Do-it-yourself fireplace repair. Average and current repair of the furnace

Do-it-yourself brick oven repair in the country is quite real. Is it possible to give a second chance to a heating stove, which stood in the country for ten years without major repairs and was the only source of heat for the country house. In principle, you can. Here we will introduce you how you can repair a brick oven without the cost of calling specialists. We will repair the oven ourselves!

For this you need:

1) carry out a visual inspection of the oven.

2) Decide what needs to be changed.

3) Determine what else may well serve.

Today we will be dealing with the repair of a brick oven. In this case, the furnace complex, which is located on two floors of the dacha.

The secret of lining the firebox

To prevent the row of tiles from sinking down, we lay a corner by 25 mm in the groove of the masonry. Its thickness is approximately 4 mm, and this is the width of the aisle of the tiles. The door fittings will completely cover the space not covered with tiles, and the corner itself will not allow the tiles to slide. After the glue has set, carefully remove the corner from the masonry.

Here is the secret of gluing tiles - the corners are installed above the view and above the firebox.

Pay particular attention to the "synchronization" of the rows of tiles, they must go one into one from one wall of the stove to another.

Grouting

Approximately 10 - 12 hours later, after the glue has finally set, we need to grout the joints. We remove all the crosses (spacers between the tiles) and apply grout. You can use Ceresit Grout - it is heat resistant. It is sold ready-to-use, white, so that its color matches the color of the tile - add a little chocolate color to give the desired shade. We apply with a continuous method. How much you need will sit in the seams, then we will remove the rest of it from the surface of the tile.

We made a grout on the front of the stove. We wait three hours and remove the grout with a damp cloth or sponge. Everything should be easily removed from the tile surface.

Be careful. One has only to overexpose the grout on the tile, and you will no longer be able to remove it without the help of abrasives, and this, in turn, can spoil the appearance.

Installation of furnace fittings

We are proceeding with the installation of furnace fittings. We take all of it from one manufacturer, I used the Finnish company SVT. For decoration we use 50 * 50 mm Senegal porcelain stoneware steps. This is a fairly strong and heavy material, but it looks very expensive.

We finish the pipe and the top of the stove with porcelain stoneware.

The technology is as follows. We apply glue, the same as for tiles. We screw self-tapping screws into the seam of the masonry, put plates on them and then tighten everything with tape around the pipe. We leave it for a day, remove the scotch tape, check the reliability, unscrew the screws - it turned out very effectively!

The final touch. We install accessories for cooking - a hob, a firebox door and a blower. We fix everything with concrete dowels.

If we compare what was and what became, it’s hard to believe that the repair of the brick oven could bring it back to “life”!

When should the oven be repaired?

The opinion that stove heating remained only in villages is nothing more than a stereotype. The owners of new houses and cottages often use this type of heating. Folding a new stove is only half the battle; you still need to be able to take care of it and, if necessary, carry out maintenance.During long-term operation, a number of problems may arise, which can be solved either by a specialist, or, using some advice, you yourself.

Regular preventive measures will help avoid serious damage to your brick oven.

The main sign that your stove is in immediate need of repair is insufficient draft, when smoke, instead of going outside, ends up in the room.

This is not only unaesthetic, but also extremely dangerous, as it can cause burnout.

Ordering a brick oven.

What are the reasons why the stoves start to smoke? Firstly, it can be a consequence of the deposition of a large amount of soot in the chimney. Therefore, always after the end of the heating season, it is necessary to clean all outlets and pipes from excess deposits. Secondly, thin masonry walls can remind of themselves. From extreme cold they can freeze or damp, from which the passing gases are cooled. Cracks and crevices may also form, through which smoke seeps into the interior of the room. Do-it-yourself routine repairs can be started by preparing the necessary materials and tools:

• clay;
• sand;
• water;
• a sieve for filtering clay;
• bonding materials: cement, asbestos;
• heat-resistant glue;
• ceramic heat-resistant cord for the oven;
• masonry tools.

We repair the stove

If the stove itself has cracked, the masonry mortar is crumbled, and smoke is pouring through the cracks of the hob and the base of the stove, then measures must be taken to seal all existing cracks as soon as possible and, possibly, strengthen the brickwork. To do this, you need to remove the hob from its place, clean all the existing plaster from the side surfaces and examine how firmly all the bricks are in the masonry.

