"Cast iron Hook-pes Bathtubs: How to Make clean, Remove Rust & Stains, Restore, Re-surface, Recoat"
An ongoing give-and-take beginning back in 1998 ...
1998
Q. I'm searching for info to restore a cast fe bathtub. The within does not need re-enameling so I plan to wire brush the exterior paint and apply a primer, then motorcar enamel. The feet take most a polished look from wire brushing. I have used a brass wheel attached to a Dremel [affil. link to info/product on Amazon] to clean them upwardly which has worked and then well I may just lacquer them! Anyway what I intended to advise is 19th century jewelry was oxidized black to preclude rusting.
Converting the surface to black iron oxide (Iron3O4) prevents rusting and may requite the desired issue. Clean atomic number 26 is submerged in highly full-bodied salt solution (commercially bachelor) for 15 mins at temp. of 290-300 °F then rubbed with a sparse film of sweetness oil.

A. Hi B. The black oxide procedure yous are describing is withal widely washed on things today. Industrial gears, sprockets, couplings and chain are black oxided. Although the corrosion resistance is quite express, it'southward an attractive finish that doesn't change the dimensions of the objects like plating or painting does. The same process is widely done on firearms, although people and so tend to call it "blueing" rather than "black oxiding". When it'southward practical to a rough surface it comes out matte black, but when done on a highly polished surface information technology'south comes out closer to a precious stone-similar navy blue. These are finished surfaces which are not after painted. Information technology might have been used on some of the claw feet of cast iron bathtubs, merely I'1000 not familiar with that. A gun shop can exercise this process for you lot.
When you intend to pigment a surface, you lot would instead use a phosphoric acid formulation called naval jelly or rust converter to convert red rust to that Fe3O4 black rust; this is something which whatsoever home owner or hobbyist tin can easily do, and you lot can certainly exercise to the OUTSIDE of your tub if there is any rust. Good luck.

A. The thing is, Neil, that the original terminate was probably porcelain enamel, more similar glass than paint -- a ceramic frit (powdered glass) is melted and fused at extremely high temperature onto the bandage iron. You can't practice that, sorry; so y'all're restricted to paint (which simply isn't nearly as good) or finding a porcelain enameling shop to do information technology for you.
2nd best is to hire a professional person tub refinisher who can do a good job with premium quality enamel paints. Tertiary best is to buy specialty porcelain repair enamel [affil. link to info/product on Amazon] fabricated for that purpose and do it yourself, recognizing that this will non approach the durability of a factory-practical molten blanket. Skilful luck.

Refinishing claw feet of cast iron bathtub
2001
Q. I would like to know how to refinish the claw feet on an old cast iron bathtub making information technology brass coating. Whatsoever information would be helpful.

A. Howdy Robin. Brass colored paint and contumely plating (real metal) are not the same thing, so you'll need to decide whether yous can settle for the paint or must have real brass plating.
Although it is non completely incommunicable for a hobbyist to practice whatsoever metal plating at domicile, brass plating on cast iron would involve sandblasting the cast fe, acid pickling it, nickel plating it (both for shiny appearance and considering you can't plate brass directly on cast iron), then contumely plating (this is cyanide based), then several well-applied coats of brass lacquer or a 2K automotive clearcoat. In short, if y'all want real brass plating, realistically you'll demand to be able to remove the claw feet and transport them to a plating shop.
If you can settle for brass colored pigment, get any onetime paint off equally best y'all can by sandblasting if bachelor to yous, or past sandpaper and pigment stripper if diggings isn't possible. And so apply a phosphoric acrid based naval jelly or rust converter. Cast fe is porous and you'll probably have rust stain problems if yous don't do this. And so do a brass color outdoor paint, brushed or sprayed equally you prefer. Topping off with a couple of coats of articulate acrylic spray may requite a somewhat more than metallic look. All-time of luck.

A. Hi, Skadi. For the exterior, you can bargain with the rust with Naval Jelly [affil. link to info/product on Amazon] earlier repainting. If the within is porcelain, you lot tin can't really repair this yourself as the blanket is more like a melted glass than a paint. Merely you can probably touch upwards chips with an appliance enamel (porcelain repair enamel [affil. link to info/product on Amazon]), and if at that place are rust stains, lots of people on topic 8229 swore by hydrogen peroxide [affil. link to info/product on Amazon]. Good luck.

Bath resurfacing
2004
Q. Hi there, I wonder if you can assist. I accept recently bought an erstwhile roll-top cast iron enamel bathroom and experience that it could do with being resurfaced in some way. I am aware of many bath 're-enameling' products bachelor but know that they are enamel paint rather than real bathroom enamel which is made of glass & other things. The longest balls whatever visitor tin can requite for their bath enameling products is effectually 10 years if washed properly and looked later on with supreme intendance. I asked a friend who works in a garage whether enamel could be spray painted on using his motorcar painting equipment and he suggested powder blanket the bath instead. Does anyone know whether this would work? Could the powder coating stick to the already existing enamel of the bath?

