The fastest useful answer is a range, not a suspiciously precise online quote. Duke City Surface Coatings lists garage coatings starting at $5.50 per square foot and its Signature full-flake system typically at $6.00–$7.50 per square foot. Most standard two-car garages are approximately $2,500–$3,500, subject to site conditions.
What a typical two-car garage may cost
For a simple budgeting example, a 400-square-foot floor at $6.00–$7.50 per square foot suggests $2,400–$3,000 before unusual repairs or other project-specific changes. Actual two-car garages vary in size, and small projects may have minimum charges. That is why our broad planning range for most standard two-car garages is about $2,500–$3,500.
These figures are Duke City planning prices, not a binding bid or a market-wide survey. Your written estimate should state exactly which preparation, repairs, finish, and edges are included.
What moves the price?
Square footage is only the beginning. Slab condition, cracks and spalling, oil contamination, moisture, access, the selected coating chemistry, decorative finish, and the amount of prep can all change the final number. A floor that needs extensive repair cannot be priced accurately from size alone.
- Condition: cracks, pitting, old coatings, and contamination may add prep.
- System: full-flake, quartz, and decorative options use different materials and labor.
- Site: moisture, access, stairs or stem walls, and project size affect the scope.
How to compare quotes fairly
Ask each installer to describe surface preparation, crack treatment, coating layers, flake coverage, topcoat, cure guidance, and written warranty terms. Two bids that look similar on price may include very different work. The American Concrete Institute’s substrate-preparation guidance underscores why the slab assessment belongs in the conversation.
Get a more useful ballpark
Measure the floor’s length and width, note visible damage, and take a few photos in good light. Our estimator can turn that information into a starting range; a final proposal follows a review of the actual project.
Budget roughly $2,500–$3,500 for many standard two-car garages, then confirm the scope and site conditions before treating any number as final.
