Eco-Flo Cova Color is a water based, low V.O.C., acrylic paint for use on natural veg-tanned tooling leather. Colors are opaque when used full strength, but may be thinned with water to reduce intensity. If enough water is added, Cova Colors will become very transparent and can be used as a "wash" to tint large or small areas. Colors may be mixed to form many different hues. Directions for use: Shake well before use. For best results, apply Cova Color with good quality artist brushes or a sponge brush. More than one coat may be applied if needed. Allow to dry completely between coats. Clean up immediately with soap and warm water.
