Fixing cast iron enamel
September 25, 2019 9:56 AM Subscribe
I've got a small chip in my cast iron shower pan. What's the best way to fix it? I've seen a bunch of kits that range from white paint to UV cured epoxy. Has anybody done this? Or is it a job for pros, and what kind?
If it's cast iron, there's a 100% chance of a magnet sticking, no matter the coating.
Better to check with the manufacturer's website, or the labeling on the product if you were to try to order the same thing. If you ordered online, check the deets in your order history.
You man also just season that one little spot of iron with a drop of oil and some heat, and then ignore the chip.

The color suggests cast iron, not porcelain. Rust is insidious, paint seems inadequate. I'd probably dry it well, and use the epoxy.

I’ve used (multiple coats of) white nail polish in the past, if cost is an issue. It didn’t look perfect but it looked better than before.

If it's rusted, you absolutely have to remove all the rust. This will involve removing the enamel around the chip as well, until you have clean, bare metal. Not removing the rust means the pan will continue rusting away under the old coating as well as the repair. Be sure to sand the enamel around the chip before you paint, to improve adhesion.
Enamel touch-up paint is pretty easy to find; the big-box hardware stores stock basic white. You need very little. It won't be as durable as the enamel that's baked onto the metal, but that probably won't matter; if your shower pan doesn't flex the paint is unlikely to crack. I hadn't been able to color-match the enamel in my tub when I had to touch it up (the tub was over 30 years old, so the once-white coating had aged), but it was close enough that I didn't care. Color-matching whites is difficult, particularly in bathrooms with no (or very small) windows.

we used this on our cast iron tub a few years ago and it seems to have held up fine. 2nding others suggestions to remove the rust first.
