Using a pneumatic hose to spray concrete materials onto a receiving surface, both the wet mix and dry mix methods are used in construction projects all over the world. The primary distinction between the two methods is that the wet mix approach uses ready mix concrete while the dry mix approach introduces water at the nozzle to complete the mixing process.
