What is the ratio of paint to reducer? A mixing ratio given as 4:2:1 normally means 4 parts of base product, 2 parts thinner/reducer, and 1 part hardener. However, some paint manufactures add hardener second, and thinner/reducer last.
What happens if you put too much reducer in paint? Reducer that evaporates too slow and excessive use of reducer are two primary causes of runs and sags. Excessive film thickness: Too much material in full wet coats leads to excess paint that runs.
What is the ratio of paint hardener? As a general guideline, the ratio of color to hardener is 2:1 with a 10 percent addition of thinner. It’s best to not completely fill out the painting cup attached to the gun, because it renders the gun heavy.
