Abstract: A method for producing a smoothed layer of cellulose material on a substrate, including, at least in certain aspects, mixing cellulose material with an adhesive and gelling material in aqueous solution producing a mixture, applying the mixture to a surface of the substrate, the mixture as applied having an outer surface, and smoothing the outer surface with a finishing tool, the finishing tool having a base, optionally a cushion portion adjacent the base, and a smooth non-permeable covering over the base, the smooth non-permeable covering for contacting, pressing against, and moving on the outer surface of the mixture as applied; and such finishing tools for use in such methods.
