Garage floors, polished concrete and commercial coatings, on slabs we test before we quote.
Colton Epoxy Flooring has spent more than twenty years putting resinous coatings and polished finishes on concrete in Colton, California, and across the San Bernardino Valley. We coat garage floors, resurface and polish concrete, and install commercial epoxy flooring in the kitchens, warehouses, plants and clinics that keep this city working.
That work starts with the slab that is already there, and here that matters more than most places. Nearly three in ten Colton homes were built before 1960 and eight percent predate 1940, while the largest single bloc went up in the 1980s. A pre-war detached garage off a South Colton street and an attached two-car bay on the north side are not the same job, and quoting them the same way means guessing on one of them.
So we test first and order second. A moisture reading, a look at whatever is already bonded to the slab, and a straight answer about whether a coating belongs on that floor come before anyone talks about color.

We have been coating concrete in this valley for more than twenty years, long enough to have gone back to floors we put down early and seen what held. That is the only useful kind of experience in this trade, and it is why we argue about preparation more than product.
Every slab is moisture tested before a single pail is ordered, not after a coating starts lifting. In a city where roughly four in ten homes predate 1970, that reading is the difference between a floor and a callback, because vapor moving up through an unprotected slab pushes a sound coating off the concrete rather than failing the coating itself.
We open every floor with diamond grinding or shot blasting to a measured ICRI CSP profile, never with an acid etch. Acid softens the surface and leaves residue that a resin bonds to instead of bonding to concrete, so the floor lets go in sheets a year later rather than staying keyed into a profile that holds it.
No two garage generations here take the same scope. An attached 1980s tract bay needs joint fill, oil remediation and hot-tire-resistant chemistry; a pre-war detached garage on its original slab usually needs moisture testing and movement repair first, so we specify and price them separately rather than running one template across the whole city.
Colton sits inside the South Coast Air Basin, where SCAQMD Rule 1113 sets Floor Coatings at 50 grams per liter and Industrial Maintenance Coatings at 100, treating the two as mutually exclusive. We confirm which category your building falls under before quoting, so the product on your floor is legal to apply there rather than carried in from a looser district.
Every return-to-service time we quote comes off the actual slab temperature and dew point on the day, not a label average. Pot life on a common system runs about 60 minutes at 55 degrees and collapses to roughly 20 minutes at 95 degrees, so a summer afternoon in an uninsulated garage changes the working window rather than leaving it as printed.
An epoxy garage floor is a system rather than a product: preparation, repair, a primer, a body coat, usually a flake or quartz broadcast, and a clear topcoat. We walk the slab, test it, grind it open, fix what grinding exposes, then build the film in coats with published recoat windows. A cheaper quote almost always means a layer is missing.
The tell is the garage rather than the house. The 1980s and 1990s stock is a conventional attached two-car bay on a slab 25 to 45 years old; the pre-1960 stock, roughly three in ten homes, is often a narrow single-car or shallow garage, frequently detached on its own slab. We identify which you have on the first visit, because prep, risk and price all move with it.
The largest bloc of Colton housing went up in the 1980s, putting many attached tract garages at 35 or more years of service. What we find is predictable: control-joint cracking, lipping at the door threshold, edge curling, decades of oil under where the car sits, and hot-tire pickup where a one-part paint let go. That predictability keeps scope and price steady.
Around the original downtown and through South Colton the garages get older and smaller, and about eight percent of the city’s homes predate 1940. Those slabs went down before under-slab vapor retarders were routine and sometimes over uncontrolled fill, so they can carry a moisture problem and a movement problem at once. We say plainly when a slab needs repair rather than a coating.
A garage holding thirty years of storage has to come out completely, because grinding throws dust everywhere and the floor has to be reachable wall to wall. We agree in writing who moves what before the day, and will do the moving as part of the job where that suits you. Nothing stalls a floor like finding the far third still full at 7:00 a.m.
We use the ASTM F1869 calcium chloride test to read moisture vapor emission rate at the surface and the ASTM F2170 in-situ relative humidity probe to read the slab at depth, because those answer different questions. Threshold numbers for both live in ASTM F710 rather than in the test methods. The ASTM D4263 plastic sheet test is asymmetric: a positive result fails a slab, a negative one proves nothing.
