What affects 3-car garage epoxy cost

Square footage
Most 3-car garages are 600–720 sq ft — significantly more than a 2-car.
Finish selection
Per-square-foot cost is the same, but total cost is higher due to size.
Concrete condition
Larger floors may have more cracks or joints to address.
Preparation
More square footage means more grinding, repair, and coating material.

Is a 3-car garage worth coating?

A 3-car garage is a large, visible part of your home. Coating it transforms the space from a raw concrete storage area into a finished extension of your home.

Because the square footage is larger, the total investment is higher — but the per-square-foot cost is the same as a smaller garage with the same finish.
