Polyaspartic Garage Floor Coatings in Southern California
Polyaspartic is the coating we finish almost every garage floor with, and for good reason in Southern California: it won't yellow in sun, it shrugs off hot tires, and it cures in hours instead of days. We install Kretus polyaspartic systems on garages across the Inland Empire, Orange County and LA.
Polyaspartic is a fast-curing aliphatic polyurea coating. On a garage floor it gives you a UV-stable, chemical- and hot-tire-resistant surface that can often be installed in a day. Our standard garage system is diamond grind, repair, base coat, full flake broadcast and a polyaspartic clear topcoat, at about $5.50–$6.50 per sq ft plus prep.
Why polyaspartic works in a SoCal garage
- Sun and heat. Polyaspartic's aliphatic chemistry doesn't amber under UV, so a garage that sits open to the afternoon sun keeps its color. Bare epoxy yellows.
- Hot tire pickup. After a summer drive on the 15 or the 91, tires are hot enough to soften weaker coatings and lift them when you pull out. Polyaspartic topcoats handle that heat far better.
- Chemicals. Oil, gas, brake fluid and pool chemicals wipe up instead of staining.
- Speed. Short recoat windows mean fewer days with your car in the driveway.
Polyaspartic vs epoxy, at a glance
| Polyaspartic | Epoxy | |
|---|---|---|
| UV / sun | Stays clear and color-stable | Ambers without a UV topcoat |
| Recoat time | About 1–36 hrs depending on grade | Typically overnight |
| Hot tires | Strong resistance | Weaker, especially thin or DIY coats |
| Working time | Short (5–30 min) | Longer, more forgiving for DIY |
| Best role | Topcoat, or full system | Base coat, metallic, heavy build |
That's why our standard build is a hybrid: base coat for bond, flake for texture and hide, polyaspartic on top. More detail in Epoxy vs Polyaspartic.
The Kretus numbers
We install and stock Kretus polyaspartics. Their published data, by grade:
| Grade | Working time | Recoat | Foot traffic | Full cure |
|---|---|---|---|---|
| EZ (standard) | 15–30 min | 6–36 hrs | 24–36 hrs | 5–7 days |
| FAST | 15–25 min | 3–24 hrs | 24 hrs | 3–5 days |
| XFC (extra fast) | 5–10 min | 1–6 hrs | 12 hrs | 3 days |
Ranges combine the versions Kretus publishes for each grade (72, 85 and 92 Low Odor). The full table and what "one-day" really means is in One-Day Garage Floors: What "Same-Day Install" Actually Means.
How we install a polyaspartic garage floor
- Moisture check and inspection. Fast systems leave no room for a wet slab. If readings are high we change the primer or the schedule.
- Diamond grind with HEPA extraction to remove stains, sealers and old coatings and open the surface.
- Repair cracks, joints and spalls with polyurea or epoxy patch, shaved flush.
- Base coat, pigmented to match your flake blend.
- Full flake broadcast to refusal, then scrape and vacuum.
- Polyaspartic clear topcoat, with anti-slip additive if you want extra grip.
Cost
Flake garage floors with a polyaspartic topcoat run about $5.50–$6.50 per sq ft plus $1–$3 per sq ft prep, or roughly $2,600–$3,800 for a typical 2-car garage. Full polyaspartic builds, exterior work and slabs with heavy repair are quoted individually. Full breakdown: epoxy flooring cost in California.
Contractors and DIYers: Kretus Polyaspartic (72, 85 and 100% solids, fast or slow cure) and E-FLO PA100 are on the shelf in Corona, along with Torginol flake and anti-slip additive. Call ahead and we'll have it pulled.
Polyaspartic garage floor FAQ
Is polyaspartic better than epoxy for a garage floor?
For the top layer, usually yes. Polyaspartic is UV-stable so it won't amber in sun, it handles hot tires and temperature swings better, and it cures much faster. Epoxy still makes an excellent base coat. That's why most of our garage floors are a hybrid: a base coat for bond and build, then a polyaspartic clear topcoat. Our epoxy vs polyaspartic comparison goes deeper.
Can a polyaspartic garage floor really be done in one day?
The installation can, on the right slab. Fast-cure polyaspartics have recoat windows of a few hours, so base, flake and topcoat can go down in one visit. The cure is a separate number: Kretus rates its polyaspartics for foot traffic in roughly 12 to 36 hours and full cure in 3 to 7 days depending on the grade. We won't rush a one-day install onto a slab with a moisture problem or heavy repairs.
How long does a polyaspartic garage floor last?
A properly installed polyaspartic flake floor on a ground, sound slab is a long-term floor for a residential garage. The biggest factors are surface prep, slab moisture and film thickness, not the brand on the bucket. Most failures we're called to fix trace back to a floor that was never ground.
How much does a polyaspartic garage floor cost?
Our full-broadcast flake garage floors finished with a polyaspartic clear topcoat are quoted at about $5.50 to $6.50 per sq ft, plus $1 to $3 per sq ft for grinding and repair. A typical 400 sq ft 2-car garage lands around $2,600 to $3,800. Full polyaspartic builds and heavy-repair slabs are quoted after we see the floor.
Is polyaspartic slippery when wet?
Any smooth, glossy coating can be slick with water, oil or dust on it. A full flake broadcast already adds texture, and we can add an aluminum oxide anti-slip additive to the topcoat for more grip. See our guide to no-slip garage floors.
Can I buy polyaspartic and install it myself?
Yes. We stock Kretus Polyaspartic and E-FLO PA100 polyaspartic topcoat at our Corona counter. Polyaspartic has a short working time, so plan small batches and an extra set of hands, and grind the slab first. Our 2-day class covers the full install if you want to learn it hands-on.
