Concrete Texture rollers for concrete textures on floors, walls, water walls, water features, driveways, patios, trim work and more. All rollers are 9 1/2" x 3 1/2" and fit a regular size paint roller handle (handle not included). With Each roller comes a water retaining sleeve that fits over the roller. This water retaining sleeve is used instead of using mineral spirits or other chemicals, just place the sleeve over the roller, dip the roller in water and it becomes non-stick without losing the texture created from the roller.  Stamps are used over any freshly applied Masonry Mortar trowelled upon a wall or surface at ¼” to ½” thick. Dimensions: 12"x12" Round Stamp. Spray surface and stamp with odorless mineral spirits prior to stamping. Great for texturing artificial boulder scapes, table tops, and counter tops.
