As an experiment, I painted some PVC at my house. The PVC is exposed and outside. It's right near the door and I didn't like being able to see the writing on the PVC. Just to see if it would work, I painted about a foot of it with grey automotive primer out of a spray can. It's made it through two hot summers and two winters. So far no flaking or peeling whatsoever. As soon as it gets warm again, I am going to do the rest of the run.

You may not have the same results with black, unless you use black primer. I think most any gloss would be problematic over time, but that is just a guess.

Krylon and others make paint designed for plastic. Never tried it.

I have seen it used on car dash boards. After a few years, it flakes off. But that was on plastic that moved quite a bit. Still it did flake off and looked like it never bonded to the plastic.

I found this on a blog about Krylon Fusion paint: (New product, not the stuff I saw used on car dash boards)

PVC is difficult to paint because of its molecular makeup: it basically provides no rough surface to adhere to. If you try to paint PVC with standard paints, you end up with a layer of paint that is flaking, peeling, or bubbling, and often just won’t stick.


That was the case until the invention of Krylon Fusion Paint for Plastics. It’s honestly the only paint available which can actually, and successfully, stick to PVC, since that’s what it was designed for. It comes in a plethora of colors and is available at your local hardware store or home center.

What if the PVC is not a raceway as defined by article 100?

Example, luiminare cord connected per 400.7 with part of the cord slid through a piece of plumber's PVC which had been painted black. The reason for the PVC is simply asthetics.

I don't know, that would be an AHJ call would it not?

As I look at the restrictions for cords, not through holes, not through walls, not through ceilings, not in ceilings, not attached to building surfaces, etc, it is my opinion that even sleeving it goes against the NEC.

If 'sleeving' it went against the NEC, why don't they just say it?

400.8 does not just say 'concealed'. They are specific about what type of concealment is prohibited and I just don't see 'slid through plastic pipe for asthetics' as one of them.

Would it be against 400 to slide 'split loom' corrugated plastic meant to be used with copper tubing over the cord?
