What happens if you spray paint galvanized metal?
Alkyld-based spray paints will react with the zinc during any stage of the galvanized layer, in a process called saponification. The alkyd-base interacts with the zinc to form a soap at the interface. This will result in poor paint adhesion and paint peeling.
Does zinc spray stop rust?
The zinc provides the metal surface with a cathodic rust protection and the resistant synthetic resin film offers optimal protection. The zinc spray does not need to be over applied, brief spraying is enough to achieve a protective film of 20-30 microns.
