TapeTech Corner Applicator MudRunner

The TapeTech MudRunner® holds 50% more joint compound than a standard 8" Corner Applicator and 70% more than a 7" Corner Applicator. Corners can be precisely controlled and joint compounds can be delivered with minimal effort. The piston is activated by a simple twist of the wrist, which creates a consistent flow of joint compound. The flow stops immediately when you twist it back.

It can be used in conjunction with TapeTech Corner Finishers to quickly achieve high-quality, finished internal corners or with Mud Heads to apply compound to internal and external corners when installing paper-faced corner beads.
