Description

Polyethylene-Drum Mortar Mixer

Lightweight, Durable, and Built for Performance

The polyethylene-drum mortar mixer from Multiquip is designed for contractors who value easy maintenance, consistent results, and long service life. Unlike traditional steel models, the polyethylene drum resists dents, rust, and buildup, making cleanup faster and extending durability. Available in 7, 9, and 12 cubic-foot capacities, the polyethylene-drum mortar mixer handles everything from residential masonry work to large-scale commercial projects, offering rugged reliability in a lightweight design.

Power Options to Match Your Needs

Multiquip provides both electric and gas-powered models to ensure flexibility across different environments:

  • Electric Models – Quiet and emission-free, these mixers are ideal for indoor projects or spaces where noise restrictions apply.
  • Gas Models – Outfitted with reliable Honda engines, they deliver strong torque and continuous performance on outdoor or remote sites.

By offering both choices, the polyethylene-drum mortar mixer adapts seamlessly to diverse jobsite demands.

Versatile Applications Across Trades

More than just a standard grout mixer, these machines excel in a variety of applications:

  • Mortar blending for brick, block, and stone work
  • Grout preparation for structural reinforcement and repair
  • Stucco and plaster mixing for professional finishing

With this versatility, every masonry mortar mixer or plaster mixer in the lineup becomes a valuable asset, supporting multiple trades with one dependable tool.

  • Polyethylene drum resists buildup, rust, and chipping
  • Towable frame with removable tongue for safe and easy transport
