Question 1

How long does stucco take to cure?

Accepted Answer

•

The curing time for stucco typically takes several weeks to fully complete. During the curing process, the stucco undergoes a chemical reaction and gradually hardens. It's important to note that curing is different from drying. While the surface of the stucco may dry relatively quickly within a few hours or days, the curing process continues beneath the surface, strengthening and solidifying the stucco.

It's best to avoid excessive moisture exposure during the curing period, as it can impede the curing process. The exact curing time can vary based on factors such as temperature, humidity, and the specific stucco mixture used.

Question 3

What is the most popular stucco color?

Accepted Answer

•

Neutral colors like white, tan, beige, and light brown are the most popular stucco colors. Natural stucco has a grayish color due to the high concentration of Portland cement in the material, but most homeowners have their contractors add pigments to create a more inviting appearance. Stucco is most popular in hotter climates, where it provides ample insulation to regulate interior temperatures and keep the solar heat out. Since lighter colors reflect more sunlight, lighter stucco is more prevalent.

Question 4

Who does stucco for homes?

Accepted Answer

•

Many general contractors can handle adding stucco siding, but it’s best to hire a local stucco contractor as you’re more likely to get a clean finish on your stucco siding that maximizes curb appeal. Stucco can be a challenging material to work with, so hiring a professional contractor who has years of experience and specializes in stucco application is advisable. Compare price quotes from at least three stucco contractors in your area to find the right pro for your task.

Question 5

Should I repair or replace my stucco?

Accepted Answer

•

The decision to repair or replace stucco depends on the extent of the damage. For minor issues like small cracks, holes, dirt, stains, or discoloration, a repair is typically sufficient and more cost-effective. These issues can often be resolved with a simple repair, a deep clean, and possibly a new coat of paint. However, for more significant problems such as large cracks, peeling, mold, algae, or structural water damage, a replacement might be necessary. In these cases, it is best to call a professional stucco contractor for an inspection. An expert can assess the severity of the damage, determine if there are deeper issues, and advise whether a repair is adequate or if replacing a section or an entire wall is the more cost-effective, long-term solution.
