Patent ID: 7314186

Claim:
A method of applying a chemical material to a surface, comprising: providing a wheel mounted spraying assembly; the wheel mounted spraying assembly comprising: a rod having an upper end portion and a lower end portion; a wheel rotatably mounted on the lower end portion of the rod for supporting the spraying assembly on a generally horizontal surface and enabling the spraying assembly to be moved over the generally horizontal surface; a spray nozzle mounted on the spraying assembly adjacent the wheel for spraying a chemical material in an expanding pattern for application to an application surface; the spray nozzle being oriented to spray a chemical material in a generally outward direction to one side of the lower portion of the spraying assembly and apply the chemical material onto a generally vertical surface extending upward from the generally horizontal surface over which the spraying assembly is being moved and to a portion of the generally horizontal surface over which the spraying assembly is being moved that is located intermediate the spray nozzle and the generally vertical surface; supply line means for supplying a chemical material under pressure to the spray nozzle; and control means for controlling flow of a chemical material to and through the spray nozzle; and using the spraying assembly to apply a chemical material to an application surface that is a generally vertical surface extending upward from the generally horizontal surface over which the spraying assembly is being moved and a portion of the generally horizontal surface over which the spraying assembly is being moved that is located intermediate the spray nozzle and the generally vertical surface wherein the chemical material is applied in a band having a uniform or substantially uniform width.
