What should be checked before starting the spray application of fireproofing?

Checking the substrate surface conditions, temperature, and humidity before starting the spray application of fireproofing is crucial to ensure optimal adhesion and performance of the fireproofing material. The substrate surface must be clean, dry, and free from contaminants such as dust, grease, or any other materials that could hinder the bonding of the fireproofing application. Adequate temperature and humidity levels are essential as they can significantly affect the curing process of the fireproofing material, impacting both its effectiveness and durability.

Ensuring that these conditions are suitable helps prevent issues such as poor adhesion, uneven application, or improper curing, which can compromise the fire-resistive properties of the spray-applied fireproofing. This proactive step contributes to the overall safety and compliance of the fire protection system being installed.

While considering workforce experience, project timelines, and material availability might be important aspects of the overall project management, they do not directly impact the quality and effectiveness of the fireproofing application itself in the way that substrate conditions and environmental factors do. Therefore, checking surface conditions, temperature, and humidity is the most critical step for ensuring the successful application of spray-applied fireproofing.
