This is a calculator for a GFRC mix design. For a complete video course on how to make GFRC, including this calculator, see Professional GFRC for Concrete Countertops.
This convenient, easy-to-use GFRC calculator:
- Eliminates the need for math and formulas
- Reduces costly mistakes
- Saves time
From-scratch GFRC mix formulas are public knowledge, but they are not easy to use. You have to fumble with math and formulas for your mist coat and your backer coat, causing confusion and mistakes.
The calculator computes exactly how much of each ingredient, including pigments, and produces a printable batch report for you to use while mixing. All you do is enter the size of your project, and the calculator does the rest. You don’t have to do any math, and you’re assured of a precise mix every time.
The calculator also computes exactly how much each of your mix ingredients cost, helping you analyze your profitability. And, it automatically calculates the number of batches based on your gun or mixer size. You can save your batch report for each project so that you have a record of exactly what you did for that client. Both English and metric weights are provided.
Calculator comes as downloadable Microsoft Excel spreadsheet. Compatible with Windows programs and can be used on a Mac with Microsoft Excel emulator.
