Описание: Have you ever painted on copper?!! ✨🟧✨

Thx Artefex Art for the panels!!

I’m still new to painting on copper so I’d love to hear any tips & advice you have about the surface! ✍️

Copper panels seem to be growing in popularity (at least on my Insta feed) but they have actually been used since the renaissance. It’s a very stable painting surface as it doesn’t warp. These days aluminum & copper composite panels (ACM & CCM) like this one provide even more stability & longevity. I’m thinking of ways to incorporate the metal into my paintings & allowing it to show through. You may also like to know it comes ready to paint on.

What I’ve learned lately is that copper takes a little bit of extra care. It can oxidize over time & avoiding finger contact with the copper surface is essential to prevent oil and moisture transfer, which can interfere with paint adhesion and lead to corrosion.

To prepare a copper panel for painting, follow these steps:

1. Always use gloves or clean dry hands to touch the surface.
2. Remove oils, dirt, and contaminants using rubbing alcohol or a copper cleaner.
3. Keep the panel in its bag until it’s in use.
4. Finish by varnishing the full surface (including the back if it’s also copper) to prevent oxidation.

Here’s how to clean finger marks & smudges from your panel:

1. Get a soft, lint-free cloth or a cotton swab
2. Use isopropyl alcohol in a diluted form, 70% or lower.
3. Apply the alcohol sparingly and gently to the area.
4. Dry the copper surface to prevent any moisture from causing tarnishing or corrosion.
5. If corrosion is still evident & alcohol didn’t remove oxidization use copper stain remover by Rublev using a lint free microfibre cloth. Then use alcohol to clean off the entire surface. Finally use Rublev copper rinse to stop any further corrosion.
