Epoxy Calculators
Use Stone Coat epoxy calculators to determine the perfect amount of epoxy needed for your epoxy epoxy countertops, epoxy flooring, epoxy shower, or art resin project.
Surface Calculator (Square Feet)
This calculator estimates material needed for standard epoxy coatings applied at 3 oz per square foot. It is for epoxy coating applications only and should not be used for APEX Polyaspartic coatings, dirty pours, or other techniques requiring additional material.
Square Feet: 0
Gallons Needed: 0
Length × Width ÷ 20 = Gallons
Volume Calculator (Cubic Inches)
This calculator estimates the amount of epoxy needed to fill a specific volume based on your project dimensions. Designed for deep pours, river tables, void fills, molds, and other casting applications—not surface coatings.
