[TowerTalk] Re: Galv. Paint for Towers

[Jonathan Starr]

The American Association of Hot Dip Galvanizers recommends zinc dust in
an epoxy base primer, which doesn't need a topcoat if you like matte
dark grey.

We use a 2 part product (the dust is separate from the epoxy) from Enron
that works great. Contrary to the spec sheet, you can mix it in small
batches if you fractionalize the two parts.

It is set off by humidity, so the drying time varies depending on
climate. When it starts to thicken, we add a bit of MEK thinner to
extend the pot life a bit.
