Silicate paints for the facade: description, characteristics, rules of use

Silicate paints are an excellent option if you want to protect and improve the outside of your house. These paints, which are well-known for their resilience and breathability, have become more well-liked due to their distinct chemical makeup. Silicate paints provide a strong, long-lasting finish by chemically bonding with mineral surfaces such as masonry, stone, and concrete.

The mineral makeup of silicate paints is one of their unique qualities; it enables them to create a robust, weather-resistant surface while still allowing water vapor to pass through. Breathability lowers the chance of mold growth and long-term structural damage by preventing moisture buildup behind paint. Because of this, silicate paints are especially well-suited to regions with fluctuating humidity levels.

Silicate paints, when applied properly, provide remarkable UV resistance and color retention, keeping their vivid appearance even in direct sunlight. Their inorganic pigments guarantee a smooth finish and consistent color distribution by offering superior opacity and coverage. For homeowners hoping to preserve the visual appeal of their facades over time, this makes them the go-to option.

It’s important to use application methods appropriate for the silicate paint’s particular formulation when using it. Usually, they are made of two parts: finely ground mineral pigments and a liquid potassium silicate binder. To guarantee the best possible adhesion and performance, the surface must be properly primed and cleaned. Comprehending these principles of application guarantees that silicate paints fulfill their complete protective and aesthetic advantages.

Characterization of silicate paint

Silicate paint is appropriate for adorning concrete and brick walls. Since silicate is impervious to dust, building facade components frequently cover them. Additionally, the material is frequently used in road segment designations.

The primary ingredient in the paint formula is a unique liquid potassium glass. Other fillers used in this coating:

• mineral pigments;
• ethyl wishes;
• silicon;
• zinc;
• aluminum.

Paints that have metal particles in them are referred to as anti-corrosion. The primary ingredient in silicates is potassium glass, which gives the coating its unique strength. Furthermore, the following highly crushed, alkalis-resistant mineral pigments could be included in the composition:

• chromium oxide;
• Bordeaux;
• umber;
• azure;
• Croen of lead.

Prior to beginning painting, a solution of liquid potassium glass is mixed with a dry base containing pigments. Paint packaging consists of two containers: a separate glass container containing potassium and paper bags containing pigment. Glass in liquid form has a density of 1.41 g/cm^. Following the application of LKM, the facade does not form condensate, allowing air to freely flow through the wall.

If you apply silicate paint—such as acrylic or alkyd coating—to a wall that has already been painted, issues could occur. Consequently, professionals recommend thoroughly cleaning the wall surfaces before applying silicate paint.

Silicate paints for the facade are a modern solution known for their durability and breathability. These paints are composed of potassium or sodium silicate binders mixed with inorganic pigments, making them highly resistant to weathering and UV damage. They bond chemically with mineral surfaces like concrete and masonry, forming a strong, long-lasting coat that allows the facade to breathe. Silicate paints are eco-friendly, as they do not contain organic solvents and are vapor-permeable, preventing moisture buildup and mold growth. Proper application is crucial, requiring a clean, dry surface and specific primers for optimal adhesion. Understanding these characteristics and application rules ensures silicate paints effectively protect and enhance the facade, maintaining its appearance and structural integrity over time.

Differences from other facade colors: areas of application

Silicate is a good paint for brick and concrete walls when compared to other facade paints. For instance, because acrylic paint has little density and application flexibility, it will not be able to handle such a surface.

Applying silicone paint to mineral paint or mineral surfaces is advised. Its primary characteristics stem from the presence of liquid glass in a silicate colorful basis.

• reliability;
• strength;
• increased levels of adhesion;
• passes air and steam;
• waterproof;
• durability;
• Has UV filters.

Vinyl and lime compositions are available as facade colors. Because of its drawbacks, experts advise against using a colorful emulsion vinyl base for the facade. It has poor resistance to mold, various fungi, chemicals, and damage even though it has good resistance to steam. The composition of lime is poorly precipitation resistant. The majority of the time, lime paints are used for cultural monument restoration.

The silicate and silicone facade paint are similar in a few ways: they are both intended for various surfaces and can frequently be applied over brick and concrete. Furthermore, these colors don’t require the use of extra antiseptics. Silicone or silicate facade paint costs more than acrylic.

Pros and cons of silicate paint for the facade

The primary benefit of silicate paint is its exceptional resistance to moisture, which is especially useful when painting external facades. A painted wall will not develop mold or fungus because of a thin layer of glass protective film. Silicate coloring base paint is washable and does not fade on surfaces. service life of the coating up to 20 years.

