Hit exact material yield with the porosity tax baked in, prove due diligence on every slab, and never short-pour a floor again. This estimating and QA spreadsheet covers epoxy, polyaspartic, and urethane-cement work, calculating gallons, Part A/Part B splits, and kit counts while logging substrate moisture and pot life. Works in metric or imperial units.
What's included
- Yield Calculator — enter area, CSP (1–5), and target mils; get exact gallons with porosity tax + 5% waste built in, plus Part A / Part B split and kit count
- Substrate Moisture Log — temp, RH %, dew point and calcium chloride per area; enforces the 5°F-above-dew-point rule (ASTM F2170)
- Pot-Life Matrix — track every batch's mix time, ambient temp, and minutes in bucket so 100%-solids epoxy never hot-pots
- Job Tracker — client, site, system, area, status and amount with an auto-summing total
- Income & Expenses — log payments and costs; monthly net profit totals automatically
- Works in Google Sheets, Excel & Numbers — buy once, no monthly fees, instant download
