When I am taping ceilings with my Bazooka, mud is coming out on both sides of the tape and falling to the floor. Why is this happening?

When taping ceilings with the TapeTech Automatic Taper, use both drive wheels for the first 4” to 6” (101mm to 127mm) then engage the creaser wheel to secure the tape and tilt the bottom of the automatic taper at a slight angle, leaving only one drive wheel in contact with the drywall surface. Move the Taper (04TT or 05TT) along the drywall joint with the taper head leading the way as you tape the ceiling joints.

This method ensures the proper amount of joint compound is applied to the joint and that the tape adheres to it until you wipe it down with the taping knife.
