GFRG Spray Equipment Systems

Unlike GFRC sprayers, our MaxG GRFG Sprayer allows you to adjust the set time to your needs due to our patented process

RimCraft Max G2 Sprayer

RimCraft Max G Sprayer

RimCraft's Max G Spray System is a full size machine for High Output GFRG spray-up operations. It is available with a 2 or 3 section extended reach boom with a 10 Ft and up to an 18 Ft radius.

The 3 piece boom (max C3) unit is built on a larger, more stable base for the extra length. This system is designed for use with either Premix or Chopped Fiber spray

With no-flat 14” tires in the rear and large Urethane covered casters in the front, this unit can easily traverse rough factory floors.

RimCraft's patented process allows you to retard the Gypsum to give you longer working time while providing you a controllable set time by injecting the Accelerator at the gun. This process is fully explained here on our FAQ page
