Abstract: A system and method for blasting an overhead surface is disclosed herein. The blaster system can comprise a first enclosure, a second enclosure, a pair of recirculators, a pair of loader valves, and a pair of propeller assemblies. The first enclosure can comprise a pair of primary ports, and a pair of control cages. The pair of primary ports can be at the front surface of the first enclosure. The primary ports can receive abrasive material. The pair of control cages can be attached at the bottom surface of the first enclosure forming a pair of curved surfaces, and a plurality of gaps. Each of the curved surface can comprise a slot. Each end of the slot can rest within each of the gaps such that the abrasive material received within the first enclosure can collect within the gaps and falls into the slot.
