Abstract
This invention relates to a method and system of applying a fluid material to a roofing surface. By modifying a peristaltic pump-driven sprayer device, a fluid material having a viscosity of 10,000 to 40,000 centipoise at 25° C. can be effectively sprayed onto a roofing surface. Additionally, the use of a modified peristaltic pump-driven sprayer device allows for the fluid material to be applied onto the roofing surface at a faster rate than other spraying methods.
Claims9
A spray application system comprising:
- (a) a movable cart;
- (b) a container configured to hold a fluid material, the container being positioned on the movable cart;
- (c) a compressor configured (i) to deliver compressed air to the spray application system and (ii) to provide power to pump the fluid material through the spray application system via a peristaltic pump disposed within the compressor and configured to pump the fluid material, the compressor being positioned on the movable cart;
- (d) at least two spray nozzles that are each connected to the peristaltic pump via a hose, with each of the spray nozzles being configured to spray the fluid material onto a roofing surface;
- and
- (e) an elliptical tip attached to each of the at least two spray nozzles, with each elliptical tip being configured to provide a spray pattern of the fluid material onto a roofing surface,
- wherein the spray application system is configured to spray the fluid material at a flow rate of 0.5 to 10 gallons per minute, with the fluid material having a viscosity of 10,000 to 40,000 centipoise at 25° C.
