About This Tool
The Epoxy Resin Calculator helps you determine the precise amount of resin and hardener needed for your boat building project. It takes into account the application type, epoxy system, surface area, thickness, and environmental conditions to provide an accurate estimate of your material requirements.

Key Concepts:

Mix Ratio: The specific ratio of resin to hardener required for a proper cure. This varies by epoxy system.
Pot Life: The amount of time you have to work with a mixed batch of epoxy before it begins to gel.
Working Time: The time you have to apply and tool the epoxy before it becomes unworkable.
Waste Factor: An extra amount of epoxy to account for material left in mixing cups, on rollers, and other waste.
