Exterior Stucco Crack Repair Exterior Stucco Crack Repair
Exterior stucco is beautiful when it is cared for, but a crack, or chip, in the side of it can cause problems. All such areas stand out like a sore thumb and need to be addressed; not only because of the appearance, but to maintain the structural integrity as well. This job can be slightly time consuming and messy, but it is an easy task that most homeowners can accomplish without having to hire a professional.
Step 1: Prepare the Crack or Hole
Remove all of the loose debris, dirt, and any mold or fungus that might be growing in it. Use the painter’s tool to scrape around the edges, and on the face of the wall, so that all the loose pieces are removed. If you have a small whisk broom available, use it to help with the cleaning process. This allows the bonding agent to have a solid surface to adhere to.
Step 2: Mix the Stucco Repair Material
In a five gallon bucket, mix the repair material according to the directions on the back of the package. Try to estimate how much you will need and only mix that amount, plus a little more, so that you do not waste any product. Keep in mind that some of these materials dry very quickly, so you need to work fast. Have everything ready to go so that you do not have to stop in order to find a tool, which will allow the mixture to harden.
Step 3: Spread the Stucco Repair Material
Use a clean rubber float and apply one quarter of an inch of the stucco repair mixture into the crack or hole. Press the fluid into the area as far as possible, and then allow it to dry. Continue adding one quarter inch layers until the repair material is flush with the existing stucco wall. Maintain even pressure throughout the process, and try to maintain a level working surface. This will make it easier to apply the next layer by preventing any holes or valleys within the new material.
Step 4: Final Coat
Before the final coat dries, use a clean rubber float and blend the new stucco with the texture of the old, allowing it to blend to the existing design. If there are any small cracks around the repaired area, fix them by pressing paintable caulking into it. If the existing stucco was painted, you now need to match the color and paint the area that you patched. If the stucco has not had fresh paint in a couple of years, you may want to consider painting the entire area so that the paint all blends together.
When repairing cracks, or holes, in stucco, keep all of your tools clean and in good working order. Never let the repair material dry to your tools, because it will be hard to get off, and will more than likely damage the surface of the tool.
