Still mixing with a drill motor and a paddle? If you are mixing more than 3 bags an hour, then you need to step up to a versatile IMER Mix 60 Plus Electric Mortar, Grout, and Plaster Mixer and mix a full bag of material in low-speed rotation. Most drills are meant to spin fast, which creates a mudslinging, wall-splattering experience. The Mix 60 Plus can solve your problems by adding your 50-60 lbs of stucco, thinset, epoxy, etc. in a controlled and easy method. The top splash-guard allows you to add water and more material as the paddles are spinning without missing a second of mixing action. Walk away from the mixer "prep" your next batch since this unit is hands-free, then come back and repeat the process. Stop paying a laborer to be a drill stand and get them working on other things. An optional self-leveling paddle is available to mix your underlayment materials two bags at a time!
