Title: Process for applying a smooth coating of plasticized sulfur composition

Abstract: A process for applying a smooth coating of a plasticized-sulfur composition which comprises: (1) conducting a continuous stream of a molten plasticized-sulfur coating composition through a flexible conduit to a spray nozzle; (2) injecting a substantially inert pressurized gas into the conduit proximate to the nozzle at a flow rate such that the ratio of the flow rate of the coating composition in cubic feet per minute to the flow rate of the gas in cubic feet per minute is about 0.02/1 to about 1/1; and (3) spraying the coating composition and the gas from the conduit through the nozzle onto the surface to be coated.
