab your gear, and let’s get that stucco looking brand new.
