Review on 🔨 3M 9090NA Medium Grit Drywall Sanding: Achieve Flawless Finish Effortlessly by James Small

These drywall sanding nets are very effective at both sanding and with enough airflow to keep dust strong to reduce when used with a drywall sander (I have a Hyde Tools 09170 Dust-Free Vacuum Drywall Sander). The reason for the 4 stars is that while the flat sanding surface will last a long time, the screens on the corners of the sanding pad tear/wear/rip a little more easily than I would like to see and this will lead to replacement long before the main grinding surface is worn. I've only used these backings for drywall, so the wear seems to just be from hitting the corners when sanding.
