Polyaspartic, not big-box epoxy.
The single biggest decision that determines whether your floor lasts 3 years or 20 isn’t color or finish – it’s chemistry. This page is the plain-English breakdown of what we install on every job, and why.

A coating chemistry built for slabs that work hard.
Polyaspartic is a two-part coating in the aliphatic polyurea family. In plain English: it’s the resin chemistry the U.S. military spec’d for concrete that has to take a beating – hangars, motor pools, aircraft maintenance bays. The same chemistry now sells on residential and commercial floors.
What makes it different from epoxy:
- Flexibility: stays elastic instead of brittle. Slab moves with temperature – polyaspartic flexes with it. Epoxy cracks.
- UV stability: won’t yellow or chalk under San Diego sun. Epoxy yellows within a year or two outdoors.
- Cure speed: 90 minutes to set, full cure in 24 hours. Epoxy takes 3-7 days.
- Chemical resistance: shrugs off brake fluid, motor oil, hydraulic fluid, gas, solvents, deicer salt. Epoxy etches under aggressive chemicals.
- Abrasion resistance: 6-8x harder against scratch and gouge than standard epoxy.
The trade-off: polyaspartic costs more per gallon and requires faster, more skilled application. You can’t roll it on at your own pace – the working window is 30-45 minutes. That’s why DIY kits are still mostly epoxy, and why a polyaspartic install needs a trained crew.
What goes on your floor, layer by layer.
The system that lasts 20+ years isn’t one product. It’s five.
Layer-by-layer breakdown
Substrate
Primer
Base coat
Broadcast
Topcoat
Why 5 layers? Each one does a job no other layer can. Skip primer and the coating loses chemical bond. Skip broadcast and the floor reads as cheap (and slip-tested grip drops). Skip topcoat and the color layer takes abrasion instead of the sealer.
Why diamond-grind? Polyaspartic forms its bond through mechanical grip on opened concrete pores. Acid-etch softens the surface chemically but doesn’t open it mechanically. Grinding is the only prep that produces the substrate polyaspartic was designed for.
Why broadcast to refusal? Partial chip patterns look like a sales sample, not a finished floor. Hand-broadcasting until the surface won’t accept more chips creates a uniform decorative carpet AND adds the slip resistance that makes the floor safe wet.
Total dry film thickness: 22-30 mils. For reference, a DIY epoxy kit applies 3-5 mils. That’s a 5-10x material difference under your feet.
The real comparison.
Cure & installation
Epoxy: 3-7 days
Epoxy: 2-3 workdays
Epoxy: 4-6 hours
Performance over time
Epoxy: yellows within 1-2 yrs outdoors
Epoxy: brittle, cracks with slab movement
Epoxy: 5-10 yrs residential
