A method and an industrial robotic device for uniformly applying coatings at appropriate thickness and pitch upon a surface moves a spray applicator foam dispenser between two parallel tracks. The uniform application of foam at each pass is assured, by accelerating the speed of the foam dispenser at the end of each pass, by providing respective curved uphill distal ends of the tracks, so that the spray applicator foam dispenser moves up the curved distal ends and returns quickly while changing speed tilt and direction at the end of each pass.

[ I claim:] [1.] A spray applicator for applying a roofing polyurethane foam coating upon a structural surface, such as a building roof or other terrestrial surfaces, comprising:a means for continuously applying said polyurethane in liquid form in adjacent extending bands of foam to form a resultant solid foam coating upon said roof, each band having a predetermined width and length, said means comprising a foam applicator source movable on a track continuously in alternate directions transverse to the width of each band of said bands of said foam;a means for subjecting said applicator source to an uphill movement, said means comprising said track being bent at respective end portions of each said transverse movement of said applicator source;said foam applicator source being titled outwardly by said track as said foam applicator source moves uphill on said track, thereby reducing the amount of said liquid foam being applied to respective edge portions of each said band of foam upon the roof at an end of each pass of said liquid foam applicator source across each said band of foam;said foam applicator source being a nozzle; and,a radially extending swinging arm with a telescoping slide mechanism providing said transverse movement of said foam applicator source along said track, so that said foam applicator source moves linearly, said swinging arm pivotable about a pivot fulcrum point.
