To adjust the texture when using the MARSHALLTOWN WS1728 Sharpshooter 2.1 Drywall Hopper Gun, you can follow these steps:

1. Material Consistency: Follow the material manufacturers' recommendations for mixing. The material should be thoroughly mixed and just thin enough to feed through the hopper. This will ensure that the droplets of spray stay on the wall/ceiling surface and form a good texture. Do not thin the mixture to achieve a finer texture; instead, increase the air flow and select a smaller orifice.

2. Orifice Size: The circular orifice plate on the front of the gun provides seven different orifice sizes. A smaller orifice will result in a finer pattern, while a larger orifice will result in a more coarse pattern. To change the orifice, loosen the center xxxx , pull the trigger back, and rotate the orifice plate to the desired size. Finally, secure the orifice plate in position by tightening the knurled nut.

3. Air Flow: For spraying most materials, a continuous air supply of at least 7 CFM at 25 psi is required. The air flow at the gun is adjusted by the ball valve-air line coupler. A reduced air flow will produce a coarser texture, while a greater air flow will produce a finer texture. However, if the air flow is too great, the grains within the mixture can separate and rebound off the walls, leading to waste and mess.

4. Trigger Setting: The position of the trigger controls the amount of material flow. As the trigger is pulled back, more material is allowed to feed through. The distance between the air nozzle and the mixture nozzle should be slightly greater than the size of the selected orifice for a more consistent texture. Adjust the adjustment xxxx to the desired depth to ensure the needle is pulled back the same distance each time, resulting in a consistent texture. The trigger lock can be used for reduced fatigue on larger projects, and releasing the trigger stops the material flow.

It is recommended to set your desired texture on scrap sheetrock or cardboard before spraying your finished product. By experimenting with the various adjustments, you should be able to obtain the texture you desire.
