The Seymour Midwest 18″ Spiked Roller with 1-1/2″ supersharp tines is designed for releasing trapped air and improving flow in thicker self-leveling coatings and overlays. The longer, precision tines penetrate deeper to break surface tension, helping eliminate bubbles and ensure a smooth, uniform finish. Built for durability and consistent performance, it’s ideal for epoxy, urethane, and cementitious applications.
