Liquid thermal insulation: reviews and recommendations

Thermal insulating liquid material produced by KORUND, based on its physical properties and consistency, is very similar to ordinary white paint that is used to paint standard surfaces. Thermal insulation CORUND has only positive reviews. All this is due to the fact that the material consists of a high-quality acrylic binder component, ultra-thin ceramic microspheres with a composition of rarefied air and a specially developed composition of fixatives and catalysts.

In the production of such materials, special additives are also used that completely eliminate the occurrence of corrosion and fungal accumulations in conditions of high humidity. Thanks to this composition, liquid thermal insulation CORUND (read reviews on our website) is flexible, soft, light and stretchable.

After application, the insulation forms an elastic polymer sheathing that has unique properties compared to traditional heat insulators.

The new generation material has already proven its reliability as a temperature preservation component. In addition, CORUND thermal insulation has technical characteristics favorable for combating corrosion and the appearance of condensation on cold surfaces.

Features of liquid thermal insulation

Initially, the composition was developed for the space industry, but later builders became interested in it.

This new material differs from conventional insulation in the method of application. It is distributed over the surface using a brush, spray or roller. Liquid thermal insulation, reviews of which are contained in the article, should be a layer approximately 1 mm thick.

After application, the composition polymerizes and forms a film with energy-saving characteristics.

Positive properties of Alfatek thermal insulation

Thermal insulation materials from this manufacturer have the same positive properties as all liquid insulation materials, namely:

Low material consumption and low dead weight, which avoids increasing the load on structural elements;
A high level of adhesion to the base material and increased elasticity parameters ensure a minimum service life of 10 years;
The material does not lose its physical properties over a wide range of temperatures: from −50 to + 250 °C;
The characteristics of the material make it easy to “repair” damaged areas - they can simply be painted over with a new layer of heat insulation;
When organizing a new thermal insulation system, Alfatek insulation will not require dismantling;
The liquid aggregate state of the insulation allows you to effectively treat problem areas such as small crevices, cracks and voids.
This product can be used for external and internal thermal insulation work;
The special physical properties of the material allow it to be used as a paint for pipelines, significantly reducing heat loss in communication systems;
Alfatek materials are chemically inert and also protect structures from the development of fungus and mold.

The features of Alfatek liquid thermal insulation are especially useful in the following types of insulation work:

Buildings and production facilities that place increased demands on the quality of insulation;
Objects subject to condensation and, as a consequence, the development of corrosion;
Objects that cannot be insulated using traditional methods;
Objects primarily made of metal.

However, Alfatek products can also be successfully used for traditional thermal insulation work in residential premises.

Well-known manufacturers of liquid thermal insulation and reviews of their products

Today in stores you can find thermal insulation compounds of different brands. The most famous of them: “Corundum”, “Magnitherm”, “Astratek”, “Bronya” and “Akterm”.

All these compositions differ in manufacturer and area of application. Liquid thermal insulation, reviews of specific brands of which will be presented below, can be used for building facades, roofing materials or pipes. The convenience of its use also lies in the fact that it can easily be used to cover small parts of devices, handles and valves on equipment.

Types of paint Corundum

Ultra-thin thermal insulation Corundum comes in several types. These modifications differ from each other in properties and some features:

Corundum Classic. This substance is highly effective and is excellent if you need to insulate walls inside and outside, facades, roofs, concrete screeds, pipes (both warm and cold), window slopes, etc. Corundum Classic is also suitable if you need to properly process existing air conditioning systems and steam lines. In addition, Corundum Classic prevents condensation from forming on the surface, and such a layer reduces heat loss.
Anticorrosive This insulation is unique due to the fact that when applied to metal surfaces it prevents corrosion. The uniqueness of this product also lies in the fact that it can be applied to an already rusty layer. It only needs to be removed by rubbing thoroughly. This substance prevents further corrosion processes. In addition, the material also has good thermal insulation properties.
Corundum Winter. It is allowed to work with such a product in slight frost, that is, even if the air temperature is minus 10°C. It will not freeze or undergo polymerization due to low temperatures. For conventional ceramic-type heat insulators, the maximum temperature is only +5°C. Corundum Winter contains acrylic-type polymers and foam glass microgranules that are dispersed in them. Thermal paint Corundum additionally includes pigments, rheological components, inhibitors and a fire retardant, which is important to consider when choosing.
Corundum Facade. This is another paint modification. It was developed specifically to be applied to concrete surfaces. The use of such material is associated with heat-reflecting properties. It is necessary to apply paint in a large layer to speed up the process. In addition, this product is resistant to environmental factors and has good vapor permeability. Excellent for facades and as a decorative layer.

