No, water is not used to apply or mix with Purple-K powder, as the dry chemical agent is water-repellent and does not wet with water.
Dry Propellants (https://en.wikipedia.org/wiki/Purple-K)How Purple-K is Applied Dry Propellants: Purple-K (potassium bicarbonate) is stored as a dry powder and is typically pressurized and expelled using dry compressed gases like nitrogen or carbon dioxide.
Simultaneous Deployment: While water and firefighting foam are often used alongside Purple-K during complex Class B (flammable liquid) fires—such as on naval ships or aircraft rescue and firefighting (ARFF) trucks—they are deployed through separate nozzles or complementary systems, rather than mixed together.
