Garage floors, shop floors and patios coated with a system that survives 100-degree Central Valley summers — ground down to bare concrete first, so it actually sticks.

Epoxy flooring is a resin coating bonded directly to your concrete slab. Two parts get mixed on site, spread across the floor, and cure into a hard plastic shell roughly 20 to 40 times thicker than garage paint from a big-box store.
The part nobody sees is the part that matters. A coating is only as good as the concrete under it, so the slab gets diamond-ground open before any resin comes out of the bucket. That grinding leaves a profile the industry calls CSP 1 to 2 — the floor should feel like 100-grit sandpaper and soak up a splash of water in under a minute.
Most of our work is residential garages. We also coat home gyms, laundry rooms, patios, and the shop floors behind businesses along Wilson Way and Waterloo Road.
Four systems, one prep standard. Every floor starts with the slab ground open.

Pigment worked by hand while the resin is wet, so the finished floor has depth and movement.
Metallic epoxy flooring details
High-build coatings, joint repair and anti-slip aggregate, phased so your operation keeps running.

Concrete grinding detailsFive situations send most homeowners looking for a floor coating.
Sheets lifting near the garage door usually mean the last installer acid-etched instead of grinding. Acid does not remove the silicone and tire polymer soaked into the concrete, so the coating never bonded in the first place.
Hot tire pickup leaves circular dull patches where the car parks. It is a product problem, not a prep problem — low-solids kits soften under a tire that just came off Highway 99 in August.
Bare concrete is porous. Once a slab has drunk enough motor oil, degreaser stops working because the stain lives below the surface. A coating seals the pores so the next drip wipes up.
Gym, workshop, second living space — the floor is the first thing that has to change. Dust from bare concrete never stops, and it settles on everything you store out there.
Central Valley clay moves with the seasons. Hairline cracks get filled with a flexible polyurea before coating; anything wider than a pencil gets evaluated before we quote.
A finished garage floor is one of the cheapest ways to make a Brookside or Spanos Park listing photograph better than the one down the street.
A standard two-car garage runs one or two days on site. Here is the actual sequence.
Water dropped on the slab should darken it within a minute. If it beads, the concrete was sealed and needs heavier grinding. On slabs below grade or anything in the older central Stockton neighborhoods, we test for vapor coming up through the concrete — that pressure is what lifts coatings off from underneath.
Walk-behind grinders with vacuum shrouds take off the top layer, including the weak cement paste that machine-troweled slabs leave behind. This is the loud, dusty half of the job and it takes longer than the coating does.
Cracks get chased out and filled, spalled edges get rebuilt, and the patch gets ground flush. Skipping this step means every flaw telegraphs through the finished floor.
The pigmented resin goes down with a squeegee and gets back-rolled. In a garage in July the pot life shortens noticeably above 90 degrees, so we start early and mix smaller batches than we would in winter.
For a flake floor, vinyl chips get thrown into the wet base until the surface is fully covered. The next morning the loose flake gets scraped and vacuumed off.
One or two clear coats seal the flake and carry the wear. This layer decides how the floor handles hot tires and UV.
Walk on it the next day. With a polyaspartic topcoat you can park on it in about 24 hours. With a straight epoxy topcoat, give it closer to a week before the car goes back in, and about a month before the chemistry is fully hardened.
Etching is faster and cheaper and it is why so much of the failed coating in this town looks the way it does. Grinding costs us more hours per job and it is the single biggest reason a floor lasts.
Stockton gets about 18 inches of rain, and almost none of it falls between mid-May and early October. That dry stretch is why summer installs go smoothly here. It is also why UV stability matters on any floor that catches afternoon sun through an open door — standard epoxy ambers over time, so those floors get a UV-stable topcoat instead.
The person who quotes your floor is on the grinder the morning it happens. Nothing gets handed to a subcontractor between the estimate and the topcoat.
Professionally installed epoxy runs about $4 to $10 per square foot here. Roughly $1 to $5 of that is material and $3 to $5 is labor, which is why the prep-heavy jobs land at the top of the range.
| Garage size | Approx. square feet | Typical installed range |
|---|---|---|
| One car | 240–280 | $1,200 – $2,200 |
| Two car | 400–576 | $1,900 – $4,600 |
| Three car | 620–750 | $2,900 – $6,200 |
An empty garage on install day, a slab in decent shape, and a solid color instead of a metallic pour. Clearing the space yourself is the easiest money you will save on the whole job.

We measure the slab, check it for moisture, and give you a written number before we leave. No charge and no obligation.
A properly ground and coated garage floor typically holds up 10 to 20 years under normal residential use. The two things that shorten that are skipped surface prep and a thin topcoat that cannot handle hot tires in a Central Valley summer.
Expect $4 to $10 per square foot installed, which puts a typical two-car garage between roughly $1,900 and $4,600. Concrete repair, stripping an old coating, and metallic finishes all move a quote toward the upper end.
Yes, and summer is actually the easiest season here because Stockton goes essentially rainless from mid-May to early October. The adjustment is timing: above about 90 degrees the resin's working time shortens, so we start early in the day and mix in smaller batches.
Almost always one of two reasons. Either the concrete was acid-etched instead of diamond-ground, which leaves tire polymer and silicone in the slab so the coating never bonded, or moisture vapor moving up through the slab built enough pressure underneath to push the coating off.
Epoxy is the base layer and is the more affordable of the two, but it cures slowly and can yellow with UV exposure. Polyaspartic is dry to walk on in about an hour, holds its color in sunlight, and goes down across a wider temperature range, but it costs more. Most floors we install use epoxy as the base with a polyaspartic clear coat on top.
Yes, the slab needs to be completely clear before grinding starts. Emptying it yourself the night before keeps the crew on the floor instead of on your storage, and it is the simplest way to keep the labor line on your quote down.
