PROJECT QUANTITY & KIT COMPARISON

Buy the right amount of epoxy.

Estimate your quantity. Compare kit costs and what’s left over.

01

Your project

What are you making?

Measure the top surface only. This estimate assumes a sealed surface with contained edges.

10% is an example you can change, not a manufacturer recommendation. Seal coats, edge overflow, and final coatings are not included.

Use the temperature you expect during application. A matching range does not confirm all working conditions.

How the estimate works

Length × width × thickness gives the base volume. One US gallon contains 231 cubic inches. Your chosen allowance is added separately.

Quantities include both resin and hardener. The calculator compares complete kits of the same product; it never combines different resin systems.

Real consumption depends on your surface and application. Confirm coverage and application instructions before buying.

Check one coat or river layer at a time. Products outside checked depth or temperature limits are excluded from price ranking. Remaining options still need the listed application checks; none is a guarantee of suitability.

Leftover means unused material in the purchased kits. Mix only the amount allowed by the product instructions—not all purchased material at once.
