Look
Metallic epoxy swirls like liquid marble. Polished concrete has a natural, mineral look.
Durability
Polished concrete has no film to peel. Epoxy is a coating that can scratch or lift.
Moisture
Polished concrete breathes. Epoxy can blister if moisture is high.
Choosing
Feature areas may suit metallic. Large working floors often suit polishing.
Different systems
Metallic epoxy is a poured coating with swirling pigments. Polished concrete is the slab itself. Each has strong points and trade-offs.
Wear and repair
Coatings can chip and need recoating, while polished concrete is refreshed with abrasives. Spot repairs on either one need care to blend.
Decision shortcut
If you want dramatic swirls and color, metallic epoxy may suit you. If you prefer a natural look that is part of the slab and easy to maintain, polishing is a strong choice.
