Acquiring and spraying the paint really depends on the equipment and experience you have. Our paint system is only recommended for spray applications and is really designed for a larger production spray line environment.
Usually, we recommend simply taking a paint sample from your actual project, meaning take one of the doors from your new cabinet order and have your local paint supplier match that exact door color and sheen. This helps prevent most issues with color mismatches, and they can formulate the paint in a way that is easier to apply on site using the tools and equipment you have available.
