Last year we painted the exterior of “Pet Camp”, a pet-boarding facility in San Francisco. The exterior of this building is factory painted corrugated steel, and there was a fair amount of visible rust. We needed a product that would handle the rust, without the fumes or mess of traditional “red-oxide” rust converters. We researched online and found “1 Step, The Rust Killer”, by Interstate Products, Inc. (store.interstateproducts.com). A description follows:
It quickly kills rust and neutralizes it completely. Water based “1” STEP rust converter works by a chemical reaction to eliminate rust and covers up to 500 sq. ft. per gallon.
Features:
- Non-flammable-low VOC
- Water based treatment
- Dries Clear; Approved for use on all non-food contact surfaces
- Protects against future corrosion
- Non-toxic and emits no harmful fumes
- Easy to use
- May be top coated with paint
- Eliminates and kill rust dead
I had some concern about the adhesion of this product to a factory-finished surface, and I was also crossing my fingers on the rust issue. I am happy to say that IPI “1 step” stuck just fine, and a year later it’s still holding strong, with no rust visible.
A side note: 1 step is a bit of a misnomer, as it’s best to apply two coats.
