Our team provides true two-part epoxy base coats in place of the one-part floor paint sold for do-it-yourself painting, delivering a floor that grips its slab for both residential and commercial projects. We test the slab for moisture and check the ground surface profile before the base coat is mixed, and the reading goes on your written scope, because adhesion is decided in the prep rather than in the painting.
From routing out a cracked control joint and grinding off old peeling floor paint to broadcasting flakes into the wet base coat, our team handles every detail. Serving Rancho Cucamonga together with Fontana, Eastvale and Chino, we coat garages in the heat of an inland summer with products chosen for hot tires.
Why Rancho Cucamonga Elite Painting
No salesperson hands you to a stranger. The person who measures the job answers for it.
Most peeling garage floors in Rancho Cucamonga failed for one of three reasons: the product was not a real two-part epoxy, the concrete was never opened up to give it something to grip, or moisture coming up through the slab pushed it off. A prepared epoxy system addresses all three before the first coat.
Tires contain plasticizers that migrate to the surface when a tire is hot. On a soft coating they bond to the film, and as the tire cools and the car pulls away, the coating lifts with it. A car that has just come off the 210 in a hot-summer climate like this one is the worst case.
Many cans sold as epoxy floor paint are single-component, water-based acrylics with some epoxy added. They dry by evaporation rather than by a chemical reaction, and their low solids content cannot resist hot tires however well the floor was cleaned.
Concrete releases water vapor. When too much comes up under a coating, the result is blistering, adhesive failure and white efflorescence salts at the surface.
A trowelled garage slab is dense and smooth. Without a mechanical profile, a coating sits on top instead of keying into the surface.
An epoxy garage floor in Rancho Cucamonga is only as good as the slab prep, so the prep is measured, not guessed. These are the steps that come before any coating is mixed.
There are two recognized tests. ASTM F1869 seals anhydrous calcium chloride under a dome on the slab and weighs how much moisture it absorbs, which gives a vapor emission rate at the surface. ASTM F2170 places relative humidity probes in holes drilled into the slab, which reads the moisture inside it. The two measure different things and cannot be converted into each other; on a borderline slab, both are used.
The International Concrete Repair Institute grades prepared concrete on ten surface profiles, from CSP 1, nearly smooth, to CSP 10, very rough. Acid etching only reaches CSP 1, which suits thin sealers. A high-build epoxy system typically calls for CSP 3 to 5, which is why we diamond grind rather than etch, and why mechanical preparation is the industry's first choice.
Old floor paint is ground off completely, because a new coating bonded to a failing one fails with it. Cracks and chipped control joints are cleaned out and filled, then ground flush so they do not telegraph through the finish.
A slab that tests high for moisture is not the end of the job; it changes the system. Epoxy moisture control products are roller-applied barriers made for this, and some are rated for concrete at relative humidity up to 100 percent, bringing the vapor emission down to a level the coating above can tolerate.
Slabs run wet for known reasons: concrete placed without a vapor barrier underneath, too much water in the original mix, irrigation or a planter bed against the garage wall, or a plumbing leak. When the test reads high, we tell you what we found, add the moisture barrier to the written scope, and price it as its own line so you can see what it costs.
Skipping the test is how a coating that looked perfect on day one starts to blister along the wall months later.
A full-broadcast flake floor is built in layers, and each one has a job. Recoat windows and cure times follow the product data sheet for the system and the temperature in your garage, and they are written on the estimate rather than promised here.
The whole slab is diamond ground to the specified profile, including the edges, and the dust is vacuumed off.
Cracks, joints and spalls are filled and ground flush.
A two-part epoxy, resin and hardener mixed in the ratio the manufacturer specifies, is rolled onto the slab. The two parts react chemically into a hard thermoset film with strong adhesion.
While the base coat is still wet, decorative vinyl flakes are broadcast to rejection, meaning until the surface will not hold any more.
Once the base has cured, the floor is scraped to knock down raised flake edges, and the loose flakes are vacuumed away.
A clear topcoat locks the flakes in. Epoxy on its own chalks and yellows with sun and age, so garages with the door open to afternoon light get a polyaspartic or polyurethane topcoat for UV stability.
Every product we use has to meet South Coast AQMD Rule 1113, which limits the volatile organic content of architectural coatings sold and used in the district. We work from the product data sheet for the exact system on your floor and can give you a copy.
The same prepared system suits more than a family garage. Community managers with shared garages, rental owners between tenants and small shop owners with a concrete floor ask for the same moisture test and grind before a bid. Bigger slabs are measured by square foot and scheduled around the people who still need to use them.
An epoxy garage floor coating in Rancho Cucamonga is typically estimated at roughly $1,500 to $6,000, and the slab condition moves the price more than the size of the garage does. A clean, dry slab in a small garage sits at the low end; a large garage with old paint to grind off and a moisture barrier to add sits near the top.
Treat these ranges as estimates only; they can change with the slab, and the written quote we give after testing your floor sets the actual price.
The process
Four steps, and nothing is painted until you have approved the scope and the colors.
We walk the house or property with you, look at the stucco, the trim and the old coating, and note what the sun and the wind have done to each side.
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.
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.
We walk it again with you before we call it done, and touch up anything you point at.
Questions
A prepared two-part system on a ground, moisture-tested slab is built to avoid the causes that peel floor paint. The old paint is ground off completely first, because a new coating is only as strong as whatever it is bonded to.
No. Existing floor paint is removed by grinding down to sound concrete. Coating over it would tie the new floor to a film that is already letting go.
Not as the main prep. Acid etching leaves only the smoothest of the ten concrete surface profiles, while a high-build epoxy wants a rougher one, so we diamond grind the slab.
The test result goes on your written scope, and a moisture control coat is added under the epoxy as its own priced line. Coating a wet slab without one is how blisters appear later.
That depends on the system's product data sheet and the temperature in your garage, and the return-to-service time is written on your estimate. We do not guess at it on the phone.
Epoxy alone can chalk and yellow with UV and age. A polyaspartic or polyurethane topcoat is used where sun reaches the floor, which is most garages that sit open in the afternoon.
Cracks are cleaned out, filled and ground flush before the base coat, so most disappear under the flakes. A crack that is still moving in the slab can reappear, and we point those out at the walk.
Yes. We look at the slab, note any old coatings and cracks, and give you a written estimate; the moisture test result is added to the scope before work begins.
