Paint sponges are used on interior walls and furniture to add a textured appearance. Sponges also apply decorative finishes on top of walls and objects already painted a neutral color. Painter's mitts are multi-layered, lined gloves that provide protection while applying paint or stain in hard-to-reach areas or on oddly shaped surfaces. Cloths are cotton cheesecloth squares used for staining or varnishing wood surfaces. Since cloths are thin and pliable, they saturate quickly to fill wood grain and cover surfaces smoothly.
