How to brick an iron stove: choosing a mortar for masonry and bricks, laying brick rows, cleaning masonry from mortar


The process of lining a bath stove A steel or cast iron stove is an opportunity to quickly and inexpensively equip a bath with a source of heat and steam. But it often looks unpresentable, and it is not safe to use.
Brick in this respect is much better, but it is difficult to fold it on your own, and it is expensive to pay a specialist. You can choose the best compromise option: metal + brick. It will be cheaper, since it is realistic to impose a brick on a metal stove with your own hands.

How to do it correctly, what requirements to fulfill and take into account the nuances, this article will tell.

The advantages of such a solution

A metal oven heats up very quickly, but no less quickly and cools down. In order for the temperature in the bath to be comfortable, it must be constantly heated during washing. And this is an extra consumption of firewood or other fuel.

In addition, the heat from the hot metal is too dry, and it is easy to burn on its surface and cause serious injury.


Hot metal walls are a common cause of burns

But if the iron stove is overlaid with bricks, these disadvantages disappear, but significant advantages appear.

Namely:

  • Long and uniform heat release, as the heated brick cools slowly;
  • Reducing fuel costs, the price of which is of particular importance if the stove heats the house and is heated daily;
  • The heat from such a furnace is not sharp and scalding, but soft and pleasant;
  • It's much safer to be around her;
  • Lined potbelly stove looks much more aesthetically pleasing;


Homemade stove stoves made of ferrous metal are especially in need of finishing

  • It is much easier to overlay a metal stove with a brick than to fold a fireplace with a chimney, and it will cost less.

What can be used to overlay the stove in the house?

Most often, stove screens are made brick or metal... These materials are available and do not require specialized equipment.

For masonry take refractory brick: ordinary red or clinker... Silicate is not suitable. The material is bonded with an earthen solution (sometimes with the addition of cement or lime) capable of withstanding high temperatures without destruction.

It is better to choose from metals stainless steel... She is not afraid of dampness and does not emit harmful substances when heated, like galvanized. For attaching to the walls of the room, it is advisable to choose polished sheets, not matte... Then the heat rays will be reflected from the surface. This will reduce the heating of the walls and the room temperature will rise faster.

Materials and tools

When deciding how to properly lay a brick on an iron stove, first of all you need to decide on the materials suitable for this. They must have special characteristics.

Brick

The main material for facing must be of high quality: no voids, with high heat resistance and fire resistance.

There are two options to choose which brick to lay over the iron stove in the bath:

  • Clay brick. It is used for cladding the body, masonry of the firebox and chimney of a wood-burning stove. It happens as an ordinary, front, with a decorative front surface.

  • Refractory fireclay bricks. Withstands temperatures up to 1800 degrees. It is recommended to use it for masonry and cladding of coal-fired stoves.


Fireclay brick

Advice. If the appearance is not so important, a brick, which has been in use, cleaned of mortar is also suitable for cladding.

The approximate amount is calculated depending on the method of masonry (half or quarter brick) and the perimeter of the cladding. This takes into account the dimensions of the furnace itself and the distance between it and the lining. The amount required for the construction of the site is also added here, since it is possible to impose a brick on a metal furnace only on a solid foundation.

For reference. Facing a quarter brick will be cheaper due to material savings. But it is difficult to carry out such masonry, and the efficiency of thin walls is much lower.

Solution

The ideal masonry mortar is made from clay and sand in specific proportions, depending on the quality of the clay. Without experience, it is very difficult to do it. Therefore, it is best to buy a ready-made refractory mixture based on red clay.

Before you impose a brick on the cast-iron firebox, you just need to dilute it with water, as required by the instructions on the package.


Heat-resistant mixture Terracotta

In addition to brick and masonry mix, masonry mesh and refractory sheeting may be needed to create a protective shield for wood surfaces. And also roofing material as waterproofing.

Instruments

Tools to do this work will require the following:

  • Solution container;
  • A trowel for his set;
  • Hammer for adjusting bricks;
  • Pickaxe for dividing them into parts;
  • Joining for seams;
  • Ordering - a rail with divisions applied to it, the distance between which is equal to the height of one or more rows, taking into account the thickness of the seam;
  • Building level and plumb line for level control;
  • Cord to control the evenness of horizontal rows.


