How much epoxy for a 60 inch round table?

Short answer

A 60 inch round table needs about 1.81 gallons of tabletop epoxy for one 1/8 inch flood coat over 19.6 square feet, including 19.6 fluid ounces of drips off the rim.

How to work it out

  1. Top: π × (60 in ÷ 2)² = 2,827 sq in (19.6 sq ft)
  2. 19.6 sq ft × 1/8 in × 1 coat = 353 cu in = 1.53 gal
  3. Edge length: π × diameter = 188 in (15.7 ft)
  4. Drips: 15.7 ft × 1.25 fl oz/ft × 1 coat = 19.6 fl oz
  5. Film on the sides: 188 in × 1.5 in × 1/32 in × 1 coat = 4.9 fl oz
  6. (1.53 gal + 19.6 fl oz + 4.9 fl oz) × (1 + 5% bucket/other) = 1.81 gal
  7. Total: 1.81 gal → 2 × 1 gal kits
  8. Batches: 1.81 gal per coat ÷ 1 gal → 2 per coat, each A 1.81 qt (4.34 lb) + B 1.81 qt (3.58 lb)
  9. Mix ratio 1 : 1 by volume, SG A 1.15 / B 0.95 (typical, not published by the maker — type your data sheet’s SGs for exact weights) → Part A 0.9 gal (8.67 lb) + Part B 0.9 gal (7.17 lb)

A 60 in round seats six to eight, and its top is about 19.6 sq ft — more than a 6 ft rectangular dining table. Two 1-gallon kits cover the flood coat with only about 24.6 fl oz to spare, so a seal coat on bare wood pushes you to a third kit.

Adjust for your project

in
Straight across the widest part.
Leave at 1/8 in unless your epoxy’s label says otherwise.
1 is normal. Use 2 for extra depth or to bury bottle caps or photos.
A thin first coat brushed or scraped into bare wood, so air in the grain doesn’t bubble up into the clear coat.
gal
Total of both bottles together. Most “1 gallon kits” are ½ gal resin + ½ gal hardener — enter 1. If the listing says 1 gal of EACH, enter 2.
More options: edges · edge · waste …
Most tops are poured so the epoxy runs over and coats the sides. A tape dam keeps it on the top only.
in
How tall the edge is — usually the thickness of the top.
%
Bucket and cup residue and other small losses. Edge drips are worked out separately from the edge length.
Fills in the mix ratio, weights and depth limits from the maker’s published data. Always check the data sheet that comes with your batch.
Only changes the Part A / Part B split — it’s printed on the kit. Tabletop and art resins are usually 1:1; deep pour often 2:1.
From the TDS, in g/ml. Leave blank for 1.15 (typical, not published by the maker).
From the TDS, in g/ml. Leave blank for 0.95 on 1:1 kits or 0.97 on other ratios (typical, not published by the maker).
gal
Resin + hardener mixed in one bucket. Big batches heat up and thicken sooner, so pros mix the next one while the last is being poured.

  • What to buy: 2 × 1 gal tabletop epoxy kits. Each kit has both bottles (resin + hardener) — you don’t buy them separately. Looking at a different kit size? Change Kit size above.
  • Pouring onto bare wood? Pick a seal coat above — it stops air in the grain bubbling up into the clear coat.
  • Each coat is 2 batches. Mix the next one while the last is being spread and pour them back to back, so the wet edges merge before they start to thicken.

Tabletop / bar top epoxy kitYou need 1.81 gal, so 2 × 1 gal kits — or price one bigger kit, which is often cheaper per gallon. Self-leveling tabletop epoxy is made for 1/8 in coats; a deep-pour resin would run off the edges for days.

What to know about a 60 inch round table

Going from 48 to 60 in adds a foot of diameter but more than half again in area: 19.6 sq ft against 12.6 on How much epoxy for a 48 inch round table. The flood coat is 1.53 gallons before drips and 1.81 after. With an open-grain seal coat it comes to 2.16 gallons, just over a 2-gallon kit, so buy a 2-gallon plus a 1-gallon kit, or three 1-gallon kits.

Reach is the problem people miss. The centre is 30 in from the edge all the way round — a long stretch over a wet surface. Pour the first batch in the middle and spread it outward with a spreader or a stiff squeegee, then pour the second batch around it. Don’t lean over the wet rim to reach in; sleeves and forearms drag through it.

Many 60 in rounds carry a lazy Susan. Coat the turntable separately rather than with the top, and keep epoxy away from the bearing so it still turns. A round this size also usually sits on a big pedestal or four legs; wrap them before pouring.
