Mixing mortar might not be the most exciting activity, but it's essential to do it quickly and do it right for a successful construction project.
Pump and sprayer maker Graco Inc. has introduced its ToughTek CM20 continuous mixer to make the job more portable, consistent and economical when contractors are using pre-blended bags of stucco or mortar mix.
Construction workers building the new Golden State Warriors arena in San Francisco gave the new product a whirl last week, with success, Graco said.
The new machine, with a list price of about $6,400, saves contractors time because it continuously mixes in the right ratio of water, regardless of how many bags are used.
The idea is a change from traditional mortar mixing, which requires material suppliers to deliver four different ingredients to a job site so skilled contractors can mix the ingredients on site to create individual batches, often by hand.
More material suppliers are beginning to pre-mix their own mortar and stucco blends and sell them in 80-pound bags. That means contractors just have to add water.
Sensing the trend, Minneapolis-based Graco designed its machine to be portable, lightweight and yet hold and continuously mix three 80-pound bags at once.
"We wanted to get ahead of the market," said Graco's ToughTek product line manager Bryce Gapinski. "We saw that it's trending the way of pre-blends," so Graco developed a continuous mixer that could handle multiple bags of pre-blended stucco requiring just the right ratio of water.
