Tea staining does not affect the structural integrity or the longevity of the material and it can be controlled.

Tea staining occurs most commonly within about five kilometres of the surf or a few hundred metres from a sheltered bay. It becomes progressively worse closer to the marine source.

However, wind exposure, industrial pollution levels and higher temperatures can create environments where tea staining might occur 20 kilometres from the sea. These same factors also increase corrosion rates of alternative metals.
