You don’t need to tear everything out—just do it right. Here’s when epoxy can go over existing concrete, and what to expect from the process.
We get this question a lot—and for good reason.
If your garage, patio, or shop floor is starting to look rough, but you don’t want to tear everything up and start from scratch, you might be wondering:
Can I just epoxy over the old concrete I already have?Short answer? Yes—but only if it’s done right.
At Surface & Concrete Design Solutions, we’ve helped hundreds of Central Florida homeowners and business owners upgrade their existing surfaces without full replacements. Let’s walk you through when it works, when it doesn’t, and how to make it last.
✅ Yes, You Can Epoxy Over Old Concrete—If It’s Structurally Sound
Epoxy coatings are only as strong as the surface they bond to. So while age doesn’t automatically disqualify a slab, the condition of the concrete is everything.
Here’s what we look for during your free consultation:
No major structural cracks or crumbling
No signs of ongoing moisture issues (efflorescence, peeling paint, mold)
A level surface free from major spalling or pitting
Solid, stable substrate beneath the top layer
If your slab passes the test, you’re good to go. We’ll grind, clean, patch, and prep the concrete for a strong, lasting bond.
⚠️ When You Can’t Epoxy Over Concrete
Some floors aren’t quite ready—and that’s OK. That doesn’t mean you need to rip everything out. It just means a little restoration needs to happen first.
Here are a few red flags that require repair or resurfacing before epoxy:
Heaving or settling (uneven sections of the slab)
Active moisture problems, such as ground water seeping in
Flaking or spalling, where the concrete is breaking away in layers
Coatings or sealers that haven’t been properly removed
In these cases, we often recommend either:
Concrete resurfacing with a microtopping or overlay
Moisture mitigation systems
Or, in rare cases, slab replacement for extreme damage
The good news? We handle all of this. You won’t need multiple contractors or companies.
🔧 Our Epoxy Over Concrete Process (The Right Way)
We don’t cut corners—because if we did, your floor would peel in 6 months.Here’s what we do instead:
Mechanical GrindingWe diamond grind the surface to open pores and remove existing coatings or contamination.
Moisture TestingWe test the slab for vapor emission that could break the epoxy bond from underneath.
Repairs & PatchingCracks, pits, or surface damage are filled and leveled for a seamless finish.
Professional Coating SystemWe apply a high-grade epoxy base, your chosen color or flake, and a durable topcoat that’s UV-resistant and built to last.
Curing & CleanupAfter 24–72 hours (depending on traffic type), your floor is ready for action.
💡 Why It Pays to Restore Instead of Replace
Many of our clients are surprised at how affordable and impactful epoxy is—especially compared to ripping out and re-pouring concrete.
Epoxy over existing concrete offers:
Lower cost than demolition/replacement
Faster turnaround (often 2-3 days from start to finish)

Added durability and chemical resistance

You’re not just refreshing the surface—you’re strengthening and sealing it for years of use.
