Sponging is a quick faux painting technique and an easy way to freshen up a space. This faux painting finish can be done with water-based (mixed with acrylic scumble glaze) or oil-based paint (mixed with mineral spirits or oil scumble glaze). Choose 2 or 3 colors which are tonally similar. The base coat should be a semi-gloss for water-based paint and an eggshell base coat for an oil-based paint. The last color will be the dominant color.
