It’s never fun to deal with a countertop repair. It can be especially frustrating when you find out it’s going to cost thousands of dollars to fix your kitchen or bathroom counter — depending on what type of damage it has sustained.
Thankfully, there are ways to save money on your next project. For instance, if you’re looking to apply epoxy resin over a concrete countertop and want to know how much epoxy glue is needed for this task, we have some answers for you!
How do I calculate how much epoxy I need?
To calculate how much epoxy you need, measure the length, width, and depth of the area to be covered. Multiply these three measurements together to get your total coverage square footage.
Then divide by 144 (the number of square feet in a gallon) to determine how many gallons you need. For example:
- If you want to cover an area that is 3 feet long by 2 feet wide by 1 inch deep (6 square feet), you would multiply those dimensions together (3 x 2 x 1 = 6). You would then divide that result into 144, giving you 10/144 or 0.07714285714286 gallons needed per square foot for this application.
- If instead of calculating out each individual dimension individually and multiplying them together, we just multiply 2 times 3 times 1 (2 x 3 x 1 = 6), we can simplify our calculation even further!

How many square feet will 1 gallon of epoxy cover?
1 gallon of epoxy will cover about 400 square feet, so if you were to use a 2-inch roller with a 5/8-inch nap, it would take two passes over the surface to apply.
If you wanted to cover an 8×12 sheet of plywood, one coat would be sufficient. If you wanted to paint the plywood instead of using a primer first, however, it would probably require two coats.
How much does 2 gallons of epoxy cover?
2 gallons of epoxy will cover 400 square feet. If you’re looking to paint a tabletop that is 200 square feet, you’ll need 2 gallons of epoxy. If your tabletop is 100 square feet, then you should use 1.5 gallons of epoxy.
Lastly, if your tabletop is 60 square feet, then you should use 1 gallon of epoxy.
How much epoxy is needed for a tabletop?
If you want to use epoxy for your tabletop, the good news is that it’s easy to work with. The bad news is that it can be difficult to get the consistency exactly right, so you’ll want to make sure you have enough material on hand before starting.
We recommend using at least 2 inches of epoxy for a standard tabletop, but there are many factors that will affect how much epoxy you need:
- The size of your table
- The thickness of your wood or glass top
- How smooth you want the surface of your table
How much does epoxy cost per gallon?
When it comes to the cost of epoxy, you’ll find that it’s a bit more expensive than polyurethane. The reason for this is that epoxy is a two-part mixture (it needs both the resin and hardener), while polyurethane only requires one component.
Most people will pay between $25 and $50 per gallon for their epoxy. While this might seem like an expensive product, remember that you can get several other uses out of it, so it ends up costing less overall than buying smaller quantities in different applications.
You might even be able to use up all of your leftover material after completing all of your projects!
How thick should epoxy table be?
Epoxy table thickness is a common question for those who want to know what’s the best epoxy table thickness. When it comes to epoxy bathtubs and showers, most people prefer 1/4-inch thickness.
However, there are some that think 1/8 inch is the best option because of its lightweight property compared with 1/4-inch thickness.
How much epoxy do I need for 400 square feet?
To calculate how much epoxy you need, multiply the surface area of your countertops by 4. This will give you the amount of epoxy needed.
For example: If your countertops are 400 square feet, multiply that by 4 to get a total of 1600 square feet.
If your countertops are 100 square feet, multiply that by 4 to get a total of 400 square feet.
Can you cut on epoxy countertops?
You can not cut on your epoxy countertops. Epoxy countertops are made of two parts, the epoxy resin, and the hardener.
The resin is the hard part, and the hardener is the liquid. When you mix them together they become extremely solid and strong, but they also take a while to dry.
The only way to cut on your new epoxy countertop would be if you were willing to wait several hours for it to dry completely before continuing with whatever project you were working on (and we’re sure that isn’t going to be an issue).
After doing a little research, we found that you can use between one and two gallons of epoxy for every square foot of countertop.
This means if you want to cover your entire countertop with just one coat, then you need between two and three gallons of epoxy!
