Abstract: A drywall mud texture sprayer. A pressurized air canister and a drywall mud canister are connected to a backpack that a user wears on his back. The user holds a spray gun in his hands. Pressurized air from the pressurized air canister provides pressure to both the spray gun and the drywall mud canister enabling the spray gun to spray the drywall mud. In a preferred embodiment, the drywall mud canister is a 1.0 gallon canister and the pressurized air canister is a ½ gallon, 5000 psi CO2 tank. The equipment (including the backpack, CO2 and drywall mud) all together weighs about 25 pounds so it can easily be carried by the average worker.
