The TapeTech MudRunner® ensures precise control and minimal effort when delivering joint compound to corners. A straightforward twist of the wrist initiates the piston, maintaining a consistent flow of joint compound, and a simple twist in the opposite direction instantly halts the flow.
It can be paired with TapeTech Corner Finishers for swiftly achieving high-quality finished internal corners, or with Mud Heads for applying compound to both internal and external corners during the installation of paper-faced corner bead on drywall.
The MudRunner® has the capacity to hold 50% more joint compound than a standard 8″ Corner Applicator and 70% more than a 7″ Corner Applicator.
