Silicate paint: composition and properties

Today the building materials market offers a wide variety of paints for different applications. They differ in weight characteristics. Therefore, it is important to understand the advantage of a particular type of composition. The final result of the work depends on it.

One of the popular varieties is silicate paint. It belongs to the category of vapor-permeable compositions and is made on a mineral basis. This type of paint will be discussed further.

general characteristics

Silicate facade paint and compositions for interior work are used to protect various surfaces. Most often, this product is used for brick, concrete foundations. The scope of application of this paint is extensive. It can be used in fairly dusty conditions.

Ceresit silicate paint

So, the main area of ​​application of silicate paintwork compositions is the design of building facades. On sale are varieties that are designed for interior work.Also silicate varieties of paints are used in the process of marking on the roadway.

This one-component composition, which is made on a mineral basis. Moreover, this type of paint is truly universal. It is produced in the form of a one-component composition. Relatively low cost and special characteristics make silicate paint for the facade and interior popular among domestic buyers.


Silicate paint is made on the basis of liquid glass. Ethyl silicate is added to it. Also may include some special polymers. These include silicone resins. They increase the strength of the composition after curing.

Silicate paint for interior work

To paint got the desired shade, it adds special pigments. They are created in powder form and are made from various metals. If the composition includes pigments based on zinc or aluminum, the composition acquires pronounced anti-corrosion properties.

To the consistency of the emulsion was appropriate, add talcum, mica, chalk and other similar fillers. Ethyl silicate promotes the formation of a thin film on the surface, which, after solidification, becomes resistant to mechanical stress.Also, the paint is not subject to burning, retains its original qualities for a long time precisely because of ethyl silicate. This component should be 10% in a quality product.

Application area

Silicate paint has a specific scope. This composition is suitable for limestone surfaces, cement type. Paint can be covered with cement-plaster walls. This composition is widely used in the restoration of various buildings, including historical monuments.

Silicate paint

If the surface of the finish has crumbled or has lost its aesthetic appearance, this type of paint is best suited. It will provide reliable base protection from the adverse effects of weather conditions. Inside the premises in such a composition is covered with brick, concrete and plastered walls.

Silicate varieties of paints are forbidden to be applied to the surface of natural wood, materials that were made on the basis of plastic (PVC, polypropylene). Also, it is not allowed to apply the silicate composition on the stone, which contains resins, bard or other organic components.


Today silicate paints Ceresit, Caparol, Kreisel, etc. are very popular. Their cost ranges from 3 to 5 thousand for a capacity of 5 liters. At the same time, commercially available compositions can be of two types. The first group includes silicate-silicone compositions, and the second - dispersion-silicate paints. There is a significant difference between them.

Facade silicate paint

The second group of paints contains up to 8% acrylic. It acts as a binder. In this case, the diffuse characteristics of the paint are somewhat reduced. This one-component composition, which is completely ready for use.

However, silicate-silicone resins have a certain advantage. The film, which is formed after their deposition on the surface, is characterized by vapor permeability. At the same time the surface is reliably protected from the adverse effects of various weather conditions. This group of paints can be two-component.

Recommendations for selection

There are many varieties of silicate-based paints on sale. They differ in technical characteristics and a scope. Silicate paint ST-54, produced by Ceresit, is the most popular. The cost of this product is 4.4 thousand rubles. for 5 l.Also in demand paint "Caparol". Its cost reaches 5.5 thousand rubles. for a capacity of 12 liters.

Silicate paint ST-54

When choosing a composition, you need to pay attention to its wear resistance class. The most resistant to abrasion is the class E1. It is practically impossible to wash a layer of paint class E5. The first category is for facades. Class E5 can only be used in dry, clean rooms.

The density of the composition directly affects its consumption. More liquid formulations are spent more economically. Also on sale are paints that can be applied from 1 to 4 layers. The lower the grade, the less layers need to be applied to obtain the desired shade. It is better to give preference to products of class 1.

Application features

The application of silicate-based paints does not cause any particular difficulties in both interior and exterior finishing. The surface before processing must be treated accordingly. The consumption of silicate paint in this case will be less.

Silicate paint consumption

First, the old layers of plaster or paint must be thoroughly cleaned. Then the surface of the wall is coated with a water-based primer. When applying the paint, the ambient temperature should not be less than + 5ºС. Walls after applying the composition must be protected from direct sunlight and moisture.

Depending on the type of paint it will have to be applied in several layers. The average consumption is 0.3 l / m². In the process of applying paint to protect the skin of the hands. To do this, wear rubber gloves. Also, you can not store a can of paint in a place accessible to children. It should be hidden in a dark, heated room.


Silicate paint for interior and facade type has a lot of positive qualities. This makes it popular in the building materials market. It should be noted the high resistance of the layer after solidification to moisture. Also, the sun's rays do not affect the appearance of the paint. Silicate compounds are not afraid of temperature changes.

Silicate facade paint

The presented kind of structures differs in the long term of operation. They do not fade, do not crack. Therefore, such compositions compare favorably with lime based paints.

Silicate compounds are resistant to different chemical compounds. This quality is relevant for large cities. Here precipitation containing acids and other chemical elements falls, smog constantly appears. Silicate-based paints are not afraid of such effects.

Another important quality of the presented product is resistance to biological effects. The surface covered with such a composition is not covered with fungus. For insects, bacteria, microorganisms, it is impossible to penetrate the barrier of such paint.


Silicate paint has a lot of positive qualities. However, it is not without flaws. They should be considered before applying a similar composition. Paints of this group are classified as toxic substances. They are unsafe for humans and the environment if used improperly.

In the process of working with paint, it is necessary to provide for high-quality protection of the skin, eyes, respiratory tract from ingestion of this composition. This product is also incompatible with materials from plastic, natural wood. Therefore, the range of its application is limited. After applying the paint can not be washed off by any means. The surface is cleaned exclusively by mechanical means.

Having considered the features possessed by silicate paint, we can note a lot of its advantages. Such a product, even with some of its flaws, is popular among Russian buyers.
