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.
Typical Film & Pour Guides
- Seal coat: 0.3–0.5 mm (thin, to close pores)
- Flood coat: 1–2 mm (tabletops, art coats)
- Self-level floor: 2–3 mm
- Deep-pour casting: 25–50 mm per layer (check product datasheet)

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.
Important Estimate Disclaimer
The results provided by this calculator are intended as general estimates only and should not be considered precise engineering measurements. Actual material requirements, costs, and quantities can vary significantly based on site conditions, local building codes, soil type, reinforcement requirements, climate exposure, and the intended use of your project.
These calculators are designed to help you plan and budget your project more effectively, but they do not replace professional advice from a qualified contractor, engineer, or building inspector. Always verify your calculations and assumptions with trained professionals before placing material orders or commencing construction.
For more information on the assumptions, formulas, and data used in these tools, see our Data Sources and Methodology pages.
Material estimates, cost figures, and volume calculations are approximate and may not reflect your actual requirements. Always double-check dimensions and project-specific needs, and consider adding a contingency allowance for waste, over-excavation, and unforeseen conditions.
If you are unsure about any aspect of your project — including structural requirements, reinforcement needs, drainage, or load-bearing capacity — consult with a licensed professional before proceeding.
