Want your paint jobs to be impeccable? Start with True Flow Gesso Primer, which helps best prepare the surface you wish to cover with acrylic or oil paints! Works best on surfaces such as canvas, paper, wood, fabric, panels, and other common materials. Thick, deep black gesso offers the advantage of good tooth (texture), adhesion (sticking/coverage), and water-resistance to surface. Smooth and easy to spread; can dilute with water if you desire a thinner coat. If you desire an ultra smooth surface coat, rub sandpaper gently in between each layer; ensure that gesso or paint is completely dry before doing so. One gallon size provides endless use for arts and crafts in the classroom or home. Non-yellowing. Freeze/Thaw stable. Non-toxic.