Concrete leaves the trowel closed, and a sealed or hard-troweled surface gives a resin almost nothing to key into. We grind with a diamond segment bond chosen against your slab’s hardness, up to the ICRI CSP profile the system calls for, under continuous HEPA dust extraction. A coating over unopened concrete is bonded to the surface film, not the floor.
Grinding exposes what the old floor was hiding. We fill control joints with a semi-rigid filler so the joint keeps working without the coating bridging and cracking, patch spalls and edge breakdown, and treat oil-saturated concrete before priming, because oil soaked into a slab bleeds back through anything laid over it. That is scoped and priced with the floor rather than raised halfway through.
The edges decide whether a garage floor looks finished or looks poured on. We cut a clean termination at the door threshold, carry the coating into the step-down where there is one, and hand-grind and hand-cut the perimeter with an edger so the film reaches the wall rather than fading out short of it. It is the detail a homeowner sees every time the door goes up.
How a floor failed tells us why, before anything is tested. A coating lifting in broad sheets with clean concrete underneath failed at the bond, which points at preparation; a film peeling with concrete still stuck to its back failed the slab instead. Blisters in a scattered field point at moisture, and tire-shaped patches at heat and plasticizer. The pattern decides what we test for.
Blistering is usually vapor pressure finding the weakest point in an impermeable film, which is why it appears in fields rather than at edges. We cut and lift a blister, read what is underneath, then run the numbers rather than assuming. Where readings come back high, the answer is a barrier primer sized to the number, or not coating that slab yet.
Taking off a consumer kit is harder than starting from bare concrete, and homeowners are consistently surprised by that. The film is thin, tough and unevenly bonded, so it loads tooling and tears rather than cutting cleanly. We usually shear it off with PCD tooling before switching to a grit sequence to profile what is underneath.
A one-part latex or alkyd garage paint is not a coating system, and on a slab with no vapor retarder under it the outcome is close to certain. It has little chemical resistance, no meaningful build and no way to handle vapor drive, so it lifts under hot tires and blisters wherever moisture moves. Removing it is scope, not a courtesy.
A slab that dusts under a broom has a weak surface layer, and a coating over it is only as attached as that powder. A previously applied sealer is the opposite problem: an intact film stopping any resin from reaching concrete. Both are diagnosed by grinding a test patch rather than by looking, and both are solved by taking the surface back to sound material.
These three do different work, and picking wrong costs a day. Diamond grinding profiles and levels, which is what most residential garages need. Shot blasting opens a deeper, more uniform profile fast across large commercial areas, though it will not reach edges. PCD tooling shears a coating off rather than abrading it, making it the right first pass on a failed film.
The rule reads backwards until you have watched it: hard concrete takes a soft bond and soft concrete takes a hard one. A soft matrix keeps wearing away to expose fresh diamond on a slab that would otherwise polish the segment smooth. Get it wrong and you either burnish the floor or destroy segments in an afternoon.
Most warranties in this trade exclude moisture-related failure, which is awkward given that moisture is the dominant way these floors fail. We would rather say that out loud than sell coverage that quietly omits the likeliest problem. It is also the argument for testing before purchase: a documented reading and a barrier primer sized to it is worth more than warranty language carving out the outcome.
Sometimes a sound existing floor can be abraded and recoated, and that is genuinely cheaper. More often a coating that failed once did so for a reason recoating does not address, and fresh material over a compromised bond buys about a year. We test adhesion and give a straight recommendation, including when full removal is the only thing worth paying for.
Most commercial floors we coat are in buildings that keep running, so the work is phased rather than simply scheduled. We break a floor into bays or zones, work nights and weekends where that is the only clean window, and stage containment and dust extraction so the rest of the building operates. The sequencing plan is part of the proposal rather than something worked out on the first morning.
Healthcare is the largest floor client in this city rather than logistics, and those floors are specified around cleanability and infection control. Kitchens and dish rooms want a seamless, coved, chemically resistant surface taking hot water and daily sanitizer; sterile processing, imaging and laboratories want that plus resistance to whatever is used in the room. Access and phasing are the harder half.
