How to make a mixture for stucco stoves
Mixtures for stucco furnaces are abundant in retail chains. The composition of the plaster for the furnace can be quite different. After all, each coating must be selected according to use cases.
For example, coal gives a higher temperature and here the gypsum composition is not suitable. Today we will consider mixtures for plastering furnaces, their varieties and rules of use. Also in the video in this article you can get answers to the necessary questions and do all the work yourself.

What is plastering done for?
Experienced builders know why plastering a stove. Such work gives the product extra strength and tightness.
Plastering furnaces is performed to improve the quality of the final product:
- High-quality finishing materials allow you to transform the appearance of the furnace, to give greater aesthetics to the details of the interior.
- The composition of the clay coating stucco stove It acts as a safety material, additionally strengthens the masonry, makes the furnace structure stronger and more resistant to temperature influences and mechanical damage.
Caution: The large temperature difference that occurs inside and outside the furnace leads to cracks and deformations, which can lead to the penetration of smoke from the heating system into the room. And such violations of the integrity of the furnace lead to dangerous situations.
Strengthening the construction with clay plaster
The most acceptable plaster mixes for stoves are made of clay. The price of the solution is not high, but in return you get a high-quality coating. But it should be said that preparing the composition is not so simple. Here it will be necessary to work hard.
Attention: Carrying out clay plaster reinforcement is a very important procedure. Proven ways to strengthen the structure over the years do not lose to modern techniques. The difference is only in the materials used and personal choice.
So:
- A popular and cheap method is the use for creating a skeleton of burlap. Also, among folk methods, straw, flax fiber, horse manure are often added to a clay solution. A more modern way is to add a tenth of asbestos. For residential use of asbestos is undesirable. Therefore, crushed fiberglass in the same proportions can be used.
- The use of burlap reinforcement by stove masters is a fairly popular method. But it has advantages and disadvantages. Burlap is not thermally stable; therefore, such a furnace cannot be overheated. But this type of raw material for reinforcement is easy to get and it can be used on already built furnaces.
- A more competent and technologically advanced method is reinforcement with the help of a steel mesh crate, but it should be introduced at the masonry stage. The mesh size up to 1 square centimeter will allow you to create the necessary coating density and avoid cracking, and the installation of a wire under the masonry will prevent the delamination of the reinforced layer. The stucco mixture for stoves and fireplaces adheres perfectly to the grid and will last quite a long time.
Types of mortar for plaster
The composition for the plaster of the furnace can be made on the basis of many components and it is of great importance. It depends on how long the new coating will last, what the appearance will be, and what is the level of heat transfer.
| Clay | The properties of this solution depend on the quality of the clay. The amount of sand depends on the clay content. To prepare the mixture, it is necessary to mix the dry components of the future coating, and then add water and clay. For greater strength, salt is often added to the solution, about 200 grams per bucket of material. |
| With lime and asbestos | To make a mixture, it is necessary to combine dry components in a deep container in certain proportions: 1 part clay, 1 part lime, 1/10 part asbestos and 2 parts sand. Then you need to pour water in small portions until the desired consistency is obtained. |
| With cement | In a deep container, 2 parts of sand and one part of clay and cement are combined. When mixing, it is necessary to introduce water into the mixture and come to the consistency of liquid sour cream. Use such a solution within an hour. |
Also, for high-quality work performance and a sustainable result, you can buy a mixture for plastering a furnace on the construction market or order goods on the Internet. But remember, ready mixes andmortar for stucco You cannot buy on the street in winter.
The solution freezes and loses its astringent properties. To perform the work, a stucco mixture is often used.
The progress of the plastering
Stucco using clay mixture (see Clay mortar for stucco: proportions) Is a technically simple but time-consuming process. For optimal results, care must be taken to ensure that fire safety requirements are not neglected.
Before starting work, it is necessary to think over the whole process and prepare the necessary inventory and building materials:
- Wood grater;
- Capacity for mixing the solution;
- Material for performing the reinforcement procedure;
- The components of the coating solution.
For the correct performance of work, the following sequence must be observed:
| Melt the stove | Such a measure is necessary to warm up all the walls of the heating system. This will allow the furnace material to expand, and the new coating will lie correctly, and will not deform when heated and cooled. The implementation of this paragraph is mandatory, despite the heat. |
| Prepare surface | Before starting work, it is important to properly prepare the surfaces. To do this, carefully rub the walls with a brush with a rough pile, this will remove dust and dirt from the surface, and will also help remove the weakened coating layer and deepen cracks in the masonry. |
| Apply clay | It is necessary to moisten the furnace walls with water and, using a tow or a washcloth, apply an even layer of a clay clay solution to the entire surface. On a hot oven, this layer dries quickly enough. |
| Perform reinforcement | When reinforcing with burlap, it is necessary to pre-prepare pieces of material of the required shape and size. Before gluing, they are soaked in a solution of clay and sand. Gluing of burlap fragments is performed from top to bottom. The technology resembles wallpapering, but it is better to do the work not by joining the rags, but with overlapping fabric with an overlap of 5 cm. |
| Apply plaster | When applying, it is necessary to adhere to a layer thickness of not more than half a centimeter, so that the total thickness of the lining is less than a centimeter. This will allow the coating to stay longer and not peel off. After the final drying of the surface, it is necessary to give smoothness. To do this, you can use a wooden grater or walk through the layers with a rag soaked in a liquid solution of clay. |
Attention: To check the quality of the work performed, it is necessary to allow the oven to dry, and it must not be heated until the layers have completely solidified.
- If cracks have formed on the surface during the drying period, it is necessary to carefully expand them with a knife to avoid clogging of air under the layer, and then wipe the defect with a liquid clay solution.
- If cracks continued to form after the final drying process, the cause may be a very thick coating layer, disturbed mortar proportions, a short period for shrinkage, improper brickwork or overheating of the stove surface.
The use of heat-resistant mixtures
Do-it-yourself furnishing of stove surfaces is possible in cases where the system distributes the heat evenly, without sudden temperature changes.
Attention: If the design was made with violations or of poor-quality materials and an inexperienced stove, then due to uneven heating and cooling of the material, as well as due to temperature jumps, the coating will crack and crumble.
- To solve this problem, you can purchase an industrial mixture for coating furnaces. Such building materials can withstand heat up to 200 degrees and are easy to find.
- A huge advantage of modern finishes is their heat transfer. It is several times higher than the best indicators of clay mixtures. The process of applying such coatings is almost identical to clay counterparts, but more practical and technological.
- So, for better adhesion to the surface, before starting work, the furnace walls are treated with a heat-resistant primer, and a steel mesh with cells up to 2 square centimeters is used as the reinforcing material.
- The instruction will always tell you how to properly prepare the composition, its manufacturer placed it on the package. Do not make large portions during cooking. If you do not have time to apply a coating to the surface, the composition quickly hardens and its use becomes impossible.
- The heating of the furnace can begin no earlier than after 3 days. For this, it is necessary to arrange a gradual heating of the surfaces. Start with low temperatures, this will allow the new coating to expand gradually and not deform.
- You can buy goods for heat-resistant plaster in any hardware store, and if additional coating properties are needed, then you can order the goods on the Internet.
The stove stucco mixture can be completely made with your own hands, this will be the key to the quality of the composition. After this, the mixture for plastering the stoves must be laid on the surface according to the rules and after complete drying it will serve for a long time. Therefore, look at the photo, select the desired composition and after that do the work slowly.
