  6. You can mix only 8 ounces of floetrol with every gallon of water-based paint you use to use a brush or roller. You must start with just 8 ounces and gradually increase the pouring, as per the amount of paint you will use further in the application. 
  7. Keep a constant check upon the flow of your paint. If it is already thin enough, then you can stop pouring floetrol.

  3. You should not pour more than 1 quart of floetrol to 1 gallon of latex paint by any chance. 
  4. Keep a constant check on the thinness of your paint. When you find the flow thin enough to be used for spray or brush, stop the pouring.
