Multiquip Whiteman Steel-Drum Mortar Mixer: Built for the Toughest Mixing Demands

Industrial Strength for Professional Masonry

When quality and consistency matter, Multiquip Whiteman’s steel-drum mortar mixer lineup delivers. These rugged machines are built to handle the toughest mixing jobs in masonry, stucco, and plaster applications. Designed for contractors who need reliable performance day in and day out, the steel-drum construction offers unmatched durability and extended drum life, even under heavy loads.

With sizes ranging from 6.3 to 12 cubic feet, Whiteman mixers can handle a wide range of material volumes and mixing tasks, making them a go-to choice for professionals across the construction industry.

Your Choice: Electric or Gas Power

Multiquip understands jobsite flexibility is critical. That’s why their steel-drum mortar mixer is available in both electric and gas powered models:

  • Electric Models: Quiet, emission-free, and perfect for enclosed or noise-restricted environments. These mixers deliver consistent performance without sacrificing power, ideal for interior work or urban jobsites.
  • Gas Models: Featuring trusted Honda engines, these mixers provide the mobility and independence needed in outdoor or remote job locations. They’re ideal for rugged environments where electrical access may be limited or unavailable.

No matter the power source, each unit is designed for peak efficiency, giving contractors the flexibility to choose what suits their workflow best.

Mix More Than Mortar

These mixers do more than just mortar. They are designed to perform across a range of materials, making them extremely versatile:

  • As a masonry mortar mixer, it creates smooth, consistent batches ideal for block and brick work.
  • As a grout mixer, it handles thick mixes with ease for anchoring, filling joints, or reinforcing structures.
  • As a plaster mixer, it produces uniform results for interior or exterior plaster finishes.

This multi-functionality ensures every mix is done right, no matter the material.

Key Features That Stand Out

  • Heavy-Duty Steel Drum: Built for long-term use and optimal mixing performance
  • Towable Frame: Easy transport with reinforced tow bars and balanced design
  • Hydraulic and Manual Dump Options: Depending on the model, allows for safe, efficient material discharge
  • Replaceable Rubber Blades: Ensure thorough mixing and easier cleanup
  • Easy Maintenance Access: Reduce downtime and extend machine life

For professionals demanding high performance and versatility, the Multiquip Whiteman steel-drum mortar mixer stands out as an essential jobsite asset. With options tailored for both indoor and outdoor use, and the capability to serve as a masonry mortar mixer, grout mixer, or plaster mixer, it offers the reliability and power to keep projects moving forward.

Whether you choose electric or gas, you’re investing in a mixer that meets the industry’s highest standards. Ready to get mixing? Choose Multiquip Whiteman steel-drum mortar mixer.
