Abstract

Many industries such as construction and aerospace industries use high build coatings for vari-ous 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 pro-vides a motive force created by a vacuum for delivering a dry material to the nozzle of the apparatus, the con-veyance device including an array of bores for sepa-rating the dry material to provide substantially uni-form wetting of the dry material when the dry material enters the nozzle. The conveyance device is particu-larly useful in applying plaster and stucco. The pre-sent apparatus eliminates concerns of pot-life, waste and product uniformity by wetting the dry material close to the nozzle outlet.
