An airless sprayer adapted to spray both paint and texture material. The sprayer uses a reciprocating piston that mechanically forces the material to be dispensed out of a charging chamber. The piston is driven by a motor mounted within a motor chamber. A working surface of the piston has a surface area adapted to dispense texture material. The sprayer is gravity fed with an overhead hopper. The sprayer is provided with a detachable overflow member that defines an overflow chamber for capturing texture material that leaks around the piston. This overflow chamber is configured relative to the motor chamber such that material leakage is contained within the overflow chamber and does not reach the motor chamber.

[ What is claimed is:] [19.] A system for applying coating materials to a surface to be coated, comprising:a main housing assembly defining a charging chamber into which texture material is introduced, a spring chamber, a motor chamber, an outlet chamber, and an outlet opening;a piston having a head portion defining a working surface and a tail portion, the piston head portion being disposed partly within the charging chamber and partly within the spring chamber and the piston tail portion being disposed within the spring chamber; anda motor assembly disposed within the motor chamber for causing the piston to reciprocate between a charge position and an expel position; andan overflow housing member attached to the main housing assembly such that texture material leaking from the charging chamber into the spring chamber flows into an overflow chamber defined at least in part by the overflow housing member; anda hopper member defining a hopper chamber, the hopper member being detachably attached to the main housing assembly such that texture material within the hopper member is gravity fed from the hopper chamber into the charge chamber.
