FUNTECK Pressure Washer Sandblasting Attachment, 1/4 Inch Quick Connect 5000 PSI, Including M22 Coupler Adapter. So far this has worked pretty good. Be sure to keep your sand or media covered so it doesn't get wet, or it won't be sucked up into the blaster nozzle. It worked great on a section of my sidewalk that was discolored. #Viralix #funteck #Ben
