What is the best practice to install monolithic products in cold weather?
Question :
What is the best practice to install monolithic products in cold weather?
During cold weather, the refractory lining and the applied surface should be kept at a temperature above 50°F (10°C) during application, curing, and right before the start of the dryout/heatup procedure. Cement bonded castable must not be exposed to freezing temperature (below 32°F / 0°C) during the installation and initial curing phases). If exposed to freezing temperatures during storage, dry monolithic products should be heated to a temperature between 50°F (10°C) and 80°F (27°C) prior to installation for best results. Measure material temperature for best results. An immersion thermometer is a good method to measure the refractory monolithic temperature
