What sets the price of an epoxy floor.

National guides put a professionally installed epoxy floor at about $7 to $9 per square foot in 2026, which puts a two-car garage of 440 to 550 square feet at roughly $3,100 to $3,900 (ArmorGarage, September 2026). Those are national averages from a company that sells DIY kits, not our prices. Metallic floors, and slabs that need a lot of repair, run higher. The number for your floor comes from the free visit.

The square footage sets the amount of material and time.

Cracks, pits, stains and old coatings all need work before anything goes on top.

Getting the surface ready is labor-heavy, and it's the step that decides how long the floor lasts.

Flake, metallic and solid finishes use different materials, layers and amounts of handwork. Metallic floors take the most.

Every job has the same setup: moving equipment in, preparing the edges, mixing and cleaning up. On a large floor that work is spread over more square feet, so the price per square foot usually comes down as the area goes up. A small room still needs the full process.

Within one system, most colors cost about the same. Custom blends, extra metallic colors or a pattern laid out by hand add material and time, so they can move the number. The finish you choose matters more than the color within it.

Steps, drains, tight rooms and edges take longer than an open rectangle.

A quote should start from the floor as it is: wall to wall, plus steps, landings and any edges that get coated. Rooms that look the same size on a listing can measure differently once closets, alcoves and the area under a workbench are counted. If a quote doesn't say how many square feet it covers, ask.

Most slabs need some repair before they are coated. Cracks are opened up and filled so they don't show through. Pitted or flaking concrete is patched and ground level. Control joints are either filled or kept as joints, depending on the slab. Each repair is a step in the job, which is why two floors the same size can carry different prices.

Paint, sealer or an old epoxy that is still on the floor has to come off before a new coating can bond to the concrete. Grinding off an old coating takes time, and how much depends on how thick it is and how well it is stuck. A floor with nothing on it is the quickest to prepare.

Garages usually need the most preparation for oil, stains and old coatings, and a top coat that stands up to tires. Rooms inside a home often have tile, adhesive or an uneven slab to deal with first. Commercial floors are priced around how the floor is used and when the space can close.

• The area measured, not guessed
• The condition of the concrete, and what prep it needs
• The system and how many layers
• When you can walk on it, and when you can park on it or move furniture back
• What isn't included

Compare the prep, not just the total: a lower price often means less preparation, and preparation is what decides how long a floor lasts. Ask each installer what they checked before pricing. A quote given from a photo hasn't seen the concrete. Why epoxy floors peel →

At the checkout, yes. Many store kits are thinner coatings, and they usually rely on cleaning or etching the concrete rather than grinding it, so the bond is weaker. They can look good at first and lift under tires later. Removing a failed coating before a proper floor goes down adds to the cost of the second job.

• Is moving items out of the space part of the job?
• Is crack and joint repair included, or priced separately?
• Does the coating run up the wall at the edges, or stop at the floor?
• How many coats go down, and what is the top coat?
