PRODUCT OPERATION, INSTRUCTION INFORMATION
The SharpShooter® 1 Drywall Hopper Gun, together with an air compressor, will apply most any sprayable
material that can feed by gravity through the hopper and that can fit through one of the holes in the orifice plate.
The texture that results can be adjusted in four ways.
1) Material Consistency
Follow the material manufacturer's recommendations for mixing. It is important that the material be thoroughly
mixed and be just thin enough to feed through the hopper. This enables the droplets of spray to stay on the wall/
ceiling surface and form a good texture. Do not thin the mixture to achieve a finer texture, rather increase the air
flow and select a smaller orifice.
2) Orifice Size
The circular orifice plate (2) on the front of the gun provides seven different orifice sizes. Larger orifice openings
will produce a coarser pattern than will a smaller opening. To change the orifice, loosen the two knurled nuts
(3,4). Pull the trigger back and rotate the orifice plate to the desired size. As you release the trigger the orifice is
centered. Finally, secure the orifice plate in position by first tightening the upper knurled nut and then the lower
knurled nut.
3) Air Flow
The air flow at the gun is adjusted by the ball valve-air line coupler (15). A reduced air flow will produce a coarser
texture; a greater air flow will produce a finer texture. The higher the air pressure, the finer the pattern; the lower
the air pressure, the coarser the pattern. If the air flow is too great, however, the grains within the mixture can
separate from the mixture and rebound off the walls. This can lead 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. Generally the distance between the air nozzle (25) and the mixture nozzle (5) should be
slightly greater than the size of the selected orifice. When the desired texture is achieved, the trigger position
can be set by tightening the wing-nut (16). This will ensure the needle is pulled back the same distance each time
so that the texture remains consistent. Releasing the trigger stops the material flow.
It is recommended that you set your pattern on scrap sheetrock or cardboard before spraying your finished
product. By experimenting with the various adjustments you should be able to obtain your desired texture. Note
the compound consistency, orifice, air pressure at the compressor, relative ball valve position, and trigger setting
for future reference.
