Abstract
Many industries such as construction and aerospace industries use high build coatings for various purposes. Spray system for applying high build coatings allow thick coating to be applied relatively quickly as opposed to manual methods. The present application provides for a spray system including a spray apparatus having a conveyance device which provides a motive force created by a vacuum for delivering a dry material to the nozzle of the apparatus, the conveyance device including an array of bores for separating the dry material to provide substantially uniform wetting of the dry material when the dry material enters the nozzle. The conveyance device is particularly useful in applying plaster and stucco. The present apparatus eliminates concerns of pot-life, waste and product uniformity by wetting the dry material close to the nozzle outlet.
