Dehumidification for Painting and Coating

The key to success in any large-scale painting or coating project is adhesion. Because the goal is a smooth, long-lasting relationship between the film you are applying and the surface you are working on, the real work of a project like this is in ensuring the environment allows for optimal traction.

One thing that continues to get in the way of too many painting and coating jobs is moisture. Among other disastrous outcomes, moisture in the air of a painting or coating environment can cause:

● Surface condensation, which can lead to peeling;
● Flash rust, immediately after blasting;
● Rust bloom, which leads to blistering; and
● Peeling and delamination over time.

Taking the time to prepare the surface you are working on is essential if you want to prevent these and other failures. However, it can seem that no amount of time is adequate to ensuring a perfectly dry, receptive surface. That is because condensation on the surface originates in the air.

The number-one cause of moisture on a surface is high atmospheric humidity. Moisture in the air adheres to a colder surface in the form of tiny droplets. Removing this moisture from the room you are operating in is the most effective way of guaranteeing your surface is prepared for perfect adhesion.

A dehumidification system will do the work for you, saving you time and money by eliminating moisture from the painting or coating process. There are two types of dehumidification systems:

• A desiccant-based dehumidification system passes streams of ambient air over a chemical, such as lithium chloride or silica gel, which absorbs moisture directly from the air as it passes. The chemical is heated, so that it dries and continues to absorb moisture in a continuous cycle. Because of this regeneration procedure, a desiccant-based system tends to require a great deal of power to run.

• A refrigerant dehumidification system guides moist air over cooling coils that evaporate its levels of condensation. The air is then directed over a series of condenser reheat coils, which serve to increase its temperature and reduce its humidity. This system is best for environments where the external air is relatively warm and high in humidity.

Among other benefits, a commercial dehumidifier can:

● Allow you to regulate the humidity of the room to prevent condensation;
● Prevent the buildup of dangerous and flammable vapors indoors;
● Ensure a quality coating every time, when adhering to paint manufacturer’s specifications;
● All you to schedule a coating for any time of the year, in any weather, and plan accordingly; and
● Reduce the time and costs involved in the project as a whole.
