What is the 'wet spray' process in fireproofing?

The 'wet spray' process in fireproofing refers to the technique where the fireproofing material is mixed with water just before it is applied to the structural elements. This method is crucial as it helps to achieve a uniform and cohesive application of the fireproofing material, ensuring that it adheres well to surfaces and provides the necessary fire resistance. The addition of water aids in the activation of certain chemical properties within the material that enhance its performance.

In contrast to other methods of application, such as dry spray or applying materials in extremely dry conditions, the wet spray process allows for effective bonding and consistent thickness, which are vital for maximizing fire resistance. Moreover, applying the material at elevated temperatures could compromise its integrity and performance, making the wet spray process the preferred choice for many fireproofing applications.
