We do not recommend that you use denatured alcohol/ethanol in the Steri-Fab Continuous Action Sprayer (CAS) because of its flash point. We did speak to the manufacturers of the two lines of sprayers we carry and both said that while they cannot truly recommend a sprayer for your needs because of liability issues, some professionals do use the Chapin 3.5 Gallon Concrete Sprayer 1949 to spray diesel fuel, so it might be used for ethanol as well.
