Thermal insulation Corundum - reviews and technical characteristics of thermal insulation paint. Ultra-thin liquid thermal insulation corundum - insulating paint, ceramic thermal insulation, thermal insulation coating and anti-corrosion protection Liquid corundum

Thermal insulation 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 with unique properties compared to .

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

Types of materials CORUND

Thermal insulation products of the KORUND company have several varieties:

CORUND ANTIKOR

A universal material applied directly to rusty surfaces. Before application, you just need to walk over the surface with a regular wire brush to remove the dry layer of rust.

The insulation has an additional anti-corrosion property. Thanks to this, the cost of preparing the surfaces to be treated is significantly reduced.

CORUND CLASSIC

It is an ultra-thin material with good thermophysical properties. During the transportation liquid composition The insulation material is practically not divided into fractions.

CORUND FACADE

This type of material is applied in layers (thickness from 1 mm), so it subsequently looks like. FACADE heat-insulating paint also has only positive reviews from customers. This ultra-thin liquid heat insulator used for concrete surfaces.

FACADE paint also received excellent reviews in combination with ANTIKOR paint.

Operating principle and scope of application of CORUND insulation

The essence thermal insulation materials The liquid-ceramic structure of CORUND lies in the needs of those areas where it is extremely necessary to preserve and conserve heat inside buildings. Thermal insulation paint CORUND (characteristics), the temperature of which implies use on the territory different countries(Russia, Belarus, Ukraine, Kazakhstan, South Korea, in Asia and the European Union), has high elasticity.

CORUND materials are widely used in, interior walls, roofs, concrete floors, window slopes, cold and hot water, steam pipelines, cooling systems.

Liquid thermal insulation CORUND, reviews of which say that it can also be used for insulation of refrigerators, trailers, tanks and other containers.

The temperature range for using materials is from +250 o C to –60 o C.

Specifications and Benefits

In one of the articles we helped you understand. Today we will talk about a composite with high thermal insulation properties, called liquid thermal insulation “Corundum”. Without exaggeration, it is the first domestic product created in our country using national technologies using high-quality imported raw materials. This is the best material in its niche in terms of the ratio of the quality of the result and the cost of the material.

Meet liquid thermal insulation Corundum

The consistency is more like mastic.

The mentioned ultra-thin liquid insulation “Corundum” is made on the basis of:

a binder made on the basis of high quality acrylic with the addition of unique catalysts and various fixatives;
microspheres made of ceramics with ultra-thin walls that contain rarefied air.

In addition to the main composition, the mentioned thermal insulation “Corundum”, reviews of which are extremely positive, includes special additives. They eliminate the occurrence of corrosion on metal surfaces and the appearance of fungus from excess moisture. This combination made it possible to obtain a light and flexible material with the highest adhesion to almost any surface it covers. If you want to understand what liquid insulation Corundum is, reviews on the Internet and the public press will help you with this.

It is a white paint-like suspension that can be easily applied to surfaces of any shape, be it brick, concrete, plastic or metal.

After it has completely dried chemically, a very elastic polymer-based coating is obtained on the treated surface. It has the highest heat insulating properties and allows you to create effective protection against corrosion. Isolation is applied when executing roofing works and arrangement of building foundations, as well as on life support systems. We have already told you. The use of Corundum makes it possible to almost completely eliminate the occurrence of condensation on supply pipelines cold water. The material significantly reduces heat losses heating systems.

Characteristics of the material "Corundum"

Multi-colored dyes can be added to the white composition.

Thermal insulation Corundum, the technical characteristics of which are given below, is in demand at any facility. Before starting work, the specified insulation can, if necessary, be diluted with ordinary water.

The film of this thermal insulation, which is only 1 mm thick, begins to decompose if the temperature exceeds 840 degrees. The process takes place with the release of nitrogen and CO, which allows to slow down the processes of combustion and smoke. The thermal insulation capabilities of ultra-thin liquid insulation exceed the parameters of sheet and roll insulation, the thickness of which can reach 5–7 cm, as well as brickwork, made in one row.

Corundum insulation paint can be applied almost anywhere. The requirements for the surface before applying the material are minimal:

it must first be degreased;
remove dirt;
clean from dust and, to a first approximation, from rust.

Temperature work surface should be between 7-150 degrees Celsius. The temperature range declared by the manufacturer for operation is - 60/+ 260 degrees. Warranty period ≥ 15 years.

Application of liquid insulation Corundum

Apply like paint - acts as a thermal barrier.

Thermal insulation paint Corundum can be applied with a brush, roller, or conventional spray gun. Sprayers allow you to get more high quality application and reduce material consumption. The average thickness of the layer applied at a time is 0.38 mm. After application, a dense film is formed on the surface within 1/3 hour, impermeable to moisture. Complete chemical drying of the applied layer of thermal insulation takes at least 24 hours. Only after this is it allowed to apply a second layer. If you work with a roller, it average consumption equal to 0.5 l/m. sq.

