LW Combination Spray Gun
For Traditional Hand Spray GRC, the LW Combination Spray Gun can be used as an alternative to the Concentric Spray Head; however, it’s mostly recommended for spraying Glassfibre Reinforced Gypsum and other fast-setting materials.
The gun consists of a glass fibre chopper and a slurry gun mounted on a single bracket. The angle of these two components can be varied to adjust the spray pattern. By just using the slurry gun, operators can also spray fine mist coats. Cementitious or gypsum slurry is supplied via a pump and flexible hose to the slurry gun where it is atomised by compressed air and projected as a ‘slurry cone’ through the nozzle. The glass fibre roving is cut to length within the chopper mechanism from which it is blown into and mixed with the slurry, forming a sprayed composite on the mould surface.
After spraying the GRC or GRG, the composite is consolidated by roller compaction. Since the slurry gun can be easily dismantled and cleaned, the LW Combination Spray Gun is ideal for spraying fast-setting materials. It is also useful when oversized (2-3mm) particles may be present in the sand as these will not block the slurry gun.
