How can irregular spray technique affect fireproofing?

Irregular spray technique can significantly compromise the required thickness of the fireproofing material. Achieving the specified thickness is crucial for fireproofing to be effective; it determines the material's ability to insulate structural elements from heat during a fire. When the application technique is inconsistent, certain areas may end up with insufficient coverage or varying thicknesses, leading to weak points in the fireproofing performance. If the material is too thin in some areas, it may not provide the necessary protection, thereby increasing the risk of structural failure during a fire.

This aspect directly relates to the effectiveness of fireproofing as a safety measure. Adequate and uniform thickness ensures that the fireproofing has the intended fire-resistance rating as per code requirements. Therefore, an irregular spray technique undermines the overall integrity of the fireproofing system, making it critical to adhere to proper application practices to meet safety standards.