Modifications of "Corundum",

"Classic";
"Anticor";
"Winter";
"Facade".

The first option is the most universal version, which is used for both external (facade, roofing) and interior work(thermal insulation of various pipelines, floors, window slopes). The second material can be applied directly to the corroded surface. Before work, it is enough to remove loose loose rust.

Any modification in which Corundum insulation is offered (reviews from professional builders confirm this) has additional properties that make it possible to ensure reliable protection metal surfaces from corrosion.

The performance characteristics correspond to the basic version of Corundum. Using the material to insulate finished structures and laid pipelines can significantly reduce labor costs. No special preparation of the treated surfaces is required. Saving material and money, without compromising the quality of the work performed, is achieved due to the fact that “Anticor” is applied only as the first layer, and then “Classic” is used.

The “Winter” brand can be applied at outdoor temperatures down to (-10) degrees. This is one of the latest developments from the manufacturer. The composition of the material includes multi-composite acrylic polymers, dispersed, as well as a number of additives.

The “Facade” version was created specifically for concrete surfaces, as well as objects built from slag concrete and foam concrete, which allows us to talk about the material as an ideal option for professional insulation in construction. The optimal values of vapor permeability of this material are comparable to similar values inherent in quality paint for facades. The Corundum material in any of its modifications is today the best choice for providing high-quality thermal insulation at minimal cost.

Not so long ago, the range of building thermal insulation materials was replenished with another new product, which combines best qualities insulation materials of different generations. Thermal insulation Corundum, which is produced by NPO Fullerene and sold practically throughout our country, is one of the popular varieties of this material. Let's look at the properties, features and applications of this thermal insulation.

Liquid insulation: what is it?

It is believed that the basis for the manufacture of this type of material was the development for the space industry. This composition was developed for the external coating of modules and vehicles intended for flights in Earth orbit. We don’t know for sure whether this is true or just another beautiful legend, but the special properties of this material are obvious. What is liquid thermal insulation made of?

The material is based on hermetically sealed ceramic capsules filled with inert gas. Acrylic polymers were used as the connecting suspension. Thus, about 85% of the total mass of the material is ceramic microspheres, and the remaining 15% is the connecting mixture.
Such an unusual composition makes liquid insulation a truly unique material. Suffice it to say that just 1 layer of such insulation will completely replace a 50 mm layer of basalt wool. The liquid insulator has a thermal conductivity coefficient of 0.01 W, which is currently considered the lowest. The material does not absorb moisture at all. After drying, the insulation forms an even, homogeneous layer, insensitive to rain, frost, ultraviolet radiation, high temperatures and mechanical stress. It does not evaporate moisture and does not emit compounds harmful to humans. In addition, it does not need to be covered. finishing, he has high degree aesthetic appeal.
As for application, it does not require any special skills or equipment. It is enough to arm yourself with a brush, spatula or roller. The insulation is diluted with water to the desired consistency and then applied to the surface to be insulated. Number of layers for different walls can vary from 3 to 6. As you can see, in terms of this indicator, this type of insulation has significant advantages.

Basic properties of corundum thermal insulation

Thermal insulation corundum has a microporous structure that reflects about 85% of radiation. A significant reduction in heat loss occurs due to the low thermal conductivity coefficient. What other properties can this insulation boast?

The temperature regime in which thermal insulation retains its effectiveness and properties is from -60 to +250 degrees Celsius.
The manufacturer promises to preserve the properties of the material for 15 years.
For greater safety, the Corundum heat insulator is also available in a frost-resistant modification. Storage of such material is allowed even at temperatures of -30 degrees. True, in such unfavorable conditions thermal insulation can be maintained for no more than 1 month. Allow 5 cycles of freezing the material before using it.

