Disclosed is a process for making emery boards comprising the steps of providing a substrate selected from the group consisting of wood, cardboard and plastic sheets having first and second surfaces; adhesively applying abrasive paper on at least one surface of said substrate; forming on said abrasive surface a uniform film comprising a lubricant and a humectant selected from the groups consisting of lubricant and humectant polyethylene glycols by applying a film of a solution comprising said lubricant and humectant on said surface and drying said surface, said film being sufficiently thin so as not to impart a greasy feeling to the touch on said emery board nor interfere with the abrasive action of said board; and cutting out emery boards from said surface in the desired shape.
