Abstract
An apparatus is disclosed which uses a high volume low pressure air curtain in an 'air chisel' to inhibit and reduce the bounceback and overspray of material sprayed on a work surface. The air chisel directs a lateral air curtain along each side of a plume of sprayed material parallel to the long axis of the plume and directed toward the contact of plume and work surface. An air chisel may be attached to a spray gun or may be mounted on a stand adjacent to the work surface. Any source of high volume low pressure air may serve to provide air to an air chisel.
