I painted my cast iron tub a few months ago with oil-based exterior
white enamel paint. It looked great at first, but now it's starting to
turn more of a cream color.

Thinking it was just dirty, I hit it with some "Soft Scrub with bleach"
and it didn't help. Is the paint yellowing, or is it something in my
water? I have old galvanized pipes through the house and it is a bit
rusty, but all the paint seems to all be the same cream color, even
areas that aren't ever directly exposed to water, only to steam.

If it is the water, is there some sort of urethane clear coat or
something I can spray or roll on that will hold up to the heat, water
and chemicals?

You've just discovered why nobody paints cast iron bath tubs. Before you
painted, what was the surface like? Old messed up porcelain?

That is not the proper way to re-coat a tub. There are some epoxy paints
for just that, as well as some methods used by professionals in that line of
work. I think you have a lot of work ahead of you.

I a previous posting where I gave a professional answer to
your question about searching for tile, you answered by
trashing me and saying:

"This is part of the reason why I'm doing this project myself, you
never
know what to expect when you hire folks like "thetiler" to do work. "

What you get when you "hire the tiler to do the work" is a person
who doesn't wing-it by painting a bathtub and tile with exterior paint,
especially without a primer. Did you remove every bit of soap film
or residue? Did you etch the surface? Did you research the proper
"paint" to use?

A professional does work that won't fail under ordinary circumstances
and is guaranteed to be right.

If you are a professional at something feel free to give advice
and make judgments in that particular area, but if you're just
winging it all the time, as least be open to professional advice
and don't try to correct it if you have no idea what you're
talking about.

IMO the thing that spoils alt.home.repair the most is all the
wrong advice that's thrown out into cyberspace.


the tiler

It was 'messed up' porcelain before... it was very etched and it just
wasn't looking so hot.

The paint is more of a cream color than yellow...it's just that I've
just put in some trim that I painted with the same gallon of paint, and
it is a few shades whiter than the tub. If it is the paint causing
this, than I guess I'm just going to have to accept a cream color
instead of the gleaming white.

Just to entertain yourself, did you read the instructions on the paint can,
before or after the debacle?

maybe that's rust leaching through
oil takes a very long time to dry

did you prime the steel first? the primer comes in a spray can.
it converts rust to a permanent paintable surface

I did the same thing. I painted steel with oil paint. i did use the
primer..
so far no leaching... the stuff works great
--

The iron wasn't exposed in that tub... and I painted the ugly 60's
green tile surround at the same time...and it's turned cream color as
well.

I've painted molding with this stuff before and it hasn't yellowed at
all. I figure it's got something to do with the water or heat or
something that the shower is exposed to and the moldings are not.

Thanks for all the help gents. The cream color is kinda growing on me
now that I know I can't just scrub it off or something.

i bet it is growing on you, lol

maybe your lighting will make it look perfect
like candles, or lower watt bulbs?

Exactly what paint did you use for this? Make, model, link, etc.

Sounds like you used whatever you had instead of paint specifically
intended for this purpose. And exactly how did you prerare the
surface? How did you apply the paint?

it was a rustoleum product, it's called a rust converter, oppossed to
being a blocker
it's creates a chemical reaction in the steel.. vs.. masking it.. they
only sell one brand at lowes or hd...

i painted 8 - 8x8x20' foot steel sq tube columns

i used a scraper to get the existing peeling paint off, then buffed
the rusted places with a wire brush... you're not gonna get all the
rust off.. and it dont' matter.. you'll be converting the rust..

nah, i bought what i needed for the job

i wanted a converter and oil paint

it was the fastest 500.00 i ever made, the owner was furios
he says, you didn't tell me it would only take 3 hours.

SOOO!!! pay up sucka! the job is done..
the work is worth the price, it's non-negotiable

damn indians

Oil paints yellow over time, especially if not exposed to sunlight. You
should have used an epoxy, probably.

I think your biggest problems are using a rust converter instead of
completely removing the rust, and using the wrong paint. I'd remove
all the paint and rust and try again the appropriate materials..
