The Limitations of Stucco as an Exterior Finish: How Rhino Shield Overcomes Them

Stucco, a time-tested building material, has been used for thousands of years to texture and protect the exterior surfaces of homes and buildings. Its durability and versatility have made it a popular choice, especially in regions with warmer climates and limited access to lumber.


However, here at Rhino Shield, we’re often asked, “What are the downsides of using stucco?” and “How do I mitigate the drawbacks of using stucco?” Today, we’ll answer those questions to give you a better idea of how our product and procedures complement stucco.


What Is Stucco?

Historically, stucco’s components were cement, sand, lime, and water. Although, most modern stucco includes the added benefit of polymers for enhanced flexibility. This combination forms a plaster that people today typically use for siding a home’s exterior.


Based on the findings of the Census Bureau’s Survey of Construction (SOC), at 28 percent of homes built for single families, stucco siding was the most popular option in 2021.


Stucco's Strengths

Stucco's longevity in the home development and improvement market can be attributed to a few factors.

  • Its resilience in hot and dry climates
  • Its cost-effectiveness
  • Its availability


These benefits have made stucco a go-to option for residential and commercial construction, particularly in hot and arid regions like California, Nevada, Arizona, and New Mexico. It is more prevalent in these environments because the raw materials are more readily available, which reduces cost. And since stucco is prone to water-related issues, dry areas are an optimal choice for its use.


In recent years, wood has become an expensive building material, leading consumers to look for other options. Stucco has always been a popular alternative because, unlike wood:

  • It doesn’t rot.
  • It isn’t susceptible to termites.
  • It’s not as prone to water damage.


Stucco’s Limitations

One of the significant issues with traditional stucco is its tendency to fade over time. Exposure to sunlight can cause the color of stucco to diminish, which can mar the aesthetic appeal of your home. Moreover, stucco is prone to cracking. While minor cracks are common, a bad application or unchecked cracking can lead to costly repairs. This may lead to a complete redo of the stucco finish.


Stucco's tendency to absorb and retain heat can be problematic, especially in warmer seasons. Additionally, stucco is a poor insulator, which means it won’t easily trap cold air from inside your home. This can result in increased energy costs to keep your house cool.


Stucco's porous nature also makes it susceptible to water retention, which can encourage the growth of unsightly and damaging biological growth.

  • Trench the foundation as needed.
  • Apply our unique primer that seals, penetrates, and bonds to the stucco substrate.
