How many square feet will 2 gallons of epoxy cover?

When you have a project in mind, it’s important to have realistic expectations of what can be achieved. If you try to build a cathedral out of sandcastles, the results are going to be disastrous. With that in mind, let’s hone your expectations for how many square feet your two gallons of epoxy will cover.

How much does 2 gallons of epoxy cover?

For the most part, it’s hard to tell how much you’ll need until you actually do a project and see how the epoxy works.

However, EpoxyMaster Epoxy, which is a standard industrial-quality epoxy for coating concrete floors and other surfaces, will give about 75 square feet of coverage at 1/8 inch thick. When you double that thickness to 1/4 inch, the coverage rate goes up to 50 square feet.

Knowing this will help you figure out how much material you need for your project. And if you’re hiring someone to do the job for you, this information could also help ensure that they’re not overcharging or using substandard materials.

How many sq ft does a gallon of epoxy cover?

It’s important to keep in mind that the thicker the pour, the more epoxy you will need. How much 1 gallon of epoxy will cover depends on how thick it is poured, but as a general rule for our products, 1 gallon of Pro Marine Supplies table top epoxy will cover up to 13 square feet if poured at 1/8″ thickness.

This equates to approximately 12 sq ft per coat. So if you are pouring your epoxy at a thickness greater than 1/8″ inch and are interested in knowing how many coats you’ll need, simply divide the total number of square feet by 12. For example:

80 sq ft / 12 sq ft per coat = 6 coats

How many square feet will 3 gallons of epoxy cover?

The amount of square footage 3 gallons of epoxy will cover is approximately 450.

How do I calculate how much epoxy I need?

You’ll need to calculate the volume of the space you want to fill and the amount of epoxy needed.

  • Volume in cubic inches = Length (in inches) x Width (in inches) x Thickness (in inches).
  • Epoxy needed in cubic inches = Volume in cubic inches ÷ Coverage, where coverage equals 1/4″ thickness for every 8 oz. of liquid epoxy.

To convert the total volume needed to gallons, divide by 231 (1 gallon is 231 cubic inches).

How much epoxy do I need for 400 square feet?

How much epoxy do you need? This can be a tricky question to answer, and it depends on a lot of different factors. To give an example, let’s look at the most commonly asked question: how much epoxy do I need for 400 square feet?

Now that you know how many gallons of epoxy you need, what’s next? Most people use liquid epoxy in two coats (with sanding in between). How long should you wait between coats of epoxy if you are going very deep into the concrete? The answer is important because if it’s too wet or too dry, your final product will not turn out as well.

It all depends on the brand of concrete and other factors like humidity. The manufacturer of your liquid epoxy probably has some recommendations for this number. Let’s assume the recommendation is 12 hours; we’ll go with that number for now.

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

The exact amount of time you should wait between coats depends on a few factors:

  • The type of epoxy you’re using
  • The thickness of the pour
  • How deep your project is. The deeper it is, the longer you’ll need to wait between pours because the epoxy will take longer to cure.

For most epoxies, it’s recommended that you wait at least 12-24 hours before applying another coat. If you want to create a deep pour and create multiple layers, however, you’ll need to give it more time than that—you should usually wait at least 48 hours between layers. Sometimes the label may specify how long you should wait for a given product; if so, follow these instructions instead of this general advice.

How much is epoxy per gallon?

So, for example, if you purchased three gallons of epoxy, you’d have a total of 36 square feet. With this in mind, you can calculate the amount of epoxy you need by dividing your project’s area by 12 (the number of square feet one gallon covers).

For instance, let’s say we want to cover an area that measures 72 square feet. Divide 72 by 12 and we get 6—so we should buy six gallons. (Tip: You should always round up to the nearest whole number when purchasing anything to cover an area—in this case, six gallons instead of 5.67.)

How much epoxy Do I need to make a river table?

The first question to answer is how much resin you’ll use in your project, and for this, you need to know the size of your surface area. Then you can apply the volume formula:

Area = length x width

Volume = Area x depth

If you have a small end table that is 24” long by 12” wide, then one half-gallon kit (that coats 10 square feet) will be sufficient. But if you decide to make a very large river table that’s 7 feet long and 2 feet wide, then at least two gallons will be needed per side (and possibly more depending on how thickly you want it poured).

And remember—you may need additional epoxy if your project is not perfectly flat or if it contains holes or voids. When in doubt, go with a little extra just in case.


To recap: epoxy is a great material to use when coating a surface, and it comes in many different forms and variations.

With the proper tools and knowledge, you can make almost any surface look brand new. It is important to calculate how much epoxy you will need by measuring the square footage of your project area before buying.

One gallon of epoxy will cover 250-300 square feet, so two gallons will cover roughly 500-600 square feet.