A. Rachel:
I have had this washed on two cast atomic number 26 sinks. Commencement you volition take to detect a powdercoater that is willing to take on the project. We first tried to sandblast the surface of the porcelain to roughen it for the coating to adhere to. The first sink took the powdercoating well,merely the finish was orange peeled considering the sandblasting was done likewise hard and left the surface of the porcelain likewise rough. The 2d sink had some pocket-size cracks in the porcelain that allowed out gassing and created large bubbles in the cease. Nosotros concluded up sandblasting the 2d sink down to the bare casting,sanding the surface polish,filling and sanding pits and craters in the casting with a compatible powdercoat filler and and so recoated the sink. Overall I am pleased with the results even though after several attempts the 2d sink even so had small out gassing (pinholes). Sanding the blank casting makes for a overnice cease but is very muddy and time consmming.
I hope this helps.

Remove Rust Stains Inside Cast Iron Tub
Q. I recently bought an old claw foot tub. It is in pretty adept shape but is stained. The stain is a light crimson-ish brown, like the clay around here. I have tried, bleach, Soft Scrub [affil. link to info/product on Amazon], Brillo pads and vinegar. No luck yet. Elbow grease does a lilliputian just not much.

A. As y'all have just purchased it I'1000 assuming you have not installed information technology. Which is good, Muriatic Acid [affil. link to info/product on Amazon] will consume through the rust, the porcelain coat will go on the rest of the metal from being eaten, do this in a well ventilated area as it will give off lots of fumes.

A. Hello, Ray; hi, Janie.
Although Marc knows his stuff, and his answer probably works, delight come across letter 8229 first ... because dozens of people swore by the simplicity, economy and effectiveness of hydrogen peroxide for removing rust stains from bathtubs, and I'd hate to run across hydrochloric acid used where a much safer & simpler approach can work. Good luck!

A. I had the same dilemma as Ray West in Texas. I tried everything, so I tried powdered Oxygen Cleaner (generic), I mixed 2 scoops in 4 cups of hot water, plugged the tub and let information technology sit down for 15 min., did this twice and it worked with very little scrubbing. Did the pull a fast one on.

Q. How-do-you-do,
I am refinishing an antique claw foot tub that we found in the barn (we just bought our farm). The tub is cast iron and the exterior is terribly rusted. I know how to refinish the interior of the tub (scrub, acid wash, rust inhibitor primer, enamel), but non sure of what to practice with the outside. I don't ain a sand equalizer, which is the but way I can think to remove all the rust before priming and painting. Is there some other style to prep the bandage iron surface for priming and painting?
Thank you!

Hi Jen. You need paint stripper designed to take off any it is that y'all put on :-)
There are some coatings that tin only be removed with Shipping Stripper (methylene chloride) -- merely it is truly noxious stuff you tin only use with gloves, goggles, and actually good ventilation. Hopefully a milder stripper like Citristrip can do it.

Q. I have an sometime clawfoot tub with deep gouges on the within. I alive outside the USA, and then can't get information technology professionally re-enameled, and in that location is no local adept on refinishing tubs. Someone hither has suggested filling the gouges with auto torso putty, sanding information technology downward thoroughly, and then spray painting information technology with car pigment. Will that work? Is there a item bonding amanuensis or primer that I should try to get, either locally or from the USA?

A. Hi Gopa. "You tin can't make a silk purse out of a sow'southward ear", and you make thick, glossy, wear-resistant, rock hard, porcelain enamel by spraying a molten drinking glass-like frit at extremely loftier temperatures; you can't brand porcelain enamel from body putty and spray paint :-(
It'southward non going to exist completely satisfactory, just y'all can only practise what you lot can practise. At that place are 'adhesion promoters' that volition hopefully continue the pigment from blistering off of the porcelain. Proficient luck.

Q. Hi- we accept a home built in 1904 with original claw foot tub. It is in fantastic condition but there is rust around the filter for the drain. I don't have any manner to plug the tub and so that I could soak it with hydrogen peroxide [as described in topic 8229]. Is there a paste recipe for this I could apply? I demand to take something sit on the rust ring I recall! Assist! Thank you!

A. Hi Sue. I'm pretty sure you lot could thicken hydrogen peroxide with fumed silica (the powder/fluff you see for that purpose in epoxy filler kits). Only whether any household production like cornstarch or flour or blistering soda can be used without consuming most of the oxidizing power of the peroxide, distressing, I don't know.
