Epoxy Calculator FAQs
Which resin should I choose?
Choose Crystal Clear Epoxy Resin for jewelry, coasters, molds, floral keepsakes, and layered casting projects up to 1 inch per layer. Choose Deep Pour Epoxy Resin for river tables, flower preservation, deep molds, and 2–4 inch pours. Choose Coating Resin for glossy 1/8–1/4 inch surface coats on tables, counters, tumblers, and artwork.
Why does the estimate include extra resin?
The default estimate includes a 10% safety allowance to help cover resin left in mixing cups, small measurement differences, and normal project loss. It is better to have a little extra than to run short during a pour.
How do flowers, wood, or embedded objects affect the estimate?
Embedded objects take up space that would otherwise be filled with resin, so your actual resin use may be lower than the full-volume estimate. Irregular shapes can be difficult to measure, so review the result carefully before ordering.
Can I enter measurements in centimeters?
Yes. Choose Centimeters near the top of the calculator. If you switch units after entering measurements, the calculator converts the values for you without clearing your work.
What does oz mean in the calculator?
In this calculator, oz means the mixed liquid volume of the resin kit, not its weight. For reference, 128 oz equals 1 gallon, and about 33.81 oz equals 1 liter.
Why is the recommended kit amount rounded up?
Resin kits come in fixed sizes. The calculator recommends the smallest available combination that covers your full estimate, so the recommendation never intentionally leaves your project short.
Is the calculator result exact?
The result is an estimate for planning and shopping. Recheck every measurement and follow the product instructions for mixing ratio, working temperature, and maximum depth per layer or pour before you begin.
