To apply popcorn: ceiling texture, use one
of the largest openings (#1, 2, or 3) - Which
one will depend on the size of the acoustic
aggregate. The trigger setting should be fully
open. The air pressure should be 20–25 psi.
NOTE: The textures described above are
made using either a 3/8" or 1/2" I.D. hose. If
you are using a 1/4" I.D. hose, use greater
air pressures than specified.
