Enter square feet (or m²) and coat thickness to see how many gallons of epoxy you need, with edge runoff, waste, and cost for tabletops, bar tops, and countertops.
Table Top Epoxy Calculator
Use this page for table top resin work where the job is really about coverage, leveling, clarity, and finish build. It is tuned for flood coats and finish pours, not thick casting sections or cavity fills.

Next Step
Match the result to the right resin class
Use the estimate to narrow the resin class first. Then confirm product limits, cure behavior, and measurement assumptions before you make a buying decision.
Measurement diagram
Separate the surface from the edges
For a rectangular 72 × 24 in top, area is 12 ft². A theoretical 1/8 in wet layer is 216 in³ = 0.9351 gal before edges and losses. The example 8% waste plus 4% edge/runoff allowance gives 1.0473 gal. A round 24 in top has 3.1416 ft² instead: choose the round dimensions mode. If you know a product's published coverage, switch to label coverage rather than assuming a wet thickness. Raised edges, end grain and an earlier seal coat need their own measurements.
Product data before mixing
Use the exact product documentation for mixing basis, maximum layer depth, mixed batch volume and cure or recoat conditions. A dimensional estimate and a purchase allowance do not supply those material limits.
What this calculator covers
- Best for flood coats, finishing pours, and tabletop resurfacing jobs.
- Translates surface size and target thickness into a usable resin order estimate.
- Keeps edge runoff, perimeter waste, and top-coat product fit visible in the calculation.
How to measure or set the inputs
- Measure every face that will actually receive resin, including wrap edges if they will be coated.
- Enter the finished flood-coat thickness you want after leveling, not the full substrate thickness.
- Use a higher waste setting if you expect strong edge runoff or if the piece has uneven perimeter detail.
Common mistakes that cost money
- Using deep-pour logic for a thin finish job.
- Ignoring edge runoff and then under-ordering material.
- Using a tabletop page for a river channel or thick embedded pour.
Project checklist before you buy
- Confirm the mold or surface is sealed before mixing resin.
- Measure depth twice at the deepest point of the project.
- Add extra material for waste, seepage, and edge soak-in.
- Confirm the resin type matches the intended pour depth.
- Prepare cups, stir sticks, gloves, and a level work surface.
FAQ
Questions people ask before buying epoxy
Is table top epoxy the same as deep pour resin?
No. Table top products are typically for thin finish layers, while deep pour products are formulated for thicker pours.
Should I count table edges in the estimate?
Yes, if the edges will actually receive resin. Table edges and runoff are often the reason a flood-coat estimate comes in short.
What if the table has a small knot or recessed area?
Use this page for the main surface coat, then add a separate void-fill or volume estimate if the recess is deep enough to behave like a cavity rather than a finish layer.
