At first glance, epoxy floors seem nearly indestructible. They’re sleek, easy to clean, and built to take on the daily wear of garages, showrooms, and workshops. But even the best-installed floors can start showing signs of stress over time. Cracks may appear suddenly or develop slowly, and while they may seem minor at first, they can signal deeper issues that require attention.
In Orlando’s unique climate (where high humidity and year-round sun are a given), staying ahead of epoxy floor damage is critical. Here’s what you need to know if your epoxy floors are showing signs of cracking and what steps to take before a small issue turns into an expensive one.
What Cracking Means for Orlando Epoxy Floors
Cracks in epoxy flooring aren’t just about appearance. They’re often indicators that the floor system is under stress or that there were missteps during installation. Whether it’s structural movement, thermal expansion, or moisture intrusion, each crack tells a story.
If your epoxy floors are cracking, it may mean:
- The concrete slab underneath is shifting or settling
- There was insufficient surface preparation before installation
- Moisture vapor from beneath the slab is disrupting the bond
- The epoxy system used lacked flexibility for Florida’s climate
Left untreated, cracks can expand, allowing water to seep below the surface. This can result in peeling, staining, mold growth, or even structural damage over time.
Types of Cracks You Might See in Epoxy Floors
Not all cracks are the same, and recognizing the type can help determine the best course of action:
- Hairline Cracks: These are very thin and often develop due to minor shifts in the concrete or temperature changes. While not immediately dangerous, they can spread if not addressed.
- Spider Cracks: A web-like network of small cracks that can appear after installation. These may be caused by poor mixing or improper curing.
- Control Joint Cracks: If the floor wasn’t installed with proper expansion joints, cracks can form where the slab naturally wants to move.
- Deep Structural Cracks: These are wide, deep, and often run the length of the floor. They may indicate a serious issue with the concrete substrate and typically require professional remediation.
Understanding what you’re seeing is key to knowing whether a simple repair will suffice or a full resurfacing is needed.
What Causes Epoxy Cracking in Orlando Homes and Businesses?
In Central Florida, there are some environmental and application-specific reasons that epoxy floors may be more susceptible to cracking.
- Temperature Swings: Orlando may not freeze often, but the heat still causes expansion and contraction in concrete, especially in garages or exterior applications.
- Improper Substrate Prep: If the concrete wasn’t ground or profiled properly before epoxy was applied, adhesion is compromised.
- Moisture Vapor Transmission: Many older Florida homes and commercial buildings don’t have vapor barriers. That means moisture rises through the slab, pressurizing and lifting the epoxy.
- Heavy Impacts: Dropping heavy tools or moving equipment without protection can create localized stress points that eventually crack.
Knowing these risks allows you to better care for your flooring and choose the right contractor for repair or replacement.
Can Cracked Epoxy Be Repaired or Should It Be Replaced?
The answer depends on the severity and spread of the damage. Minor surface cracks may be addressed with patching, grinding, and a fresh topcoat. However, deep or widespread cracking often requires a more thorough approach.
Here’s a breakdown of options:
Surface Repairs:
- Ideal for hairline or localized cracks
- Involves cleaning, filling, and recoating the affected area
- Cost-effective but not ideal for long-term damage
Full Resurfacing:
- Needed when cracks are deep, widespread, or accompanied by bubbling and peeling
- Involves grinding down the old coating, addressing slab issues, and installing a new multi-layer system
- A long-term solution that restores the floor to like-new condition
At Kongcrete Coatings, we perform a full assessment before recommending a solution. We use industrial-grade epoxy and polyaspartic systems engineered for Orlando’s conditions.
Why It’s Important to Act Fast
Waiting too long to fix cracks means exposing your slab to further risks:
- Moisture can penetrate the surface, leading to mold or mildew
- UV exposure may worsen discoloration and further weaken the surface
- Dirt and debris collect in cracks, making them harder to clean and worsening the damage
- Safety hazards increase with every inch that the crack widens
Especially in high-use areas like garages or commercial floors, delaying repairs can lead to lost function, slip hazards, and even liabilities.
How to Prevent Future Cracks in Your Epoxy Floor
If you’re investing in repairs or a full replacement, you’ll want to make sure the new system is built to last. Here’s how to prevent cracking in the future:
- Moisture Testing: Always check MVER before installation
- Use a Vapor Barrier: Particularly in older homes or slab-on-grade buildings
- Choose a Flexible System: Epoxy with a polyaspartic topcoat allows for expansion without cracking
- Avoid DIY Kits: They often lack the chemical composition and adhesion strength for Florida’s climate
- Hire Experienced Installers: Choose a team that grinds, profiles, and seals correctly every time
Kongcrete Coatings follows these practices as standard protocol. We don’t guess: we test, prep, and protect every inch of your floor.
When to Call the Professionals
If you’re unsure whether your floor is showing early signs of failure, it’s best to get a professional opinion. A qualified flooring contractor will:
- Inspect the floor for moisture intrusion and substrate damage
- Determine the type and cause of cracks
- Recommend the most cost-effective solution based on your space and needs
