Decorative flake
Vinyl chips broadcast into a wet base coat and sealed. The texture adds grip and hides dust, which is why it dominates residential garages.
Flake floorsEpoxy flooring in Phoenix, explained by the people who install it
Epoxy is a family of products, not one material. Which formula goes down, how thick, over what prep and under which topcoat decides whether a floor still looks right in ten summers or starts lifting in two.

What epoxy flooring actually is
An epoxy floor is a two-part thermoset coating. A resin and a hardener are mixed on site, and the chemical reaction between them produces a hard plastic layer that bonds to the concrete underneath. Unlike paint, which dries as a solvent or water evaporates, epoxy cures. That reaction is what gives it strength, and it is also why mixing ratios, temperature and timing matter so much on installation day.
In practice, "epoxy flooring" is shorthand for a whole system. A typical floor has a primer that penetrates the prepared concrete, one or more body coats that build thickness and color, an optional decorative layer such as flake, quartz or metallic pigment, and a topcoat that takes the wear. Some of those layers are epoxy. Others, especially the top layer on floors that see sunlight, are better as polyaspartic or polyurethane.
So when you compare quotes, the useful questions are not just "is it epoxy?" but how the concrete will be prepared, what each layer is made of, how many coats there are and roughly how thick the finished system will be. Those details are where good floors and short-lived floors part ways.
Types of epoxy and where they belong
Each formulation has a job. Most professional floors use more than one of them, layered for a specific purpose.
| Formulation | What it does well | Limitations | Where we use it |
|---|---|---|---|
| 100% solids epoxy | High build, strong adhesion, very low odor since there is nothing to evaporate | Short working time in heat; ambers in UV | Base and body coats, metallic floors, self-leveling systems |
| Penetrating epoxy primer | Low viscosity soaks into the ground profile and locks the system to the slab | Thin film; not a wear layer | First coat on most interior systems |
| Moisture-tolerant epoxy | Tolerates higher vapor emission from the slab than standard primers | Adds cost; still has limits | Older on-grade slabs, slabs without vapor barriers, industrial floors |
| Water-based epoxy | Breathable, easy to apply, low odor | Thin build, lower chemical and abrasion resistance | Light-duty areas and some sealers |
| Novolac epoxy | Higher chemical and acid resistance | More brittle; specialty pricing | Battery rooms, labs, chemical containment, some food areas |
The topcoat on garage, patio and sun-exposed floors is usually polyaspartic or aliphatic polyurethane rather than epoxy, because standard epoxy yellows when UV light reaches it.
Finishes you can choose from
The chemistry underneath can be similar. The look on top changes a lot.
Metallic
Metallic pigments in a clear, self-leveling body coat create depth and movement. Every floor is different, and it reads as a design feature.
Metallic floors
Solid color
A clean, uniform look for shops, commercial back rooms and minimalist interiors. Easy to line-stripe and simple to keep consistent across large areas.
Concrete coatingsHow the layers stack up
Switch between three of our most common systems to see what each layer does. Thickness and coat count change with the space, but the logic stays the same: bond first, build second, protect last.
The most requested garage system in the Valley. Texture hides dust and gives tires something to grip.
- Clear topcoat
Polyaspartic or polyurethane. Takes the UV, the scuffs and the chemicals.
- Vinyl flake broadcast
Thrown to refusal, then scraped and vacuumed so only locked-in chips remain.
- Pigmented base coat
Epoxy or polyaspartic that the flake falls into while it is still wet.
- Penetrating primer
Soaks into the ground profile and becomes part of the slab surface.
- Ground concrete (CSP 2–3)
Diamond-ground to open the pores. Cracks and spalls filled before anything goes down.
A thicker, self-leveling build. More prep time and more cure time, and the result is one of a kind.
- High-gloss or satin topcoat
Protects the metallic layer from abrasion and UV yellowing.
- Metallic epoxy body coat
100% solids epoxy with metallic pigment, worked by hand while it levels.
- Tinted epoxy ground coat
Sets the background color the metallic movement shows against.
- Primer and crack treatment
Moisture-tolerant primer; cracks routed and filled flush.
- Ground concrete
Flat matters more here than anywhere: high spots telegraph through a metallic floor.
Faster cure and better UV stability than standard epoxy. Usually walkable the same evening.
