Epoxy Coverage Calculator
Please use this Epoxy Resin Calculator as a reference guide only. We have calculated for loss due to mixing and project overflow. Our general epoxy coverage rule is 12 square feet per mixed gallon at 1/8 inch. Each project is unique and some surfaces are more porous than others which may require additional epoxy. When in doubt, reach out. Ask Us Questions Here.
How To Calculate Epoxy Resin Coverage
Calculating how much epoxy you'll need for a project is based on volume. We get many questions asking how much epoxy is needed for a specific square foot project, but many neglect to consider thickness. Additionally, many neglect to consider whether a seal coat is necessary as well as the loss due to epoxy flowing over the sides/edges of the project. The coverage calculator above does our best to account for the loss due to these factors.
Better To Have More Than Not Enough
Underestimating the amount of epoxy needed can end up costing more in the long run. When pouring a project and running out mid-project will often require the entire project to be poured again. Matching up epoxy pours (especially on a surface like a table top or bar top) can be extremely difficult and often will leave behind a visible line where the two pours match up. The proper way to address this is to sand the entire surface (once cured, of course) and pour the entire surface again. If this were to happen, we recommend starting the pour in the low area (where epoxy did not cover during the initial pour). This is the best way to prevent a line from appearing in the final coat. However, each project is unique. Please feel free to contact us with specific project questions.
Is A Seal Coat Needed?
Failing to properly seal a project can result in excess bubbles in the final coat. More times than not, a seal coat is necessary. A thin seal coat helps to fill in and seal up porous areas of the project. A seal coat is especially necessary when pouring epoxy over wood, encapsulation projects and other porous substrates. Although thin, this is additional epoxy that needs to be accounted for when calculating total epoxy necessary for a given project.
Epoxy Overflow Allowance
Unless the project will be dammed or framed, an overflow allowance must be accounted for in the epoxy calculation. Many coating projects allow the epoxy to flow over the sides, coating the edges of the project. Calculating overflow loss can be tricky as loss is dependent on the project and the user. Again, it's best to overestimate, which our calculator does.
Our epoxy requires thin pours of no more than 1/4 inch per application (1/8" for UV PRO Formula). For those projects which require thicker applications, multiple layers must be poured. Our epoxy coverage calculation accommodates up to 1" thick. For those that require even thicker pours, you may want to consider a thinner casting resin (coming soon).
