Corner Applicators are designed to work in tandem with Corner Finishers/Angle Heads. Together, these tools allow a user to consistly apply a light finish coat to both sides of an angle at the same time. Fill the Corner Applicator with the Loading Pump and Filler Adapter. Snap a Corner Finisher on the tip of the Stainless Steel Cone. The Corner Applicator is pressure controlled, meaning the harder you push, the more mud/compound is applied. We suggest applying even pressure throughout the complete application.
