suppliers. The patching compound quite often is a two-part component.
These components should be thoroughly blended to the correct consis-
tency and color. The repair procedure accompanying the patching mate-
rial should be followed to ensure a proper repair.
Galvanizing Repair for Metal Attachments
The repair area should be cleaned to thoroughly remove all rust, grease,
and other contaminants. The area should be totally dry and clean prior to
coating. The coating Manufacturer's repair procedure should be followed.
For different applications and size of damage, the repair material and
methods may be different. Examples may include a zinc-based solder
(“hot-sticking”), spray zinc (metalizing), paint containing zinc dust, or a
zinc-rich paint (“cold galvanizing”). ASTM A780/A780M (ASTM 2009)
should be followed.
