Cast Iron Pipe

[AfroJoJo]

This is the main vent stack in our basement. It's getting rusty looking black oil/sludge sections on the hub joints. It doesn't have any odor to it, it just looks bad.

Is there any way to handle this without removing and replacing the pipes? I know it will eventually need to be replaced, but is there something I could do to make it look better?

Would it be ok to paint right over that stuff? I figured it would bleed through right away.

Before painting

Gently pack the lead back in to the joint a small hammer and chisel GENTLY

Get some Goof off 4.5 ounce can and it will remove the oil from the okum then you can paint it

FYI

"This is the main vent stack "

Stack vents do NOT require a cleanout soil and waste stacks and leader lines do

Yeah, I've the same issue. Stuff smells like tar, I'm afraid it'd seep up and through.

@Sylvan : You're saying I could use goof-off to dry it out so I could paint over it ?

@AfroJoJo : I know its just been a few days, but did you try it yet?

The pipe is coated in asphaltum , that's how its made. clean it, prime it, shellac it, paint it.

@James Henry :

Clean it: Goof off?
Prime it: Any advice on paint ?
Shellac: Cool, very nice, will do.
Paint it: I assume at that point I could any paint?

I would wipe the whole pipe down with a citrus based cleaner then rinse, PVA Primer, sand down shellac finish, the imperfections will show in the paint. I would use a latex paint in case you want to paint over it. There will always be tiny movement in the joint of the stack so don't count on it lasting forever.