- Polyaspartic clear coat
UV-stable and non-yellowing. Cures in hours instead of days.
- Flake or solid color
Same decorative options as an epoxy system.
- Polyaspartic or polyurea base
Applied in smaller batches because it sets quickly, especially in summer heat.
- Ground concrete
Prep is identical. Fast chemistry never makes up for skipped grinding.
Why epoxy behaves differently in Phoenix
Epoxy cures faster as temperature rises. A product with a comfortable working window on a 70-degree morning can begin to set in the bucket on a 105-degree afternoon. In summer we start early, mix smaller batches, keep material out of the sun and check slab temperature with an infrared thermometer before each coat.
Heat also affects the finished floor. Standard epoxy softens slightly at high temperatures, and a slab baking in afternoon sun near an open garage door gets hot. Pairing an epoxy base with a harder, UV-stable topcoat handles both the heat and the light.
Then there is moisture. Many older Valley homes were built on slabs without a vapor barrier underneath, and moisture vapor moving up through concrete can push a coating off from below. Testing before we coat tells us whether a standard primer is fine or a moisture-mitigating primer is needed.
- Early-morning starts and small batches in summer
- Slab temperature and dew point checked before each coat
- Moisture testing on older and on-grade slabs
- UV-stable topcoats wherever daylight reaches the floor
From bare slab to finished floor
The steps below describe a standard interior or garage system. Industrial and metallic floors add steps of their own, which are covered on their dedicated pages.
Assess the slab
Moisture readings, hardness checks, crack mapping and a look for sealers, paint or adhesive residue.
Grind and vacuum
Diamond grinding with dust extraction to open the pores and remove weak surface paste.
Repair
Cracks, pits and spalls are filled with epoxy or polyurea repair material and ground flush.
Prime
A penetrating primer wets out the profile and gives every later layer something solid to grab.
Build and decorate
Body coats go down at measured coverage, with flake, quartz or metallic added if the design calls for it.
Topcoat and cure
A clear protective coat, texture if needed, and a cure schedule you can plan around.
Is epoxy the right call for your floor?
Epoxy-based systems suit most concrete floors, but not every one. These are the questions that settle it.
- Is the slab interior, or does it get direct sun?
- Will vehicles park on it, and how hot will the tires be?
- Are there chemicals involved beyond household cleaners?
- Does the space need to return to service the same day?
- Is there an existing coating, sealer or tile adhesive on the slab?
- Has the slab shown signs of moisture, efflorescence or past coating failure?
- Do you want texture for grip, or a smooth decorative finish?
- Is there a deadline, such as a move-in date or an HOA window?
Questions we hear about epoxy flooring
How thick is a professional epoxy floor?
It varies widely by system. A residential flake floor typically builds to roughly 15 to 25 mils (thousandths of an inch) including the broadcast, while self-leveling and metallic floors are usually thicker. Heavy industrial systems can be measured in eighths of an inch. Your proposal should state the system, the coats and the expected thickness so you can compare quotes fairly.
Does epoxy smell during installation?
The 100% solids epoxies we use for most base coats have very little odor. Some primers and topcoats, especially solvent-based ones, have a noticeable smell for a few hours. For occupied homes we plan ventilation and choose low-odor products where the system allows.
Can epoxy go over an existing coating?
Sometimes, if the old coating is well bonded and compatible, it can be ground and recoated. If it is peeling, bubbling or of unknown chemistry, it needs to come off first. Coating over a failing layer only puts a new floor on top of an old problem.
Will an epoxy floor crack if the slab cracks?
A coating is only as stable as the concrete under it. If the slab moves at a crack, the floor above can show it. Repairing cracks before coating helps, and honoring control joints instead of filling them rigidly gives the slab room to move. We will point out cracks that are likely to stay active so there are no surprises.
How do I clean an epoxy floor?
Dust-mop or blow off grit regularly, since sand acts like sandpaper underfoot. For washing, a pH-neutral cleaner and a soft mop or deck brush are all most floors need. Avoid strong acids, citrus degreasers left to sit, and abrasive pads on high-gloss finishes.
Is epoxy flooring expensive?
Cost depends on square footage, slab condition, the amount of repair needed and the system you choose. A full-flake garage, a metallic living room and an industrial floor are priced very differently. We give a written estimate after seeing the slab rather than quoting blind over the phone.
