Quartz Epoxy Flooring: Where Double Broadcast Beats Everything Else

Quartz runs $7 to $15 per square foot installed, the priciest of the common systems, and it is the one I point people to for wet commercial floors: locker rooms, kitchens, kennels, restrooms, anywhere slip resistance and chemical resistance outrank looks. It is the toughest and grippiest floor in the catalog. It is also the hardest to keep clean, the tradeoff nobody selling it mentions.

The short version

• Overview: $7 to $15 per square foot. The toughest and most slip-resistant system, built by broadcasting colored quartz into resin in layers.
• My take: This is a commercial floor that occasionally belongs in a house. If the space gets wet and takes a beating, nothing else competes. If it is a dry garage you want to look sharp, you are overpaying for grip you will never use.

What a quartz floor coating is

A quartz floor coating is colored quartz granules bonded into epoxy resin and sealed under a clear topcoat, so the walking surface is graded quartz sand held in place by the resin rather than a smooth film alone. A solid epoxy or a flake floor is a resin surface with pigment or vinyl chips in it. A quartz floor is aggregate first, resin second, and that is why it behaves like a different material underfoot and under a forklift.

The quartz is also what gives the system its chemical resistance. Chemical resistance is a coating’s ability to shrug off spills like grease, mild acids, and cleaning chemicals without softening, staining, or breaking down. Quartz is close to inert and the sealed surface has almost nowhere for a spill to soak in, which is why you find these floors in food plants and labs. It is one of the systems in our rundown of floor coating systems, and the one built for abuse.

How a double broadcast epoxy floor is built

A double broadcast is a build where the installer floods a coat of resin, scatters, or broadcasts, dry quartz granules into it until the surface will not take any more, lets it cure, then does the whole thing a second time, so the floor is built in two full aggregate layers instead of one. That second pass is what separates a real quartz floor from a thin decorative one.

The mil totals tell the story. Reading the Sikafloor Quartzite Broadcast System data sheet (Sika, Edition 12.2020), the build is a primer at 10 mils, a first broadcast coat at 15 mils packed with quartz, a second broadcast coat at 20 mils with more quartz, then clear topcoats at 10 to 20 mils. A mil is a thousandth of an inch. That stacks to roughly 3 mm, about an eighth of an inch of floor. A cheap roll-on garage kit is often 3 to 5 mils total, so a quartz floor is about ten times the build, which is why it costs what it costs and lasts the way it does.

What quartz costs

Quartz runs $7 to $15 per square foot installed, the top of the system range, because you are paying for more material and more labor: two broadcast passes, the aggregate itself, and the grinding underneath that any heavy-duty floor demands. Here is where it sits against the others.

Ranges from the EpoxyTimes rate card, updated September 4, 2026. Those are system ranges, not your specific job. A space carries its own number: a restaurant or commercial kitchen typically runs $8 to $14 per square foot whatever system goes down, which is covered for commercial and home kitchen floors and across what floors cost. Slab condition moves it too: from the rate card, cracks or pitting add roughly 10 to 25 percent, and a rough or previously coated slab that has to be ground back adds 25 to 40 percent. Price your own space in the cost calculator before you take anyone’s word for it.

Where it wins: the anti-slip epoxy floor

Quartz is the anti-slip epoxy floor, full stop, because the grip is built into the surface rather than added on top. Slip resistance is measured by DCOF, and DCOF, or dynamic coefficient of friction, is how much grip a floor gives underfoot while you are moving across it, which is the number the flooring trade uses to rate wet slip resistance under ANSI A326.3. That standard sets 0.42 as the minimum wet DCOF for a level interior floor, and steps the minimum up toward 0.55 for wetter and tougher conditions.

Here is how the systems stack against that bar. A smooth epoxy or polished concrete floor usually falls below 0.42 when wet, which is why smooth epoxy gets slippery when wet and needs an anti-slip additive broadcast into the topcoat to clear the line. Quartz does not need that additive, because the quartz aggregate is the texture. The surface you walk on is graded sand, so it clears the wet threshold and reaches into the higher categories a smooth coating cannot hit without help. On quartz you are not buying grip separately, it comes with the build.

