Challenges and Considerations of Painting Over Powder Coating
Achieving proper adhesion between liquid paint and smooth powder coating can be challenging.
The difficulty of adhesion between liquid paint and smooth powder coating
The paint does not stick well to powder coating. This is because the surface of the powder coating is very smooth. It needs a rough area to hold onto. If you do not roughen the surface, the paint will peel off fast.
You need to sand it before painting, but not too much! Too much sanding can harm the coat underneath. You must be careful and patient for good results.

Proper surface preparation and priming
Getting your surface ready is key. Powder coatings are hard and paint does not stick well to them. However, if you lightly sand the powder coating before painting, this can improve adherence.
Sanding makes the surface less smooth and helps the paint hold on better.
Priming is also a big step in painting over a powder coat. A primer helps prep the surface and creates a strong bond between the paint and powder coat.
Zinsser Bulls Eye 1-2-3 Primer Sealer works great for this job! Just apply it after sanding but before painting.
This way, your paint will last longer on the powder-coated item.
Steps to Paint Over Powder Coating
Apply a suitable primer followed by the desired paint for a professional finish.
Cleaning the surface with wax and grease remover
Get your surface clean first. Use a wax and grease remover. This will take off the dirt stuck on it. It also takes off any oily spots. Now you have a clean area to work with for the next step!
Using sandpaper to roughen the surface
To help paint adhere better to a smooth powder coating, you can use sandpaper to roughen the surface.
By lightly sanding the powder coating with sandpaper, you create small scratches and provide a textured surface for the paint to grip onto.
This improves the adhesion of the paint and helps it stick better. Just be careful not to sand too hard or remove too much of the powder coating.
Applying a suitable primer
To ensure that your paint adheres properly to the smooth surface of powder coating, it’s important to apply a suitable primer.
A primer creates a bond between the powder coating and the paint, improving adhesion and durability.
One recommended primer is the Zinsser Bulls Eye 1-2-3 Primer Sealer. This particular primer works well for painting over powder coat because it helps with adhesion and provides an even surface for the paint to adhere to.
By applying a suitable primer before painting, you increase the chances of achieving a smooth and long-lasting finish on your project.
Applying the desired paint
Once you have properly prepared the surface, it’s time to apply the paint. Choose a paint that is specifically designed for adhesion to powder coating, such as epoxy paint.
Using a brush or spray gun, apply an even coat of paint over the entire surface.
Make sure to follow the manufacturer’s instructions for drying and curing times. This will ensure that your newly painted surface is smooth and durable.
Remember that different types of paints may require different application techniques, so always refer to the product instructions for the best results.
