How many square feet will 1 gallon of epoxy cover?

It’s not uncommon to have to repair a concrete floor, whether it be a garage, shop, or industrial facility. In order to do so, you’ll need to apply an epoxy coating to the floor. The problem is, in many cases, these floors are fairly large. How much epoxy will you need to cover the floor?

This can be a tricky question because it depends on many different factors–the size of your pour and how smooth the surface is being painted. Nonetheless, we can give some general information that will help you determine how much epoxy paint you’ll need for your project.

The answer depends on several factors. First, ask yourself these questions:

  • How much surface area is being covered? One gallon of epoxy will cover about 150 square feet of flat, solid concrete (like a patio or garage floor). It’s important to remember that you’ll need two coats for best results, so the coverage will be reduced by 50 percent. However, if your project involves multiple surfaces that require different treatments—for example, an asphalt driveway with a concrete sidewalk next to it—you can typically expect the same amount of coverage from one gallon as well as two.
  • Is there anything else involved in your project? When applying epoxy over another product like a concrete sealer or paint primer (see our recommendations below), it’s important to use a little math before planning out your mixing schedule. For instance: If you’re using 1-gallon containers and want to apply an oil-based stain between coats of epoxy floor coating on top of previously sealed floors located in an area where rainstorms frequently occur (such as southern California), then plan on using 2 gallons per coat rather than just 1 because these conditions require extra protection against moisture penetration into porous substrates such as concrete blocks; likewise, if those same areas are subjected regularly

to extreme sunlight exposure—as can happen during long summers here in Florida where we live–then again plan accordingly!

The answer to this question depends on the amount of material that you use, but it’s a good place to start. If you apply two gallons of epoxy, it should cover about 200 square feet.

That number is going to vary depending on how thickly or thinly you apply the epoxy, so keep this in mind when considering how much coverage you’re getting out of each gallon.

For example: if your room has a floor area that measures 10 feet by 10 feet and your friend applies an extra-thick coat of epoxy over the entire surface—so thick that it’s one inch deep all over—then yes! That would be enough for 200 square feet worth of coverage.

But if he just paints over every inch with a thin coat (which is more typical), then no! That won’t get him close enough already covered areas at all; he’d need three times as much product because his “square foot” measurement includes not just floor space but also wall surfaces and other vertical areas like closet doors or windowsills too!

How do I calculate how much epoxy I need?

  • Calculate the square footage of the area you want to cover.
  • Multiply your total square footage by 1 gallon per 100 square feet, so for example:
  • If you have a 9 x 12 room, that’s 108 sq. ft., so divide that by 100 and multiply it by 1 (the amount of epoxy you need) = 108 divided by 100 is 0.96 or 96 ounces (or 2 quarts). You’ll need 3 quarts of epoxy for this job because it’s just under 4 times as much area as you can cover with one gallon.

How much epoxy do I need for 20 feet?

How much epoxy do I need for 20 feet

If you were to ask us how much epoxy would be needed for 20 feet, we’d have to say “it depends.” How thick or thin you apply the coating and what type of surface you are applying it on will factor into your final answer.

We recommend starting with a 1-gallon container. This is enough epoxy for about 20 feet of coverage at a thickness of approximately 1/16 inch. The exact amount will vary based on your application method, but most homeowners find this amount sufficient for their projects.

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

You will need two gallons of epoxy to cover your 2 car garage. If you are using a brush, you may need to apply a second coat. If you are using a roller, you may not need to apply another coat.

How thick should epoxy floor be?

The amount of epoxy floor coating you’ll need depends on the size of your room and what level of finish you want. If you want a high-gloss finish, then a thinner layer is needed than if it’s going to be more of a satin or matte finish. The following chart can help determine how much product to purchase:

  • 1/4 inch = 20 square feet
  • ½ inch = 40 square feet
  • ¾ inch = 60 square feet
  • 1 inch = 80 square feet

How many square feet does a 5 gallon of epoxy paint cover?

How many square feet does a 5 gallon of epoxy paint cover

You should expect 5 gallons of epoxy paint to cover up to 50 square feet.

If you use an average roller and apply the product correctly, you can expect this number to be lower—around 40 square feet.

You will likely achieve higher coverage rates with a high-quality brush and a little more time spent on application.

Results here could range from 40-80 square feet depending on your skill level, but 80 is probably the most likely result for someone who knows what they’re doing with a brush in their hand (and isn’t just slapping it around).

Finally, if you have lots of time on your hands and want every drop of material out of that canister before putting it away for another day, then 100+ square feet per five-gallon bucket might be within reach!

How much is epoxy per gallon?

Epoxy is a very expensive material, and there are many different types of epoxy. Epoxy is typically used as a liquid hardened with addition of resin or hardener. It can be spread on surfaces using brushes or rollers, or it can be poured into molds to create objects such as tabletops and jewelry.

Epoxy resin is a thermoset material that begins curing when it’s mixed with its catalyst (hardener). In order to fully cure, epoxies must meet specific temperature requirements during their curing process: they’ll begin setting at room temperature but won’t fully harden until they reach about 70 degrees Fahrenheit (21 degrees Celsius).


Epoxy is a great way to set up surfaces and protect them from wear and tear. It’s also a great way to spruce up the look of your space, especially if you’re going with metallic or shimmering epoxy.

However, when you’re planning how many gallons of epoxy to get for your space, it’s important to keep in mind that one gallon only covers about 3 square feet. So for larger spaces (or if you have multiple projects on the go), make sure you have enough before starting!
