What is Traditional Hand Spray?
Traditional Hand Spray is a time-tested method. Used for decades in GRC production, it’s the most versatile and popular production technique and the one most often chosen by new start-ups.
Through a specially designed spray gun – such as the Concentric Spray Gun – manufacturers simultaneously spray chopped AR Glass Fibres and cementitious slurry onto a mould, efficiently distributing fibre throughout the mix. This process is followed by hand compaction using a Spring Roller to ensure maximum flexural strength is achieved.
This method is known for achieving the highest strength levels, attributable to its high content of AR Glass Fibre (4-5% by weight), elongated fibre lengths and planar fibre orientation.
