Primer for copper CH pipework ?

Hi. I have a short length of new bare copper CH pipewok to paint and wonder if the Zinsser Bull Eye 1-2-3 I alrady have would be suitable as a primer, as I could find no specific mention of "copper" in their literature ? Many thanks.

Zinsser BIN, Smith & Rodger Blockade, or even clear knotting solution. Needs to be shellac. I wouldn't trust 123 over copper.

Anything else is liable to turn green.

I was taught straight on with oil based gloss - but haven't gone back to check those jobs 30 years later.

I've used oil-based satin straight on to new copper pipes. I've seen some of them several years later and they still look good.

... and, I should add, one of your Tiger Kit Paint Stirrers - the best! got me out of a real hole a couple of weeks ago. I had a 5ltr tin of tinted emulsion that the supplier had added the tint to but had forgotten to mix. The job I was on was miles away from the supplier and it would have buggered up my schedule if I'd had to go back to them so I used your paint stirrer and it did the job perfectly. Highly recommended.

Thanks Tom that's great to hear.

The important thing with copper is to clean and degrease it before painting. Just don’t polish it!
