The Norton 16" Screen 220 Grit (Red Heat) is a high-performance sanding screen designed for fine grit sanding on hardwood floors, concrete, and other tough surfaces. It features 100% patented Seeded Gel (SG) ceramic alumina abrasive grain, which delivers a cool, consistent cut, longer lifespan (2–3 times that of silicon carbide screens), and a finer scratch pattern to enhance finish adhesion and reduce swirl marks. These screens are ideal for final cut prep, between-coat abrasion, and screen-and-recoat applications, especially on engineered wood, softwoods, and high-traffic commercial or sports floors. The open mesh design resists clogging, while the F-weight screen backing provides flexibility and shock absorption for consistent performance on uneven surfaces.
