To get a smooth finish with chalk paint, there are different methods to achieve it. One method is to sand the chalk paint with gradually finer grits of sandpaper until the final grit is smooth. Another method is to paint the surface as smoothly as possible with a high-quality brush or roller, feathering the paint lightly to reduce brush marks, and then sand the surface with a fine sanding pad before waxing. Waxing the chalk paint with a cloth and buffing it to a sheen can also create a smooth and velvety finish. Some brands of chalk paint are self-leveling, which means they eliminate brush strokes as they dry and cure. To achieve a solid-color finish, apply two coats of chalk paint with a chalky paint brush, getting into all the cracks and crevices. Alternatively, use a high-density foam roller to apply the chalk paint in unidirectional strokes .
