Hey, I'm Alex with GME Supply.
You might look at a can of Cold Galv and just
think it's a can of silver paint, but it's
definitely not. We'll explain that, and a
few other topics in this video.
This is Cold Galv 101.
Cold Galvanizing compound is a single component
zinc coating used to protect bare steel from
rust and corrosion.
Although it's applied like paint, it is not.
It does give the same protection as hot dipped
galvanizing.
Cold galvanizing compound acts as an active
coupling to the bare steel parent metal, to
form an electrolytic bond. In the presence
of an electrolyte, AKA moisture, zinc dust
in the cold galv will sacrifice itself to
protect the steel.
The surface must be clean, dry steel. Use
a wire brush to remove any of the rust or
other corrosion that may be on the steel for
the entire area that will be covered in cold
galv.
Also, you want to be sure to remove any chemicals,
or dirt, grease, grime, that kind of thing
from the surface.
Cold Galv can be applied just like paint.
It can be rolled on, brushed, even thinned
down and used in a sprayer. There are also
aerosol version available.
The higher the zinc content, the better you're
protected. Since the zinc bonds to the steel
to form that protective layer, the more zinc
in your cold galv the better your protection.
Most likely... Cold Galv can be applied in
a lot of different environments. Be sure to
check the manufacturer specifications for
your particular brand. Extra humid weather
can actually intensify the reaction and speed
up the drying process.
Unfortunately not. Cold Galv can only be shipped
ground or LTL. The government does not allow
it in the air system so it can't be overnighted
due to its category 3 classification as a
flammable liquid.