Reinforcement with wire

Strengthening the frame
If there are loose bricks, then you need to strengthen the entire base of the furnace with your own hands. On the side surfaces of the stove, a small depth is made around the perimeter of the strobe - by 2-3 mm. After that, a thin annealed wire is taken and placed in the groove made, and the stove is, as it were, tied with an iron band. Then the wire must be pulled together by twisting it in several places.

Loops are made on the wire, where any metal object is inserted, even an ordinary nail, and alternately these loops are twisted in one direction. But you need to monitor the tension of the wire and not overdo it so that it does not break.

Sealing cracks

Next, you should prepare a solution for sealing cracks. However, before that, the oven must be heated, because all such work is carried out on a warm surface. All surfaces in need of repair are cleaned of soot, dirt, old mortar and rinsed with water to remove soot residues. The soot is greasy and the new grout may not adhere to the old surface.

Solution composition:

Greasing slots

• sand;
• clay;
• Portland cement;
• heat-resistant glue.

The sand should be taken fine, and the glue should be diluted with water in a 1: 1 ratio. First, you need to prime the surface of the oven, then seal up all the cracks with a solution. Around the perimeter of the removed hob, you need to lay a thermal insulation cord made of ceramic.

It is not recommended to lay asbestos cords, as they can release, when heated, substances harmful to the health of the surrounding area. It is allowed to replace the ceramic cord with mineral basalt wool material.

Door repair

In addition to repairing the very base of the stove, it may be necessary to strengthen the door. Usually, significant gaps form above it, and the door itself wobbles. When laying stoves on the frame of the door, strips of metal extending to the sides are welded on from opposite sides, which are walled up in the masonry. Therefore, it will not be possible to remove the door without dismantling the entire front of the oven. Yes, there is no need.You just need to strengthen it by applying a sufficient amount of new solution and installing a sealing insulating cord. But here the solution is already advised to prepare on the basis of fireclay clay with the addition of heat-resistant glue and, to a lesser extent, Portland cement. The mortar is prepared in a ratio of 3: 10: 1, where 3 parts of clay, 10 parts of fine sand, 1 part of cement. Add a little heat-resistant glue to the finished solution. The consistency of the solution should resemble thick sour cream.

Broken door

The repair area around the door should be brick-free and rinsed with water and a stiff brush to remove all clay and soot residues. After that, the surface is primed, as in the case of the repair of the side surfaces of the furnace. A heat-resistant seal is placed in all the cracks around the door and carefully sealed with mortar.

After a day, when the solution dries up, you can heat the stove with a small amount of firewood.

Independent work

Every time, as soon as it comes to the execution of construction work, each of us begins to be interested in the question of the possibility of carrying them out by ourselves. It's not about saving money, it's the elementary pride of a person who believes that he has golden hands. In order to competently combine desire and capabilities, we list the situations when you can rely on your own strength.

Good to know: How to make a fireplace with your own hands, step-by-step instructions for work

If you yourself made the laying of the fireplace, the installation of the chimney and the arrangement of the firebox, or at least took an active part in this, then a positive result is not guaranteed, but you can really assess your capabilities and quickly find the cause of the malfunction and a way to eliminate it. If from all experience there is only ignition of a finished fireplace, then it is better not to take risks and realize that only a masonry master can competently perform all the work.

If all repair work is classified, then you get three groups, which differ from each other in the complexity of the implementation and the required skill. It remains only to check which group the personal case falls into in order to prevent serious mistakes that will lead to more unpleasant consequences.

Fire in the hearth

1. The first group is light work. This work should be done by every owner of the house who has a wood-burning fireplace. If you are not ready to service the device in the slightest way, then you should think about the relevance of the installation in general. The list of works includes cleaning of chimneys, repairing cracks, replacing a grate, cleaning an ash pan, repairing doors. These works should be started on their own, since it is impractical to attract outsiders due to the simplicity of the manipulations.
2. Work of average labor intensity is often accompanied by partial dismantling of the masonry. This is the replacement of the lining, burnt-out metal products in the furnace, the installation of new bricks instead of the fallen ones, the removal of foreign bodies from the chimney. Here, each owner has two options for the development of events: calling a master who will professionally repair stoves, fireplaces, or self-repair according to a strictly defined algorithm. It is not so difficult to recognize this type of repair work. If there were no complaints about the functioning of the fireplace for a long time, and suddenly it began to smoke, melt poorly, heat poorly, then the reason is not in the design, but in temporary malfunctions.
3. And the most time-consuming work, which can only be entrusted to specialists, requires skill and experience. Moreover, if you made a fireplace with your own hands, then you yourself are a specialist, because no one knows the intricacies of the device better than you. Difficult work includes the elimination of various flaws in the design, if possible. The saddest option, when the fireplace will have to be completely dismantled, should not be ruled out.

