Frequently Asked Questions
What does a 4:1:1 paint ratio mean?
A 4:1:1 ratio means 4 parts paint/base, 1 part hardener, and 1 part reducer. For 12 oz total, you would use 8 oz base, 2 oz hardener, and 2 oz reducer.
How do I measure paint ratios accurately?
Use graduated mixing cups with ratio markings, or a digital scale for weight-based mixing. For automotive paint, paint mixing sticks with ratio markings are the industry standard.
Does the ratio change based on temperature?
Some products require more or less reducer based on temperature. In hot weather, use slower reducer. In cold weather, use faster reducer. Always check the product's Technical Data Sheet (TDS).
