Porcelain tub reglazing in Stanton

Finished up a tub reglazing job in Stanton recently that was a little more involved than usual because we were essentially redoing somebody else’s work. This is something we run into more than you might think. A homeowner gets their tub reglazed by a low-priced outfit, the finish lasts a year or two, then it starts peeling and they call us to fix it. It’s almost always the same story underneath: the original company skipped steps on the prep, and the coating had nothing to grip onto for the long haul.

This particular tub was a porcelain-coated cast iron tub, the kind you’ll find in plenty of older Stanton homes. Heavy, well-built, the kind of tub that lasts forever if you take care of the surface. The previous reglazing had failed pretty badly. The bottom of the tub was peeling in sheets, and underneath the peeling coating we could see what was really going on: rust. Several rust spots had developed under the old finish, and once rust gets going under a coating, it lifts the coating right off the metal. That’s why the finish had failed. The previous company had either ignored the rust spots entirely or just sprayed over them and hoped for the best.

First step was sanding down the old coating. We had to get all of it off, not just the parts that were already peeling. Any old finish left behind would become a weak point under our new coating. So we took the whole bottom of the tub down to a clean base, working carefully so we wouldn’t dig into the porcelain or the cast iron underneath any more than necessary.

Once the old coating was gone, we could see the full extent of the rust. Cast iron tubs rust from the inside out when water gets through the porcelain layer, usually through a chip or a crack that wasn’t sealed. To really fix it, you have to get back to bare, clean metal. We used a Dremel tool with a small grinding attachment to work each rust spot individually, grinding out the corroded material until we were down to solid metal with no rust left behind. This is slow, careful work. Rush it and you leave rust under the surface, which means the new coating will fail the same way the old one did.

After the rust was gone, we built each spot back up layer by layer with a fiberglass filler. Fiberglass filler bonds well to cast iron, fills the void left by the grinding, and most importantly, once it cures it’s fully waterproof. That last point is why we changed our usual order of operations on this job. Normally we do all our repair work after the deep cleaning, but in this case we needed to seal those rust spots before they got exposed to any water during cleaning. Cast iron tub reglazing in Orange County almost always involves at least some rust work, and the order you do things in matters.

Once the filler had cured and we’d sanded each repaired area flush with the surrounding surface, we moved into the deep cleaning. Scrubbed the whole tub down with our heavy-duty cleaner, dried it completely, and then masked off the walls, floor, and surrounding fixtures.

Then we sprayed our bright white industrial coating in even passes. Came out clean, smooth, and the kind of glossy white that makes a hundred-year-old cast iron tub look like it just left the factory. The homeowner now has a tub that should hold up for the next ten to fifteen years, this time with the rust actually dealt with underneath.

If you’ve got an older porcelain tub in Stanton, Garden Grove, Westminster, or any of the surrounding cities, and you’re seeing the finish start to peel or rust spots starting to show through, don’t wait on it. Rust spreads. The longer you leave a chipped or rusting cast iron tub sitting wet, the more metal gets eaten away underneath, and the more repair work it takes to bring it back. Catching it early means a straightforward reglazing job. Letting it go for years means we’re rebuilding the surface from scratch like we did on this one. Either way, the tub can almost always be saved.