Liquid thermal insulation “Corundum”: reviews and application features

Such thermal insulation is in demand among buyers, this is explained by its ease of use. To apply the material you do not have to buy additional devices. A roller, brush or spray will be enough.

The process of distributing material over the surface requires extreme care from the performer. It is better to form the required heat-protective layer 1 mm thick in 2-3 approaches. Each stage is carried out approximately 24 hours apart.

The service life of the coating depends on the accuracy of following all instructions. This indicator is also influenced by the condition of the surface on which the composition is applied. For example, liquid insulation “Corundum Anticor” should be distributed only over metal that is well cleaned of rust. This can be done with a special brush.

Liquid thermal insulation “Corundum”, reviews of which are almost always positive, is produced with a special composition for application in the cold season. It is worth considering that there should be no ice or snow on the working surface at this time.

According to reviews from owners of private houses, Corundum perfectly protects basement pipes. If applied correctly and the technology is followed, even after several years no defects are observed on the treated metal.

The high speed and ease of application of the Corundum composition gives it an advantage over similar rolled materials. This also reduces the labor intensity of the work.

It is important to purchase products only from authorized dealers, since only the original composition has all the listed properties.

Specifications and Benefits

Since CORUND thermal insulation (you can read reviews on our website) can completely merge with the surface and fill almost all micropores, the concentration of the material in the polymerized state is 80%.

The main technical indicators of heat-insulating paint (reviews) are as follows:

does not collapse under the influence of ultraviolet radiation;
the application method is similar to paint;
has a thermal barrier effect;
does not allow moisture to pass through and is not exposed to saline aqueous solutions;
protects the surface from moisture, temperature differences and precipitation;
does not support combustion (at a temperature of 800°C the material undergoes decomposition with the release of nitrogen and carbon oxides, at a temperature of 260°C the material simply begins to char);
CORUND thermal insulation also exhibits technical characteristics in terms of environmental friendliness of the product (does not contain harmful organic compounds);
1 mm of thermal insulation layer is comparable to 50 mm of rolled insulation.

The main advantage of heat-insulating paint CORUND: characteristics, heating temperature.

You can work with liquid heat-insulating paint without additional ventilation. Compared to other thermal insulation materials (rough and hard), liquid paints are applied much faster and easier.

In addition, a thin liquid layer of insulation is much lighter in weight than, for example, a thick-walled material.

Liquid thermal insulation "Magniterm": reviews and characteristics

There are several types of Magniterm composition on the market. Liquid thermal insulation, reviews of which will be below, is produced for building facades, balconies, floors and basements.

Magniterm Nord deserves detailed consideration. This composition can be used from - 30 to + 80°C. The resins that make up the heat insulator create a thin layer on the surface that allows steam particles to pass through. Moisture does not pass through Magniterm Nord.

Before applying thermal insulation, you need to carefully prepare the surface, that is, clean it of loose areas, oil stains and metal chips. It is advisable to cover everything with a layer of acrylic primer for concrete.

It is worth keeping in mind that before use it is necessary to dilute Magniterm. Liquid thermal insulation, reviews of which are not always positive precisely because this stage of work was carried out incorrectly, is diluted only with high-quality non-toxic liquids. Otherwise, the smell may cause intoxication among residents.

Application of insulation

Having studied the description of the paintable compositions, you can already roughly imagine where they will work most effectively. Corundum insulation is used in somewhat non-standard conditions - where other materials do not give the desired result:

Insulation of heating, water supply, air conditioning and industrial transport systems.

