A dispenser for dispensing a fluent material, including a structural body including a fluid circuit for the thick fluent material and a pressure circuit for propelling and dispersing the thick fluent material. Thick fluent material is stored in a hopper and fed by gravity into the fluid circuit. The pressure circuit carrying for example compressed air branches into a first subcircuit arranged to propel thick fluent material towards the discharge nozzle, and a second subcircuit arranged to disperse the thick fluent material as it exists the discharge nozzle. First and second valves respectively control flow of pressurized air in the first and second subcircuits to independently adjust the rate of discharge and dispersion of the thick fluent material.
