How much epoxy to coat a 200 × 100 cm table?

Short answer

A 200 × 100 cm table needs about 7.22 liters of tabletop epoxy for one 3 mm flood coat over 2 square metres, including 688 milliliters of drips off the 6 m edge.

How to work it out

  1. Top: 200 cm × 100 cm = 2 m²
  2. 2 m² × 3 mm × 1 coat = 6,000 cm³ = 6 L
  3. Edge length: 2 × (length + width) = 6 m
  4. Drips: 6 m × 121 ml/m × (3 mm ÷ 3.175 mm) × 1 coat = 688 ml
  5. Film on the sides: 6 m × 4 cm × 0.79 mm × 1 coat = 191 ml
  6. (6 L + 688 ml + 191 ml) × (1 + 5% bucket/other) = 7.22 L
  7. Total: 7.22 L → 2 × 4 L kits
  8. Batches: 7.22 L per coat ÷ 4 L → 2 per coat, each A 1.81 L (2.08 kg) + B 1.81 L (1.72 kg)
  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 3.61 L (4.15 kg) + Part B 3.61 L (3.43 kg)

Metric makes coatings easy to check in your head: every square metre at 3 mm is 3 liters. Two square metres is 6 liters before drips, and the 6 m edge sheds about 0.69 liters more — so a single 5 liter kit won’t do it, and with the 4 liter kits assumed here you need two, with 0.78 liters left over.

Adjust for your project

Measure the top surface only — drips over the edges are covered by the extra allowance.

Measure the top surface only — drips over the edges are covered by the extra allowance.
Leave at 3 mm 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.
L
Total of both bottles together (e.g. 2 L + 2 L = 4).
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.
cm
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).
L
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 × 4 L 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 7.22 L, so 2 × 4 L kits — or price one bigger kit, which is often cheaper per liter. Self-leveling tabletop epoxy is made for 3 mm coats; a deep-pour resin would run off the edges for days.

What to know about a 200 × 100 cm table

Two metres by one is a common size for a dining table seating six to eight, and it is close to 79 × 39 in — a little bigger than the top on How much epoxy for a 6 ft dining table. Kit sizes vary by brand, and many are sold by weight rather than volume. Put your own kit size into the calculator; if the box is labelled in kilograms, mixed epoxy is typically about 1.1 kg per liter, so check the density on the data sheet and convert.

Use the 3 mm option unless your label says otherwise. If you switch over from US units, the calculator keeps 3.2 mm, which is exactly 1/8 in; on this table that adds about 0.4 liters and cuts the spare in two 4 liter kits to 0.37 liters — a tight fit — which matters if you are following an American guide or a US product sheet.

With an open-grain seal coat on bare oak, the total becomes 8.72 liters — three 4 liter kits. Pour a top this size as two batches starting at one end: at 2 m long the far end is out of reach from the near end, so walk the batches down the length rather than dumping everything in the middle.
