MAI®4JOB-BUSINESS
The world’s most flexible plastering machine


The MAI®4JOB-BUSINESS ultra transportable plastering machine mixing pump
The MAI®4JOB-BUSINESS is a unique plastering machine for pre-mixed dry mortar that fits through almost every door, making it one of the most flexible and useful mortar mixing pumps on the market.
It can be disassembled into individual components in a very short time without tools, allowing it to be transported with ease. This also means that transporting the plastering machine over several floors on your construction site is no problem. This feature also proves our commitment to occupational health and safety, by reducing the risk of back problems from lifting heavy machinery.
Flexible performance in a plastering machine
Another level of flexibility is achieved by the fully automatic MAI®4JOB-BUSINESS mortar mixing pump thanks to the ability to load dry mortar material directly from a transport silo, a silo container, or manually from sacks. It can also be integrated with a pneumatic dry mortar conveying system.
The MAI®4JOB-BUSINESS mortar mixing pump is designed to process all kinds of factory-pre-mixed dry mortars (lime, cement and gypsum based) for both external renders and indoor plasters.
Innovative easy-clean design and theft protection
MAI® is extremely proud of the innovative Easy-Clean mixing tube on the MAI®4JOB-BUSINESS. The easy to clean mixing zone is made of highly wear-resistant MAI®CODUR synthetic and both the water system and control cabinet are removable. This latter feature is also an effective anti-theft measure on the building site.
A high quality, German-made, drive engine and diaphragm compressor come as standard, as is a water pump. The remainder of the plastering machine is built from hot-dip galvanised steel components, guaranteeing a long service life.
The MAI®4JOB-BUSINESS is a flexible plastering machine mixing pump that offers maximum operating convenience and total reliability. Talk to the experts in mortar mixing pumps today.
