What 1-Day Coating Companies Aren’t Telling You About Garage Floor Epoxy

New Jersey homeowners are seeing it everywhere: “Our coatings are 4 to 20 times stronger than epoxy!”. It’s a bold claim—but what these 1-day coating companies won’t tell you is that they’re not comparing themselves to the kind of garage floor epoxy we install at Garage Floor Coating of New Jersey. They’re comparing to low-end DIY kits that bear little resemblance to professional-grade systems.

Here’s what else they’re keeping from you:

They’re Not Talking About Our Garage Floor Epoxy

When they say “stronger than epoxy,” they’re not talking about 100%-solids, industrial-grade epoxy systems like ours. They’re referencing weak, water-based products from hardware stores.

We use:

• A 100%-solids garage floor epoxy primer that penetrates the concrete and complies with ASTM F3010 standards for moisture mitigation
• A full-flake broadcast layer for visual appeal and added thickness
• Two coats of polyaspartic topcoat for high UV, abrasion, and chemical resistance

What they use:

• A polyurea or polyaspartic hybrid applied direct to concrete (and they shouldn’t be applied direct-to-concrete, especially in the presence of moisture)
• One clear topcoat (often below 100%-solids)
• No moisture mitigation

“Stronger” Isn’t the Whole Story

Sure, they reference a lab test like Shore D hardness—but they leave out the other real-world factors that matter when it comes to long-term performance in New Jersey’s climate:

• Adhesion strength, so the floor stays bonded
• Moisture mitigation, so vapor doesn’t cause bubbling or delamination
• System thickness, for wear resistance over time
• Chemical and UV protection, especially important in exposed garages

Our garage floor epoxy system is built to outperform—not just look good on paper.

They Don’t Prevent Moisture-Related Failures

The biggest threat to floor coatings? Moisture vapor rising through the slab. Even when companies test for moisture, most 1-day systems skip the primer that actually prevents damage.

We don’t. Our epoxy base coat stops vapor before it can wreak havoc. That’s how we offer a lifetime warranty against moisture-related coating failure—something they simply can’t promise.

They Finish Fast Because They Cut Corners

To install a system in one day, they leave out:

• The epoxy primer
• The second polyaspartic topcoat
• Buffing the flake layer before sealing

It may be fast, but it’s not built to last.
