What is the minimum allowable temperature during TFIFRM curing?

Explanation:
Curing cementitious fireproofing relies on hydration reactions that require a certain level of warmth to proceed effectively. Keeping the material above a minimum temperature ensures it hydrates properly, develops bond, and reaches the intended strength within the specified curing period. For TFIFRM curing, the minimum allowable temperature is 50°F. At lower temperatures, such as 40°F, curing can be too slow or incomplete, leading to reduced strength, poor bonding, or microcracking. Temperatures higher than 50°F are fine and may even accelerate curing, but the question asks for the minimum. Always follow the product data sheet for the exact curing window and protection requirements.
