TapeTech© Corner Flushers make quick work of wiping or finishing inside corners. Direct flushers are used to apply joint compound to internal corners. Indirect flushers simply smooth compound that has been applied by another tool. TapeTech flushers work as both a direct and indirect flusher. That means you don’t have to decide which model to get, only which sizes fit your needs. The Corner Flushers fit all TapeTech© corner tools (Compound Tubes, 88TTF and HF handles, 35TT and 50TT Corner Applicators and 14TT MudRunner®).
