How much resin for an 8 × 10 canvas?

Short answer

An 8 × 10 in canvas needs about 6.1 fluid ounces of mixed resin for a full 1/8 inch coat, including 10% extra — 3.05 fluid ounces each of Part A and Part B for a 1:1 resin. An 8 fl oz kit covers it with 1.9 fl oz to spare.

How to work it out

  1. Area: 10 in × 8 in = 80 sq in
  2. 80 sq in × 1/8 in = 10 cu in = 5.54 fl oz; + 10% = 6.1 fl oz (≈ 6.68 oz on a scale)
  3. 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 3.05 fl oz (3.66 oz) + Part B 3.05 fl oz (3.02 oz)

An 8 × 10 is the size of a standard photo print and a common small study panel, so it is often the first thing people coat with resin. The amounts are small enough that measuring becomes the hard part: about 3 fl oz of each part barely registers on a large graduated cup, so use small cups marked in milliliters, or weigh it on a scale.

Most resin boxes’ coverage claims assume a thin coat — pick 1/16 in to match the box. 1/8 in is a full, glassy, self-levelled coat and uses about twice as much.

What to know about an 8 × 10 canvas

An 8 fl oz kit — 4 fl oz of resin plus 4 fl oz of hardener — covers one full coat with about 1.9 fl oz left over. That is margin for what clings to the cup, not enough for a second piece. A 16 fl oz kit coats two 8 × 10s at full thickness from one mixing cup, which is the cheaper way to practise: mix once, pour both, and compare how each one levels.

The sides matter more at this size than on any bigger canvas. The top is only 80 square inches, but the four edges of a 3/4 in panel add another 27 square inches (a third more), and a 1 1/2 in deep canvas adds 54 square inches, two thirds more. If you want a glossy wrapped edge, use the with-sides figure below. If you would rather tape the edges and let the resin dome — guided right to the rim and held there by surface tension, as ArtResin describes — the top-only figure is the one to mix.

The usual mistake here is mixing too little. Many resin labels give a minimum batch for a reliable cure, and on a 1 or 2 fl oz batch a small measuring error throws the ratio off far more than it would in a big one. Mixing the full 6 fl oz, or pouring two panels from one cup, is safer than trying to mix exactly what one panel needs. One batch is plenty at this size — there is too little resin in the cup for heat build-up to shorten your working time.

Frequently asked questions

How much resin for an 8x10 canvas at 1/16 inch?

About 3.05 fluid ounces with 10% extra — 1.52 fl oz of each part. At 1/16 inch you spread it with a spreader or gloved hand rather than letting it self-level.

How much resin for an 8x10 canvas with the sides coated?

About 10.2 fluid ounces for a full 1/8 inch coat over the top and 1 1/2 inch sides, with 10% extra. That is 2 kits of 8 fl oz, so a single 16 fl oz kit is the simpler buy.
