Hello,
We recently replaced the copper gutters and downspouts on our historic house museum. The exterior of the building is maintained to its c.1969 appearance and in 1969 the copper gutters and downspouts were painted to match the trim and stucco. The gutters have been up for about two years now (unpainted) and the downspouts were installed a couple of months ago. Is there any prep work necessary before applying paint? Is there a certain type of paint that is better to use on copper? Any and all information / advice will be greatly appreciated.
Thank you!

Sure, I can help you with that. First, I need to know a little more.

Is the copper lead- or terne-coated?

What is the condition of the copper that has been up for two years? Is it still shinny/pink? Dull/brown? Or, has it developed a green patina? (you may have to check inside the trough as that may be different that the outside.)

Are the copper joints soldered or sealed. If sealed, what sealant was used?

Also, what is the material of the roof that drains into the gutters?

You may not want to. I get a lot of reports about the thieves who steal copper gutter and downspouts.

My personal preferance would be to not paint them at all.

But, if the gutters are only two years old, you should be able to simply rub them down with laquer thinner and apply a good quality primer and paint. They probably have not had time to oxidize yet.

If you want the gutters to last a really long time, paint the insides of both the gutter and downspout. You might need to scrub the insides with steel wool or similar.
