Abstract
Abstract A method of applying a material of particulate form to the surface of an object by using a liquid, wherein the liquid is applied to the surface of the object to provide a film of the liquid thereon, and then the material of particulate form is applied to the film of the liquid on the surface of the object. Excess liquid may be removed from the surface of the object by using a jet of air current before the material of particulate form is applied to the film of the liquid on the surface of the object.