Paints made of silica are resistant to fire, UV rays, and all types of weather. Chemical acid exposure and mechanical damage do not harm the resilient silicate paint surface. Following staining the facade, a silicate paint protective film forms on the surface; this film shields the coating from moisture.

The primary drawbacks of paint are taken into account:

• difficulties when applying to the surface with microcracks;
• insufficient plasticity of the composition;
• have incompatibility with other types of colors, it is undesirable to apply them on already painted surfaces;
• You can not stain metal, stone and ceramics;
• It is not recommended to apply paint inside residential premises – in the kitchen, in the bedrooms.
• In addition to the above minuses, silicate paint is heavily removed from the surfaces, sometimes it has to be removed with a layer of putty.

Specifications

The type of silicatizer used in the composition determines the classification of silicate facade paint. The compounds in Group A have dry pigment. This zinc white typically serves as a silicatizer. Paints with a pigmental pigment are included in Group B. The primary attributes of the paint are:

• In terms of dispersion density, the paint has indicators from 1.30 to 1.70 kg/dm³;
• Covering in Din EN 13300 – grade 2;
• resistance to wet abrasion DIN EN 13300 – class 1 or second (depending on the brand);
• The absorption coefficient of water kg/(m²ch 0.5) is approximately 0.1;
• The degree of re -trotter is approximately equal to 60 microns;
• pH from 8.5 to 11.5;
• Consumption for one layer of 100 – 250 ml/m²;
• temperature when using a composition from +5 to +30 degrees;
• Silicatization time 8 hours.

About 24 hours pass after the first coat of silicate paint dries, and up to 10 hours pass after the second. There is no scent associated with the particular composition.

Main types and manufacturers

There are currently two kinds of LCDs. Based is one of them. There are two varieties of silicate coloring bases:

1. Dispersion-silicate contains up to 10% acrylic. This component acts as a binder. Because of this, the diffusion qualities of the paint are lowered. It is also not necessary to do certain preparation before applying.
2. Silicato-Slyconial allows the surfaces to breathe, thus, air will circulate through the wall. This is due to silicone resin in the paint. This paint is also waterproof and steam, which serves as strong protection against precipitation.

Well-known manufacturers of silicate colors are:

• Baumit Silikat Color Repro Austrian brand, only high cost for the composition and high expense can be attributed to the minuses;
• Pufas Fassaden-Silikat, the German silicate has many pastel shades, as well as inexpensive cost;
• Ceresit CT 54 Polish manufacturer promises increased waterproof, but a large paint consumption belongs to the disadvantages;
• Tikkurila Finngard Silikaat Timalai Finnish coloring composition is resistant to dirt, dust and frost, but the paint consumption is large;
• Caparol Sylitol-Minera production in Germany, the consumption is economical, but you need to apply paint in two layers and the price for it is high.

Surface preparation for staining

It is advised to consider the characteristics of applying the composition on the facades’ surface before applying silicate paint. First, you must look for additional coloring materials on the surface.

There shouldn’t be any evidence of aged plaster on the facade. Silicate paint may exfoliate in the future if you don’t thoroughly inspect the surface.

To ensure there is no excess moisture, the facade is primed before the composition is applied. The surface is also examined for any patches. If the wall has different colors, the paint job will result in a heterogeneous color scheme. Experts recommend painting the facade during inclement weather and avoiding direct sunlight, rain, and snow. The ideal range for work temperature is 0 to +5 degrees.

Silicate paints are a long-lasting and environmentally responsible way to improve your home’s facade. The mineral content of these paints is well known because it forms a chemical bond with the substrate to produce a finish that lasts a long time. Silicate paints, in contrast to conventional paints, ensure superior breathability by penetrating the surface instead of forming a film on top.

The resilience of silicate paints to inclement weather is one of their main advantages. They resist color fading over time due to their high resistance to UV radiation. Because of this feature, they are perfect for areas with strong sunlight, so your facade will continue to look vibrant for many years.

The inherent resistance of silicate paints to mold and algae is another benefit. These paints’ high pH level inhibits organic growth, requiring less maintenance and maintaining the clean, fresh appearance of your facade. This feature is especially helpful in moist or humid environments where algae and mold growth can be recurring problems.

To get the best results when applying silicate paints, there are certain guidelines that must be followed. In order for paint to adhere well, a clean, porous substrate is necessary, so surface preparation is essential. Its longevity is also increased and uniform coverage is ensured by applying the paint in thin, even coats.

In summary, silicate paints provide a long-lasting, visually appealing, and environmentally friendly way to preserve and enhance the exterior of your house. These paints improve curb appeal and offer long-term protection against environmental factors thanks to their mineral-based formulation and superior weather resistance. When renovating your facade, think about using silicate paints to have a colorful, long-lasting exterior that resists mold growth.
