How Does Humidity Impact Stucco?

June 3, 2019

Stucco is a material that has been used as a type of siding for hundreds of years. It has an appearance similar to clay or cement and is typically used on a building’s exterior, though it can be used in the interior as well. The traditional form of stucco is made with a mixture of lime, sand and water, resulting in a long-lasting, durable substance. This is often a cost-effective and versatile siding option for homeowners.

Of course, quality installation is key when you’re considering stucco siding for your home. You want to find the right stucco company in Bluffton, SC to partner with. You’ll also want to consider the impact of moisture on stucco before you make an investment.

Humid climates and stucco

Stucco is known for repelling moisture in most normal climate conditions. On the other hand, in rainy environments, it can be more prone to oversaturation. This could lead to other aspects of the building retaining moisture over time.

Fortunately, expert installation can avoid many of these problems. The installation of stucco is labor intensive, but the long-term benefits of having this durable, beautiful siding are worth it for many homeowners.


Traditional hard stucco is a type of finish that has stood the test of time. Using Portland cement, when mixed with water, it creates a plaster tough enough to handle difficult conditions. Whether it’s applied by hand or machine, traditional hard stucco has both high impact resistance and water resistance, while also being a breathable material that allows water vapor to escape.

Issues like cracking are often the result of poor installation. Buildings are subject to a variety of stresses. For this reason, it’s important that the stucco be installed using the right mix of cement and sand. Also, cement needs to set and harden, which is where high-quality sand comes in during curing. Poor quality sand can lead to shrinkage stress, which in turn leads to cracks. Another culprit is excessive thickness if the installer only uses a single coat instead of multiple coats.

Avoiding costly repairs

Because of potential moisture problems, it’s critical for a stucco siding job to be done right the first time. You want to work with a contractor who has your best interests in mind and has the trust of the community.
