Epoxy Garage Floor Cost

How much does it cost to epoxy a garage floor?

A pro epoxy garage floor costs about $4 to $10 per square foot installed, according to HomeGuide. That includes materials at $1 to $5 and labor at $3 to $5 per square foot. Your garage size, slab condition, coating type and local labor rates explain why quotes differ.

HomeGuide's epoxy flooring cost guide gives the $4 to $10 range. Bob Vila lists a typical project range of $1,595 to $3,337, a national average of $2,441 and $3 to $12 per square foot installed. Taskrabbit gives $1,000 to $3,000 for a typical epoxy floor and $3 to $12 per square foot. These are source estimates, not a quote for your slab.

Cost per square foot and by garage size

HomeGuide puts a 2-car garage of 400 to 576 square feet at about $1,600 to $5,800 installed. Its 1-car range is $1,200 to $3,900, and its 3-car range is $2,300 to $8,600. Use your measured floor area rather than the number of cars alone when you ask for quotes.

The quick cost table above uses HomeGuide's floor sizes: 288 to 392 square feet for a 1-car garage, 400 to 576 for a 2-car garage and 576 to 864 for a 3-car garage.

Home Depot's garage floor coating cost guide lists pro-installed polyurea at $2,500 to $3,200 for a 1-car garage, around $4,000 for a 2-car garage and $4,800 to $6,000+ for a 3-car garage. Polyurea is a different coating type and a full-service system. Do not compare those totals as if they were the same epoxy job.

DIY vs professional epoxy cost

DIY can cost less because you do the prep and application yourself. HomeGuide lists raw materials at $50 to $600 and premade kits at $200 to $700. Pro labor alone runs $3 to $5 per square foot. DIY makes sense on a sound, dry slab, not one with moisture or major damage.

For a 450 square foot 2-car floor, $4 to $10 per square foot works out to about $1,800 to $4,500 installed. Bob Vila says labor can be up to 65% of the project price. A kit price does not replace that full installed budget.

Go pro when you have moisture, old coatings or big cracks. HomeGuide says solid, or 100% solids, epoxy should be handled by pros. The cheapest kit is not a saving if the surface beneath it needs work you cannot do well.

Epoxy cost by type

HomeGuide lists water-based epoxy materials at $40 to $100 per gallon, solvent-based at $50 to $100 and solid, or 100% solids, at $70 to $150. One gallon covers about 80 to 200 square feet depending on thickness. Compare coating type and coverage before you use a gallon price to plan your budget.

Flakes or metallic finishes add cost. HomeGuide gives solid epoxy a lifespan of 10 to 20 years, while water-based epoxy may need recoating every 3 to 5 years. These are source estimates, not results from our own testing.

One-part "epoxy" paint, such as BEHR 1-Part Epoxy at about $48 per gallon, is a different, simpler coating. It is not a true two-part epoxy. Our best garage floor epoxy guide compares epoxy, coatings and flooring alternatives.

Prep and repair costs that add up

Prep can change your total even when the coating price stays the same. Bob Vila lists crack and chip patching at $25 to $250 and professional sandblasting at $1 to $5 per square foot. Ask every installer what prep is included, especially if your slab has cracks, oil or moisture.

HomeGuide lists concrete resurfacing at $3 to $7 per square foot and power washing at $0.35 to $0.77 per square foot. Home Depot says deep crack repair or severe moisture fixes may be extra charges on a pro quote. Get those items in writing before you book.

How to save on an epoxy garage floor

Save by comparing the same job across 3 written quotes, not by choosing the lowest headline price. Each quote should list prep, coats and topcoat. HomeGuide says clearing the garage yourself may lower fees. Keep DIY for a sound, dry slab so a cheap coating does not become a costly repair.

Use our garage storage systems guide to plan where things will go while you clear the floor.

• Get 3 written quotes that list prep, coats and topcoat.
• Clear the garage yourself where your installer agrees.
• Fix small cracks before quotes.
• Pick a solid color instead of metallic.
• DIY only on a sound, dry slab.
• Buy enough material for your real square footage plus porosity.

Is an epoxy garage floor worth the cost?

An epoxy floor can be worth the cost when your slab is sound and you plan to keep using the garage for years. It is not worth coating over an active moisture problem. Fix the slab first, then compare the complete system and prep cost rather than judging only the kit price.

Use our best garage floor epoxy guide to compare coatings and alternatives before you buy. If your main use is training, our garage gym flooring guide can help you plan that space instead.