Necessary tool for masonry
Also, a sponge or rag and a bucket of clean water will not interfere to remove the solution from the front surface of the masonry.

Arrangement of the foundation for a metal furnace

Before laying a brick on the unit, you need to well prepare and strengthen the base under it. Since metal structures are lightweight, they do not need a separate foundation for the furnace, but the brick cladding will have an additional load equal to tens of kilograms.

Not every floor covering can support this mass. For this reason, before laying a brick on the boiler, it is imperative to disassemble the floor and equip a separate foundation - columnar or monolithic.

Most often, a monolithic base is made. To do this, they dismantle the floor under the stove. The parameters of the foundations should be such that a gap of 10 to 15 centimeters remains between the future brick cladding and the metal body of the unit.

First, a hole is dug about 30 centimeters deep, rubble and sand are poured onto the bottom, tamped, reinforcement installed and poured with concrete. The foundation will harden for about 2 weeks.

For arranging a columnar foundation, pillars are installed at the corners of the facing box and in places of the highest load. The advantage of this base is that no drainage or waterproofing is required.

The sequence of actions during the construction of a columnar foundation is as follows:

  1. Markings are made at the corners of the oven for mounting pillars.
  2. Dig holes located strictly vertically, having a depth of about 50 centimeters.
  3. A 10-centimeter layer of sand is poured onto the bottom of all the pits and tamped down.
  4. A mortar is prepared from cement and sand in a ratio of 1: 2, it should have the consistency of thick sour cream.
  5. The solution is poured over the sand layer in a 10-centimeter layer. Crushed stone or brick chips are added to it.
  6. After hardening, brick pillars are laid out so that they rise 7-10 centimeters above the floor.
  7. Install a bar of the lower strapping. The most reliable way will be to lay the channel around the perimeter and weld the edge.

The use of concrete posts is allowed. You can make sure they are vertical with the help of a building level.

Cladding

Before laying a brick on a metal stove in a bath, you need to prepare for work.

Preparatory activities

Laying can only be started after the concrete and brick base has dried. A metal stove is installed on it, and the markings of the future cladding are made around it.

But first, it is necessary to install a fire-resistant shield made of any fire-resistant materials on the wooden walls around the hearth.


Insulation of wooden walls and floors with minerite

If you decide to prepare a masonry mortar from clay, then you need to fill it with water for several days, and sift the sand thoroughly. Since it is difficult to lay a brick on an iron stove, and it is difficult not to stain its body with a solution, before starting laying it should be protected with paper, cardboard or film, fixing them on the walls with adhesive tape.

So that the water from the solution is not absorbed into the brick, it is soaked in water about half an hour before starting work.

Masonry

When deciding how to brick a cast-iron stove, it is better to choose a masonry in half a brick. A thicker screen will take longer to heat up, and a thinner one will cool down faster.

  • The laying of the first row begins from the far corner, laying a whole brick. It is very important to lay it out evenly and neatly, since all subsequent rows will be equal to it.
  • They are laid out alternately, with an offset of half a brick. Do not jump over the row, first lifting the corners and then filling the space between them.


Laying is performed with an offset

  • The permissible thickness of the horizontal seam is 8-10 mm, of the vertical one 3-5 mm.
  • The seams are completely filled with mortar, its excess is immediately removed from the surface with a trowel.


Bricks that go beyond the plane are knocked out with a hammer or mallet

  • During the masonry process, you need to constantly monitor the verticality of the walls and corners using a plumb line or a building level.


A string stretched along the upper edge of the row will help to lead the row strictly horizontally

Advice. You can install flat bars in the corners of the future structure, spreading them between the floor and the ceiling. They will serve as a guide for the corners, and the cord stretched between them can be moved higher with each row.


Auxiliary uprights make your work easier

  • To strengthen the masonry, you can put a reinforcing mesh into the seams every two or three rows.

  • Also, every two or three rows, you should embroider the seams until the solution has lost its elasticity, and wipe the surface from the remains of the solution with a wet rag.


Sewing seams

  • When laying out the walls, it is necessary to leave ventilation holes in them: at least two on top and two on the bottom. Cold air will enter the lower ones, protecting the stove from overheating, and through the upper ones, heated air will come out.

  • Alternatively, you can revet the oven with bricks laid in a checkerboard pattern with holes between all adjacent elements.
  • Around the doors of the firebox and ash-pan, the masonry should be carried out taking into account their full opening.


