4 Reasons Why Underground Equipment Corrosion Remains Unsolved

Did you know?

Underground equipment gets repaired in the first half of the year—

and rusts through again in the second half?

Year after year—same repairs, same rust.

So what’s really going wrong?

It all comes down to these 4 key issues:

1. Improper surface preparation—rust starts from the root

If the rust isn’t fully removed, no coating can protect it, no matter how thick

2. High humidity and salt—wrong coating choice

Underground humidity stays above 90% all year,

Some paints can't even stick in this environment,

In such conditions, only moisture-cured coatings work.

3. Overlooking gaps and inner corners

These spots collect water and rust the fastest—

yet they’re the most neglected.

4. No systematic corrosion protection plan

Just surface-level fixes won’t cut it,

No wonder it needs repairs every year.

Let’s take a look at the sample we applied three years ago — it’s still performing flawlessly.

The biggest highlight? The coating can cure even in damp environments.
