If the furnace has already been built, then before taking on its putty, it is necessary to carry out detailed diagnostics. Most often, a trivial visual inspection of the oven is sufficient for this. When defects are found, they should be noted in some way and the preparation of the solution should be started. In parallel with this, many citizens may have a natural question: what is wrong with using a furnace with open cracks? The problem here is not only a deterioration in appearance and a decrease in work efficiency. The most important thing is that such a stove is fire hazardous.

Only a few ingredients need to be mixed to create a quality solution. At the same time, their correct selection is of great importance. In general, the formula looks like this: 1 part of cement grade 500, 2 parts of fireclay clay, 7 parts of river sand. Water should be added to the solution, after which all ingredients are thoroughly mixed. It is very important not to make the solution too thin or too thick. The composition should turn out to be plastic and fit on the surface with a thin, even layer.

The prepared composition is used to treat the entire surface. You can coat not only the damaged areas, but the entire surface of the oven as a whole. This will increase efficiency, improve heat transfer. It is important to ensure that the finishing compound is applied to the entire surface of the oven in an even layer. After completion of work, it is necessary to allow the composition to dry. This may take a day or two. It is strictly forbidden to heat the oven at this time.
