What is premix, premix spray and simultaneous spray?
Premix is the process of adding pre-chopped fibers into the wet cement/sand mix at the end of the mixing cycle. This mix can then be cast, like concrete, or sprayed [spray premix] through Spray-Techs specially developed equipment. Simultaneous spray uses continuous strand fibers which are fed into a hand held chopping gun. This strand is cut and sprayed out at the same time as a second gun sprays out the wet mortar. Each process has its own advantages and disadvantages and these will be explained by Spray-Tech.
