How To Fix Your Cracking Stucco
Cracks in stucco can be more than just a cosmetic issue—they can lead to water damage and further structural problems if left unaddressed. Taking the right approach to fix these cracks can save time, money, and prevent future issues. Here's how to repair cracking stucco effectively.
Assessing the Damage
Before starting any repairs, it’s important to assess the extent of the damage. Small hairline cracks are usually superficial, but larger cracks may indicate more serious issues, like settling or water infiltration. A simple test to check the crack's depth is to gently tap on the stucco around the crack—if it sounds hollow, the damage might be deeper. Identifying the severity of the crack will help determine the right repair method.
Cleaning the Area
Begin the repair process by cleaning the cracked area. Remove any dirt, dust, or loose stucco from the crack using a wire brush or a small scraper. It’s essential to clean the surface thoroughly to ensure that the repair material adheres properly. Afterward, rinse the area with water and let it dry completely before moving forward.
Patching the Crack
For minor cracks, use a pre-mixed stucco patching compound. Apply the compound directly into the crack using a putty knife or trowel. Press the material in firmly to fill the crack completely, ensuring no air pockets are left behind. Once filled, smooth out the surface to match the surrounding stucco. For larger cracks, you may need to apply a bonding agent or mesh before applying the patching compound for better reinforcement.
Blending the Repair
Once the patching material has dried, you’ll need to blend it seamlessly into the surrounding stucco. Use a float or a sponge to lightly texture the repair, mimicking the appearance of the rest of the wall. This step ensures that the patched area looks uniform and doesn’t stand out. If the repair isn’t perfectly blended, the texture will be noticeable, which can detract from the appearance.
Sealing the Repair
After the patching is complete and the surface is smooth, it’s important to seal the area to prevent moisture penetration. Apply a high-quality sealant or a waterproof coating over the repaired area. This will protect the stucco from water damage and ensure the repair holds up for years.
Preventing Future Cracks
To reduce the likelihood of future cracking, keep an eye on your stucco and make any small repairs early. Ensure that gutters and downspouts direct water away from the exterior walls, as water buildup can lead to cracks over time. Regularly inspect the stucco for new cracks and address them promptly to maintain the integrity of your home’s exterior.
