How much epoxy do I need for 400 square feet? This depends on a few factors, such as how thick of an application you need and the surface area of your project.
The good news is that you can use the calculator above to get a reliable estimate of how much resin you’ll need. With this in mind, the average person will require double the amount of resin needed for their project if they want to fully coat it with resin.
So for example, if you want to cover 400 square feet with 1/4″ of epoxy, you should plan to buy two gallons of resin.

How many square feet does a gallon of epoxy cover?
When working on a DIY project, it’s always helpful to have a good estimate of how much material you will need. In this case, we’re talking about the amount of epoxy needed to cover 400 square feet.
The answer: 1 gallon covers 400 square feet.
How many square feet will 2 gallons of epoxy cover?
It depends. The amount of epoxy you’ll need to cover a particular area will depend on the size and shape of your project.
But in general, one gallon should cover around 100 square feet (depending on application methods), and two gallons will cover about 400 square feet.
How do I calculate how much epoxy resin I need?
If you’re wondering how much epoxy you’ll need, the answer is simple. Divide the area to be coated by the square footage of a gallon of epoxy. If you’re working with 5-gallon buckets, divide that number by 5.
You probably don’t want to do all this math yourself, so let’s say you have 400 square feet to coat. That would mean 80 square feet per gallon: 400 / 5 = 80
If you’re working with 5-gallon buckets and want to know how much epoxy resin will fit in them, divide your total square footage by 20 (5 buckets x 4 gallons).
In our example above where we have 400 square feet of concrete to cover: 400 / 20 = 20 gallons per bucket
How much does a 5 gallon of epoxy cover?
You can use 5 gallons of epoxy to cover up to 400 square feet. If you want to know how much epoxy it will take to cover a smaller area, let’s break it down:
- 5 gallons of epoxy will cover 200 square feet
- 5 gallons of epoxy will cover 100 square feet
- 5 gallons of epoxy will cover 50 square feet
- 5 gallons of epoxy will cover 25 square feet
How much epoxy do I need for 800 square feet?
If you are looking to cover 800 square feet, you will need 2.4 gallons of epoxy.
This is equal to 1.2 gallons of resin and 1.2 gallons of hardener. You will also need a stir stick and a stirring rod for the mixing process.
If you purchased our kit with both the 2-part Epoxy Resin and Hardener included, then all you have left to do is mix it up!
How much epoxy should I use?
If you are using an epoxy coating over a concrete or masonry surface, it is important to consider the method of application. This will help determine how much epoxy you need for 400 square feet.
If you are applying the epoxy with a roller, then one gallon of epoxy should cover 200 square feet.
If you are applying the epoxy by hand, then one gallon of epoxy should cover 100 square feet.
If you are spraying your concrete with an airless sprayer and diluting your mixture so that each gallon covers 40-50 square feet (which is more than enough), then one gallon will cover 20 square feet (or two coats).
How much is epoxy per gallon?
How much epoxy you will need for 400 square feet depends on whether you are using a liquid or an epoxy resin. Epoxy resin is sold in gallons, quarts, pints, and cups.
Liquid epoxy is measured in ounces and comes in 1-gallon containers (about 28 oz). If you want to know how much liquid epoxy to buy for 400 square feet, multiply the number of ounces by 28 (the amount in each gallon).
Then divide that number by 1/2 gallon (or half of a quart) because each quart bottle holds approximately 16 oz of liquid epoxy.
How much does 16 oz of resin cover?
To answer this question, we need to know how much a 16 oz bottle of epoxy will cover. The answer is:
- 80 square feet (7.5 feet x 10 feet)
- 3 square yards (9 feet x 9 feet)
- 2.5 square meters (3 meters x 2 meters)
- 2.5 square yards (4 yards x 3 yards
Congratulations! You now know how to figure out how much epoxy you will need for your project. It may seem like a lot of math at first, but once you get the hang of it, it will become second nature to you.
