🧪 Resin Calculator

Plan coatings, castings, and river tables. Get total resin, Part A/B by volume or weight, layer plan, and pigment amounts.

Common: seal coat 0.3–0.5 mm; flood coat 1–2 mm; self-level floor 2–3 mm.

Default typical epoxy resin ~1.05–1.15 kg/L.

Hardeners often slightly lighter.

Used only when mixing by weight to convert total volume → mass.

Seal-coat absorption or container losses.

Typical 1–5% max; follow manufacturer guidance.

Used for coatings. Casting/River use their own max layer fields above.

Resin Calculator – Mix Ratios, Layers, and Coverage

Enter your dimensions, select mix by volume or weight, set densities, and plan layers with your product’s max pour depth. The calculator outputs total resin, Part A/B amounts (both volume and weight), pigment quantity, a layer plan, and suggested kit size.

FAQs

Volume vs Weight mixing?
If your resin specifies a volume ratio (e.g., 2:1), use “By Volume.” For ratios listed in grams (e.g., 100:45), choose “By Weight.”

Why a max pour depth?
Thick pours can overheat (exotherm). Plan multiple layers within the manufacturer’s safe depth.

How much pigment should I add?
Most systems recommend 1–5% by total resin. Excess pigment can inhibit cure—follow your product’s datasheet.
