3 Reasons a Building Needs Humidity Control when Fireproofing

When applying a fireproof coating to structures, it is vital for the material to dry within a specific amount of time. While some fireproofing sprays contain chemical accelerators to speed hardening, they still produce a significant amount of moisture during the application process. Incidentally, the fire-resistant material may be more difficult to dry than drywall or cement. Without the right ambient conditions or construction drying services, a contractor may face delays and unintentionally create safety risks.

Benefits of Construction Drying Services when Fireproofing a Building

1. Prevent structural damage. Moisture damage caused by fireproofing that fails to dry properly isn’t always immediately apparent because it might be concealed under the material itself or a surface, such as a wall. The longer fireproofing materials take to dry, the more at risk they are to dripping, drooping, and sagging. Fireproofing may affect the strength and properties of building materials, such as wood and steel, depending on the type of chemical used and the material’s exposure to temperatures.
   Incidentally, the incorrect type of fireproofing material or the incorrect application may weaken building materials as temperatures rise, posing safety risks in the event of a fire. This is an important factor for a contractor to consider if there is a need to re-dry fireproofing materials using high temperatures. When applied to steel and other types of metal correctly, fireproofing may provide corrosion protection because it passivates the metal and increases its pH. In coastal environments or those that experience high levels of humidity, passivation is less likely to occur, leading to corrosion beneath the fireproofing material.
2. Reduce the risk of microbial growth. Fungus and certain pathogens are attracted to and thrive in humid environments. The longer fireproofing takes to dry, the greater the risk of microbial growth. This is an important consideration if the respective building material increases in moisture content after the fireproofing application.
3. Prevent construction schedule delays. Temperatures, humidity, and the weather have the potential to delay construction projects, especially when it affects the curing of wet materials. The success of a construction project largely depends on its quality and completion date. The success of a fireproofing application depends on its ability to dry without affecting the structural integrity of a building and risking the safety of that inside. With construction drying services, fireproofing drying times are more predictable and the project stays on schedule.
