How To Tips on Stucco Repair
Loading ...
Stucco siding is made from cement or lime-based plaster that is spread over the exterior wall to form a smooth or patterned finish. While we covered some stucco repair techniques in an earlier blog post, here are some additional tips and tricks to help you repair cracks, small holes, and other minor damages to your stucco.
For best results, do your stucco repairs on a temperate day, out of direct sunlight. Check the weather forecast to make sure the stucco repair will have time to dry before the next rainfall.
Small cracks about 1/8″ long can usually be repaired with masonry caulk. First, clean any debris from the crack. Then, carefully apply a bead of caulk to the crack. In most cases, you will want to apply a second layer of caulk a few days later. Finish up by adding sand to the final wet bead to help blend the repair.
To repair larger cracks or small holes, mix up patch material that matches the original stucco. Remove the damaged portion of the stucco, and enlarge the hole slightly to create uneven edges. You’ll want to use multiple light coats of material instead of one heavy coat. Generally, two or three coats should suffice. Make sure to allow each coat time to dry before adding the next coat. The undercoats should be smooth, and the final coat should match the texture of the wall. Practice on scrap first until you are sure you can replicate the pattern and texture.
The larger the damaged area of the stucco, the harder it is to disguise the repair to the remaining wall. For that reason you may want to hire an experienced stucco contractor for large repairs.
