Stucco failure is a growing issue across Central Florida, especially in multi-story homes. Many homeowners in Orlando, Winter Park, and surrounding areas are dealing with cracks, water intrusion, and costly repairs—particularly on second stories, where exposure to the elements is highest.


At RoMac Building Supply, we recently faced this exact problem at our Training Center in Leesburg, FL. Instead of patching the issue with more stucco, we found a better, longer-lasting solutionHardie Architectural Panel with a mounted sand finish.

The Problem: Why is Stucco Failing in Florida?

Traditional stucco is meant to provide a durable, weather-resistant finish, but in Florida’s hot, humid, and storm-prone climate, it often fails prematurely. Common issues include:

  • Cracking: Stucco expands and contracts with temperature changes, leading to fractures.

  • Water Intrusion: Florida’s frequent rainstorms force moisture behind the stucco, which gets trapped and causes hidden structural damage.

  • Mold and Rot: Once water is behind the surface, mold and rot spread quickly, weakening the home’s structure.

These problems are especially severe on second-story exteriors, where wind-driven rain is a major factor.


Our Solution: Hardie Architectural Panel with a Mounted Sand Finish

Rather than replacing failing stucco with more stucco, we opted for a proven alternativeHardie Architectural Panel with a mounted sand finish. This product provides the clean, modern look of stucco but with superior durability and moisture resistance.

Here’s how we repaired and protected our building:


1. Assessing the Damage

We brought in Larry Mott of Mott Builders to inspect the building, uncovering severe water intrusion and damaged sheathing that had to be replaced.

2. Installing a Superior Moisture Barrier

To prevent future water issues, we wrapped the entire building with Protecto Wrap, a high-performance waterproofing membrane that blocks moisture from penetrating behind the surface.

3. Installing Hardie Architectural Panel with a Mounted Sand Finish

Once the building was fully sealed, we installed Hardie Architectural Panel with a mounted sand finish. This product is designed to withstand Florida’s extreme weather conditions while maintaining the smooth, stucco-like appearance that many homeowners prefer.

4. Finishing the Job with Professional Painting

Finally, Kelley Painting Services primed and painted the exterior, ensuring a long-lasting, durable finish that will protect the building for years to come.
