The Norton 16" Red Heat Screen 120 Grit is a professional-grade sanding screen designed for hardwood floor refinishing, intercoat abrasion, and screen-and-recoat applications. It features 100% patented SG (Seeded Gel) ceramic alumina abrasive grain, delivering a fast, consistent cut with a fine scratch pattern that enhances finish adhesion while minimizing swirl marks and haze. These screens are ideal for use between coats of water- or oil-based finishes and are especially effective on engineered wood, exotic hardwoods, and high-traffic commercial surfaces like gym floors. The open mesh design resists clogging and loading, while the F-weight backing provides flexibility and shock absorption for smooth performance on uneven surfaces.
