Wet painting is a traditional process of applying liquid paint to a metal.
There are three main ways to paint with liquid paints:
- Automatic spray painting
- Hand spray painting
- Dip painting
Liquid paint in industrial settings is applied with by spray, with pump, or pressurized vessels or in immersion tanks to ensure even coating.
The piece is first cleaned thoroughly. Following this, paint is applied.
Wet paint may require multiple coats to ensure an even finish.
Wet painting is relatively cheap, especially when looking at startup costs. It also allows for thinner coats that are out of the question for powder coating.
Wet paint can also be used on rubber or other heat-sensitive materials since curing occurs at room temperature. If the product becomes scratched or damaged, touch ups are much simpler than powder coating.
Wet paint also provides a greater range of colors and finishes, when applying with spray technology.
There are a few drawbacks to wet paint. It is by no means as durable as powder coating. If bending or scratching occurs, the paint is liable to chip or splinter. Because of this, maintenance over time will be greater than powder coat. Multiple coats are also needed in wet paint; however, only one coat is needed in powder coating. Because of the wet application, drips or other imperfections in the finish are possible.
