— Definition

What is Epoxy Quartz?

Epoxy quartz is a double-broadcast aggregate system: 100%-solids epoxy is rolled over a diamond-ground primed substrate, broadcast to refusal with colored quartz aggregate, cured, scraped and vacuumed, then re-coated and broadcast a second time to seal. The floor is finished with a chemical-resistant 100%-solids epoxy or aliphatic urethane top-coat at 2–4 mm total system thickness. Integral cove base is poured to wall, eliminating the floor-to-wall seam where bacteria collect — the spec point that makes the system USDA/FDA compliant for food-contact and healthcare environments. The exposed quartz aggregate self-sets a wet DCOF above 0.70 per ANSI A326.3, the highest practical traction in any seamless resin system.

Our install process.

Documented, photographed and signed off step-by-step. Prep is 70% of lifespan.

  1. 01
    Substrate evaluation
    Existing tile, quarry tile or VCT removed. Slab evaluated for spalls, joints, drains and slope-to-drain.
  2. 02
    Moisture test (ASTM F1869 / F2170)
    Calcium chloride MVER + RH probes at three locations. USDA installs are documented in writing for inspection.
  3. 03
    Diamond grind to ICRI CSP 3
    Aggressive surface profile required for quartz adhesion. Edge-grind to walls and around drains.
  4. 04
    Crack & spall repair
    Polyurea crack fill and polymer-modified mortar at spalls and edges.
  5. 05
    Integral cove base pour
    4–6 inch cove base poured to wall before field broadcast — eliminates the floor-to-wall seam.
  6. 06
    Epoxy primer
    100% solids epoxy primer rolled to seal substrate and key bond.
  7. 07
    First base + quartz broadcast
    Pigmented epoxy base broadcast to refusal with colored quartz aggregate. Cure overnight.
  8. 08
    Scrape, vacuum, second base + broadcast
    Loose quartz scraped and vacuumed; second base coat rolled and re-broadcast for full encapsulation.
  9. 09
    Chemical-resistant topcoat
    Aliphatic urethane or 100% solids epoxy topcoat at full mil for chemical, thermal and UV resistance.
  10. 10
    Inspection & sign-off
    Drains tested, cove base inspected, DCOF spot-checked. Care kit and warranty issued.
— Finish options

Color, texture, depth.

Standard colored quartz palettes from Torginol and ATI — neutrals (slate, sandstone, granite), institutional tones (medical green, dove gray, USDA white) and bold accents (royal blue, hunter, brick). Custom blends available for branded environments.

Epoxy quartz vs. urethane cement.

A practical head-to-head — what each system does well, and where the line is.

Recommended

Epoxy Quartz

  • —Decorative color flexibility
  • —DCOF 0.70+ self-aggregated
  • —Cost-effective for sanitary spec
  • —$9–$14/sq ft
Alternative

Urethane Cement

  • —Thermal-shock resistant (steam, freezer)
  • —Tolerates higher moisture vapor
  • —Limited color palette
  • —$10–$18/sq ft

Verdict: Epoxy quartz wins for general commercial kitchen, healthcare and pharma where decorative options and cost matter. Urethane cement wins where steam cleaning, thermal cycling or higher slab moisture are in play — choose by environment, not preference.

— Frequently asked

Specifics matter.

Is epoxy quartz USDA / FDA approved?
+
Epoxy quartz is the industry-standard sanitary flooring spec for USDA/FDA-regulated environments — commercial kitchens, food processing, dairy, beverage and pharma. The seamless, non-porous surface plus integral cove base eliminates the floor-to-wall seam where bacteria collect. We document installs to inspection standard. The system meets NSF food-contact requirements and is acceptable to local health-department inspectors statewide.
What does epoxy quartz cost per square foot?
+
Installed epoxy quartz runs $9–$14/sq ft in SoCal commercial work. Pricing reflects substrate prep (often including tile demolition), moisture testing, integral cove base (priced linear-foot separately on some quotes), double broadcast quartz, and chemical-resistant topcoat. Larger projects (3,000+ sq ft) drop closer to $9/sq ft due to mobilization economy.
How long does the install take?
+
Epoxy quartz is a 4–5 day install: Day 1 = prep + cove base. Day 2 = first broadcast. Day 3 = scrape, vacuum, second broadcast. Day 4 = topcoat. Day 5 = cure. Walk-on resumes 12–24 hours after topcoat. Forklift and full equipment loading at 5–7 days. We schedule around restaurant or facility downtime windows.
How slip-resistant is the finished floor?
+
Epoxy quartz delivers wet DCOF 0.70+ per ANSI A326.3 — the highest practical traction available in any seamless resin floor. The exposed quartz aggregate stays grippy under grease, water and food residue. We can step the topcoat aggregate up further for ware-wash and beverage line zones where the floor sees standing water continuously.
Can epoxy quartz handle steam cleaning?
+
Yes for routine cleaning and short-cycle steam. For continuous high-temperature steam exposure (above 180 °F continuous, dairy or brewery) we recommend urethane cement instead — its three-part polyurethane mortar tolerates thermal shock that will eventually crack epoxy. We make this call during the on-site spec, not after install.
What's the maintenance cycle?
+
Epoxy quartz cleans with rotary auto-scrubbers and pH-neutral degreaser. The topcoat is recoatable at 7–10 years (or sooner in heavy ware-wash zones), which extends the system to 20+ years without disturbing the quartz layer. Cove base inspections are part of standard health-department audits — easy because the surface is seamless.
