On a flute deck, how many measurements should be taken in a 12 in² area?

For measuring the thickness of spray-applied fireproofing on a flute deck, best practices recommend taking a total of four evenly spaced measurements within a designated 12 in² area. This approach is crucial to ensure that the thickness is adequately representative across the entire area being assessed.

Taking four measurements allows for a more comprehensive understanding of the average thickness and accounts for any variations that may occur due to application inconsistencies. By spreading the measurements evenly, you minimize the risk of isolated anomalies skewing the results and can better ensure compliance with fireproofing standards. This systematic method aligns with widely accepted industry practices for achieving accurate and reliable assessment of fireproofing applications.
