Types of Stucco Cracks
In stucco walls, fractures may take many different forms. How you fix stucco cracks will depend on the many causes of these fractures.
Here are the signs that can help you determine the kind of stucco cracks you have.
Hairline Cracks: The typical width of these fissures is 1/16 of an inch or less. You’ll most often see these kinds of cracks. There are several causes for its emergence. Most often occur in newly constructed houses because plaster settles and shifts during construction. Hairline fractures may sometimes be caused by shifting foundations, aging wood, and building activities.

Spider Cracking: Your stucco’s cracks have a spiderweb-like appearance, hence the name. This is a sign that the base coat needs more time to cure. This might result from too much water in the mixture, a hasty drying process, or an improper application day temperature.

The lath installation process had issues, which resulted to this cracking. It probably needs to be correctly fastened, which will cause cracks to grow over time.
Diagonal Cracking: As their name suggests, these fractures are diagonal in appearance and often appear around doors and windows. They move as a result of them because of seismic shifts in the foundation. You should start by fixing any cracks on your stucco that are wider than others.
