Epoxy costs less, builds well, and resists a wide chemical range, but tolerates only about 120°F of thermal shock and cures slowly. Urethane cement costs roughly double, handles -40°F to 250°F and steam wash-down, returns to service in 24 hours self-leveling, and is sold on a 15-to-25-year life. Wet processing with hot wash-down is the dividing line.
- Installed cost per sq ft
- $3–$9 (Ace Avant 2026); $6–$10 in food settings (Terrapin)
- $7–$13 standard, $12–$18 thermal shock (Ace Avant); $4–$17 by size (Craftsman)
- Thermal shock tolerance

- -40°F to 250°F, 150°F+ differentials (Craftsman)
- Return to service
- 48–72 hrs foot traffic (Terrapin)
- 24 hrs self-leveling; 48–72 trowel; 8–12 hrs rapid-set (Craftsman, Terrapin)

Polishing turns a sound slab into the wear surface: no cure, lowest ongoing cost, resealing every 3 to 5 years, but no chemical resistance and full exposure of the slab's flaws. A coating adds a chemical-resistant, seamless, colored surface at higher cost with a cure window and a recoat cycle, and hides repairs.
- Installed cost per sq ft
- $3–$8 commercial (Stelr 2026); $5–$12 example (Angi)
- $3–$9 epoxy (Ace Avant 2026)
- Downtime
- None; grinding-pass speed only
- 48–72 hrs to foot traffic (Terrapin); longer to chemical exposure
- Ongoing cost
- Reseal every 3–5 yrs at $0.85–$1.60 per sq ft (This Old House)
- Topcoat recoat at roughly 8–10 yrs in traffic lanes

Both depend on a grounded conductive layer and are accepted to the same ANSI/ESD S20.20 tests. Coatings are seamless and chemical-resistant with resin cure times; tile and sheet are replaceable by the piece, walkable when the adhesive sets, and common in assembly areas with changing layouts.
- Installed cost per sq ft
- $3.34–$13.55 by size (Craftsman 2025)
- Material-driven; varies by product
- Seams
- Seamless
- Tile seams; welded sheet is seamless
- Return to service
- Resin cure, typically 24–72 hrs
- When adhesive sets, often same day

Both produce a coved, cleanable floor for care settings. Welded sheet installs fast with low-odor adhesive, cushions and quiets, and turns a patient room overnight. Seamless resin is harder, handles drains and wash-down, and needs a cure with more odor, which suits sterile processing and labs more than an occupied ward.
- Installed cost
- Product-driven plus seam and cove linear feet
- $3–$8 epoxy, $8–$15 urethane cement (Jinyu) plus $2–$4 per linear ft cove
- Seams
- Heat-welded; flash cove eliminates wall seam
- None; integral cove
- Turnaround in occupied areas
- Overnight per room with low-odor adhesive
- 24–72 hrs cure; odor isolation required

MMA cures in about an hour and installs in cold rooms, which makes it the overnight-turnaround and cooler floor, at $8 to $12 per square foot and with a strong cure odor. Urethane cement is the thermal-shock and wash-down floor at $7 to $18, returning to service in 24 hours self-leveling.
- Installed cost per sq ft
- $8–$12 (Terrapin 2026)
- $7–$13 standard, $12–$18 thermal shock (Ace Avant 2026)
- Cure
- About 1 hour
- 24 hrs self-leveling; 8–12 hrs rapid-set foot traffic
- Cold application
- Yes, including coolers
- Limited; heated enclosure in cold
