Application system

1. An application system for applying a substance over a predetermined surface, comprising:

a frame movable over the predetermined surface;

a pressurized carrier source;

a vessel containing the substance;

a first conduit for conveying the substance from the vessel to at least one nozzle and a second conduit for conveying a pressurized carrier from the pressurized carrier source to the at least one nozzle for applying a mixture of the pressurized carrier and the substance over the predetermined surface; and

a cover laterally surrounding the at least one nozzle for minimizing overspray of the mixture, the cover includes a first cover portion and a second cover portion that are moveable with respect to each other;

wherein the frame carries the pressurized carrier source, the vessel, the first conduit, the second conduit, and the cover.

2. The application system of claim 1 , wherein the application system is self-contained.

3. The application system of claim 1 , wherein the pressurized carrier source is an air compressor.

4. The application system of claim 3 , wherein the air compressor is battery powered, powered by a gas source, a liquid source, or a combination thereof.

5. The application system of claim 1 further comprises a plurality of wheels rotatably connected to the frame for permitting movement of the frame over the predetermined surface.

6. The application system of claim 5 further comprises a castor rotatably connected to the frame.

7. The application system of claim 1 , wherein the cover is movable relative to the frame between an operating position and a first transport position.

8. The application system of claim 7 , wherein the cover is movable relative to the frame between the first transport position and a second transport position.

9. The application system of claim 1 , wherein the frame further comprises a handle.

10. The application system of claim 1 further comprises a heater positioned over at least a portion of the vessel for controlling a temperature of the substance.

11. The application system of claim 1 further comprises a control assembly for selectively controlling the flow of the pressurized carrier from the pressurized carrier source to the at least one nozzle.

12. The application system of claim 11 , wherein the control assembly includes a control handle movable between an operating position and a shutoff position.

13. The application system of claim 1 further comprises a spray nozzle protector positionable over a portion of each of the at least one nozzle for preserving the at least one nozzle during non-operation of the application system.

14. The application system of claim 1 , wherein the predetermined surface is a predetermined horizontal support surface.

15. The application system of claim 13 , wherein the substance is a roofing adhesive or a roofing sealant.

16. The application system of claim 13 , wherein the cover is movable relative to the frame between an operating position and a first transport position.

17. The application system of claim 16 , wherein the cover is movable relative to the frame between the first transport position and a second transport position.

18. The application system of claim 1 , wherein the first cover portion is rotated in a first direction and the second cover portion is rotated in a second direction different than the first direction.

19. The application system of claim 1 , wherein the first cover portion and the second cover portion are rotated approximately 90 degrees.

20. The application system of claim 1 , wherein the first cover portion and the second cover portion are rotated about respective pivotable connections positioned at each of opposed ends of the first and second cover portions.
