A device is provided for applying and/or finishing viscous materials along at least one adjoining surface or a bead along a corner, while simultaneously effecting all of the surfaces substantially free of any excess of the viscous material. The device includes a reinforcing portion (24), at least one operative extension (34R), (34L) with a working edge (56R), (56L) that protrudes beyond the termination (out of view) of the reinforcing portion, and a forward working edge (36), (38). The viscous material is formed with the forward edge. The angle of the operative extension edge to the forward edge is variable and resilient, which conforms to irregularities of the corner and variations in the position of the reinforcing portion and the forward working edge in relation to the adjoining surface, while sidewardly force is maintained against the adjoining surface. A seal is produced and maintained between the extension edge and the adjoining surface. The seal continuously prevents the viscous material from oozing between the extension edge and the adjoining surface, whereby a uniform clearly defined junction of the smooth applied surface and the clean unscathed adjoining surface is easily and efficiently produced.

1. A device for spreading a viscous material on a surface, comprising:a substantially rigid and planar blade member having a substantially straight working edge at an end thereof, said blade member having at least one substantially straight side edge adjacent to and extending from said working edge and defining an oblique angle therebetween; at least one substantially planar flexible side flap integrally formed with and along said at least one side edge of said blade member and comprised of a resilient material; said at least one side flap is mounted to said blade member such that it is free to flex about an axis coincident with said at least one side edge, said at least one side flap having an increasing width along said side edge from adjacent said working edge to a portion spaced therefrom; and a handle mounted to a portion of said blade member; whereby said at least one side flap readily conforms to said surface, thus removing any excess material thereon. 2. The device of claim 1 wherein said oblique angle defined by said at least one side edge and said working edge is an acute angle.3. The device of claim 1 wherein said blade member having a thickness that tapers toward said working edge.4. The device of claim 1 wherein said at least one side flap having an increased thickness spaced from said working edge.5. The device of claim 1 wherein said at least one side flap having at least one peripheral lip protruding beyond at least one of it's major surfaces.6. The device of claim 1 wherein said at least one side edge and said working edge terminate at a rounded corner of said blade member.7. A device for working viscous materials along at least one surface comprising:a blade member having two generally opposed major surfaces and a working edge at an end thereof, the blade member having two side peripheries and each side periphery is located respectively at generally opposite portions of the blade member adjacent to and extending from the working edge; two resiliently flexible side flaps and each side flap having two generally opposed major surfaces, means integrally connecting one of the two side flaps with and along each side periphery of the blade member; and each of the two side flaps having a width projecting from and increasing along the side periphery from adjacent the working edge to a portion spaced therefrom, each side flap is mounted to the blade member such that it's increasing width is free to flex and bend increasingly inward from along it's outer periphery; whereby at least one of the two side flaps readily conforms to the at least one surface, thus removing any excess material thereon.
