Job & Mix Reference
Optional details for saved mixes, CSV exports, and printed records.
Mixing Ratio
Enter the ratio exactly as specified in the product technical data sheet (TDS). No manufacturer or industry ratio is preset.
Important: Do not treat a volume ratio as a weight ratio, or a weight ratio as a volume ratio, unless the product manufacturer explicitly allows it. Use the basis stated in the product TDS.
Target Amount & Reducer
Choose whether the target is the final mixed amount or the 2K base mix before reducer, then enter any reducer percentage required by the product TDS.
Enter 0 if no reducer or thinner is used.
Reducer calculation: This tool calculates reducer / thinner as a percentage of the 2K base mix (paint + hardener). If the product TDS uses a different basis, follow the manufacturer instruction instead.
