  • APPARATUS, COMPONENTS, METHODS AND SYSTEMS FOR USE IN SELECTIVELY TEXTURING CONCRETE SURFACES
    Publication number: 20200180109
    Abstract: Apparatuses, components, methods, and techniques for selectively texturing concrete surfaces are provided. An example method of providing a surface portion of an architectural precast concrete wall panel with an abraded texture is provided. The method includes a step of spraying a surface portion of an architectural precast concrete wall panel with an aqueous-based particulate abrasive mixture under conditions adequate to at least partially abrade the surface portion. An example sprayer system for abrading a concrete surface is also provided. The system includes an aqueous-based particulate abrasive mixture dispenser including a spray nozzle arrangement. The system also includes a material communication assembly in abrasive flow communication with the aqueous-based particulate abrasive mixture dispenser. The system also includes a dispenser positioning arrangement.
