When working with cardboard, it’s important to choose the best possible paint, as this will affect the final look and finish of your project. The best paint for cardboard is typically a water-based acrylic paint. Acrylics dry quickly, are easy to apply, non toxic, and can be cleaned up with soap and water.
When choosing a paint for cardboard, it is important to consider the type of finish you desire. If you are looking for a high-gloss finish, you will need to use a paint that is specifically designed for that purpose. If you are looking for a matte finish, you can use a regular acrylic paint.
