Walk-in Freezer Floors: The Best Thermal Shock Resistant Coatings

The Importance of Proper Floor Coating in Freezer Environments 
 A walk-in freezer's floor needs to withstand extreme temperature fluctuations, making it crucial to choose the right material. In this project, the owners of a walk-in freezer were facing repeated failures with epoxy coatings, which couldn't handle the thermal shock from rapid temperature changes. They turned to a more durable solution with MORTARTHANE™ HF and MORTARTHANE™ TC, a trowel-applied urethane cement system designed specifically for environments subject to hot and cold stress. 

Step-by-Step Installation of the Thermal Shock-Resistant Coating 

  1. Preparation and Cleanup 
     The floor was prepared by cleaning and ensuring a smooth surface. This step is critical for ensuring the urethane cement bonds properly and performs effectively. 
  2. Applying the Urethane Cement Base 
     MORTARTHANE™ HF, a ¼-inch trowel-applied urethane cement, was applied to form a solid foundation for the floor. This product provides a tough, durable surface that can withstand extreme temperature swings. 
  3. Topcoating for Extra Durability 
     The floor was then topped with MORTARTHANE™ TC, a urethane cement-based topcoat that adds additional protection and ensures longevity. 
  4. Coving Mortar for the Edges 
     MORTARTHANE™ coving mortar was used to create a seamless, watertight edge along the walls. This "bathtub" effect helps prevent leaks into areas below the freezer. 

Why Urethane Cement is Ideal for Freezer Floors 

  • Thermal Shock Resistance: MORTARTHANE™ HF and MORTARTHANE™ TC are designed to handle drastic temperature changes, ensuring the coating won’t peel or crack under stress. 
  • Waterproofing: The seamless application prevents moisture from leaking, safeguarding the structure beneath. 
  • Long-Lasting Durability: Unlike epoxy, these urethane cement coatings won’t pop off in extreme conditions, ensuring a long-lasting solution.
