Why does high-build epoxy cost more than polished concrete?

Because it is a built system rather than a densified surface. A high-build epoxy installation adds an epoxy primer, a clear base coat with silica sand, a second sanded coat and a pigmented chemical and UV resistant topcoat to reach 20-35 mils. That build is what carries the $10-$15 per sq ft range against $5-$7 per sq ft for polished concrete.

Which system resists chemical spills better?

High-build epoxy, rated high and impermeable against low and porous for polished concrete. However, even epoxy has limits: methylene chloride, sulfuric acid at 50%, glacial acetic acid and aniline fall outside its resistance profile, while acetone at 10% must be cleaned within 72 hours.

What prep and moisture testing is required before either system?

Both require mechanical shot blasting to a CSP 3-4 profile plus ASTM moisture testing. For epoxy the substrate must also be 2500 psi and cured for 28 days. Skipping the moisture test is the most common cause of vapour pressure bubbling and delamination.
