Hi John,
When you use Tnemec, or probably any two part coating system, your
people will REALLY have to pay attention to the MSDS sheets and you will
need to insist on them wearing respirators with chemical cartridges,
even if the work is being done outdoors. This is not "paint" in the
regular sense of the word even though it is "painted" on, and workers
have to educate themselves about the stuff.
We painted lintels in a large courtyard on a sunny windy day, and the
vapors, which seem to be heavier than air, sickened people inside the
building. The next day we moved to the rooftop to avoid this problem and
still had reports of people inside the building complaining of the smell.
Also, your people will need to wear gloves, and eye protection. Clean up
is with MEK (Xylol) if I remember correctly and that stuff's not a walk
in the park either although people widely disregard its hazards.
The only other thing I would have to say is to put the Tnemec on in
thinner, rather than thicker coats even though it cures rather than
dries. On a lintel, you want self-levelling with the pits filled in, but
on an ornamental piece like a gate or balustrade, it is easy to lose
detail with it.
