Abstract
A roller cover and associated pair of cams attachable to opposite ends of the roller cover. Each of the cams has an outer diameter extending radially outwardly beyond an outer diameter of the roller cover a predetermined distance for maintaining the outer diameter of the roller cover a corresponding distance from the surface being coated during rotational movement of the roller cover over the surface to act as a thickness gauge for the coating being applied to the surface.
Claims15
A spreadable coating applicator comprising a roller cover and a pair of cams that act as a thickness gauge when the roller cover is used to apply a spreadable coating to various surfaces, the roller cover including a hollow core externally surrounded by an outer covering that is bonded to the hollow core, the outer covering forming a radially outermost surface of the roller cover defining an outer diameter of the roller cover, wherein the radially outermost surface is configured for transferring a spreadable coating onto an external surface, and the pair of cams being attached to opposite ends of the roller cover, each of the cams having an outer diameter extending radially outwardly beyond an outer diameter of the outer covering a predetermined distance for maintaining the outer diameter of the outer covering a corresponding distance from the surface being coated during rotational movement of the roller cover over the surface to act as a thickness gauge for the coating being applied to the surface, and wherein the outer diameter of the pair of cams forms a radially outermost surface of the spreadable coating applicator.
