A garage coating usually runs $4 to $8 per square foot, and a two-car garage is often about $2,000 to $4,500. Polyaspartic usually runs $6 to $10 per square foot, basements $4 to $9, and decorative finishes $6 to $12. The slab and its prep move the price the most.
Many garages take one or two days. A fast-curing polyaspartic system can sometimes be done in one. Walk-on and drive-on times depend on the product and the temperature, so go by the product sheet.
Diamond grinding to open the concrete, filling cracks and pits, removing old paint or sealer, and a moisture test. Each of those helps the coating grip. When one gets skipped, peeling is the usual result.
A calcium chloride test or an in-slab humidity probe gives real numbers. A square of plastic taped down overnight can hint at damp, but it gives no real number. Compare the results to the limit on the product data sheet.
It can be, with care. Many coatings and primers give off fumes that can catch fire. Turn off pilot lights and burners in the space when solvent-based products are used, keep fresh air moving, and keep people and pets out until the floor has cured.
Only if the slab and air stay inside the temperature range on the product sheet through the whole job and the cure. In an unheated garage that often means waiting for warmer weather. Do not use a portable heater to force it.
A coating bonded to ground concrete seals the surface, so salty meltwater sits on top instead of soaking in. Rinse dried salt off now and then with water and a mild cleaner.
Yes. Flake systems come in many color blends, and metallic epoxy gives a marbled look that suits finished basements and showrooms. Both use the same prep as any coating, with a clear topcoat on top.
Smooth coatings can be. A flake broadcast or anti-slip grit in the topcoat adds grip, which helps in a garage where snow and water get tracked in.
Yes. Shops, warehouses, breweries and showrooms can get an epoxy or polyaspartic system matched to their traffic and chemicals. Commercial floors are quoted per project after a walk-through.
Ask for a certificate of insurance. Ask which product they will use, how they will test for moisture, and what prep is in the price. Then read the product data sheet for cure times.
