Garage floor epoxy and Saskatchewan winters
A garage floor here takes salt, slush, and temperature swings. Preparation is what decides whether the coating survives them.
Why preparation decides everything
Coatings bond to the profile of the concrete, not to a smooth sealed surface. Diamond grinding opens the concrete so the coating can key into it. Floors that are simply acid-etched or coated over an existing sealer are the ones that peel in sheets a season or two later.
What winter actually does to a garage floor
Vehicles carry in road salt and moisture that pools and refreezes. Uncoated concrete absorbs that brine, and freeze-thaw cycling causes surface spalling. A properly bonded coating system keeps the moisture out of the slab.
Hot tire pickup
Warm tires can pull poorly bonded coatings straight off the slab. This is a bonding and product-selection problem, not bad luck — another reason grinding and the right topcoat matter.
Caring for a finished floor
Rinse road salt off periodically through winter, wipe spills rather than letting them sit, and use a soft-bristle brush with mild cleaner. Avoid dragging sharp metal edges across the surface.
