Section 2 - Stripe Hog Systems
Spray bar selection is determined by requirements
of the removal application being performed. The
width of the spray bar selected is critical. When
removing paint lines, it should be sized to the
width of the line whenever possible. In most situ-
ations, the spray bar selected should be 2” wider
than the width of the line to reduce the potential
for damage and increase productivity by concen-
trating the blasting pressure over the painted line.
The following should be considered when
selecting a spray bar:
• The size of the line marking. The spray bar
should be 2” wider than the marking.
• The type of marking being removed. (Paint,
thermal or rubber)
• The thickness of the material being removed.
• The type of road surface. (Concrete or asphalt)
• Profile requirements per job specifications.
Hog Technologies offers a variety of spray bar and
blasting head configurations to meet requirements
of all types of removal projects. Examples of avail -
able spray bar configurations are included in the
Waterblasting Operation section of this manual.
You can also contact our customer support depart-
ment for assistance in selecting the correct spray
bar and/or nozzle configuration for your project
at (877) HOG-ROAD.
Refer to the Maintenance section of this manual
for instructions to install or replace spray bars
and nozzles.
