Epoxy coating adds a protective layer over concrete for 3 to 12 dollars per sqft. Polished concrete grinds and polishes the existing slab for 3 to 8 dollars per sqft. Epoxy offers more color options and chemical resistance. Polished concrete offers a more natural, industrial aesthetic.
Applies a resinous layer (2-20 mil thick) over concrete. Pros: unlimited color options, chemical resistant, can cover imperfections, anti-slip options, decorative flake and metallic available. Cons: can peel if not properly prepped, yellows in UV (standard epoxy), needs recoating every 10-15 years. Cost: $3-$12/sqft. Best for: garages, commercial kitchens, showrooms.
Grinds the existing concrete surface with progressively finer diamond tooling to create a smooth, glossy finish. Pros: exposes natural concrete character (aggregate pattern), extremely durable (lifetime), no peeling (it IS the concrete), very low maintenance, sustainable (no added materials). Cons: limited color (concrete color + optional dye), can't hide major cracks or damage. Cost: $3-$8/sqft.
Epoxy: 15-20 years before recoating. Vulnerable to: heavy impact (can chip), UV exposure (yellows), and chemical spills (depending on formulation). Polished concrete: lifetime (the floor IS concrete — it can't delaminate). Vulnerable to: acid etching (spills need quick cleanup), cracking (if slab moves), and staining (without sealer). Both are far more durable than tile, hardwood, or carpet.
Epoxy: sweep + damp mop. Recoat topcoat every 5-10 years. Polished concrete: sweep + damp mop. Re-polish high-traffic areas every 5-10 years. Apply penetrating sealer annually. Both are extremely low-maintenance compared to other flooring. Polished concrete has a slight edge in long-term maintenance cost.
Choose epoxy if: you want color options, need chemical resistance, want to hide imperfections, or want decorative effects (metallic, flake). Choose polished concrete if: you want an industrial/modern aesthetic, prefer a natural material, want the most sustainable option, or have a beautiful concrete slab worth exposing. Both are excellent choices for LA's modern design aesthetic.
