Abstract
A method for coating surfaces with organic film-forming compositions, which may contain pigments or coloring matter, characterized by applying the composition to a surface or substrate while subjecting the surface or substrate to a gaseous environment whose temperature is above the boiling point of the vaporizable solvent vehicle(s) of the coating composition and removing the solvent vehicle from the applied coating in a controlled manner while in said gaseous environment. The temperatures of the environment, the surface and the coating composition are selected relative one to the other such that the film of coating will gel yet not "skin over" until the solvent vehicle has been substantially completely removed from the coating, the solvent vehicle will not be substantially lost from the coating composition until the coating has been applied to the surface, or substrate, and the application of the coating to the surface or substrate will not materially cool the surface or the environment.
