BACKGROUND PAINTING
If you want an opaque background colour on you project, use an acrylic matt paint, those specifically made ofr folk art being the best. I like to use Jo Sonja's background colours. Using a 25 mm or 1 inch inexpensive brush from a hardware store, or a sponge brush, apply an even coat, watching for drips or build-ups in corners or routed edges, which take a long time to dry. I never mind seeing brush strokes and don't become too particular about smoothness because I rather like the streaky look when antiqued.
When dry, sand the piece well and follow with a second coat of paint, and then when dry, sand again.
