Can you paint radiator pipes?

The copper pipes coming off our radiators are quite visible and look a bit scruffy. Can you paint over copper pipes without it peeling, and what paint do you use?

"Yes!

Quick & useful process (simple version)

1. Turn heating OFF
Pipes must be completely cold
Painting hot pipes = paint failure + smell

2. Clean & degrease
Wipe with sugar soap or degreaser
Remove dust, grease, old residue

3. Sand lightly
Use fine sandpaper (120–180 grit)
Just key the surface (don’t overdo it)

4. Prime (important)
Use metal primer (or direct-to-metal paint if specified)
Especially needed if:
pipes are bare metal
or have rust spots

5. Paint (2 thin coats)
Use radiator paint / metal paint (heat resistant)

Finish options:
Satin (most common)
Gloss (durable, but shows imperfections)"

"Hi Lauren, yes copper pipes can be painted. I would always recommend oil based gloss or satinwood. Kind regards Steven"

"Hi, yes you can with specialist paint like radiator paint or high heat Enamel. You have to clean them and use a primer first. I would choose pipe covers, they look alot nicer 👌🏼just search radiator pipe coves"
