How to use the Epoxy Calculator:
Our epoxy calculator is easy to use! Simply enter your product dimensions, including your epoxy depth, and we’ll let you know how much Liquid Glass® Deep Pour Epoxy Resin or Superclear® Table Top Epoxy Resin you’ll need to get the job done.
FAQ’s:
What are the actual formulas used?
The formulas used to calculate the epoxy volume needed, depends on the type of project you are working on.
For most applications (rectangular) you will follow these steps:
- Measure the substrate (or piece) you will be using. Find the length and width in inches, and determine the depth that you would like to pour the epoxy (.25”, 1”, etc.)
- Next multiply the 3 dimensions (L x W x H) together to calculate the volume of the top of your substrate in cubic inches.
- Finally, convert the cubic inch volume to U.S. fluid ounces. To do this you will divide your cubic inches by 1.805. (Cubic Inches / 1.805 = Fluid Ounces)
- Bonus Tip: To convert ounces to gallons, you can divide by 128! (Fluid Ounces / 128 = Gallons)
For round or circular applications you will follow these steps:
- First, measure the diameter of your substrate, and divide by 2 to get your radius. (Diameter / 2 = Radius)
- In order to get your volume in cubic inches you will follow this formula: (radius squared) x pi (3.14159265) x (preferred depth of pour)
- Finally, divide that number by 1.805 to convert the cubic inches to U.S. fluid ounces. (Cubic Inches / 1.805 = Fluid Ounces)
- Bonus Tip: To convert ounces to gallons, you can divide by 128. (Fluid Ounces / 128 = Gallons)
How accurate is the epoxy calculator?
The calculator provides an estimate of the volume required for your application. With this in mind it is important to understand that there are many variables that can cause these calculations to differ from the actual volume needed.
Such as:
- Porous wood that requires multiple seal coats of Superclear® Table Top Epoxy.
- The edges of your substrate are not included in the estimated volume, and as such would need to be accounted for in your calculations, if performing a flood coat or even consider what’s left in the container after mixing. A good estimate is to add around 4-8% extra to account for what may be wasted on the stir sticks or mixing cups.
We recommend purchasing a bit more than what you may need, just to be on the safe side. It is always better to have some epoxy left-over after you finish pouring, than to run short and be forced to continue your project later/start over.
How do you calculate the mix ratio by weight?
We design our epoxy systems with a simple ratio for easy mixing and measuring. While our various epoxy systems may have a 1:1 or 2:1 ratio of Base Resin to Curing Agent by volume, the weight ratio is VERY different. Measuring in a 1:1 or 2:1 ratio by weight will often times resulting in sticky, uncured epoxy in your project. For this reason, you must use a different formula to calculate the mix ratio by weight.
The formula used to calculate the mix ratio of Base Resin (A Side) to Curing Agent (B Side) side by weight will depend on the epoxy you are using. Use the following ratios to determine the liquid volume needed:
- Liquid Glass® Deep Pour Epoxy: 100 parts Base Resin to 44 parts Curing Agent (100A : 44B).
- Deep Pour 24 Epoxy: 100 parts Base Resin to 43 parts Curing Agent (100A : 43 B).
- Superclear® Table Top Epoxy: 100 parts Base Resin to 83 parts Curing Agent (100A : 83B).
To calculate the liquid volume needed of each side for your mix, you will follow these steps:
- First, determine the total amount of epoxy needed.
- Next, take the total weight of epoxy needed and divide by the ratio percentage to calculate the weight of Base Resin need: (Total Weight / Ratio Percentage = A Side)
- Finally, subtract your A side weight from the total weight needed for the project to calculate your amount of Curing Agent: (Total Weight – A Side = B Side).
Examples:
Whether you are using grams, kilograms, tons, or fluid ounces, the weight formula will stay the same. See the examples below for specific calculations with each of the epoxy systems.
- Liquid Glass® Deep Pour Epoxy
100 grams of epoxy needed
100 grams / 144% = 69.44 grams of A Side
100 grams – 69.44 grams = 30.56 grams of B Side - Deep Pour 24 Epoxy
100 grams of epoxy needed
100 grams / 143% = 69.93 grams of A Side
100 grams – 69.93 grams = 30.07 grams of B Side - Superclear® Table Top Epoxy
100 grams of epoxy needed
100 grams / 183% = 54.64 grams of A Side
100 grams – 54.64 grams = 45.36 grams of B Side
Especially in smaller mix volumes, it is incredibly important to keep the ratios exact. Calculating your mix by volume can help to avoid a lot of math and limit the room for error. Remember that some epoxy may be lost in the calculating stage, so it is a good idea to account for more epoxy than you need for your project. It is always better to have left of epoxy rather than not enough.