The brick will have to be cut if it interferes with the opening of the doors

  • Where to finish laying is up to you. If you have a stove with a stove or a stove, it is only brought up to the top of the cabinet. You can lift it up to the ceiling. And you can make curly masonry with a vault and lining of the chimney, turning an ordinary potbelly stove into a kind of fireplace.

Types of protective screens for ovens

For air movement and better heating of the room, the protection is located a few centimeters from the walls... At the bottom of the structure are made clearances: gaps are left for this in brickwork, metal sheets are installed on legs.

Reference. When using brickwork, the room warms up more slowlybut comfortable temperature lasts longer.

Such screens are placed on the sides facing the room. And to protect walls, especially wooden ones, their sheathed.

Important! Side and front screens are used only for metal stoves. Protection of nearby walls is also needed for brick structures.

The size screens depends on size and power ovens. The material chosen also matters. At the same time, they make the necessary gap between the screen and the stove, otherwise it will overheat.

Metal

Metal protection is installed at a distance not less than 1-5 cm from the stove itself. The distance to the wooden wall should be not less than 38 cm.

If the screen is mounted directly to a wall, you must isolate her from the outgoing heat. Then the following scheme is applied:

  1. At a distance of about 3 cm fits from the wall thermal insulation layer... To have a gap, the material is not attached directly to the wall, but through slats or metal pipes.
  2. Over it installed metal protection.
  3. The screen is made so that it is taller and wider than the stove by a meter.

Advice. The air gap allows additional cooling.

There should also be a small distance between the floor and the screen. Protection is broadcast on the wall 3-5 cm from the floor... For floor mounting, the screen is mounted on special legs. Another option is to make holes at the bottom of the sheet.

Brick around an iron stove

As a rule, masonry is carried out in half a brick... This provides sufficient protection, while at the same time does not interfere with heating. Sometimes other options are used. When laying in a quarter brick, the protective properties are reduced, and the heat becomes less soft, but the room warms up faster. But the distance to the walls must be greater than the minimum.

If the masonry is thicker, in a whole brick, the room will take longer to warm up. But this shield becomes a heat accumulator, that is, it gives off heat after burning firewood.

Dimensions (edit) calculated as follows:

  1. The screen height should be 20 cm more stoves. The masonry along the wall is sometimes brought up to the ceiling itself.
  2. Distance from the stove to the edge of the shield should be 5-15 cm.

For cast iron stove

Cast iron occupies an intermediate place in terms of heat-conducting properties. It heats up worse than steel, but better than brick, and cools down, respectively, longer than the first and faster than the second. Therefore, the protective screen is installed according to special rules. For him a brick placed on the side, that is, the wall extends into a quarter of a brick. In this case, less material will be required, otherwise the technology remains the same.

Options for bricking an iron stove in the country

An iron stove is an excellent heating agent that gives comfort and coziness to the cottage. How to impose a brick on an iron stove in the country and give it a beautiful appearance? More on this later.

Read in the article

The iron stove is a heating unit characterized by strength, versatility, light weight and one-piece construction. It can be metal or steel, cast iron, chamber, channel and bell.

Metallic

A metal furnace is usually created from ordinary steel. This material is able to withstand a stable temperature of four hundred degrees. With short-term kindling, this figure can grow up to six hundred degrees. The steel model is four millimeters thick.

It is worth noting that there are devices that are distinguished by long-term fuel combustion. Their housing is not exposed to heating, and the heat transfer is at a high level due to the use of thermal storage devices.

It is not uncommon when a metal furnace is created from heat-resistant steel. The minimum metal thickness is three millimeters. This reduces the weight of the product. The efficiency is 80 percent, and the service life is about twenty years.

Note! Such devices are safe, efficient and easy to install. They are chamber, channel and bell-type.

Cast iron

A cast iron stove is another type of metal models, which in terms of strength is not inferior to a steel one, but at the same time, in terms of heat capacity and fragility, it can be compared with a ceramic model. The thickness of the product is from six to twenty five millimeters. Attention! With a thicker layer of material, the expansion from temperature will be so great that the stove will be damaged.

Note! The efficiency of the cast-iron model is high, but it is realized only when the housing area is not more than 60 square meters.
