Abstract:
A method of applying a spray-applied foam substance coating upon a structural surface, comprising the steps ofcontinuously applying said foam substance in liquid form in adjacent axially extending bands of said foam substance to form a coating of a resultant solid layer of said substance, upon said structural surface, from a spray applicator source moving in alternate directions along a track having a straight, horizontal portion and respective arcuate uphill opposite end portions, said spray applicator source moving transverse to an axially extending direction of each band of said bands of said substance, each said band having a predetermined width and axially extending length,said spray applicator source moving laterally in a horizontal plane parallel to said structural surface, said nozzle being moved in a vertical plane away from said lateral horizontal plane parallel to said structural surface,subjecting said spray applicator source of said substance in liquid form to an arcuate uphill movement upon said respective arcuate, uphill opposite end portions of said track at each end portion of each said transverse movement of said spray applicator source of said substance in liquid form, wherein said transverse movement of said spray applicator source of said substance in liquid form accelerates in speed, alone said track,moving said spray application source of substance along said respective arcuate, uphill opposite end portion of said track in liquid form outward as said spray applicator source of said substance in liquid form moves arcuately uphill, and tilts, thereby reducing the amount of said substance in liquid form being applied to said respective edge portions of each said band of said substance upon the structural surface at an end of each pass of said spray applicator source across each said linearly extending band of said substance.
