Questions people ask before buying epoxy
How accurate is this epoxy calculator?
It is designed for planning and procurement, not for replacing the manufacturer data sheet. The calculator is most useful when you add the right waste buffer and choose the page that matches your project type.
Why does the recommended amount exceed the raw volume?
Real projects lose material to mixing cups, edge soak-in, seepage, and safety margin. Raw volume alone is often too optimistic.
Should I still check the resin brand instructions?
Yes. Always confirm maximum pour depth, cure conditions, and mix ratio with the product documentation you plan to buy.
