Degreasing Metal Before Painting

Using a degreaser is one of the most important steps to preparing your metal for successfully applying your primer, base, and top coats. If the surface is not performing adhering to the paint correctly or the job ends up wacky, there is a 90% chance that you did not take the time to prep the metal surface well.

Perhaps the first thing you need to know about a well-prepped metal surface is that it will be water-break-free. This is an expression by auto spray technicians that when you pour water on the metal, it will have an unbroken thin film of water spread all over it.

But when an inadequately prepped surface usually has beads of water on it that runs off instead of a thin film of water. This evidence of the metal surface’s inability to support a thin film of water is how you know when your metal has been properly degreased and prepped before painting.

Again, the first step to cleaning the contaminants is degreasing. Make sure to read the instructions on the product you are using, as some have tips that can help you get better results.

You want to wipe down the metal first. Ensure to apply heavy pressure as you wipe the metal surface down. Apply with such pressure as though you were buffing wax in a car.

After wiping the metal surface dry, vigorously wipe the metal surface down again with any of the three products above.

You can rinse the metal surface under distilled or deionized water to test. Although you can use tap water if deionized water is unavailable, tap water is not recommended. The metal should have unbroken water break-free surface. The water should make a thin film on the metal and remain on the surface without beading up for at least 30 seconds.

If this is not the case, dry the metal surface and repeat the procedure. It would be best to ensure that the metal is dry before applying your coatings over it.