Branched pipes, adapters, tie-ins and fittings - all this also requires the use of insulation. Liquid ceramics creates a continuous, tear-free layer on any complex surfaces. It is much easier to paint pipes than to try to squeeze and secure rolls of glass wool into a confined space, risking leaving “cold bridges”.

Tanks containing flammable or unstable media.

Ultra-thin liquid thermal and waterproofing Corundum not only maintains the temperature inside the containers, but also reflects external IR radiation, protecting the contents from dangerous heating. By the way, the same effect made it possible to find another application for it - painting metal roofs, which on a sunny day heat up to +70..+90 °C.

Steel pipes.

Absolute vapor and water resistance, as well as the thermal insulation properties of ceramic paint prevent not only steel elements from getting wet, but also the appearance of condensation on their surface. We mentioned this at the beginning of our review. Thus, Corundum plays the role of an anti-corrosion coating, ensuring a long service life of metal structures, as well as reducing the costs of their maintenance and repair.

Thermal insulation of external and internal walls of buildings.

For example, protection of loggias and balconies from freezing is carried out from the inside. But mineral wool and polystyrene “steal” a few centimeters on each side of the room. The use of Corundum compounds allows you to achieve the desired effect by simply painting the walls with insulation and thereby preserving the usable area. In addition, liquid ceramics, according to reviews from residents of panel houses, helps to cope with fungus that constantly appears on the damp surface of concrete. And on the facades it serves as a separator of different temperature environments and a reflector of sunlight in summer.

Customer reviews about liquid thermal insulation "Astratek"

Liquid thermal insulation "Astratek", reviews of which will be presented below, is intended for thermal insulation of facades, concrete floors, gas pipelines, sewerage, roofing and metal structures. Work with it can be carried out in a wide temperature range from - 60 to + 250°C.

This is a fairly new material, so buyers do not yet have reliable information about its environmental safety. Manufacturers claim that Astratek does not harm human health. Some buyers doubt this.

Liquid thermal insulation “Astratek”, reviews of which speak of the ease of its application, provides 100% adhesion to the material. After distribution over the surface, it does not weigh down the structure, especially for metal elements.

"Astratek" is a liquid ceramic thermal insulation. Reviews about it left by customers contain information that the liquid also protects against corrosion, condensation and mold.

For information

Liquid thermal insulation Corundum is a mixture based on an acrylic binder and ceramic microspheres, which have thin walls and contain rarefied air inside. Acrylic binders are created using substances from the group of catalysts and fixatives.

Microspheres have sizes up to 0.5 mm. In addition, it contains various additives, so if Corundum is chosen, the facade will be processed very efficiently, since such additives enhance certain qualities of the product. The composition is completely balanced, so the material is elastic, light and stretchable. In addition, the Corundum coating has good adhesion.

The consistency of the substance resembles simple paint. This is a whitish suspension. The material not only has thermal insulation properties, but is also able to protect metal parts from corrosion.

In addition, Corundum is a thermal insulation that has many other advantages:

Keeps warm well. It has been established that 1 mm of such paint is comparable in its ability to conserve heat with 5 cm of roll-type insulation (for example, mineral wool). The reviews are very good.
It is easy to apply the substance to surfaces. The paint must be applied using conventional tools. You can use a spray gun, roller, or brush. The product does not emit harmful compounds, so respiratory protection is not required.
If Corundum is chosen, the facade will be protected from various damages due to the influence of aggressive environmental factors. For example, metal will not rust. Wood does not dry out or rot. The brick, concrete layer and plaster do not crumble and cracks do not appear on them.
If Corundum is applied, the facade will not be destroyed due to the influence of rodents, insects, bacteria and other pests. The surface does not rot. Mold does not form either.
The insulating layer is lightweight. If Corundum is chosen, the facade will not have additional load, as if other insulation materials were used, for which it is necessary to install additional special retaining structures. Due to the light weight of the layer, Corundum can be applied even to fragile surfaces.
There are no seams. Thanks to this, there will be no cold spots. The thermal insulation layer will be seamless, so the cold will definitely not be able to penetrate into the room.
Durability. It is enough to apply the product only once, and you will not need to replace such a layer for a long time.
The use of the material is also associated with its environmental friendliness. Over a long period of operation, such a layer does not emit harmful components. The product can even be used in homes where people who are prone to allergies live.
Neither the area of the room nor its geometry is affected, which is taken into account when using bulky structures. Corundum will not affect the dimensions and shape of the building.
Can be used as a finishing material. Special components from the group of pigments are added to this paint, so it is also used as a decorative coating.

