A profitable shortcut to hand troweling

Hand troweling cementitious materials is time-consuming. Save time, speed up the process and increase your profits by using a Graco M680 Mortar Pump to spray and finish-trowel the material instead of using the traditional hawk and trowel method.

The Graco M680 Mortar Pump is engineered to withstand the grittiest of materials, yet is easy to use and clean. Its high velocity flush is often all you need to clean the pump and prevent build-up in the lines.
