Hey, can we discuss cast iron bathtubs? Ours has some chipped paint and grime around the drain that we can’t seem to get rid of. Any suggestions on how to clean it up and repaint the tub? I’ve included some pictures for reference.
When repainting, consider using muratic acid or high-strength 70 to 90 percent ind vinegar. Both can be harmful if inhaled or touched. Make sure to wear a chemical respirator, long sleeve chemical gloves, and a face shield for protection.
That does sound intense, .
The black staining is likely from mildew and other sources. You’ll have to sand down the areas that are chipping and flaking. The materials used to refinish the tub are not the same as regular paint. It might be helpful to do some research on the process or consider hiring a professional.
I wouldn’t recommend doing this as a DIY project. There are affordable businesses that specialize in tub resurfacing.
Alright, I’ll have to check out what options we have in our rural area.
I’ve been installing epoxy for 6 years, working on counters, vanities, tables, and more. The company I purchase from recently released a new tub epoxy that’s 20 times thicker than permacreme or other options. Check it out on countertopepoxy.com. It’s O VOC and super easy to use, I’ve tried all their products except the tub epoxy. They also offer great support.
You could try painting it yourself, but the results might not last. For a truly professional finish, it’s best to leave it to the experts who have the right chemicals and paint.
Definitely hire a professional because it will last a long time and look way better.
You might need a certain type of acid for cleaning. There are some options available, but they can be harsh and are typically used for outdoor cleaning. So be careful. When it comes to refinishing, epoxy could be a good option. I’m not sure if there’s a specific one for tubs, but if you’re just planning to paint over it, consider using epoxy. Look for one with a non-slip feature too.
It’s time for a replacement
