Advantages of ready mixes

Heat-resistant mixture "Terracotta" is a dry mortar that is intended for laying objects that will subsequently be subject to heating. This solution is manufactured using classical furnace technology. The composition of this mixture includes kaolin clay, dried and crushed, as well as chamotte (ceramic) crumb. The temperature that this mixture withstands is 1300 degrees Celsius. It is important to know that the mortar gets strength only when it is fired. And this means that after the completion of all masonry processes, you must wait 48 hours. After this period, it is necessary to melt the furnace by 70-80% of its full filling and maintain the combustion process in this state up to 5-6 hours. In order to avoid such inconvenience, like shedding the mixture after masonry, experts recommend carrying out decorative plastering or facing the furnace.
