A method of using a coating applicator to coat a standing seam rib roof comprising:
- a) positioning a coating applicator on a corrugated standing seam rib roof having a rib dividing the corrugated standing seam rib roof into a first area and a second area, each of the corrugated first area and the corrugated second area configured as each having at least one ridge and at least one groove adjacent each side of the at least one ridge, the rib having a first end and second end, the coating applicator positioned initially proximate a first end of the rib, the coating applicator further comprising:
- i. a carriage having at least a first wheel, a second wheel and a third wheel mounted therein wherein the first wheel and the second wheel are positioned opposite each other and configured to roll in the at least one groove adjacent each side of the at least one ridge;
- ii. a center support assembly, wherein the center support assembly is mounted to the carriage;
- iii. a boom having a center section, a first section, a second section and a counterweight, the boom is mounted on the center support assembly;
- iv. a handle, the handle configured to engage with the center support assembly and to control a direction of travel of the applicator during use wherein the third wheel is aligned with the handle and positioned behind the first wheel and second wheel;
- v. a fluid delivery arrangement, the fluid delivery arrangement further comprising:
- 1. An input coupling, the input coupling to allow connection with a pressurized fluid delivery system;
- 2. A fluid conduit having at least a first end and a second end, the fluid conduit in fluid communication with the input coupling at the first end;
- 3. At least one nozzle configured for delivery of a pressurized fluid to a surface positioned adjacent the at least one nozzle, wherein the at least one nozzle is attachable to the boom and is in fluid communication with the second end of the fluid conduit;
- and,
- vi. the fluid delivery arrangement is affixed to at least the boom of the applicator;
- b) connecting the coating applicator to a pressurizing fluid supply source to provide pressurized coating material to the coating applicator;
- c) applying the coating to a first panel of the first area of the standing rib roof in a first direction from the rib to an eve of the roof with the coating applied on a panel adjacent a first edge of the first area, the second section of the applicator configured with at least one nozzle for application of the coating;
- d) repositioning the coating applicator to a next panel adjacent the first panel of the first area of the standing rib roof;
- e) applying the coating to the next panel in a second direction from the eve to the rib of the roof by reversing the direction of the applicator, without rotating the coating applicator;
- and,
- f) repeating the applying step and then the repositioning steps until reaching the second end of the rib having applied coating to all panels of the first area.