High-cube distribution floors are large-area work over existing power-troweled slabs, and what they need is rarely decorative. Joint filling so hard-wheeled forklifts stop chipping joint edges, crack repair, a hardener or coating chosen on abrasion and impact resistance, and traffic striping laid out to the racking plan. The specification starts from wheel material and traffic pattern rather than from a catalog.
Some areas of a warehouse are their own specification. A battery-charging room needs acid resistance and containment detailing, while a dock apron takes weather, water and the heaviest point loading in the building. The zone where pallet jacks pivot wears in a pattern nothing else matches. We map those areas separately rather than quoting one product across the whole slab.
A freezer floor cannot take a standard ambient-cure system, and this city has real cold storage in it. The substrate sits below the minimum application temperature, thermal cycling moves the slab against whatever is bonded to it, and the work usually stages around a controlled thaw and a plant shutdown. Urethane cement rather than epoxy is the honest answer in most of those rooms.
Colton has an FSIS-inspected food plant in it, and the language around these floors is routinely wrong. There is no such thing as USDA-approved flooring; 9 CFR 416.2(b)(2) is performance-based, requiring floors of durable, cleanable material maintained in sanitary condition, with no federal product approval list behind it. Practically that means a seamless, coved, thermal-shock-resistant floor with documented cleanability rather than a certificate.
Where a floor takes boiling water, steam cleaning, hot oils or daily wash-down, urethane cement outperforms epoxy by a wide margin, because its thermal expansion behaves much more like the concrete under it. That is what stops a floor delaminating the first time a kettle is dumped on it. In a hot wet room it is the system that lasts.
Line striping and color-coded zones are worth doing properly and are widely misdescribed. OSHA 1910.176(a) requires permanent aisles to be appropriately marked where mechanical handling equipment is used, but specifies no stripe width and no color — the yellow line quoted as a standard comes from convention. We lay striping out to your traffic plan instead.
Here the split between residential and industrial coatings is a legal boundary rather than a marketing one. Rule 1113 defines Floor Coatings and Industrial Maintenance Coatings as mutually exclusive categories, and subsection (c)(6) prohibits applying, or soliciting the application of, Industrial Maintenance coatings for residential use. A workshop on a residentially zoned parcel is a residential property however industrial the wear.
These are three different products with three different jobs. A flake floor broadcasts vinyl chips into a wet body coat for a durable, forgiving, slightly textured surface that hides dust and tire marks, while a metallic pour is a decorative effect built by moving pigment through clear resin. A solid color is plainest and cheapest, and it shows every mark. Most Colton garages end up on flake for good reasons.
Flake density changes a floor more than color does. A full broadcast throws chip to refusal until no resin shows, then scrapes and topcoats, giving an even, heavily textured, seamless-looking surface. A light scatter leaves base color visible between chips and reads speckled rather than solid. The full broadcast costs more in material and labor, and it is the one that hides a repaired slab.
Flake blends are sold under proper names rather than descriptions, and those names carry real weight when you compare quotes. Two contractors quoting a gray flake floor may be quoting different blends at different chip sizes and different broadcast rates. We put the blend name, the chip size and the broadcast rate in pounds per square foot into the written scope, so you are comparing the same floors.
A metallic floor is made by dispersing pigment through a clear resin and then moving it — rolled, brushed or blown — so the pigment separates and settles into a marbled depth. The pattern is therefore directed rather than controlled, and no two pours are identical. We show worked examples and describe the effect honestly, because anyone expecting a repeatable pattern from a metallic pour will be disappointed.
Where a wet floor is normal and the surface has to be safe rather than pretty, quartz broadcast beats vinyl flake. Colored quartz aggregate is larger and harder, builds a thicker system, and gives a measurable texture that a DCOF slip resistance figure can be quoted against. That is why it appears in commercial kitchens, wash-down areas and locker rooms rather than in a decorative garage.
Sheen is a practical decision more than an aesthetic one. High gloss looks best on the day and afterwards shows dust, tire marks and every scratch. Satin gives up some depth and hides a great deal, while matte hides the most and reads flattest. In a garage actually used for storage and vehicles, satin is usually the finish people are happiest with a year later.
