Where do you need concrete floor coating?

Professional epoxy floor coating costs $3–$12 per square foot, or $1,500–$6,000 for a standard 2-car garage (400–600 sq ft). Polyurea/polyaspartic coatings (more durable) run $5–$15/sq ft. DIY kits cost $50–$300 but often peel within 1–2 years.

Professional epoxy coatings last 10–20 years with proper preparation. Polyurea and polyaspartic coatings can last 15–25+ years and are more resistant to UV yellowing, hot tire pickup, and chemical spills. DIY retail kits typically last 1–3 years before peeling or wearing through.

Polyaspartic coatings are the current industry standard for residential garages — they cure in 1 day (vs. 3–5 for epoxy), resist UV yellowing, handle hot tire pickup, and are more chemical resistant. Epoxy remains a good mid-range option. Avoid water-based retail kits for long-term results.

Polyaspartic coatings: 1 day from prep to walk-on ready. Epoxy coatings: 2–3 days (1 day prep, 1–2 days coating, plus 24–72 hour cure before parking on it). Professional surface preparation (diamond grinding) takes 2–4 hours and is the most critical step for coating adhesion.