Liquid thermal insulation “Armor”: reviews and recommendations for use

Among all brands of liquid thermal insulation, Bronya is the most popular. This is due to the availability of the material at cost and a wide range of products. At official dealers you can find varieties for processing facades, metal structures and other types of surfaces. Every buyer will find a suitable option.

Reviews from home owners about this type of thermal insulation are most often positive. Negative opinions about the coating usually arise because it was applied incorrectly by the builders.

Manufacturers recommend applying ultra-thin insulation with a soft natural bristle brush or airless sprayer. You should definitely check with the company’s regional representative about the preferred brand of the latter.

Recommendations for use and customer reviews of Akterm liquid thermal insulation

The scope of application of Akterm liquid thermal insulation is quite wide. It can be used for thermal protection of roofs, ceilings, floors, walls, foundations, pipelines, water storage tanks and many other needs. A separate type of material has been developed for each type of surface.

Akterm liquid thermal insulation, reviews of which can be found on many websites and forums, is easy to apply. Buyers say the coating works best when applied in several thin layers. Those who like to do their own repairs also note the almost complete absence of odor from the composition, which makes it easier to carry out work indoors.

Thus, liquid thermal insulation, reviews of different brands of which were presented in the article, can be used for various surfaces. When choosing it, you need to pay attention to the markings. Compositions for facade work are prohibited from being used indoors. For places with high humidity, you can choose specialized liquids.

Application instructions

Before you start applying Corundum paint, you need to choose the right material. You should not buy products from unverified sellers. The manufacturer is the Russian company Fullerene. In addition, there is a network of distributors. Be sure to pay attention to the condition of the paint. It should take the form of a suspension of paste-like consistency with a whitish tint. Traditional packaging is a plastic bucket. It can be of different volumes. The label must contain information about the manufacturer.

As for the cost of Corund paint, it differs depending on the type of material and the place where sales are made. For example, in Russia the cost of the Classic modification for 100 ml is approximately 34 rubles. Anticor coating can be purchased for 450 rubles per 1 liter. Corundum costs from 400 rubles per 1 liter, and Corundum Winter – from 550 rubles.

To apply thermal paint, you need to stock up on the appropriate painting tools. This can be a spray gun, roller or brush. It is best to apply paint using the first option, since it not only reduces the consumption of the substance, but also makes the coating better.

The thickness of one layer of paint should be approximately 0.4 mm. The next layers should be applied only after the previous layer has dried. If you use a brush or roller, the average product consumption is approximately 500 ml per 1 m².

Here is the algorithm of actions:

Pour the liquid into a large container and stir well until it has a uniform consistency. To do this, you can use a special drill with a suitable tip. Experts advise setting the machine to medium speed so that the structure of the ceramic microspheres does not deteriorate during mixing.
Clean the surface to which paint will then be applied. Pre-treat with degreasing compounds. To do this, you can use a special solvent. If the surface is metal, then the rust should be removed.
Allow the surface to dry completely before applying paint. The first layer should be minimal in thickness, since it is a primer.
When using a roller or spray gun, you need to carefully handle joints and other places where there is no access. You'll have to use a brush.
It is recommended to do no more than 3 layers of paint for optimal results.
It will take about a day to dry completely. If you paint warm pipes, the paint will dry even faster.

Thermal paint Corundum will look beautiful, so it can be used not only as thermal insulation, but also as a finishing coating.
