When you get competing quotes for a garage floor coating, most contractors will tell you they install a 3-coat polyaspartic system. Some of them are telling the truth. Most of them aren’t.
The difference between a true 3-coat system and the 2-coat shortcut that’s become standard in this industry isn’t just a number. It’s the reason floors peel. It’s the reason warranties get denied. And it’s the reason we’ve spent 16 years installing floors the way we do — with three full coats of polyaspartic resin, none of which is the flake.
We have been asked about our process for installing Polyaspartic coating and specifically about why we use a 3 coat process instead of two when installing your floor coating. Sometimes the 2-coat process is also referred to as 1-day coating.
Polyaspartic coatings are becoming increasingly popular for their durability and aesthetic appeal. Many companies in the Colorado Springs area are now offering a 2 coat system, where they broadcast or throw the flake into the first coat of a rolled-on floor. They will tell you it is the same, but it is not. We do not recommend it, and we do not use this process. Don’t be fooled when they say they use a 3 coat system, and count the flake as a coat. We don’t do that – you get 3 layers of coating, in addition to the flake.

Three coats are actually better than two
What “3 Coats” Actually Means — and Why It’s Being Misrepresented
Here’s what a legitimate 3-coat polyaspartic installation looks like:
- Coat 1 — Base coat (primer). Applied directly to the diamond-ground concrete. This is the bonding layer. It needs to soak into the open pores of the concrete undisturbed — no flake, no shortcuts.
- Coat 2 — Color coat. Applied over the cured base. The decorative flake is broadcast into this coat while it’s still wet, then the excess is swept off after it cures.
- Coat 3 — Polyaspartic topcoat. The protective finish layer. UV-stable, chemical-resistant, and the coat that determines how long the floor performs.
What most 2-coat contractors do instead: they skip the dedicated base coat and broadcast the flake directly into the first coat of resin. Then they apply a topcoat. Two coats total — but they call it three by counting the flake broadcast as a separate step.
That’s not a 3-coat system. And it’s not just a technicality. There’s a specific reason it causes floors to fail — and it comes down to surface tension.
The Science Behind Why 2-Coat Systems Fail
When polyaspartic resin is rolled onto concrete, surface tension is present in the wet film — the same phenomenon you see when water beads on a surface. For the coating to bond properly, that surface tension needs to stay low enough that the resin can soak into the millions of microscopic pores opened up by diamond grinding.
When a contractor broadcasts decorative flake directly into that first wet coat, the chips physically pull the resin toward them. This increases surface tension and prevents the resin from penetrating the concrete the way it needs to. The coating cures sitting on top of the floor rather than bonded into it. That’s what causes peeling and delamination — not a product failure, but an installation failure.
This is documented by Slide-Lok, whose products we use exclusively. Slide-Lok’s formulations include specific additives designed to manage and release surface tension during installation — but only when the system is applied correctly, with a dedicated base coat applied before the flake is introduced.
A 2-coat contractor using the same Slide-Lok label doesn’t get the same result if the process is wrong. The product is only as good as the installation sequence behind it.

Why Most Contractors Do It Anyway
The 2-coat process is faster and cheaper to install. Broadcasting the flake into the base coat saves one full product coat and cuts labor time — which is how some contractors can offer a same-day installation at a lower price point. That’s the business model, and it’s a legitimate one if the customer understands what they’re getting.
Most don’t. Because most contractors don’t explain any of this — they just say “3-coat system” and move on.
The floor will look identical on day one. The difference shows up in year two or three when the coating starts to lift at the edges, bubble in traffic areas, or delaminate under hot tires. By then, the contractor is long gone and the homeowner is looking at removal costs on top of a new installation.
We’ve been called in to remove and redo those floors. It’s not a rare situation — it’s one of the most common jobs we get.

Why Our Process Is the Only One We’ll Warranty
The residential lifetime warranty we offer against peeling and delamination isn’t a marketing statement — it’s a direct consequence of how the floor is built. We can offer it because we know the base coat had no flake interference, the resin bonded into the concrete the way it’s supposed to, and the surface tension was managed correctly at every stage.
A 2-coat installation doesn’t qualify for that warranty. Not because we won’t cover it — but because we won’t install it.
Every floor we put down uses the same 3-coat sequence, the same Slide-Lok products, and the same diamond-ground surface preparation. That consistency is what 1,000+ installations and a 5.0 rating are built on.
