Hydrophobic coating with own hands
High humidity is the main enemy of most surfaces or structures. Mankind throughout the entire time of its existence constantly leads an invisible struggle with it. And it has long been proven that hydrophobic coating works best with it. For today, there are plenty of them, and they honestly prove their right to use.
What is a hydrophobic coating
Hydrophobic coating is the effect of non-wetting the surface moisture on which it is applied: brick, concrete, glass, stone, gypsum and so on. Moreover, thanks to it, the treated surface is more resistant to corrosive processes or the effects of low temperatures on it. Which is of no small importance for reinforced concrete or concrete structural elements.
Hydrophobic coating - a modern substance for the treatment of any surface. The main goal and task is to protect it, first of all, from the destructive effect of moisture. Available in the form of a spray or in a liquid state. Therefore, you do not need to have special skills or involve a specialist to use it. Hydrophobic coating can be applied to any surface by their own hands, strictly following the instructions for use.
Sphere of application of water repellents
Hydrophobic coating is used for processing finished products in factories with open warehouses, to reduce water absorption, improve heat resistance or frost resistance. And also before transporting it from these warehouses. For anti-corrosion treatment of the car body or other parts made of metal. Also in order to preserve the paint and varnish car. To strengthen and protect concrete, stone and other structural elements from the impact on their surface of weather changes and temperature changes, as well as high humidity.
How the hydrophobic agent works
Each hydrophobic coating has an active filler, which, interacting with the surface, forms a special very thin layer - a film. It is it that prevents the penetration of moisture through itself, creating an anti-corrosion barrier. This coating can process fabric elements, metal, glass, even in very unfavorable weather conditions prolonging their service life. The range of new and modern hydrophobic substances includes:
- compositions of wax;
- Teflon coating;
- organic substances based on silicon;
- corrosion with silicone inhibitors;
Having a unique structure and composition, the hydrophobic coating is able to penetrate deep into the pores of the surface, creating a thin invisible layer by crystallization.
Types of hydrophobic material
All products of the water repellent coating line are divided into four main types:
- special paints;
Varnishes are used to treat and protect wooden surfaces from spoilage, decay and other destructive actions, are produced in unpainted form, that is, completely without color. Lays down on the surface easily, the service life is quite large. Painted surfaces become attractive and shiny. The processing process takes place in two stages: preparation of the surface and the process of application of the material itself.
Impregnation. Used in the construction of tracks on terraces or the erection of the walls of the building. The material is applied both at the time of bookmarking and at the end of it. The use of impregnations is especially effective for porous surfaces, where, as a rule, water enters, which subsequently leads to deterioration of both the appearance of the surface and its characteristic characteristics.
Stains. The basis of this product is drying oil, which especially affects the quality of wooden surfaces and is perfectly absorbed by the latter. It is applied by roller, brush or spray method.
Special colors. Are applied for all kinds of wall surfaces. The product is easily applied to the material, odorless, waterproof and hygienic, vapor permeable and economical. The paint easily lays on a damp base. After drying, it becomes an excellent protective barrier against high humidity and its effects.
Hydrophobic and vehicle
Hydrophobic coatings for the car can be purchased in virtually any car dealer. Treated body for many years to protect it from corrosion or other contaminants, it perfectly protects the paintwork and prevents scratching on its surface. If you apply hydrophobic coating yourself with the method of polishing metal parts of the main components of the car, this will extend the life of the car as a whole.
Now these products are sold in a variety of forms. Modern hydrophobic coatings for the car are non-toxic, indifferent. And most importantly - are able to completely protect the treated surface from damage due to high humidity. Hydrophobic coating for car windows has a unique water-repellent effect. And this is a safe ride in a downpour or heavy rain.
Waterproof concrete with additives
As you know, concrete is a material that has a high water absorption coefficient, so it is recommended to additionally and specifically process it. After all, the moisture that penetrates into its surface will not only lead to shedding of the base, but also to damage its integrity. Often, a hydrophobic coating for concrete deposited on its surface, is able to completely protect it from this incident. But in some cases this is not enough, and it is necessary to change the structure of the material in order to minimize the level of porosity, making it more durable.
Advantages of water repellents
The main and indisputable advantages of these substances are:
- Light work with materials, for example, concrete. In ready-made designs, they are almost invisible.
- In the process of crystallization a light film is formed, which is capable of passing air.
- Non-toxic and do not contain substances harmful to human health, do not pollute the environment.
- The processing of these facades by the facades of buildings extends their service life.
Remember that in order to achieve the desired effect from the hydrophobizors, it is necessary to properly and skillfully take into account the nuance: each of the surfaces that will be processed by them has its own special means. And for this it is better to use either the advice of a competent person or entrust this matter to an experienced specialist. With the right approach and the right choice, the surfaces and structural elements treated will last for many years.
Hydrophobic compounds in waterproofing walls
Since the beginning of the development of architecture and construction of structures, one of their main elements is the roof. A solid roof is a symbol of building protection. And we must admit that it is she who is most exposed to natural and temperature loads. Therefore, it requires additional attention and processing. If you apply a hydrophobic coating for a stone in the construction or in the finishing of some parts of this country house with this material, the appearance of the material will always have its original appearance.
To this end, developers of water repellent coatings have created special additives. They are able to influence the density of the solution and plasticity. As a result, a concrete solution is obtained which is convenient for laying, and when dried it is a solid, durable, waterproof and low-temperature resistant product. In order to achieve this effect in concrete construction, it is necessary to use either the additives presented below or separately:
Comparative characteristics of water repellents
For the first time hydrophobic agents appeared about 40 years ago. They were based on: an organosilicon solution, which included polyhydroxyloxane, Na methyl siliconeate and Na ethylsiliconate. These substances had negative qualitative properties: low in efficiency and fire hazard. To date, they have completely disappeared from production. Modern means of this line are mostly made of polyorganosiloxane and its derivatives: polymethylhydride siloxanes, polymethylsiloxane resins, alkali metal alkyl silicates or other compositions based on the latter. These drugs are non-toxic, non-hazardous, not harmful to the environment and to the human body.
Surface and bulk hydrophobization
Surface hydrophobization is carried out by injection or by applying a substance with a brush, roller, spray. Volumetric hydrophobization is carried out by injection into specially drilled holes in the walls of the building or other surfaces. Drilling is done in a staggered manner under a slope deep down almost to the very end. Further, a hydrophobic material is introduced into these holes under a certain pressure. This method of surface treatment is considered more efficient than the first.
This is due to the fact that the denser the impregnation of the surface with a substance, the stronger is hydrophobic protection. Its properties do not lose such protection for 30 years at surface processing, and if a volumetric treatment is applied, then the entire life of the structure.
