Proline Decorative Concrete Systems EZ-Tique TQ-614 3 lb Rock Gray Antiquing Wash Powder Pack. Proline Duracolor Ez-Tique Antiquing Wash is a versatile coloring agent that can be easily applied and, like powder release, is bonded to the surface when sealed. It is sold as a powder but is designed to be mixed with water and applied as a liquid wash coat. EZ-TIQUE can be used to revitalize a weathered concrete surface or add an antique color to a freshly textured surface. It goes on quickly with greater control of the coloring process. This product is water based, non-hazardous and zero V.O.C. Use between one and three scoops per one gallon of water, depending on desired effect. The product, once mixed, needs to be agitated during application. Before applying to unsealed concrete, it is helpful to pre-moisten the surface with water so the liquid color will have time to even out and settle properly. EZ-TIQUE can be spread quickly with a clean push broom. EZ-TIQUE can be cleaned up readily with water.
