The Norton 16" Screen 150 Grit (Red Heat) is a professional-grade sanding screen designed for hardwood floor refinishing. It features 100% patented SG (Seeded Gel) ceramic alumina grain, delivering a fast, consistent cut while minimizing the risk of burnishing wood. The open mesh design resists loading, effectively shedding dust and finish residue—ideal for screen-and-recoat jobs, intercoat abrasion, and final sanding.
