When homeowners call us, the first thing they almost always ask is "is it epoxy?" The honest answer is yes, partly — there's epoxy in our system, but only as the base coat. The real workhorse is what we put on top of it.
The short version
Epoxy is great at bonding to concrete. It's terrible at standing up to UV, hot tires, and time. So we use it for what it's good at — gluing the system to your slab — and use polyaspartic for everything that matters above it.
Epoxy alone yellows in a year, peels under hot tires, and chalks under UV. Polyaspartic doesn't. End of story.
What polyaspartic actually is
Polyaspartic is a sub-class of polyurea — a two-part resin developed in the late '90s, originally for bridges and pipelines. It cures fast (we walk on a fresh top coat in 4–6 hours), it's UV-stable, and it's chemically resistant to almost everything you'd find in a residential garage.
Key properties:
- UV-stable — won't yellow, won't chalk.
- Fast cure — install in a day, drive on it the next morning.
- Chemical-resistant — oil, gas, brake fluid, road salt — no issue.
- Flexible — small slab movement won't crack the coating.
Why "hot-tire pickup" is the test
The single most common failure mode for a cheap garage coating is what the industry calls hot-tire pickup: you pull into your garage on a 95° Boise afternoon, your tires are hot, and the softening agents (plasticizers) in your tires actually melt into a poorly-formulated coating. When the rubber cools, it pulls a piece of your floor up with it.
Polyaspartic doesn't have the same softening response, so the bond between rubber and floor never forms. Tires roll on, tires roll off, floor stays put.
Where epoxy fits in our system
We still use a high-solids epoxy as our base coat — it bonds to freshly-ground concrete better than anything else on the market, and the pigment in it provides the "color" of the floor under the flake. But the moment that coat is wet and the flake is broadcast into it, we move on. Top coat is 100% polyaspartic.
A four-coat system, in order
- Diamond grind to open the concrete pores
- Pigmented 100%-solids epoxy primer (this is where the color lives)
- Full vinyl flake broadcast to refusal
- Two polyaspartic top coats — UV-stable, chemical-resistant, ready to drive on the next morning
What this means for your warranty
Most epoxy-only floors come with a 1–5 year warranty, often with a long list of exclusions. Our polyaspartic-topped system carries a 15-year warranty against peeling, bubbling, and hot-tire pickup. We can write that warranty because we've watched our earliest installs go past year seven without a single failure.
The chemistry is settled. The labor is the variable. We do the labor the same way every time.
