Our team provides moisture-mitigating epoxy primers under every pour, delivering a deep, glassy floor for homes and a durable decorative surface for both residential and commercial projects. Backed by 12 years in business and our 2-year workmanship warranty, we've completed over 1,187 projects, from a single lower-level game room to four-car showcase garages.
From grinding the slab dead flat and stitching old cracks to pulling the veins by hand while the resin still flows, our team handles every detail. Serving Riverside and neighboring Villa Park, Diamond Bar and Yorba Linda, we bring sample boards to your house so you judge each color under your own lights before anything is mixed.
Call us today for a free estimate, and we will pour a sample board in the colors you are weighing.

Robert's four-car showcase garage on an estate lot off Santiago Boulevard in Villa Park is a charcoal and silver metallic floor under a scratch-resistant polyaspartic clear. He collects cars and wanted the 4-car showcase garage, about 760 sq ft, to read like a gallery, so we ground the slab flat, primed it and worked the metallic coat by hand, with anti-slip grit in the clear only at the door. Robert's project was an estimated $8,500 to $11,800 and took an estimated 3 to 4 days on site, including a full day for the clear to harden before the cars rolled back in.
Kevin's lower level in The Country Estates in Diamond Bar sat on an old slab with a long settlement crack. We stitched and filled the crack before grinding, then poured designer metallic epoxy in pearl and bronze, high-gloss clear, so the floor shows one continuous swirl with no line across it. The game room and wine room, about 640 sq ft, came in at an estimated $6,800 to $10,400, and the install typically ran a few days longer than a garage because furniture had to move room by room.
A metallic floor is built in four coats over roughly 3 to 4 days, and the look is made by hand in the third coat while the resin is still wet. That is why no two metallic floors match, even in the same color.
Color choice decides whether a metallic floor looks like marble, lava, water or brushed metal, and the movement you pick matters as much as the pigment. Charcoal and silver reads as polished stone, like Robert's garage in Villa Park, while pearl and bronze reads warmer, like Kevin's lower level in Diamond Bar.
Lighting changes how the floor reads. LED shop lights flatten the depth, while warm can lights and daylight from a side door make the swirls look a foot deep.
Metallic epoxy is an interior and covered-space floor, and it fails in direct sun and outdoors. Plain epoxy ambers under UV, and even under a UV-stable clear, a pour that sits in afternoon sun on a Riverside patio heats, moves and dulls.
It works in show garages, game rooms, home offices, studios and wine rooms, and it suits the older lower-level slabs of North Tustin and San Antonio Heights once they pass a moisture test. It is a poor choice for a pool deck, a patio or a garage floor that floods. For wet rooms we steer owners to a textured quartz floor, and for outdoor slabs to a patio, porch or pool deck coating in UV-stable polyaspartic with a grit texture.
The other common mistake is skipping the grind on an older slab. Metallic resin flows to the low spots, so a slab with a dip by the drain shows a dark pool there forever.
Metallic is the showpiece finish, flake is the everyday garage finish and quartz is the hard-wearing wet-room finish. The table compares the three by estimated price, look and grip.
| Floor system | Est. investment | Look | Grip when wet |
|---|---|---|---|
| Designer metallic epoxy floor | Est. $4,500 to $12,000 per floor | Seamless poured stone, high gloss | Slick unless grit is added |
| Two-car garage floor, full flake polyaspartic | Est. $2,800 to $6,200 per garage | Speckled, hides dust | Good with grit in the clear |
| Quartz broadcast floor | Est. $2,000 to $5,400 per floor | Textured, sandy color | Best of the three |
A metallic epoxy floor in the Riverside area is estimated at $4,500 to $12,000 for 400 to 800 sq ft, and the slab repair, the room size and the number of colors move the price most. The two floors above, an estimated $8,500 to $11,800 in Villa Park and an estimated $6,800 to $10,400 in Diamond Bar, sit in the upper half because both started on slabs that needed work.

Investment and duration figures are estimates. Your written quote sets the final price and schedule.
| Job | Est. investment | Est. duration on site |
|---|---|---|
| Designer metallic epoxy floor (400 to 800 sq ft) | Est. $4,500 to $12,000 per floor | Est. 3 to 4 days |
| Interior slab floor with moisture barrier (600 to 1,000 sq ft) | Est. $3,800 to $8,000 per floor | Est. 2 to 3 days |
| Old coating removal by diamond grinding, as prep | Est. $800 to $3,000 per floor | Est. 4 to 8 hours |
An old DIY coating has to come off first, which typically adds an estimated $800 to $3,000 inside the floor job. Walk-on time on the polyaspartic clear is typically 4 to 8 hours, and furniture or cars go back after roughly 24 to 36 hours.
Every price on this page is an estimate and is subject to change. Your written quote after we test and measure the slab sets the final price and the install schedule, and it depends on the slab repair, the square footage and the colors you choose.
Our owner reads every moisture test himself and walks each slab before a metallic system is chosen anywhere inside our 45-mile radius, and the crew that grinds your floor is the crew that pours it. After 1,187 projects in 12 years, we know which slabs will show a dip under metallic and which need a primer first. You get our 2-year workmanship warranty against peeling, delamination and hot-tire pickup, plus coating makers' product warranties, typically 5 to 10 years on professionally installed systems, passed through to you in writing.
Owners often compare metallic with a textured quartz broadcast floor for laundry and mud rooms, or a UV-stable polyaspartic garage system when the car parks in the sun.
We pour metallic floors all around Riverside, with showcase garages in Villa Park estates, lower levels in Diamond Bar's Country Estates and game rooms in Yorba Linda, plus Eastvale, Norco and Claremont on our service area page.
In Woodcrest and El Sobrante homes, a metallic floor is often one room of a bigger plan, such as an interior slab coating for the living areas or a full garage makeover package with cabinets after the floor cures.
A metallic floor is estimated at $4,500 to $12,000 for 400 to 800 sq ft, and your written quote sets the final price after the slab test.
Most installs take an estimated 3 to 4 days on site, with walk-on time typically 4 to 8 hours after the clear coat.
Smooth metallic is slick when wet, so near doors and wet spots we finish at 0.60 to 0.85 DCOF with aluminum oxide or polymer grit in the clear coat, and the gloss stays everywhere else.
No, metallic is for interior and covered rooms, and we recommend a UV-stable polyaspartic deck coating outdoors.
It will match the colors and the style of movement, but every pour is worked by hand, so the exact swirls are yours alone.
Yes, we stitch and fill the crack and grind it flush first, as we did in Kevin's game room in Diamond Bar.
California caps a home improvement deposit at $1,000 or 10% of the contract, whichever is less, and progress payments follow the work.

Start to finish
We walk the slab with you, map cracks, joints and old coatings, and take moisture readings before a system is named.
The system, every coat and its thickness, the colors and the cure and return-to-service times arrive in writing.
The slab is diamond ground with dust control, cracks and joints are filled, and each coat goes down inside its recoat window.
We walk the cured floor with you, go over the care notes and tell you when cars or equipment can come back.
