One of the varieties of vapor-permeable one-component paints is silicate paint for interior use. Also produce and front coatings. This dye is classified as mineral. It is based on liquid glass. Due to the presence of special properties, these products are convenient for large construction works. The base is an alkali resistant component. Let's see what features these types of paints have, how to use them and what characteristics they have.
Structure
When performing the decoration in the room, universal high-quality silicate paints are used for interior work. Basis - liquid glass. Ethyl silicate is used as additives. According to reviews, this is the ideal paintwork for application on indoor walls. In some paints, various polymer components may be present (for example, silicone resin, which gives the material strength).
Silicate paints are a suspension of alkali-resistant pigmented grains. Also, the paint consists of silicate substances in liquid glass. Talc and chalk are often used as fillers. Calcium borate,
zinc white are used as a silicate
.
To give the product a particular shade, coloring pigments, which are obtained from metals, are added to it. They are in powder form. The pigment obtained from zinc and aluminum, in addition to the shade, gives the surface a strong and reliable protection against corrosion.
Ethyl silicate promotes the formation of a thin as well as viscous film on the painted surface. It has high strength and is fire resistant. Most manufacturers of silicate paints use sodium ethyl silicate or GKZH-10 for internal work. Due to this, paintwork materials may not lose their basic properties and characteristics for a long time. The amount of ethyl silicate in the total volume is 10 percent.
Features
The main purpose of silicate coatings is the finishing of surfaces made of bricks, ceramics, painting of plastered and concrete surfaces. They are also used for:
- Interior decoration.
- Painting of facades.
- Application on porous and absorbent, loose, plastic surfaces.
For planes on which organic particles are present, this product is not recommended.
Silicate paints are classified for internal work on the silicifier, which is used in the composition. So, group “A” includes materials with dry pigment. And to group "B" - compounds with calcium borate.
Specifications
The dispersion density is from 1.3 to 1.7 kilograms per cubic decimeter. By hiding power, materials are classified as second class. According to resistance to wet abrasion, the product belongs to the first or second class. The water absorption coefficient is not more than one hundred grams per square meter. The temperature range for use is from +5 to +30 degrees. Consumption is from 100 to 250 milliliters per square meter. Silicatization time is 8 hours. The price of silicate paint is about 3 thousand rubles per ten kilograms.
Benefits
The most important advantage of this type of paint is its high resistance to moisture and water. This is especially good for facade work, but no less important for interior work. With high resistance to moisture, the product also has good vapor permeability. LKM creates an almost perfect moisture balance due to a very thin glass film. Due to the same film, fungus and mold do not form on the painted surface. Indoor walls can be washed without any risk - the decorative layer will not be erased. This is a very practical material.
Dyes of the silicate group well withstand the effects of ultraviolet radiation and a sharp change in temperature. In addition, the product is highly resistant to open flames, the chemical effects of alkalis and acids. Dry paint withstands mechanical damage.
It should be noted that these emulsions differ in antiseptic properties. The painted surface is capable of self-cleaning. Due to the water-repellent barrier, the paint repels dust and dirt. Since there are no organic solvents in the composition, this odorless paint is suitable for interior use.
Due to their characteristics, these dyes are used not only for coating walls indoors and facades, but also for painting on walls and decorating stained glass panels.
disadvantages
Among the minuses, an insufficient level of plasticity can be distinguished. This prevents the paint from blocking microcracks on the surface. This minus causes certain difficulties in the application process. Similarly with alkyd coatings, these products are not recommended for use on walls and ceilings in the bedroom or living room. For these purposes, it is better to choose an odorless paint for interior use.
Another drawback - due to the strength and good adhesion with any bases, the paint is very difficult to remove. In some cases, it leaves with a layer of putty.
Kinds
Now two main groups of paintwork materials are produced. These are silicate-silicone and dispersion-silicate compositions. These two products differ from each other:
- Dispersion-silicate dyes contain about 8% high-quality acrylic, which is a binder. Due to this feature, diffusion characteristics are reduced. This is a one-component paint, which means that there is no need to prepare it before use. Simple silicate paint is a mixture of two components. This is liquid glass and powder. One of the representatives is Ceresit silicate paint.
- Silicate-silicone paints are also widely used in interior and exterior decoration. The advantage of these formulations is that they combine the best properties found in simple dispersion and silicate dyes. Since silicone resin cannot form a film, painted surfaces can “breathe”. In addition, the compositions are vapor tight and also able to provide moisture protection to the surface.
Many well-known manufacturers make such products. Among the high-quality and popular products, Ceresit paint can be distinguished.
"Cerezit ST54"
It is a silicate dispersible composition for indoor and outdoor use. A great advantage of the product is its resistance to mold and mildew, and vapor permeability. High quality material is ensured by its properties. Among them, the possibility of tinting can be highlighted. Ceresit paint has all the advantages of silicate paints.
This material is perfect for applying to a wide variety of surfaces - concrete, plaster (both regular and decorative). The base color is white, but with the help of tinting, you can get any shade. The manufacturer does not recommend applying the composition on non-mineral coatings (for example, on acrylic paints).
Tikkurila Products
This manufacturer of paints and varnishes also produces silicate products. You can select the paint "Tikkurila" for internal work, "Finngard." This is an inorganic one-component composition based on liquid glass. It can be used not only for internal work. Tikkurila paint is also used for facades. It is applied on concrete blocks, different types of plasters. The base color is white and the texture is matte. The manufacturer recommends using water as a solvent.
Another Tikkurila paint for interior work is Kiviteks. Unfortunately, it is rarely found on sale. This is an inorganic one-component dye. LKM can be applied on concrete blocks, silicate brick, plaster, silicate paint. Scope of application - external and internal surfaces. Colors are predominantly light. The texture is matte. As a solvent, ordinary water can be used.
These are professional paints for internal works. To get the perfect result, experts recommend using just such materials.
