The Proline Decorative Concrete Systems Dura Antique Release AR642 is 30 lb Light Copper Powdered Color Agent. Proline Dura Antique Release is used as a bond breaker in the stamping process. It is a dust-on powder with water repellent properties that helps prevent wet concrete from adhering to the polyurethane texture mat. PROLINE DURA ANTIQUE RELEASE is also used as a coloring agent, leaving a portion of the color, usually darker than the concrete color, imbedded in the low points of the newly textured concrete. This product should be broadcast in thin, even coats that overlap just enough to produce a uniform layer on the slab surface. Release powder can be thrown by hand or with a 6” mason’s brush. Stamping can begin as soon as the release agent is applied. Allow concrete to cure for at least 24 hours before removal to prevent damage to the brand new surface. Removal is accomplished by brushing then rinsing with a garden hose spray nozzle, light pressure wash, scrubbing, or buffing. Remove only enough to achieve desired antique effect. Final color that matches the color chart can only be seen by sealing with a quality concrete sealer such as PROLINE High Gloss Dura-Seal.
