Limitations: Apply in good weather when air and
surface temperature are between 50º-125ºF and surface
temperature is at least 5ºF above the dew point. For
optimum application properties, material should be between
70 to 100ºF prior to mixing and application.
Maintain unmixed material in closed containers in protected
storage at 40 - 100ºF.
Surface Preparation: Good surface preparation is
essential to a satisfactory coating system. Surfaces to
be coated should be clean, cool and dry. Abrasive
blasting is recommended for best performance. Proper
blasting media shall be used to produce an average
profile depth of 1.0 mils minimum. Do not reuse abrasive
media. Remove blasting dust and grit from surfaces
before painting. Blasted surfaces should be coated
within 8 hours after blasting to prevent contamination of
New or Unfinished Surfaces - Ferrous Metal: "Near-
White Blast Cleaning" (SSPC-SP10) is recommended
for best performance. "Commercial Blast Cleaning"
(SSPC-SP6) should be considered minimum for exterior
Mixing: This is a one component coating. Always mix
thoroughly with a power agitator before application.
Cleanup: Clean all equipment immediately after use
with Thinner HJ-75 or Xylene. Completely
flush all spray equipment with either of these solvents.
Occasional flushing of spray equipment during the course
of the working day helps prevent buildup and possible
