Porter’s Patina Green is a solution for use over Porter's Liquid Copper. A chemical reaction between the Liquid Copper coating and the Patina Green solutionoccurs to recreate copper with the green patination of age.
Cleaning materials
Water
Application Tools
Brush
Not suitable for “high traffic” surfaces such as hand rails, door knobs etc as continued touching of the surface will remove green patina effect.
Please Note: Liquid Copper treated with Patina Green is a chemical reaction. Individual results may vary due to film thickness, methods used, time elapsed, ambient temperatures, substrate etc.
The green patina effect can be delicate, and the application of clear coats or finishes over the green patina effect will remove some or all of the finish, and this can leave the Liquid Copper visible without the Patina Green finish.
Do not apply in high humidity, below 10°c or above 30°c.
For best results apply Patina Green when Liquid Copper is touch dry, or within 12 hours of the Liquid Copper being touch dry. This is because the longer the Liquid Copper is left to dry the harder the paint resins will become, and the Patina Green will take longer to react with the copper particles.
Caution: Please always wear rubber gloves and safety goggles (refer to SDS prior to use).
Within 12 hours of the second coat of Porter’s Liquid Copper being dry, lightly apply by brush two coats of Porter’s Patina Green. Allow minimum 3 hours dry time between coats. Green patination will begin to develop within hours and will continue to increase over the next 12 hours. To increase intensity of green patination effect, up to three coats may be applied. Allow each application to dry thoroughly before applying additional coats.
