How to paint on plywood art?

1. Start by sanding the plywood with medium- or fine-grit sandpaper to create a smooth surface.
2. Apply a coat of primer. Make sure to use one that is tailored for the type of paint you intend to use.
3. Once the primer has dried, use a foam brush or roller to apply a thin and even coat of latex or acrylic paint.
4. Let your first layer dry completely before adding additional layers, if desired. Use a smaller brush or sponge to add details as desired.
5. When you are happy with the painting, use a polycrylic or polyurethane sealer to protect the paint from scratches and fading.
