For the best results, the operator must become thoroughly familiar with the operation of the Mason Texture Gun. The patented nozzle adjusts “in” (clockwise) for heavier textures; and “out” (counter clockwise) for lighter textures. The pumping action should be smooth and even. Short, powerful strokes are not necessary and will produce inconsistencies in the pattern. We urge new owners to experiment with various gun adjustments to gain the expertise necessary for various texture patterns.
