Abstract: A device for impressing a pattern or design into uncured concrete having a hollow cylindrical sleeve which can be paired with a conventional paint roller with a roller applicator sleeve having a nap. The hollow cylindrical sleeve includes an inner tubular surface which includes a inner surface texture to engage the nap of the conventional paint roller and an outer surface which includes a negative relief for imprinting a texture and/or a design in uncured concrete to create an appearance of a variety of materials such as, but not limited to, brick pavers, stone, rock, and hardwood.

Abstract: This invention relates to an apparatus for simulating the appearance of individually laid materials, such as bricks or cobblestones, in a curved pattern in a concrete surface. The apparatus includes a flexible spine with a plurality of ribs extending from a surface of the flexible spine. The apparatus further includes a texture mat for imprinting a pattern, for example a brick surface, a stone surface or a wood grain surface, into the concrete surface. This invention also relates to a method of using of the apparatus for simulating the appearance of individually laid materials in the concrete surface.
