Description Jo Sonja’s Retarder & Antiquing Medium Slow down the drying time of acrylic paints so you can have longer to work on the piece. For Antiquing, allow your painting to dry for 12 hours, then apply Retarder Medium mixed with your final colour choice. When no wet spots are visible, wipe off where you want the highlights. We have created a painting system like no other! Using a basic palette of colors you can create heirloom artwork at a fraction of the cost of using lower quality craft paints. Jo Sonja’s painting system allow you to paint on wood, metal, glass, tile, fabric, walls, floors or virtually any surface using one set of paint. The secret? Jo Sonja’s Artist’s Mediums, which allow you to control the paints under a variety of conditions. Related
