How Much Resin Do I Need for a Table?
Table projects use epoxy in two ways: as a surface coating (flood coat) or as a fill material (river table channel). The amount you need depends on table size, coat thickness, and whether you're doing a seal coat first. This guide gives you pre-calculated amounts for every common table size.

Calculate Table Resin →The Formula for Table Flood Coats
For a flat tabletop flood coat, the formula is straightforward:
Pour depth: seal coat ≈ 0.03 in | flood coat ≈ 0.125 in (1/8 in)
Always add 10% to the calculated amount for mixing waste, drips off the edges, and uneven spreading.
Flood Coat by Table Size
One flood coat at 1/8 inch is the standard for a self-leveling epoxy table finish. Most quality table builds use a seal coat plus one or two flood coats.
| Table Size | Seal Coat | 1 Flood Coat | 2 Flood Coats | Total (seal + 2 floods) |
|---|---|---|---|---|
| 18×18 in (end/side table) | 4 fl oz | 14 fl oz | 28 fl oz | 32 fl oz |
| 20×40 in (small coffee table) | 9 fl oz | 28 fl oz | 56 fl oz | 65 fl oz |
| 24×48 in (coffee table) | 16 fl oz | 51 fl oz | 102 fl oz | 118 fl oz |
| 30×60 in (small dining) | 25 fl oz | 75 fl oz | 150 fl oz | 175 fl oz |
| 30×72 in (standard dining) | 30 fl oz | 90 fl oz | 180 fl oz | 210 fl oz |
| 36×72 in (large dining) | 35 fl oz | 108 fl oz | 216 fl oz | 251 fl oz |
| 36×84 in (large dining) | 42 fl oz | 126 fl oz | 252 fl oz | 294 fl oz |
| 48×96 in (conference / banquet) | 64 fl oz | 193 fl oz | 386 fl oz | 450 fl oz |
All amounts include 10% waste buffer. Seal coat assumes 1/32 inch depth.
Bar Top Resin Amounts
Bar tops are measured in linear feet (typically 22–24 inches deep). Coverage below is for 24-inch deep bars at 1/8 inch per coat.
| Bar Top Length | Seal Coat | 1 Flood Coat | 2 Flood Coats |
|---|---|---|---|
| 4 linear ft | 8 fl oz | 26 fl oz | 52 fl oz |
| 6 linear ft | 11 fl oz | 38 fl oz | 76 fl oz |
| 8 linear ft | 15 fl oz | 51 fl oz | 102 fl oz |
| 10 linear ft | 19 fl oz | 64 fl oz | 128 fl oz (1 gal) |
| 12 linear ft | 23 fl oz | 77 fl oz | 154 fl oz |
| 16 linear ft | 30 fl oz | 102 fl oz | 204 fl oz |
| 20 linear ft | 38 fl oz | 128 fl oz (1 gal) | 256 fl oz (2 gal) |
River Table Channel Resin
River table builds require filling a channel between two slabs. Measure the average width, total length, and planned fill depth of the channel. The formula adds 15% for irregular wood edges.
| Table Length | Channel Width | Channel Depth | Resin Needed |
|---|---|---|---|
| 4 ft (48 in) | 6 in | 1 in | ~36 fl oz |
| 5 ft (60 in) | 8 in | 1.5 in | ~90 fl oz |
| 6 ft (72 in) | 8 in | 1.5 in | ~108 fl oz |
| 6 ft (72 in) | 10 in | 2 in | ~180 fl oz |
| 7 ft (84 in) | 10 in | 2 in | ~210 fl oz |
| 8 ft (96 in) | 12 in | 2 in | ~288 fl oz (~2.25 gal) |
Add the flood coat amount from the dining table table above to get your total resin for a river table build. See the full river table guide →
Tip: For river tables, use a deep-pour or ultra-clear resin for the channel fill (up to 2 inches per pour) and switch to a standard table-top epoxy for the flood coat. Mixing resin types between steps is normal and often produces better results than using one product for everything.

Material Plan
| Step | Depth | Resin Amount |
|---|---|---|
| Seal coat (locks grain, prevents bubbles) | ~1/32 in | 30 fl oz |
| 1st flood coat (self-leveling) | 1/8 in | 90 fl oz |
| 2nd flood coat (final finish) | 1/8 in | 90 fl oz |
| Total | 210 fl oz (~1.6 gal) |
Purchase 2 gallons to cover the 10% buffer and have leftover for touch-ups. Allow 24–48 hours cure time between coats.
Frequently Asked Questions
How many ounces of resin do I need for a dining table?
A standard 30×72 inch dining table needs about 90 fl oz for one flood coat at 1/8 inch. With a seal coat and two flood coats (the typical quality finish), plan on 210 fl oz total — just under 1.7 gallons. Buy 2 gallons to have a buffer.
How much resin do I need for a river table?
River tables need resin for two parts: the channel fill and the tabletop flood coat. A 6-foot table with an 8-inch wide channel at 1.5 inches deep needs about 108 fl oz for the channel, plus another 90–180 fl oz for the flood coat, totaling 200–290 fl oz depending on coat count.
What is a seal coat and how much resin does it use?
A seal coat is a thin initial layer (1/32 inch or less) that locks the wood grain and prevents air bubbles from rising into flood coats. It uses about 20–25% of what a flood coat needs. For a 30×72 inch table, the seal coat takes roughly 30 fl oz vs 90 fl oz for a full flood coat.
