2-Car Garage Epoxy Kit

A 2-car garage runs about 400 to 500 square feet depending on the builder, and that is the size where guessing gets expensive. One EF-100 kit covers 350 to 400 square feet at a standard garage build, so a 2-car floor takes two 3-gallon base kits. Two kits give you 700 to 800 square feet of coverage, which absorbs the waste cushion and the extra material a freshly ground slab drinks up on the first pass. Measure your own slab before ordering: builder 2-car sizes vary, and 40 square feet can be the difference between comfortable and short.

What a 2-car garage floor needs

• 2 EF-100 base kits, or EF-150 / EF-155 when you need a faster recoat window
• 2 metallic pigment pods: one 160 gram pod tints one 3-gallon kit, so match pods to base kits
• 1 to 2 polyaspartic topcoat kits: one kit of EF-275 or EF-280 covers a smaller 2-car around 400 square feet, two kits for larger floors or a heavier wear course
• Flakes, optional: a 25 pound box handles a light broadcast, step up to the 40 pound box for a full broadcast floor
• Tools: a flat squeegee, an 18 inch roller with spare covers, and spike shoes

Order of work

Grind or etch, vacuum, then pour and spread the base one mixed kit at a time, keeping a wet edge between batches. Back-roll, broadcast flakes into the wet film if you are running flake, and let it cure. Scrape and vacuum the rejected flake, then roll the topcoat in one continuous pass.

Check the math against your slab with the epoxy coverage guide or the contractor material takeoff walkthrough.

Common questions

How much epoxy do I need for a 2-car garage?

Plan on two 3-gallon base kits for 400 to 500 square feet at a standard build, plus a topcoat sized to the same footage. As a thin primer coat at 8 to 10 mils, each kit stretches to 480 to 600 square feet.

Can I do half the floor one weekend and half the next?

You can, but a seam line may show where the pours meet. Most installers split the work a different way: prep day one, coat day two, so each coat goes down in a single continuous pour.
