Introduction
The Epoxy Calculator helps you figure out how much epoxy resin you need for your project. Epoxy resin is a strong liquid that hardens when it dries. People use it to make floors, tables, counters, and art projects. This tool works for both flat surfaces like table tops and round surfaces like coasters or bowls.
To use this calculator, you just need to know the size of your project and how thick you want the epoxy layer to be. You can enter your measurements in inches, feet, or metric units. The calculator will tell you exactly how much epoxy to buy in ounces, gallons, or liters. If you know the price of your epoxy, it will also show you the total cost. This saves you money by helping you buy the right amount - not too much and not too little.
How to use our Epoxy Calculator
Enter your project measurements and cost to find out how much epoxy resin you need and what it will cost.
Width: Type the width of your flat surface in feet, inches, yards, centimeters, or meters.
Length: Type the length of your flat surface using the same unit options as width.
Thickness: Type how thick you want the epoxy coating to be on your surface.
Diameter: For circular surfaces, type the distance across the circle from edge to edge.
Cost: Type the price of epoxy resin per gallon, ounce, liter, or milliliter to calculate total cost.
What is Epoxy Resin?
Epoxy resin is a strong liquid plastic that turns hard when mixed with a hardener. People use epoxy for many projects like making tables, coating floors, and creating art. When you pour epoxy, it starts as a liquid and then becomes solid and clear like glass.
How Epoxy Works in Construction
In construction, epoxy acts like a super glue and protective coating. Workers use it to fill cracks in concrete, protect floors from damage, and make surfaces waterproof. Epoxy bonds to almost any material including wood, metal, and concrete. Once it hardens, it creates a surface that resists water, chemicals, and heavy wear. For concrete projects, you might also need our Concrete Calculator to determine the base material requirements before applying epoxy coatings.
Measuring Epoxy for Your Project
Getting the right amount of epoxy is important. Too little means your project won't be covered properly. Too much wastes money since epoxy can be expensive. You need to know three things: the width and length of your area (or diameter for circles), and how thick you want the epoxy layer to be. Most epoxy projects use layers between 1/8 inch to 2 inches thick.
Types of Epoxy Projects
Common epoxy projects include garage floor coatings, river tables, countertops, and jewelry making. Garage floors usually need a thin coat of about 1/8 inch. River tables and artistic projects often use thicker pours of 1-2 inches. Each project type needs different amounts of epoxy, which affects your cost and planning. If you're working on driveways or parking areas, consider using our Asphalt Calculator for those surfaces instead.
Cost and Coverage
Epoxy resin typically costs between $40 to $150 per gallon. One gallon covers about 12 square feet at 1/8 inch thick. Thicker applications use more epoxy and cost more. Always buy a little extra epoxy for your project since running out mid-pour can ruin the finish.
