If you’ve lived in a house with stucco for a long time, you’ll eventually see cracks. Though it is a fairly durable material, one of the most commonly used building materials, it will begin to exhibit wear with time. This is a normal aspect of the stucco’s life cycle and is reasonably simple to repair. Cracking can happen for a variety of causes, but it’s most frequent around doors, windows, and other sharp edges.

A defective mixture or improper installation is likely to be to blame if the cracks emerge rapidly or are particularly severe. Stucco that is weak or mismanaged will last significantly less time, even if the underlying causes of the fractures are usually the same.

Stucco, on the other hand, is both robust and very simple to repair. Whether you want to hire qualified pros or do the repairs yourself, the methods are the same.

Clean the area thoroughly: all dirt, debris, dust, and other detritus must be removed. This usually necessitates a light power-washing. We like to utilize a water-based paint prep solution that we have carefully developed. You should also scrape away any residual loose particles using a scraper.

Damage Remediation: All cracks must be filled. The stucco design will need to be duplicated as the area is filled in for major areas of damage. The bulk of cracks is sealed with an elastomeric caulking filler.

With a rubber float, bigger portions of stucco patching material can be filled in. You’ll need to clean up any leftover filler and blend the design in with the rest of the wall. Remove any leftover dust or dirt after it has dried.

Painting: To match the original color of the wall, paint the repaired area. If the wall’s color has faded over time, this could be a problem. This may necessitate a complete repaint in some circumstances. To prevent needless work, most professionals are capable of combining colors on-site. We like to apply a flexible, elastomeric coating first, followed by new color-matched caulking.

The Elastomeric coating is ten times thicker than conventional latex paint and is suitable for repairing and maintaining stucco walls. The thick, flexible paint will protect the stucco from the elements and any cracking that may occur.

Final inspections and job wrap-up are just as vital as any other step. Ensure that the wall has been properly mended and cleaned while you still have all of the necessary tools.
