Application Instructions
Prior to use of product follow instructions for use and
recommended safety precautions
Required material
■■ Adequate airless spray pump with hose and spray gun.
Pump must have minimum fluid pressure of 2,500 psi and
Volume transport of > 0.8 gal/min.
■■ High pressure hoses, rated to match pump capacity, with
minimum inner diameter of 3/8". Maximum hose length of
150 ft should not be exceeded
■■ Appropriate spray gun and tips. A contractor grade spray
gun capable of handing 2,500 psi fluid pressure should be
used. Recommended tip sizes are .221, .223, .321, .323,
.325, .421, .423, .425, .519, .521, .523, .619, .621 and .623
■■ Appropriate Steel members to be fire proofed (Note that
steel members must have been primed minimum 24 hours
prior to conducting this application walk through).
■■ Hilti Fire Protection Steel Spray. Check freeze tag on Hilti Spray.
■■ 1/2" cam action or impact drill
■■ Shielded mixer
■■ Empty bucket
■■ Wet film thickness gauge
■■ Dry film thickness gauge
Application conditions
■■ Confirm that ambient temperature meets required
application range. Lower temperatures increase curing time
and reduce spray ability. Higher temperatures cause fast
drying time and overspray. Hilti Fire Protection Steel Spray
should only be applied when the ambient air temperature
is between 50°F (10°C) and 104°F (40°C). The minimum
temperature must be maintained for a minimum of 24 hours
after application. Contractors may provide enclosure and
heat to maintain proper temperature levels.
■■ For optimum performance humidity levels should be below
75%. If the relative humidity exceeds 75%, precautions
should be taken to avoid condensation from forming on
the steel during application. Adequate ventilation must be
provided and maintained during application and curing
process to ensure proper drying.
■■ Confirm approved primer was used. A list of approved
primers can be sourced with the Hilti Technical Services team.
■■ Measure and document the primer thickness utilizing
the dry film thickness gauge. Utilizing the DFT gauge is
simple, simply place it against the surface and read the
measurement on the screen.
■■ Ensure no obstructions are in the way of the application
area, guaranteeing a minimum of two feet clearance to
allow proper spraying.
■■ Check steel members for intact, cured and proper primer.
Clean from grease, dirt, dust and mill scale
Spray pump safety precautions
■■ Always wear proper safety gear
■■ When not in use, safety lock should be engaged at all times
■■ Never use the spray pump with the front safety housing
removed
■■ When servicing the tip housing, always hold the spray gun
with the fingers behind the trigger
■■ Never point spray gun towards others
■■ Never place spray gun against any body part.
■■ When not in use, always release pump pressure
■■ Make sure all filters have been removed from pump and all
connections are tight on hose and spray gun
Set up instructions
■■ The instructions below will provide you a step by step
guide to set up the Spray in the pump and start spraying.
1. Open Spray pail and remove the plastic liner.

to three quarters until only Hilti Spray starts flowing from
the spray gun.
7. Turn the pressure down and stop the flow.
8. Move spray gun from the spare bucket to Hilti Steel
Spray pail, circulating material at a lower pressure for
approximately 30 seconds.
9. Install desire spray tip into safety housing and Install
safety housing on spray gun.
10. Turn pump pressure all the way up or to the desired
pressure setting and do a test spot on a scrap
cardboard to check for proper fan and desired pressure.
