Resin Mix-Ratio & Cure Log
A free printable PDF with the two pages every resin studio needs — a mix-ratio reference & worksheet (the resin:hardener math for any pour) and a cure log. An honest "studio reference, not certification — follow your resin's label & SDS" frame. It is the lite cut of the full Resin & Epoxy Maker's Workbook.
A free, ungated PDF for the resin & epoxy maker who eyeballs the ratio and pours by feel. It gives you the two things that decide whether a pour comes out glass-hard or stays forever soft. First, a mix-ratio reference and worksheet: the one formula (Part A = total × A ÷ (A+B); Part B = total × B ÷ (A+B)), a quick-reference table of the common resin systems and their typical ratios, working times, and safe pour depths, and a fill-in worksheet to work out any pour by hand. Second, a print-and-use cure log — one row per pour for the resin, the ratio, the batch size, the room's temperature and humidity, the demold time, and how it came out — because two identical pours can come out clear or hazy for no reason except the conditions they cured in. It is built on an honest premise: this is a studio reference, not certification — every ratio, pour depth, and cure time is a typical starting point, so always follow your resin's label and SDS, and resin is not food-safe by default. It is the lite cut of the paid Resin & Epoxy Maker's Mix, Cure & Cost Workbook — a mix-ratio calculator, a 10-system reference, a pigment & additive load calculator, a full cure & troubleshooting reference, inventory, and batch & per-piece pricing.
- A mix-ratio reference — the one formula, a worked example, and a quick-reference table of common resin systems with their typical ratios, working times, and safe pour depths
- A mix-ratio worksheet — fill in your resin's ratio and the total you want, and work out the exact resin and hardener amounts for any pour
- A print-and-use cure log — one row per pour for the resin, ratio, batch, room temp, humidity, demold time, and result, so a failed pour becomes a lesson
- Honest framing throughout: a studio reference, not certification — every ratio and cure time is a typical starting point, follow your resin's label & SDS, and resin is not food-safe by default
- A clear upgrade path: this is the free cut of the full Resin & Epoxy Maker's Workbook, available on the Ardent Workshop storefront
This starter is a record-keeping tool and studio reference, not certification. Every mix ratio, pour depth, and cure time is a typical starting point — always follow your specific resin's label and safety data sheet (SDS). Resin and its hardener carry real hazards (skin/respiratory sensitization, fumes, sanding dust, and a curing heat that can overheat or burn); wear nitrile gloves, ventilate, and never exceed the stated pour depth. Resin is not food-safe by default. Costing and pricing examples are illustrative, not financial advice. Not affiliated with or endorsed by any resin, pigment, or mold manufacturer, or any marketplace.
The mix decides almost everything
More resin failures trace back to the mix than to anything else — a ratio that was off, or a cup that wasn't scraped. A mix ratio is just a proportion: how many parts of resin (Part A) to hardener (Part B). To mix a batch, pick a total amount and split it in that ratio. This starter gives you the one formula, a worked example, a quick-reference of common resin systems and their typical ratios, and a fill-in worksheet to work out any pour by hand.
The one rule that saves batches: more hardener does not make resin cure harder or faster — the opposite. Measure precisely the way the label says (by weight on a scale, or by volume in cups — they are not the same), and mix the full time, scraping the cup walls and bottom, or you'll get soft, sticky patches.
The cure happens while you're not watching
Two identical pours can come out glass-clear and rock-hard, or hazy, dimpled, and soft, for no reason except the temperature and humidity of the room overnight. The print-and-use cure log captures the resin, the ratio, the batch, the room's temperature and humidity, the demold time, and the result — so the patterns show themselves and a failed pour becomes a lesson instead of bad luck repeated.
A studio reference, not certification
This is a record-keeping tool, not a substitute for your resin's instructions or materials-safety training. Every ratio, pour depth, and cure time is a typical starting point — your specific product's label and safety data sheet always win. Resin and its hardener are skin and respiratory sensitizers and carry real hazards (fumes, sanding dust, and a curing heat that can overheat or burn): wear nitrile gloves, ventilate, and never exceed the stated pour depth. Resin is not food-safe by default.
Want the full version?
This free starter is the mix-ratio pages and the cure log. The full Resin & Epoxy Maker's Mix, Cure & Cost Workbook is the whole business side of a studio: a mix-ratio calculator that does the math for any pour, a 10-system resin reference, a pigment & additive load calculator with an over-load "won't cure" flag, a full cure & troubleshooting reference (bubbles, amine blush, soft cure, yellowing, exotherm) with this log built in, a mold & materials inventory with a low-stock flag, and a batch & per-piece cost & pricing calculator that finally pays you for your finishing time — a working Excel workbook (8 tabs) plus five PDF guides, evergreen. Available on the Ardent Workshop storefront.

A spreadsheet is a wonderful place to start a studio and a hard place to scale one. Ardent Seller turns these pages into a living system: your resin formulas and pour methods become reusable procedures, your resin, hardener, pigments, and molds become tracked inventory that draws down as you make, your true cost per piece is computed for you, and your pieces are tracked from the studio to the sale. Start free — no credit card required.
Recipes & procedures
Store your resin formulas and pour methods as reusable procedures, so a batch mixes the same way every time.
Inventory
Track resin, hardener, pigments, and molds so a pour never runs dry mid-job — and so your per-piece costs are real.
Cost per piece
Roll resin, mold, finishing, labor, and overhead into a true cost per piece, so the price you set actually pays you for the sanding and polishing.
Frequently asked questions
Is this really free?
Yes — the starter is a free PDF download with no email required. It is the lite cut of the paid Resin & Epoxy Maker's Workbook, which adds a live mix-ratio calculator, a 10-system reference, a pigment & additive load calculator, a full cure & troubleshooting reference, inventory, and batch & per-piece pricing.
What exactly is in the free starter?
A mix-ratio reference and fill-in worksheet (the resin:hardener math for any pour, plus a quick-reference of common resin systems) and a print-and-use cure log to record every pour and the conditions it cured in.
Will these ratios and cure times work for my resin?
They are typical starting points to teach the method — your specific product's label and safety data sheet always win. Ratios, pour depths, and cure times are set by the exact resin in your hand; always measure and cure the way your label says, and never exceed its maximum pour depth.
Is resin food-safe?
Not by default. Only a fully cured, manufacturer-certified resin used exactly as specified may be rated for incidental food contact — proving that for your use is your responsibility. This is a record-keeping tool; it cannot tell you a surface is food-safe.
Does it expire or is it tied to a year?
It never expires. It is evergreen — mix ratios and cure chemistry do not change, and the logs use a date column you fill in yourself.
