Epoxy vs. polyaspartic: which is right for a Columbus garage?
Both seal and protect your slab, but they behave very differently — especially under hard winters, heavy freeze-thaw, and road salt. Here’s how they compare on the things that matter for a Columbus garage.
Cure, UV, durability, and cost
- Cure time: epoxy takes 12–16+ hours per coat and days to fully harden; polyaspartic cures in about an hour and is usually walk-on the same day.
- UV stability: polyaspartic is UV-stable and won’t yellow; standard epoxy can amber over time in sunlight.
- Durability & lifespan: epoxy typically lasts 5–10 years; a polyaspartic-grade system commonly lasts 15–20+ years and flexes over slab movement instead of cracking.
- Cost: epoxy runs a few dollars less per square foot up front; polyaspartic costs more initially but usually wins on cost-per-year. See typical Columbus ranges on our pricing page.
The Columbus verdict
Central Ohio winters are the deciding factor. Freeze-thaw cycles spall and pit bare concrete, and road salt dragged in on tires etches unsealed slabs all season. A floor here has to be sealed tight against salt and built to ride out months of freezing and thawing without flaking — anything less won’t survive a Columbus winter. A lot of area garages also sit above finished basements, so stopping salt, slush, and moisture at the slab protects far more than the garage floor itself.
For most Columbus garages, a polyaspartic-grade system is the better long-term call — it stands up to hard winters, heavy freeze-thaw, and road salt where a basic epoxy kit gives out. We still spec epoxy where it’s the right fit and budget; the point is matching the system to your slab and how you use it, not selling one answer.
