How should transition areas around beams be treated?

Transitions around beams must be treated to keep a continuous fireproofing layer. The fireproofing system is rated as a whole, so where beams meet slabs or decking, any gap, thin spot, or discontinuity can become a weak point that heat and flames could penetrate. To prevent this, apply coating with continuous coverage across the transition and maintain the specified overlap and thickness where the beam edges, flanges, and adjacent surfaces meet. If the surface geometry creates voids or misfits, patch them as needed to restore the required thickness and ensure proper adhesion, using the same fireproofing system per the project spec. Leaving gaps or relying on spray alone without proper overlap can compromise the rating, and using a different material can create compatibility issues.
