Greetings to the group:
This post seeks info on removing drain rust beneath a 1962-era cast iron tub before resurfacing.
I inspected the bottom of my tub, from the crawlspace. Some fresh-looking rust is emerging from between the shoe gasket and the tub bottom. It has spread to about 1/4 inch beyond the gasket, in all directions. The drain assembly is brass.
My sense is to disassemble the drain, remove rust with naval jelly, sand surface a bit, and then prime and paint. I can work in the crawl, and have cut an access panel to reach tub back.
Can anyone suggest steps for rust removal? How about for steps to treat the metal to prevent rust before i put the drain back together? Any comments or criticism would be stellar
EDIT: Thanks for the reply (to answer your ?, I don't know the condition of the tub interior because the "flipper" from whom we purchased the house this year had the tub resurfaced just about 10 months ago, and the new surface is starting to peel--we're irritated as all get out, but have no recourse).
Here, for all, are some pictures of the rust that I am trying to remove, in the area at which I'm seeking guidance here. Took these this morning from the crawlspace:
The image of "east side" shows the area of heaviest rust.
Image of "west side" shows much less rust, in a spotted pattern. Could this spell trouble?
The image "overflow side" shows that side of the tub, just for completeness.
Again, if anyone can offer guidance on steps to remove this rust, and steps to take to prevent recurrence, I would really appreciate your views and/or criticisms.