List of some repairs

So, you decided to repair the fireplace yourself. What prompted this decision? Usually there are two main reasons, which are the disappearance of draft and the appearance of cracks on the walls of the fireplace.

Furnace restoration

• Small cracks can be repaired with plaster mortar. If a crack has formed not only in the decoration, but also in the brick itself, then a specially prepared clay solution will come to the rescue. Clay, sand and cement are mixed in a ratio of 3: 8: 1. Having brought the mixture to the desired consistency, let's start preparing the surface. The place where the crack has formed must be deepened. Then you will have to remove dust and crumbs with a damp cloth so that the solution adheres better. The resulting space is sealed with a tourniquet molded from the ready-made solution.
• Poor traction is usually caused by a fallen brick. We have two tasks: to remove the fragments of the old brick and install a new one in its place. The success of this work depends on the foresight of the stove-maker who laid the pipe. Anticipating that sooner or later the chimney will have to be cleaned, experienced craftsmen advise to make several doors for cleaning along the length of the channel. If this is not possible, then secret hatches are left, which are covered with bricks without mortar. To make them easier to find later, the bricks are not laid along the plane of the wall, but given out a few millimeters in front. After that, the chimney is finished with plaster. During cleaning, you should find the protrusions and beat off the plaster, and the desired brick can be removed with ease. The chimney access hatch is ready.

Over time, any fireplace, any stove externally changes. Cobwebs of cracks appear, the rows of masonry are shifted relative to each other. The metal walls of the hearth burn out, and condensate in the pipe has long ago provoked the development of rust.

Even with such a complete list of faults, you should not rush to disassemble the device. Many craftsmen are ready to help, this will be a real restoration of the fireplace, which will give it a second life.

The fireplace system is ready for use again

The master will replace the nodal metal parts of the furnace, strengthen the structure with screeds, which will be masked with a layer of new plaster. With this approach, it will be useful to refresh the exterior with new materials.

Good to know: How a fireplace door is made, how to do it yourself

If the fireplace initially worked incorrectly, the flame was constantly extinguished during ignition, and at any of the stages the smoke penetrated into the room, then you need to analyze the structure. In this matter, for sure, only the master will say whether it is profitable to repair the fireplace or it is more profitable to break it and build a new one, in which all the shortcomings will be eliminated.

DIY oven repair: useful tips

The brickwork of the furnace of the improved (with a stove in a pole) Russian stove: a - general view of the stove; b - 1st row, c - 2nd row; d - 7th row; 1, 3 - baking; 2nd - 1st row of the main chimney; 4 - slab ash pan; 5 — stops.

We offer you a few tips to help ensure high-quality do-it-yourself ongoing repair of the furnace:

1. Any DIY repairs, from grouting cracks to replacing bricks, should only be started when the stove is warm. That is, the stove should be heated a little beforehand.
2. You can check the plasticity of clay in the following way, if, by rubbing it between your fingers, you could not determine anything. A mixture of clay and water must be stirred with a wooden board. If the layer of clay on it is thick, then another portion of sand must be added to the solution.
3. If the appearance of cracks and the breakdown of the masonry is due to external reasons, then the stove does not require current, but major repairs in order to avoid repeated problems. Overhaul can also be done by hand, or you can turn to a specialist for help.
4. The location of the blockage in the chimney can be determined by heating the stove or by passing a wire through the doors to clean the soot. Maintenance in this case is unlikely to help you.
5. To prevent the ceramic heat-resistant cord from burning out the first time you use it, check its fire resistance at the time of purchase. Feel free to ask the seller to check it with you.

If the current repairs are not delayed, then the stove will last more than a dozen years. It will be much cheaper and easier to implement than a major overhaul - reconstruction of an old stove or laying a new stove.
