How much does 2 gallons of epoxy cover?

Welcome to the article, How much does 2 gallons of epoxy cover. By reading this article, you can expect to find out how much area a 2-gallon kit of epoxy will likely cover for your project or projects. I’ll also include some valuable tips and info along the way that should help you with your project.

For starters, let’s talk about the structure of this article. Here are a few things I will be discussing:

  • An intro and background on coverage rates for standard 1/8″ thick epoxy floors
  • Also an introduction (and some pointers) to calculating coverage for self-leveling epoxy floors
  • A quick reference chart showing how many square feet can be covered by a kit of standard liquid epoxy floor paint, as well as self-leveling floor epoxy
  • Answers to common questions regarding how much area can be covered by various types of kits and coverage rate calculations

How much does 2 gallons of epoxy cover?

So, how much does 2 gallons of epoxy cover? A gallon of epoxy will cover about 12 square feet at 1/8 inch thick. So to answer the question, 2 gallons of epoxy can cover about 24 square feet at 1/8 inch thick.

The amount of epoxy needed to cover a surface area depends on a few factors:

  • The surface area to be covered
  • The consistency of the mixture (how thin or thick it is)

For example, if you’re pouring an epoxy layer over a tabletop that measures 12 inches by 40 inches and is ½ inch deep, you would need approximately 1.5 gallons of mixed resin and hardener.

That’s because you need enough material to fill ½ inch deep in every square foot of the tabletop (½ x 12 x 40 = 240 cubic inches).

And as we mentioned above, one gallon covers 3 cubic feet at 1/2 inch depth. Therefore, 240 / 216 = 0.5625 which means you will need approximately 0.6 gallons or two 16 oz bottles for the project.

Generally speaking though when people are getting into epoxying for the first time they tend not to buy resin and hardener separately because it can get confusing when trying to figure out how much resin and how much hardener is needed for a project since different brands have different mix ratios (the ratio between resin and hardener).

Instead, most people opt for buying an epoxy kit from their local hardware store since these kits contain everything that you need for your project including mixing sticks and measuring cups so you don’t waste any material by overestimating the amounts needed…or worse underestimating amounts needed!

How many sq ft does a gallon of epoxy cover?

If you’re doing a thin pour of epoxy, such as what’s needed when covering countertops, then you will get 200-300 square feet per gallon.

Thin pours are usually 1/8″ or less in-depth. If you do a thinner coat, you can get up to 400 square feet per gallon. You might be able to go even higher if you take the time to thin out the epoxy.

The deeper the pour, the fewer square feet it will cover per gallon. The rule of thumb is that for every 1/4″ depth of epoxy, it should cover 12 square feet per gallon.

How do I calculate how much epoxy I need?

First, you need to know how thick you plan on applying the epoxy. For example, do you want a thick, half-inch layer or a thin, eighth of an inch layer? The thickness of your epoxy will affect how much material is needed–the thicker the application, the more material it takes to cover the same area.

Next, consider how much square footage you are trying to cover. You can calculate this in feet by measuring one side of your space in feet and then multiplying that by itself.

For example, 10 ft (one side) multiplied by 10 ft (the other side) equals 100 ft2 (total square footage). It’s really important that you don’t forget about any cracks or spaces that won’t get covered with epoxy because these will have to be filled with another product. It is always best to overestimate than underestimate!

The final step is deciding how many coats of material are needed for your project. Most people use at least 3 coats for most jobs; however if used outdoors where there may be exposed to UV light from sunlight, 4 coats (or more!) may be required as this can cause some types of coatings–including epoxy–to break down faster.

Some coatings require primer while others do not; make sure you check with the manufacturer before purchasing their product if unsure whether or not primers are necessary!

The benefit here would mean less time spent sanding after coating applications due to increased bond strength between topcoat layers when using a primer first.”

How much epoxy do I need for 800 square feet?

This is a pretty simple one. You need one gallon per 800 square feet of application area.

If it’s the first time coating, you may need an additional half gallon. This is because the first coat will soak in more than the second coat.

How long should you typically wait between coats of epoxy if you are pouring it very deep?

You should always wait until the first coat is completely set before applying the next coat. If you pour on the second coat of epoxy too soon, it could cause the two coats to fuse together and leave a tacky spot in your piece.

Two gallons will cover 32 square feet at 1/8th inch thick, so if you are pouring it extremely deep you may need more than two gallons. For example, at ¼ inch thick, two gallons will only cover 16 square feet.

As long as you keep this in mind when ordering your epoxy, you should be able to do your project without needing to make a second order!

How much is epoxy per gallon?

When you go to purchase epoxy, the cost will be $45-$60 per gallon. It depends on the brand and type of epoxy that you purchase. This can add up to a lot of money if you are doing a larger project like an entire garage floor or deck.

How much epoxy does it take to cover a table?

To find out how much epoxy you need, first, determine the area of your table’s surface. Then multiply that number by 1-1/2 to get an approximate amount of epoxy needed in gallons.

For example, if your table is 3 feet wide and 5 feet long, the total area will be 15 square feet; therefore, you’ll need at least 1 gallon of epoxy to cover it completely.

A larger table such as one that is 4 feet by 6 feet will require around 2 gallons of epoxy to ensure a thick enough coating in the center.

How much epoxy Do I need to mix for a tumbler?

You will need 2-3 ounces of epoxy to cover a 20oz tumbler.


The amount that 2 gallons of epoxy will cover depends on a few factors. The thickness of the epoxy you decided to use, how much it spreads, and how smooth or rough your floor is are all factors in deciding how far your 2 gallons of epoxy will go.
