Painting Outside of Cast Iron Bath Tub: Smart, Safe Advice

Summary for painting outside of cast iron bath tub Discussion

Painting outside of cast iron bath tub is discussed as a refinishing question rather than a simple repaint. Sue Thweatt asks how to change the tub’s white exterior to a vivid color and whether oil-based paint, acrylic topcoat, or a hard glaze is needed. James Watts replies that tub repair services likely use polyurethane-based paints, and he recommends checking with a tub restoration company to learn what a professional-quality job would cost and what materials they use. He emphasizes that prep work is more difficult than the painting itself. A later commenter, James Toole, asks about painting a claw-foot tub with rust and wonders whether a patina could create a black antique look, but no answer is shown in the excerpt. Overall, the thread points readers toward professional restoration methods and careful surface preparation rather than a simple household paint job.

Q. This tub in is great shape inside and out–but the outside is white and I want to paint it a vivid color to match the remodel of a bathroom we are doing. How do I simply repaint it and does this require oil based paint and should I top coat it with acrylic or a hard glaze?

A. I could be wrong, but I think that tub repair services use polyurethane based paints.
I would check with a tub restoration company to find out what a “professional” quality job would cost and what type of paint they would use.
Prepping the tub is more difficult than the painting.

Q. I have a claw foot tub and wanted to paint the outside of the tub. It has some rust that I will be sanding off, but what I wanted to know do they make a patina that would give the outside a black antique look to it. What type of paint would you suggest to have a antique look to it?