Polished concrete is not a coating at all: the slab is ground through progressive grits, densified with a chemical hardener and polished to a chosen gloss level, so the finished floor is the concrete itself. It cannot delaminate, because nothing is bonded on top to let go. It also cannot hide a poor slab, which is why the assessment comes first.
An exterior slab is a different specification from a garage floor, and treating them alike is a common and expensive mistake. Outside there is ultraviolet exposure, thermal cycling, standing water and people walking barefoot. That points at ultraviolet-stable chemistry, usually polyaspartic or polyurea rather than a straight epoxy topcoat, with texture broadcast in for slip resistance.
On an inland slab in full sun, color is a comfort decision as much as a design one, because a dark exterior surface gets genuinely too hot to walk on barefoot. Infrared-reflective pigment reduces how much heat a given color absorbs, which widens what is usable on a pool deck or patio. It matters during installation too, since surface temperature drives pot life rather than air temperature.
Colton Epoxy Flooring provides epoxy flooring throughout the greater Colton area, with the same crews and the same standards on every job.
Good to know
Price is driven by slab condition far more than by square footage. A sound 1980s two-car bay needing a grind, joint fill and a full flake broadcast sits at the low end; a pre-war slab needing coating removal, spall repair and a barrier primer sits well above it. We quote after testing, and the written scope names the prep method, the system, the film build and the cure schedule.
Most residential garages are one or two days of work, but the calendar is set by cure rather than labor. Foot traffic comes first, then light use, then vehicle traffic and hot tires last, and every one of those gates moves with slab temperature. We quote return-to-service against the actual surface temperature and dew point on the day, and give you the vehicle date before we start.
Yes, on every slab, before any product is ordered. We use the ASTM F1869 calcium chloride test for surface emission rate and the ASTM F2170 in-situ relative humidity probe for the slab at depth, with thresholds read from ASTM F710. If readings come back high we either specify a moisture vapor barrier primer sized to the number or tell you the slab should not be coated yet.
Acid softens the surface and leaves residue, so the coating bonds to a weak layer rather than to sound concrete, and it cannot produce a consistent profile on a hard-troweled slab. We prepare mechanically instead, with diamond grinding or shot blasting to a measured ICRI concrete surface profile under continuous dust extraction. It costs more on day one and is the single biggest reason a resinous floor lasts.
Sometimes, and we test rather than assume. If the existing film is sound, well bonded across most of the floor and compatible, it can be abraded and recoated. More often a coating that has already failed did so for a reason recoating does not fix, and fresh material over a compromised bond buys about a year. We check adhesion and tell you honestly which case you are in.
Epoxy is the workhorse body coat: high build, strong adhesion, excellent chemical resistance, and it ambers under ultraviolet light. Polyaspartic cures far faster, stays color stable in sunlight and tolerates a wider temperature range, which is why it is common as a topcoat and on exterior work. Most of our garage systems use both, with epoxy building the film and a polyaspartic or polyurea clear coat over it.
Yes, and the question matters more here than most places. Colton sits inside the South Coast Air Quality Management District, where Rule 1113 sets Floor Coatings at 50 grams per liter of volatile organic compounds and Industrial Maintenance Coatings at 100, treating them as mutually exclusive. Subsection (c)(6) also prohibits applying Industrial Maintenance coatings for residential use, so we confirm your building's category before quoting.
Regularly, and it is most of what commercial work involves here. Hospitals, kitchens, distribution buildings and tenant spaces rarely close, so we break the floor into bays or zones, work nights and weekends where that is the only clean window, and stage containment and dust extraction so the rest of the building keeps running. The phasing plan is part of the written proposal.
Often it is not, and we would rather say so. A freezer substrate sits below the minimum application temperature for an ambient-cure system and cycles thermally against whatever is bonded to it. In hot wash-down rooms the same mismatch shows up as delamination the first time boiling water hits the floor. Urethane cement moves much more like the concrete beneath it, and in those rooms it lasts.
We give you the exclusions in writing alongside the coverage, because most warranties in this trade quietly exclude moisture-related failure — the dominant way these floors fail. That is precisely why we test before purchase and specify a barrier primer where readings call for one. A documented moisture reading and the right primer protect you considerably better than language carving out the likeliest problem.
