Impact of Condensation on Construction Quality

In environmental condition checks before polyurea application, one requirement is that the substrate temperature should be at least 3 °C higher than the dew point temperature. Many people tend to overlook this rule, which can lead to various problems without understanding the underlying cause. Today, let’s talk about what condensation actually is.

What is condensation?Condensation refers to the phenomenon where moisture forms on the surface of an object when its temperature is lower than the surrounding air’s dew point temperature. From this, we can see that the essential conditions for condensation are: humidity + temperature difference.

Recently, humidity levels have been high in many regions across the country. When combined with relatively low substrate temperatures, condensation may occur. If a layer of moisture condenses on the substrate surface, it’s easy to imagine the problems that could follow.

Therefore, polyurea application must be carried out strictly according to the requirements, ensuring that environmental conditions are suitable before starting construction to avoid engineering failures.
