How to Repair Stucco
1. Inspect and Prepare the Area
Begin by closely inspecting the damaged stucco to determine the extent of the repair needed. Use a hammer and chisel to remove any loose or damaged stucco from the area. Be thorough but gentle to avoid creating more damage.
2. Clean the Surface
Once the loose material is removed, clean the area with a stiff brush or a pressure washer to remove dirt, debris, and any remnants of old stucco. The surface needs to be clean for the new stucco to adhere properly.
3. Apply a Binding Agent
If the area is large or the existing stucco is very smooth, applying a binding agent or a concrete bonding adhesive can help the new stucco adhere better. Brush this over the exposed substrate and let it dry according to the manufacturer’s instructions.
4. Install Stucco Mesh (if needed)
For larger repairs, we advise using a stucco mesh or fiberglass mesh over the area. This helps reinforce the repair and prevents cracking. Cut the mesh to fit over the repair site and affix it securely.
5. Mix the Stucco
Prepare your stucco mix according to the manufacturer’s instructions. For small patches, pre-mixed stucco may be a good option, but for larger areas or specific types of finish, you might need to mix your own.
6. Apply the Scratch Coat
Using a trowel, apply the first layer of stucco to the repair area. Press it through the mesh and smooth it out to ensure good contact with the surface underneath. This layer should be about 1/4 inch thick. Once
applied, use the trowel to lightly scratch the surface. Allow this layer to cure for 24 to 48 hours.
7. Apply the Brown Coat
After the scratch coat has dried and cured, apply the second layer, or brown coat, which should also be about 1/4 inch thick. Smooth it out as much as possible to the level of the surrounding stucco. Allow this layer to cure, keeping it slightly moist for a few days to prevent it from drying too quickly, which can lead to cracks.
8. Finish Coat
The final layer is the finish coat, which should match the texture of the existing stucco. Apply this layer carefully, using various tools depending on the desired texture. After applying, allow the stucco to dry completely, following any specific curing instructions provided by the stucco manufacturer.
9. Painting (if necessary)
If the rest of the wall is painted, wait for the stucco to cure fully before painting the repaired area to match the surrounding surfaces.
Stucco Crack Repair
Repairing cracks in stucco is an important maintenance task to prevent water damage and further deterioration. Small, hairline cracks can often be addressed with a high-quality, paintable caulk. It’s important to choose a caulk that is flexible and designed for exterior use to accommodate any expansion and contraction caused by temperature changes. For larger cracks, a more involved approach might be necessary. These typically require the application of a patching compound specifically made for stucco repair.

Hiring a Professional
The cost of stucco repair can vary widely depending on a few key factors like the extent of the damage and your location. Hiring a professional to handle the repair is generally the more straightforward approach, although it’s usually the costlier option. On average, professional stucco repair can range from about $500 to several thousand dollars. For smaller jobs, such as patching a few hairline cracks, costs might be on the lower end. But if you’re dealing with large areas of damage or needing a complete resurfacing, the price can quickly climb. Professionals bring expertise and efficiency to the job, making sure that the finish matches seamlessly with your existing stucco, which can be invaluable, especially if the damage is extensive.

DIY
Tackling stucco repair as a DIY project can significantly cut down your costs. You’ll only be paying for materials, which can run anywhere from $50 to $100 for basic supplies depending on the size of the area that needs repair. This approach works best for those who are handy and have a good understanding of home repair projects. Even though it takes more time and effort, DIY repair allows you to control the process and can be very rewarding when finished.
Can You Paint Stucco?
Yes, you can definitely paint stucco. It’s a great way to refresh the appearance of your home and add a layer of protection against the elements. Before painting, double-check that the stucco surface is clean and in good condition. Any cracks or damage should be fixed to prevent further issues after painting.
How to Drill Into Stucco
Drilling into stucco requires careful preparation and the right technique to avoid damaging the underlying material. Start by choosing a drill bit that is suitable for masonry work; a carbide-tipped masonry bit works well for this purpose. Before you start drilling, be sure to check the area for any underlying wiring or plumbing to avoid expensive mistakes. Once you’re ready to drill, set your drill to a lower speed to prevent the stucco from overheating and cracking. Begin by applying gentle pressure, allowing the drill bit to gradually penetrate the stucco. Drilling slowly helps to maintain control and precision, reducing the risk of the stucco cracking or chipping. After you’ve drilled the necessary holes, you can insert wall anchors that are appropriate for the weight and type of object you plan to hang. This ensures a secure hold, minimizing the risk of damage to both the stucco and the mounted items.
Tools Needed to Repair Stucco
Repairing stucco requires a set of specific tools to get the job done correctly and efficiently. Here are the basic tools you’ll need:
- Hawk and Trowel – These are fundamental for applying and smoothing the stucco mix. The hawk is a flat, handheld board that holds the stucco, while the trowel is used to apply and shape it.
- Mixing Paddle and Bucket – A sturdy mixing paddle, which can be attached to a power drill, is ideal for mixing stucco mix uniformly. Use a large bucket to mix the stucco.
- Chisel and Hammer – These tools are useful for removing loose or damaged stucco before applying the new layer.
- Wire Brush – This is used to clean the existing stucco surface, ensuring it’s free from dust and debris which helps the new stucco adhere better.
- Utility Knife – A sharp knife is handy for cutting the mesh or fabric that is often used to reinforce the repair area.
- Stucco Mesh or Fabric – This is applied over the area needing repair to reinforce the new stucco and help prevent cracks.
- Sponge and Brushes – These are used for finishing touches, particularly for achieving specific textures or smoothing out the stucco surface.
- Safety Gear – Always wear safety glasses, gloves, and a dust mask to protect against dust and debris when working with stucco. Best Stucco Paints
Knowing which paint to use when starting a project can be half the battle because there seem to be endless options out there. But, when it all shakes out, two types of paint rise to the top for stucco jobs: acrylic latex and elastomeric paints.
- Acrylic Latex Paint: This type of paint is highly favored for its durability and ease of application. Acrylic latex paints are water-based, which means they’re easier to clean up and less harsh on the environment than oil-based options. They allow the stucco to breathe, reducing the risk of trapped moisture, which can lead to cracking and peeling. Ideal for a variety of weather conditions, acrylic latex paints come in a wide range of colors, giving you plenty of flexibility.
- Elastomeric Paint: Elastomeric paint is like a shield for your stucco, offering a thicker, more flexible finish. This paint type is excellent for bridging small cracks and imperfections, essentially creating a waterproof barrier that helps protect the stucco from the elements. Because of its elasticity, it can expand and contract with the stucco during temperature changes, preventing cracks. Although it’s generally more expensive than acrylic latex, its protective qualities can be worth the cost, especially in harsh weather areas.
