Product Information

Now you can add another level of design to these individual products with our new tinted lacquers, Brass and Copper.

The use of rotating mops and pads can be an excellent way of rapidly obtaining a good finish on copper and brass. NEUTRALIZE ACIDS – Acid traces must be removed from the surface otherwise black marks/dark cloudiness will appear under the coating. To remove years of stubborn tarnish build up you can use our environmentally friendly Copper Cleaning Gel.These can be effective in the short term but leave a surface that is active and tarnishes again quickly. PPG recommends the application of their acrylic urethane (catalyzed) DAU 75 after having finished the metal cleaning and conditioning steps on brass, copper, and aluminum that is to be clear coated.

You need to remember that finger and hand prints leave acid traces on copper so it is important to wear nitrile gloves (not latex) when handling the copper after this neutralising step up right up until it has had its first coat applied.

If the surface is not smooth, a nail brush should be used to ensure there is no polish left in the crevices. if my hunch is correct and the conditioning step would leave a protective surface film on the copper much as it does on aluminum.Rustins Metal Lacquer is a low solid lacquer based on a polymethacrylic ester dissolved in a mixture of Ketones, Alcohols and Hydrocarbons. Good pressure is needed when polishing, since this actually smoothes over the ductile surface of the metal and helps to obtain the required mirror-finish.

Tableau anti-tarnish lacquer spray is the easy way to give long term protection to all bright metals, including silver, copper and brass.Below is a view from underneath a penholder base that has been polished away completely on the edges and corners. It is best to recoat before any tarnish or oxidation is seen or at the first sight of slight colour change. From looking at the photo it almost looks like it’s been in a barrel polisher for 10 hours and then left wet. Add common salt to the cleaner if something stronger is needed but always ensure that all traces are washed off brass as traces of chloride can be aggressive to heavily cold-worked metal.

Having said this the copper would conduct the heat through so I guess that it would not crack or melt the lacquer unless the there was directly applied heat.Others, such as the patina on statues erected in the outdoors, need periodic cleaning and re-protection. Once the metal is clean, Everbrite™, ProtectaClear® or CrobialCoat™ can be applied by several methods. A bit extreme but it will show the effect and how much heat it can take and then a decision van be made on the distance from the fire.
