What is a consequence of not preparing the surface adequately before fireproofing?

Not adequately preparing the surface before applying fireproofing can lead to poor adhesion and performance of the fireproofing material. Proper surface preparation is crucial as it ensures that the fireproofing product can bond effectively to the substrate. If the surface is contaminated with dust, grease, dirt, or any other foreign materials, this can disrupt the bond between the substrate and the fireproofing application.

When adhesion is compromised, the fireproofing material may not achieve its intended thickness, coverage, or operational integrity, which can severely hamper its ability to provide effective fire protection. This can lead to greater risks during a fire event and potentially higher costs in the long run if the fireproofing needs to be reapplied or if the structural integrity is compromised due to inadequate fire protection.

Other options, such as improved adhesion, lower costs, or longer curing time, do not accurately reflect the consequences of poor surface preparation and fail to emphasize the critical role that proper groundwork plays in the overall effectiveness of fireproofing materials.
