Apart from casting materials, where suitable shuttering is required, Gouda Refractories also provides gunning mixes for direct placement on a wall or roof. The dry particulate material is conveyed pneumatically through a hose and water is added at the nozzle. The gunned sections typically are equipped with anchors in order to keep the castable in place. Gouda Refractories gunning mixes are characterized by a low rebound loss and minimal dust development.