Where that matters:

• Wet commercial floors. Locker rooms, commercial kitchens, kennels, restrooms, washdown areas. These have to stay safe wet and take chemical spills, and quartz does both, and in a food space it still has to be food safe once cured. It also fits how the spaces are regulated: OSHA 1910.22 requires walking-working surfaces to be kept clean and, where feasible, dry, and public floors fall under ADA Standards section 302, which requires ground surfaces to be stable, firm, and slip resistant.
• Residential cases where it fits. A dog run, because it takes claws, hosing, and mess. A mudroom or walk-out basement entry that sees wet boots and grit. These are the spots in a house that behave like commercial floors, and the only places I would spend quartz money at home.

Where quartz loses

The texture that makes quartz safe is the same texture that makes it a pain to clean, and this is the part the product pages skip.

• It holds dirt. A floor with tooth grabs grime, and a mop drags across the high points without lifting what settles between them. Quartz wants a stiff-bristle deck brush or an auto-scrubber, not a string mop. In a busy kitchen that is a real chore, and a smoother floor would wipe clean. You are trading cleanability for grip, on purpose.
• It costs more. It is the priciest system on the board, and if the space does not genuinely need the toughness and the traction, that money is better spent elsewhere.
• It looks industrial. Quartz reads as a uniform speckled work floor. It is not the marbled, decorative look people chase in a home. That is a feature in a lab and a drawback in a kitchen you cook Sunday dinner in.

Quartz versus flake at a glance

The honest comparison for most people is quartz against a flake floor, because flake is the default and quartz is the upgrade you have to justify.

Ranges from the EpoxyTimes rate card. If your decision is really about cure time and UV rather than grip, the full method is in epoxy versus polyaspartic, and the polyaspartic guide covers when a faster topcoat earns its premium.

Quartz is a commercial floor that wandered into the residential catalog. In a kennel or a restaurant kitchen it is the right answer and nothing else is close. In a dry two-car garage it is grip you will never use and a cleaning job you will resent. Buy it for the water and the abuse, not for the look.

How to buy quartz without getting burned

Because quartz is a layered system, a thin or single-broadcast job will look right on day one and thin out at the traffic lines within a couple of years. Put these on the spec sheet and make the bid answer them in writing:

• Two full broadcast passes, broadcast to refusal. Refusal means they keep adding quartz until the wet resin will not absorb any more. One skimpy pass is where corners get cut. Ask for the total system thickness in mils and get the manufacturer’s data sheet for the exact product.
• The grind underneath. A floor this heavy needs a mechanically profiled slab, ground or shot blasted, not acid-etched. No prep, no bond.
• The tested wet DCOF, specified to ANSI A326.3, for the traction the space needs. A crew that cannot give you a number has not thought about you walking on it wet.
• A cleaning plan. If the answer to how you maintain the texture is a mop, they have not run one of these floors.
• Moisture testing on the slab, ASTM F1869 or F2170, because quartz over a wet slab delaminates like anything else.

When you are ready to compare crews, the installer directory lists only companies whose licenses we have verified, and you can have a quote checked before you sign.

Frequently asked questions

What is epoxy quartz flooring? Colored quartz granules broadcast into epoxy resin and sealed under a clear topcoat, built up in two aggregate layers to roughly an eighth of an inch. The quartz is the walking surface, which is what makes it the toughest and most slip-resistant of the epoxy systems.

How much does 1000 sq ft of epoxy cost? It depends on the system. For quartz at $7 to $15 per square foot, 1,000 square feet lands around $7,000 to $15,000 installed before slab condition. A flake floor over the same area runs less, at $5 to $9 per square foot. Run your real number in the cost calculator rather than trusting a flat figure.

What is the downside of epoxy flooring? For quartz specifically, it is cleaning and cost. The texture that makes it slip resistant also traps dirt, so it needs a stiff brush or an auto-scrubber instead of a mop, and it is the priciest system there is. In a dry, low-traffic space you are paying for grip you will not use.

Can you put epoxy on quartz? That usually means an epoxy coat over a quartz countertop, which is a different job from quartz flooring and not what this page covers. On the floor side, the quartz is inside the epoxy build, not a slab you coat over. If you mean recoating an existing quartz floor, yes, a sound floor takes a fresh topcoat once it is cleaned and lightly abraded.
