AI/ASSEMBLY, INSTALLATION
SURFACE PREPARATION
Dependent upon surface condition and intended service. Typical examples are as follows:
Grease and Oils - Solvent clean to SSPC-SP1-63.
Rust scale - Power tool clean to SSPC-SP11-87.
Mill scale-Sandblast to SSPC-SP6-63 (commercial).
Water immersion - (100ºF Maximum)
Sandblast to SSPC-SP10-63T (near-white).
APPLICATION
SPRAY (low-pressure compressor type)
Atomized air pressure - 50 lbs. Fluid pressure 15-20 lbs.
Orifice of tip -80/100ths. (.080).
Viscosity reduction - 4 parts Z.R.C. to 1 part XXX Thinner* or 16 parts Z.R.C. to 1 part
Xylol/Xylene.
SPRAY (airless type)
Pump - 30:1
Hose - 1/2" (I.D.) Airless type
Orifice of tip - 60 -26/1000ths. (.026).
Type of tip - Tungsten carbide, reversing (self-cleaning).
Filter screens - Complete removal is recommended. However, if screens are employed, use no
less than 30 mesh.
Viscosity - No reduction required.
Recommended procedure - Connect hose directly to pump, without filter assembly, ensuring a
hose length of 50 ft. maximum. Use least pressure possible. Start at 1500 lbs. and
increase as required for good spraying properties.
BRUSH OR ROLLER
Apply as received in container.
CLEAN-UP
XXX Thinner* or Xylol/Xylene.
*XXX Thinner is our special solvent.
