Moisture
If the slab is holding too much moisture for a standard epoxy, we say so and recommend a moisture-tolerant primer or a different system, rather than coating and hoping.

About our epoxy garage floor coating
Our team provides moisture checks on every slab before coating, delivering a hard, cleanable garage floor for both residential and commercial projects. We write the grinding, the crack repair, the base coat, the flake and the top coat into a written scope, and the crew that grinds your floor is the crew that coats it, alongside any garage wall painting you add.
From filling a settlement crack and grinding off old sealer to coating a three-car garage wall to wall, our team handles every detail. Serving Riverside, Eastvale, Diamond Bar and Yorba Linda, we plan the job so the floor is back in use when the product data says it is ready.

Grinding and Prep
Most garage floor coatings that fail were applied to a slab that was not prepared. Epoxy grips concrete by keying into its surface, so the surface has to be opened up first. Mechanical grinding with a floor grinder creates an even concrete surface profile, a texture the coating can bond into, without the uneven results of an acid etch.
Grinding also removes what sits on top of the concrete and would otherwise sit under the coating: old paint, sealers, tyre marks, oil and the weak top skin of the slab. Oil stains that have soaked in are degreased and ground back. The dust is vacuumed off with the grinder's own collection and a final pass, because a dusty slab gives the coating something loose to stick to.
Edges, the step up to the house door and the area under the garage door seal are ground by hand, since a machine cannot reach them, and those are the places where a poorly prepared coating lifts first.
Moisture, Cracks and Old Coatings
Concrete looks dry when it is not. Moisture can rise through a slab from the ground below, and that vapour pushing up under a coating weakens its bond over time. A simple plastic sheet test, taping a square of plastic to the slab and checking for beads of water underneath, gives a first indication, and a meter reading is taken where the result is unclear.
Cracks and spalls
Hairline cracks, settlement cracks and small spalled areas are cleaned out and filled with a repair compound so they do not telegraph through the new floor. Control joints can be kept as joints or filled, which is decided with you.
Old coatings
A previous paint or coating that is peeling is ground off completely. Coating over a failing layer only gives the new floor a weak base.
Base Coat, Flake and Top Coat
A full flake floor is built in layers, each with its own job.
Base coat
A pigmented epoxy base is rolled onto the prepared slab. It bonds to the concrete and sets the background color.
Flake broadcast
While the base is still wet, colored vinyl flakes are broadcast across the floor, lightly for a speckled look or to full coverage for a stone-like finish. Flake also hides small imperfections in the slab and adds texture underfoot.
Top coat
After the excess flake is scraped and swept off, a clear top coat seals everything in. Polyaspartic chemistry, introduced in the early 1990s, is a common choice for top coats because it is tough and holds its clarity in sunlight, while some epoxy top coats can yellow over time where light reaches them. A solid-color floor skips the flake and uses a second pigmented coat or a clear coat over the base instead.
Choosing a Color and Flake Blend
The look of a garage floor comes down to two choices: the base color and how much flake goes on top of it.
Gray and tan bases are the most common because they hide tyre marks, dust and the fine sand that blows into an inland garage with the door open. Lighter bases brighten a garage used as a workshop or gym, and darker bases suit a showpiece garage where the floor is kept clean.
Flake blends mix two to four colors of vinyl chip. A light broadcast lets the base show between the chips for a speckled floor, while a full broadcast covers the base entirely and gives a more textured, granite-like surface that hides more. Full broadcast also adds a little more grip underfoot.
Samples are the only reliable way to choose, because chip blends look different on a screen and under a garage's own lighting. We bring sample boards to the walk so you can see each blend on the floor itself, in the light you will actually see it in, and the blend you pick is named in the written scope.
Heat, Hot Tyres and Cure
Garages here get hot in summer, and so do tyres after a drive. A hot tyre can soften a thin or poorly bonded coating and pull it off the slab when the car is parked, which is known as hot tyre pickup. It shows up most where the slab was not properly prepared or was still holding moisture.
The defences are the ones already described: a properly ground slab, a moisture check, a coating system built to the thickness the manufacturer specifies, and a top coat suited to vehicle traffic. Heat also shortens the working time of many floor products, so mixing and rolling are timed to the temperature in the garage on the day.
Walking on the floor and parking on it are two different milestones, and both depend on the product and the conditions. They are taken from the product's data sheet and written into your schedule, so you know when the garage is back in use.
Garage Floor Coating Cost
The floor area is the starting point, but prep drives the price as much as size. Removing an old coating, grinding off sealer, repairing cracks and spalls, treating a damp slab, the choice between a flake and a solid finish, and the top coat all move the number. Painting the garage walls and ceiling at the same time is quoted as its own line.
As a guide, an epoxy garage floor is typically estimated at roughly $1,500 to $6,000, from a single-car garage with a sound slab at the low end to a large garage with old coating removal and heavy repairs at the high end.
These figures are estimates, they are subject to change once the slab has been tested and inspected, and the written quote sets the final price.
Colors and Finishes
The process
How a Painting Job Runs
Four steps, and nothing is painted until you have approved the scope and the colors.
The walk
We walk the house or property with you, look at the stucco, the trim and the old coating, and note what the afternoon sun, the dry wind and the sprinklers have done to each side.
The written scope
You get the prep, the products, the colors and the dates in writing. For an association or a building, the scope is phased so residents and tenants know which day is theirs.
Prep, then paint
Washing, scraping, patching and caulking come first, because that is what the paint holds on to. Then primer where it is needed and the finish coats.
The final walk
We walk it again with you before we call it done, and touch up anything you point at.
Questions
Epoxy Garage Floor Coating: Common Questions
Will an epoxy garage floor peel?
Peeling almost always comes from poor preparation or moisture in the slab. Grinding, a moisture check and a coating built to the manufacturer's specification are what keep a floor bonded.
What is the difference between epoxy and polyaspartic?
Both are tough two-part coatings. Epoxy is often used as the base coat that bonds to the concrete, and polyaspartic is often used as the clear top coat because it handles sunlight and traffic well. Many floors use both.
Do I need flakes in my floor?
No, but most homeowners choose them. Flake hides dust and small slab flaws, adds texture underfoot, and gives a speckled or stone-like look. A solid color is cleaner looking but shows more.
Can you coat a garage floor that has oil stains?
Yes, after the stains are degreased and ground back. Deep oil contamination is ground out, because coating over oil is one of the main reasons floors lift.
How long before I can park in the garage?
It depends on the products and the temperature. Walk-on and drive-on times come from the coating's data sheet and are written into your schedule before the job starts.
Can you paint the garage walls at the same time?
Yes. Walls and ceilings are usually painted before the floor is coated, so drips land on the old slab rather than the new finish. It is priced as a separate line on the estimate.
Is the coating slippery?
A flake floor has natural texture. Where extra grip is wanted, an anti-slip additive can be mixed into the top coat, which we discuss when the finish is chosen.
Do you coat floors in shops or commercial garages?
Yes. Workshops and commercial garages are quoted by area, with the system chosen for the traffic and chemicals the floor will see.
Can the coating cover the garage step and the driveway apron?
The step up to the house door is coated with the floor. The driveway apron outside the door is a different exposure, with full sun and rain, so it is either left bare or quoted with a product rated for exterior concrete.
