Abstract
An air powered sprayer for dispensing material slurries such as stucco or texturing on substrate such as drywall. The sprayer includes a canister assembly within which a piston assembly is adapted to reside and reciprocate along the length of the canister. An air inlet is disposed at one end of the piston canister assembly, and at an opposite end, a slurry inlet and outlet device is provided. Upstream from the slurry outlet there is a nozzle assembly which allows the through passage of the slurry material for subsequent combination with air at a nozzle assembly for broadcasting on the surface to be treated.
