Question :
What is the best practice to install monolithic products in hot weather?
During hot weather, the refractory lining and the applied surface should be kept at a temperature below 95°F (35°C) during application, curing, and right before the start of the dry-out/heat-up procedure. Cold or cool water should be used when installing in hot weather. The installation equipment and installation area should be shaded from direct sun exposure. Installation at night should be considered. In hot weather conditions, dry monolithic products should be placed in shady, cool areas; out of direct sunlight. Measure material temperature for best results. Refrigerated truck vans have been successfully used to cool dry monolithics to within the ideal temperature range prior to installation.
