Buying Guide

1. Type Of Primer

Primers are widely available in the market, some claiming to be the best for all types of surfaces. Aluminum is not like any other metal surface wherein it is just a straight-up application. 

But, it does follow the same painting process just like any other surface except for the materials that you would need to use.  Primers in particular have a very critical role to play when it comes to painting.

It does not only protect the immediate surface from corrosion but, also acts as an adhesive to the topcoat or paint. 

2. Primer Formulation

Primer formulation should be taken into consideration since as discussed earlier, not all types of primers are fit to work on aluminum. That is because aluminum in nature forms a thin layer of aluminum oxide on its surface. 

This makes it challenging for most primers to adhere unless this thin layer is removed. The key here is to apply a primer with the correct formulation on the aluminum surface.

These are called self-etching primers. What these primers do is remove the oxidation that naturally occurs on the aluminum’s surface.

It needs to be intricately applied as well otherwise, your topcoat will not adhere to the surface properly. Your paint layers will end up peeling in no time after it is applied. 

For canned primers, what you need to do is to thin the primer based on the manufacturer’s recommendation. You need to do this correctly to get the right formulation. 

Once you have cleaned the metal’s surface thoroughly, you may now start applying the primer and let it stand until it dries. 

3. Durability

Like cars, your garage doors are exposed to various extreme conditions daily. Good thing most primers for aluminum applications are specially made for cars.

Aluminum is widely used for various high-stress applications, thus it also needs to be protected to avoid any form of corrosion. And for your garage door since it is exposed to different weather conditions, only use the correct primer for the job. 

4. Ease Of Application

If you are opting for spot painting, then aerosol primers would do the job just fine. But if you are painting a large surface, then get the ones that come in big cans. Just make sure that you dilute the formulation the right way.
