Oil, grease, rust, salt, and old coating discoloration build up on concrete over time, and pressure washing or store-bought cleaners often only lighten the surface without fully removing what’s soaked into the pores of the concrete.
At Great Garage Floors, we address stains at the source — grinding away the affected surface layer and sealing the concrete with a coating system that resists future stains, rather than masking existing ones.

Road salt, sand, and de-icing chemicals tracked in during Minnesota winters are common causes of staining and surface discoloration that plain concrete can’t resist. Combined with oil drips and everyday wear, unsealed floors stain faster here than in milder climates.
Our coating system is built specifically to resist the salt and moisture Minnesota garages deal with every winter.
About UsSome contractors coat directly over stained concrete, which can lead to adhesion issues and stains bleeding through over time. We grind away the affected layer first, then apply our full epoxy and polyaspartic system for a clean, lasting result.

Yes. In most cases, grinding away the top layer of stained concrete and recoating is enough to fully restore the surface.
Surface cleaning can lighten some stains but usually can’t remove what has soaked into the concrete. Grinding and recoating provides a permanent fix.
A polyaspartic topcoat seals the surface, making it far more resistant to oil, salt, and chemical stains going forward.
