About EpoxyMath

EpoxyMath is a set of free epoxy resin calculators for woodworkers, resin artists and DIY builders who need to know how much epoxy to mix before starting a project. It covers river tables, deep pours, tabletop and countertop coatings, silicone mold volumes and material costs.

Each calculator returns amounts in ounces, gallons, liters, weight and Part A/B splits, so users can match the numbers to the kit they buy. The site also includes project lookups for common sizes such as coffee tables, bar tops and coasters, along with guides on coverage, waste allowances, cure times and bubble fixes.

What sets it apart is the transparency of the math. The calculators show their formulas and use stated conversions, and everything runs in the browser with no sign-up or tracking. Results are estimates, and the site asks users to follow the manufacturer's instructions and safety data sheet.
