Garage Floor Coating Cost: Epoxy and Polyaspartic

Estimate epoxy and polyaspartic garage floor coating cost — with the free calculator.

A coated garage floor resists oil, chemicals and hot tires — and makes the space easier to clean. Epoxy is the classic choice; polyaspartic is the newer, faster-curing upgrade. Here's what each costs in 2026.

THE SHORT ANSWER

The short answer

Professionally installed epoxy runs $4–$9 per sq ft; flake systems $7–$9 and metallic $10–$18. A typical 400 sq ft garage runs $2,400–$3,600 for epoxy installed. DIY kits cost $1–$3 per sq ft.

01

Epoxy vs polyaspartic

Epoxy is durable, affordable and the default for garages, but yellows in UV and takes days to cure. Polyaspartic resists UV, cures in hours and lasts longer — at roughly $2–$4 more per sq ft.

  • Epoxy installed: $4–$9 per sq ft
  • Flake systems: $7–$9 per sq ft
  • Metallic: $10–$18 per sq ft
  • Polyaspartic: add $2–$4 per sq ft
02

The prep is the secret

Grinding, crack repair and moisture testing are half the job — and where cheap quotes cut corners. A floor coated without proper prep delaminates within a year.
