Dust particles as small as 10 microns (much smaller than the thickness of human hair) can cause visible blemishes in a painted surface resulting in costly reworks or a sub-standard paint finish. "Quality Finish" media is designed to prevent these blemish causing particles from entering the painting area. "Quality Finish" Ceiling Diffusion Media is offered in blankets and rolls for downdraft booths. "Quality Finish" panels have internal self support wires for use in cross-flow booths.
