Garage Epoxy Flooring in Grand Forks, ND

Bare concrete is porous. It soaks up oil, antifreeze, and road salt brine, and every winter freeze-thaw cycle works tiny cracks a little wider. After a few North Dakota winters, most unsealed garage floors are pitted, stained, and starting to spall at the surface.

Why Grand Forks Garages Need More Than Paint

Standard concrete paint sits on top of the surface without bonding to it. It looks fine for a season, then peels the first time a hot tire or a puddle of snowmelt sits on it. A true epoxy or polyaspartic floor coating chemically bonds to properly prepped concrete, which is the difference between a coating that lasts two winters and one that lasts fifteen. That prep — covered in detail on our concrete grinding and surface prep page — is the single biggest factor in how long your floor lasts.

Our Garage Floor Process

1. Diamond grinding — We mechanically grind the concrete to open the pores and remove old paint, oil stains, and efflorescence.
2. Crack and joint repair — We fill cracks and repair any spalled or pitted areas before coating.
3. Moisture testing — We check moisture vapor levels, especially important for garages built on grade in the Red River Valley.
4. Base coat application — A high-solids epoxy base coat goes down first, bonded directly to the prepped concrete.
5. Flake or color broadcast — Most homeowners choose a full-broadcast flake epoxy floor for texture, hide, and slip resistance.
6. Top coat — A clear polyaspartic or polyurethane top coat seals everything in, adds UV stability, and stands up to vehicle traffic and de-icing chemicals.

What Drives the Price

Garage floor pricing comes down to square footage, the system you choose (solid color, flake, or metallic epoxy), and how much prep your slab needs. Older concrete with cracks, oil staining, or previous coatings takes more grinding and repair than a newer, clean pour. We quote every garage in person, free.
