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.

First claim

We claim:

1. 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.

2. The spray application system according to claim 1 , wherein the fluid material comprises an adhesive solution.

3. The spray application system according to claim 1 , wherein the spray pattern comprises a fan pattern.

4. The spray application system according to claim 1 , wherein the container includes one of (i) a pouch configured to store the fluid material and (ii) a pouch-in-a-box system configured to store the fluid material.

5. The spray application system according to claim 1 , wherein the movable cart includes at least four wheels that are configured to stabilize and to move the spray application system when spraying the fluid material onto a roofing surface.

6. The spray application system according to claim 1 , wherein the container is 5 gallons to 25 gallons.

7. The spray application system according to claim 1 , further comprising a hose configured to deliver the fluid material from the container to the at least two spray nozzles.

8. The spray application system according to claim 1 , further comprising an air tube configured to deliver compressed air from the compressor to the at least two spray nozzles.

9. The spray application system according to claim 1 , wherein the peristaltic pump includes (i) a flexible tube configured to deliver the fluid material from the container and to the at least two spray nozzles, (ii) a pump casing that houses the flexible tube, and (iii) a rotating roller, the flexible tube being disposed around the rotating roller.
