Wind and weather leave their mark on objects that are left outdoors all year round. This unavoidable process becomes particularly evident in the form of rust on zinc tanks. Fortunately, there are ways and means to make the tub shine like new again. Read more here.
If the zinc tub rusts, it is only galvanized
Rust gives an indication of the material composition
If your zinc tub starts to rust, it is probably not real zinc, it is galvanized iron tub. Real zinc is characterized by resistance to corrosion. With iron, on the other hand, a brown coating forms on the material. However, this is not just a superficial layer. The rust eats deep into the material and makes it porous. In order to continue using the zinc tub, you should act quickly at the first sign of rust:
Remove rust
- Remove the rough layer with coarse sandpaper.
- Then create an even transition to the non-rusting material.
- Apply a metal primer several times.
- Roughen up the old paint.
- For larger damage, use a sanding machine.
- Renew the entire coat of paint.
Attention: Rust can be very sharp. Under no circumstances should particles get into existing wounds. Otherwise there is a risk of blood poisoning. Therefore, be sure to wear gloves when working.
Rust doesn't have to look bad
Since not only the surface but also deeper structures of a zinc tub are damaged by corrosion, you can unfortunately no longer use the tub as a garden pond. But throw away the tub right away? If the purpose of use does not place any demands on a certain basic stability, rusty garden decoration gives your home a very special charm.
