Blasting, Priming and Galvanizing 101

Metal is one of the sturdiest materials in the world. This is why it’s used in everything from the construction of buildings to the fabrication of HVAC ventilation systems.

Though metal is engineered to last an incredibly long time, it is not impervious to damage. Water and air can cause oxidation, which in turn can gradually compromise the beauty and integrity of metal structures and surfaces until they fail.

The Complete Guide to Blasting, Priming, and Galvanizing

Blasting, priming, and galvanizing, however, are some of the best ways to repair and prevent damage to metal surfaces. Let’s examine the process to better understand what this process entails.

1. Evaluation and Preparation of Metal Surfaces and Equipment

The first step in restoring metal is evaluating how much damage it has incurred. Most metal surfaces exposed to the elements will experience minimal damage, which in turn leaves them structurally sound and ready to be refinished.

After the integrity of the metal has been evaluated, it can be prepared for the next step. This may require removing the metal, unbolting it, or simply cleaning it with a brush to remove certain contaminants.

2. Blasting the Metal Clean

The next step is to apply an abrasive to remove rust and any other mineral deposits that may have formed on the metal. This is imperative to ensure that the metal is just metal, which in turn ensures the longevity of the proceeding steps.

This step also gives the primer something to adhere to. This makes the primer stick better, which in turn produces a more favorable result.

3. Priming the Surface of Metal Products like Condensers

Primer acts as a protective coat when it is applied to metal. It can repair minor blemishes caused by damage that may have built up on a metal surface over time.

Primer acts to seal moisture out, which is especially important when HVAC equipment is involved. This gives the metal extra longevity while reducing the number of contaminants that “linger” on the metal.

4. Galvanizing Metal to Deter Further Damage

The last step in the process is galvanization. This is where a protective layer is applied to things like the insides of HVAC vents, condenser units, and other mechanical components where priming may not be appropriate.

Zinc is typically the main material of choice when it comes to galvanizing. This protects the metal from oxidation by allowing elements to bond to the zinc rather than the metal.
