Brick is a porous material, and therefore moisture falls into its structure, it destroys the masonry from the inside.
Special brick processing agents provide additional protection against external influences and moisture. Such processing is needed to increase the service life of the structures that are lined with bricks. It will also help to avoid cracks, fungal deposits and deterioration of the characteristics of the structure. The compositions penetrate the brick and activate there reactions against mold and dampness.
What is needed for processing?
The weakest place in the masonry are seams. It is through them that moisture penetrates inside, and during frosts the water freezes. There it expands and acts on bricks, as a result of which the material is destroyed. Also, some types of bricks can absorb through the pores of moisture, which does not have time to dry and remain inside, as a result of which microcracks appear and chips, which also leads to destruction. To protect the brick from corrosion, experts recommend to process it with special compositions and carry out hydrophobization.
The usual protective composition consists of iron oxide, purified water and binding components that can penetrate silicate and enhance its properties. The binder in such a liquid is potassium silicate, capable of interacting with salts. It helps to improve the protective properties of ceramic products, protects them from UV impact and mold. Also protective formulations improve the view and color of the brick.
The compositions increase the stability of the wall to frosts and eliminate the possibility of the appearance of chips or cracks on them. At the same time, the stone does not lose vapor permeability.
Advantages and disadvantages
Impregnation makes it possible to protect the foundations from moisture and does not allow it to penetrate into porous structures. When processing the material, a film is formed by such a composition, which does not give to develop fungus and mold.
- preservation of the ability of bricks to pass air;
- Protection Material from a bundling, which does not allow him to lose its appearance;
- protection against cracks;
- an increase in corrosion resistance;
- environmental Safety;
- preservation of color, textures and structures of stone;
- protection against pollution and dust on the surface;
- Improving the thermal conductivity of the wall, which affects the reduction of heating costs.
The disadvantages include what makes such mixtures are not suiced, and they will also have to be applied periodically to the surface, which will require additional time and means.
Penetrating waterproofing is several types, among which you can note
- acrylic single-component;
- two-component silicone;
A biocidal impregnation for brickwork and processing the facade of houses can be different types.
Impregnation under wet brick
The so-called liquid glass for waterproofing with a wet effect consists of a silicone, which not only does not allow water to penetrate into the wall, but also protects against contamination, as a result of which the surface is easily cleaned from formations and becomes brighter. After processing the walls, they acquire stability to moisture, the effect of wet stone appears on them. The treated wall will always look fresh and moisturized, but in fact it will always be clean and dry.
Currently, such protection against water penetration is considered the most popular.
This composition is made on the basis of oil from the German concern. The mixture after applying does not leave the divorces, and also does not impair the conductivity of the material, as a result of which moisture is derived from it naturally, which protects against the fungus and from mold. Therefore, the composition does not make it possible to penetrate inside the walls of moisture, improves the color and brightness of the finishes.
Such impregnation is used both for base, walls in the bath and for the foundation.
They help protect the walls from moisture, strengthen them and are used to prevent the occurrence of bacteria and insects in masonry. The solution is stirred with water and applied to objects by spraying. It can also be added to the building mixtures at the end stage of the object.
The service life of the composition is 10 years, after which it is necessary to repeat the procedure.
The mixture from the German manufacturer improves the water-repellent properties of brick masonry, is distinguished by durability and quality. Also prevents the appearance of dust and dirt on concrete surfaces. The tool dries quickly and forms a transparent film.
Makes it possible to protect the object from all types of negative factors. Warns the corrosion of a silicate basis, increases the life of structures and prevents them rapid wear. Also protects against industrial pollution and ultraviolet, can be applied to stone, concrete, cement and other surfaces.
If there is no possibility to buy such funds in the store, they can be cooked independently. For this take vegetable oil and heated it on fire, adding Olif. Processing with such compositions is also carried out in two layers, each of which should dry out at least two days. If it is properly to prepare such mixtures, then they are not inferior in the quality of the factory, but the only drawback that you will dry will be longer.
Before using these components, it is necessary to prepare and the basis. For what you need to clean it from dirt and let dry.
Start work is necessary in a warm day. If there are already damage on the walls, they need to be seen. To do this, you can apply special tools.
In some moments, the walls of the brick will need to be protected from verbs that manifest themselves after a certain time on the surface of the brick. Such white divorces not only spoil the form of the structure, but also indicate the slow destruction of the solution and the most masonry material in the wall. To protect against verbs, various drugs are used, which differ in their composition, but before applying it is also necessary to prepare the surface.
When the first raid appears on the wall, it needs to be quickly eliminated, since mold can appear in those places. In this case, also effectively use silicon-based hydrophobizers. These compositions are used often and at the construction stage, adding them to the solution, which increases the storage resistance to frosts and improves its characteristics.
All these funds are sold in banks. One liter composition is enough for 150 square meters of foundations. To do this, you only need to produce the composition in water in accordance with the instructions and apply to the dry cavity.
Walls can be pre-degraded and treated with antiseptics. You can produce yourself independently, as it does not cause difficulties. The impregnation is applied by a thin layer on the surface and allow it to dry out for 10-15 minutes. If necessary, the procedure is repeated. Support such protection can up to 10 years.
The factor in the destruction of masonry can be the wind that will blow a solution and destroy bricks. Such destruction is not immediately, but can last decades. From the wind, high buildings usually suffer, where air flows are present, which change in temperature.
It is precisely temperature drops that can cause rapid destruction of masonry, and therefore the surface is necessary to process. It is also used for this, hydropobizers that improve the characteristics of the wall and do not give it the opportunity to collapse. To carry out surface treatment using the above tools It is necessary to stock materials and tools, including:
- compounds for mixtures;
- antiseptic means;
The better the defense of masonry from external negative factors will be made, the longer the structure will serve. All factors affecting the wall adversely affect it, and therefore it is not worth tightening with the processing process. It is necessary to produce such procedures immediately after the construction of the house. After entering the surface, the strengthening solutions penetrate into the material to a depth of 2 cm and form a thin protective layer there. It does not allow the parts of the masonry and prevents the penetration of water inside, forming a crust.
The protective layer can withstand nitrogen, nitrates and other components, and also does not allow to form on the surface of dirt or dust. Effectively operates at temperatures from minus 60 to plus 200 degrees. The solution does not leave after an unpleasant odor and safe for nature or humans. Such mixes from the surface are removed using rough processing.
Another way to protect against destruction is seams. It gives the wall not only the finished view of the brick masonry, but also prevents the possibility of entering moisture and other negative components in the seams.
After the stamps of the seams, these places are also recommended to additionally treat water-repellent mixtures that can be bought in the store or use ordinary sealant for these purposes.
How to process?
To cover the brick wall by any compositions to protect against moisture, it is necessary to prepare. You can impregnate each brick, but if there is no time enough for this, you can use sprayers. All work is carried out in a specific sequence:
- Stripping walls from pollution;
- biocidal treatment against mold and fungi;
- primary coating the foundations of the composition;
- secondary coating;
- Hydropobizer coating.
The surface of the silicate brick must be processed twice and apply a small amount of the composition so that no sublists occur. All works are produced in protective equipment outside buildings. If the compositions fall on the skin, they must be rinsed with water.
