30 SURFACE PREP 2018 COATINGSPROMAG.COM the grit, we were able to profile the exposed aggregate stones, essentially cleaning and profiling at the same time," explained Cook. On this project, that 100 percent crystalline silica-free glass aggregate was Enviro-Grit by United Concrete & Gravel Ltd. And it was made from locally recycled glass! "It was kind of a tie in — an interesting tie in because we were using crushed glass to clean the floor, and that's exactly what they do. A portion of their bottles are crushed and used for other products," Cook said. Lots of combos on this job! Backward Is Forward According to Cook, the facility did a light pressure washing of the area before the Geo-Blast duo arrived on site. But it was up to the experts to get the surface ready for the coatings. "W hat you' ll typically do is work closest to the drain first," Cook explained. "at way, you're not putting anything that you're trying to remove back onto the surface where you're going to be working next." From the drain, they worked their way backward. Wearing full-face respirators with organic cartridges from Sperian by Honeywell Safety Products, they started with blasting with the glass aggregate to properly clean and profile the concrete. Other personal protective equipment (PPE) included protective suits, gloves, and steel-toed boots. en, they circled back and used the washdown mode, which was completed using the same blasting equipment. e goal during washdown was to remove the spent media and any other remaining debris so that they could "see what we've done prior and also get the desired results in a more Facility Floors Geo-Blast's work would start near the drain and work backwards to remove any substances, such as the labels and tabs from the bottles and cans, out of the work space. The crew wore proper personal protective equipment (PPE) during the job. That included full-face respirators with organic cartridges from Sperian by Honeywell Safety Products, protective suits, gloves, and steel-toed boots. Since the facility was already used for glass and water, Geo-Blast didn't worry about contaminating with more glass and water. As much of the spent abrasives as possible was removed with shovels and brooms. Once the floor was blasted, Geo-Blast used the same equipment to wash everything down. This cleaned the concrete from any contaminates and profiled the concrete for the coatings to come later.
