Blueline 3" Corner Finishers are designed to wipe down and feather both sides of an angle in one pass. It is used to follow the Corner Roller and wipe down excess compound left when the tape is embedded into the corner. The spring action compensates for corners that are slightly over or under 90 degrees and the blade design produces smoothly feathered angles.
Snap the Corner Finisher onto the ball-end handle and use it as a plow, with the nose end leading. Work from the bottom to the top of vertical angles and from one end to the other on ceiling angles. Detail corner and ceiling angle intersections with a drywall knife.
After the tape coat has dried, the Corner Finisher should also be used in conjunction with the Corner Applicator to apply the finish coat over the angles.
Snap the Corner Finisher onto the Corner Applicator and fill the applicator with joint compound. With the nose end of the Corner Finisher leading, start on the bottom of the vertical angle and apply pressure to the Corner Applicator, to start the flow of compound, while moving the tool along the angle. About 3 feet from the floor, release the pressure on the Corner Applicator and sweep it away from the angle. Then, starting at the top of the angle, pull the tool down the angle and release the pressure when you reach the compound left on the previous pass. Now sweep the Corner Applicator and Corner Finisher away from the angle. Ceiling angles are finished using the same methods.
Maintenance
Clean thoroughly, after every use, with a brush and water (or a water hose) to remove all joint compound from the tool. Then, after the tool is clean, lightly oil.
