The Graco M680™ Mortar Pump handles abrasive materials such as epoxy
mortars, non-skid coatings or cementitious materials, and tackles difficult
polymers with fillers such as glass flake, silica or sand.

Profitable shortcut to hand troweling

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

Less material waste and improved quality

With Graco’s M680 Mortar Pump, your crews can get more thickness control
by spraying instead of hand applying. The surface gets a more consistent
layer of material. In addition, there’s much less chance of material curing
before it gets applied.

* Some materials require special handling and testing;
contact Graco or your distributor for assistance

Fast, easy cleaning

The sprayer’s high velocity flush is often all that is needed to clean the
pump and prevent buildup of heavy material in the spray lines. If needed,
the pump is designed to be quickly taken apart for hand cleaning.

Built tough for long-lasting durability

Engineered to withstand the grittiest materials, the Graco M680 pumps
heavy materials at low pressures (typically 200 to 500 psi/13.7 to 34.5 bar)
and uses an applicator to atomize the material and transfer it to the substrate.
Its low-pressure design reduces wear and tear on the pump lower.

Ideal for coating contractors

Your crew will discover that the Graco M680 Mortar Pump is easy to use,
with similar functionality to an air-operated sprayer. They’ll be up and
running in no time.
