Abstract: A dual roller stencil applicator for applying a stencil pattern to a surface. The applicator has a frame with a handle supporting first and second rollers, the first roller having a porous outer layer for receiving and holding paint and a second roller having a raised stencil design thereon, with the first and second rollers in alignment and movable with respect to each other. The second roller is mounted for selective displacement from the first roller such that when the first roller is to be loaded with paint, the second roller is not in contact with the first roller, and when the apparatus is in an operating condition, the first and second rollers are urged together, permitting the first roller to supply paint to the raised stencil of the second roller. The stencil roller is completely removable from the applicator for cleaning. A drive wheel assembly is coupled to the second roller to rotate the second roller when the second roller is urged against a surface to which a stencil pattern is to be applied.
