When you rely on structures and tanks, corrosion is your worst enemy.
Structures and tanks can protect against rust for decades—or it can fail
within a few years. It all comes down to surface conditions.
Why are Surface Conditions Important?

What Factors Affect Surface Condition?
There are 4 main factors affecting surface conditions. Understanding these are critical to learning how to avoid them.
- Humidity - Exposure to moisture, including condensation, can cause:
- Increased corrosion rates
- Curing and adhesion problems while coating
- Changes in weather - As the weather shifts, a controlled environment must be constantly adjusted to compensate.
- Temperature - Unregulated air and surface temperatures can cause:
- Condensation if the metal’s surface temperature reaches dew point
- Improper curing of coating if temperatures are too high or low
- Defects such as blistering, pinholing, cratering, dry spray and mud cracking.
- Altitude - A job site’s elevation can cause:
- 3.6° F drop in temperature per 1,000 ft.
- 1° F drop in dew point temperature per 1,000 ft.
- Condensation if both temperature and dew point are not monitored
