What is Spray Premix?
As the name suggests, the Spray Premix method involves the spraying of premixed GRC. Prior to spray application, chopped AR Glass Fibre and a cementitious slurry are combined before being subsequently applied using a specially designed spray gun such as the MK5A.
Compared with Traditional Hand Spray, strengths attained through the Spray Premix method are generally lower, mainly due to the reduced AR Glass Fibre content (generally around 3% by weight), shorter fibre lengths and a multi-dimensional fibre orientation.
Although falling short in this respect, the Spray Premix approach stands out by delivering mechanical properties that are more consistent and, in some cases, superior to those attained through the Cast Premix method. Moreover, this technique ensures uniform distribution of fibres throughout the mix, resulting in GRC products that exhibit exceptional integrity and strength.
By combining the advantages of both Traditional Hand Spray and Cast Premix methods, Spray Premix is fast becoming the method of choice for producing a vast variety of smaller architectural items.
