Cost of Garage Floor Coating in New Hampshire

Garage floor coating typically costs $4–$10 per square foot installed, or $1,500–$6,900 for a standard 2-car garage (400–500 sqft). Polyaspartic systems run $6–$12/sqft but offer faster cure times and better UV stability. Basic DIY kits cost $50–$200 but rarely match professional results in adhesion or longevity.

• Garage size — 1-car ($800–$2,500), 2-car ($1,500–$4,500), 3-car ($2,500–$6,900)
• System type — flake, solid color, or metallic each have different price points
• Concrete condition — oil stains, cracks, and previous coatings increase prep cost
• Coating thickness — single coat vs. full 3-layer system (primer + base + topcoat)
