ABSTRACT:
A device for applying a substantially uniform thickness of a spreadable coating on a substantially planar surface has a handle, a roller attached to the handle, and a spacer on the outer peripheral surface of the roller for engaging the surface to be coated. The spacer defines an arc of at least about 360.degree. around the outer peripheral surface of the roller for maintaining the outer peripheral surface of the roller both in communication with and spaced from the surface to be coated at a distance corresponding to the radial thickness of the spacer means during travel of the roller over the surface to be coated. In one embodiment, the spacer is a filament helically wound about the outer peripheral surface of the roller. The filament is releasably mounted to the roller and has a substantially uniform radial thickness. Also disclosed are methods for making and using the device of this invention.