Heat insulator Corundum is available in a whole range of modifications

The material Corundum Classic is a universal heat insulator, which is used for insulation of external and internal surfaces residential, industrial, office buildings and structures, pipeline systems, as well as refrigerators, tanks and other industrial containers. The heat insulator is available in plastic buckets, which can have a volume of 5,10 or 20 liters. Cost - from 300 rubles per liter. When purchasing in bulk, you can get a discount (approximately 10%).
Insulator Corundum Facade is specially designed for thermal insulation of facades made of all kinds of materials. This insulation can be applied directly to outer wall buildings with a layer thickness of 1 mm per application. This modification has increased vapor permeability, which ensures natural ventilation of the building. Thermal insulation Corundum Facade has proven itself in eliminating fungi, mold, freezing of walls or structures. The material is produced in plastic buckets with a capacity of 5, 10 or 20 liters. Price - from 330 rubles per 1 liter, with wholesale purchases you can get an additional 5-15% discount.
Thermal insulation Corund Anticor is unique in that it can be applied to a rusty surface. It is enough to remove the outer layer of rust, which is loose and easy to clean with a wire brush. After this, insulation can be applied. Corundum Anticor not only preserves the surface and has anti-corrosion resistance, it effectively prevents the spread of oxidation deeper and wider than the surface. This type of material is successfully used for insulating pipelines and metal structures, and also as a base layer for the subsequent application of other products of the manufacturer, for example, Corundum Classic. The insulator is available in plastic buckets with a volume of 10 or 20 liters. The cost of 1 liter of Antikor is from 410 rubles. When purchasing in bulk, you can count on a discount of about 10%.
Thermal insulation Corundum Winter is perfect for those cases when the work on thermal insulation of the facade falls on winter time of the year. The coating is intended for objects requiring high-quality thermal insulation, including those susceptible to corrosion and prone to condensation. We remind you that most known thermal insulation materials can be worked at temperatures not lower than +5 degrees. Corundum Winter can even be stored at low temperatures(up to + 30). The insulation is supplied in a plastic bucket with a volume of 20 liters. 1 liter of liquid winter modification insulator costs from 420 rubles.
A material under the working title Corundum Fire Protection is under development. It is intended to increase the fire resistance limit of residential and industrial buildings and structures. Under influence high temperatures the coating provides fire resistance of 1 hour with a dry layer thickness of 1.5 mm. The coating system consists of a primer, a fire retardant material and a finish coating with fire resistant properties.
Thermal insulation Corundum can be used comprehensively, in a combination of several materials. For example, to insulate a metal surface, a layer 2.5 mm thick is required. In order to achieve this indicator as efficiently as possible, you can use the Corund Anticor modification for the primer, and then apply two layers of Corundum Facade. Thus it will turn out required thickness insulation of 2.5 mm, which will provide an anti-corrosion, moisture-resistant and heat-insulating surface coating.

Areas of application

What can Corundum thermal insulation be used for?

For insulating walls, both inside and outside the building
For insulation of facades
For insulation of floors, including attics and roofing structures
For thermal insulation of pipelines, both indoors and those running through open areas.
For insulating industrial non-insulated tanks, including tanks and refrigerators.
Thermal insulation Corundum is used where it is not possible to use other types of insulation due to difficulty of access or operational features of the structure.

In conclusion, let us turn to the dry language of numbers, which will confirm the properties of liquid thermal insulation.

So, the thermal conductivity coefficient of Corundum thermal insulation is from 0.01 to 0.02 W. Material consumption is 1 liter per 1 square meter area, the water absorption coefficient is 0.04 grams per 1 cubic centimeter of area (the indicator is calculated for material completely immersed in water for 24 hours).

Density in liquid form is from 450 to 550 kilograms per cubic meter. The material can withstand shock loads of 50 kg per square centimeter. The vapor permeability coefficient is low, it ranges from 0.02 mg/m h Pa. But the material does not allow water vapor to pass through and prevents increased humidity in the room.

So the use of Corundum thermal insulation is not only the use of the latest insulation technologies with maximum efficiency and ease of application. It also provides protection from moisture, rust, and other adverse and aggressive influences for a period of 15 to 20 years.

INSTRUCTIONS for applying ultra-thin thermal insulation CORUND

CORUNDUM- a film-forming coating intended for thermal insulation of metal, plastic and other surfaces with operating temperatures from -60 °C to +200 °C (in peak short-term mode up to +260 °C). CORUNDUM fits well on all types of surfaces. Insulation work can be carried out on surfaces with temperatures from +7 ºС to +150 ºС.
When working with liquid thermal insulation coating CORUNDUM should Special attention Please note: Corundum should not be frozen. Before opening the container, you must ensure that the seals are intact. When preparing the material, do not overmix (see paragraph 2 of these instructions). When preparing the material, you must not dilute it excessively with water (see paragraph 2 of these instructions)

1. Surface preparation

The insulated surface must be cleaned of dirt, rust, dust, old paint, remove crumbling elements, etc. Pay special attention to ensure that there is no “loose” rust in the form of “fungus” on the metal, which after application CORUNDUM will peel off from the metal along with the coating. Clean metal surfaces from rust using metal brushes or abrasive wheels removing the loose layer of rust until a metallic sheen appears.
The rust-free surface is treated with a rust converter and, if necessary, kept for 2 hours. New metal surfaces may require preservatives to be removed. The finished surface should not contain crumbling elements, should be dry (including not condensing), should not contain oily or greasy elements, and should not be overly plastic. If CORUNDUM is intended to be used on ferrous metal surfaces, with operating temperatures up to +150 °C, then the surface must first be dedusted and degreased, coated or modified CORUND ANTIKOR (preferred), or treat with primer VL-02 or VL-023 (in 1-2 layers in accordance with the instructions for the primer).
If the coating is supposed to be applied to the surface of non-ferrous metal, then it is necessary to treat the surface mechanically to remove the gloss, remove dust, degrease, and treat it with adhesive primer VL-02 or VL-023 (1-2 layers).
If CORUNDUM intended to be applied to concrete, brick and similar surfaces, it is necessary to: remove loose areas, expand cracks, remove oily inclusions, clean concrete from cement laitance, repair the surface, including inter-brick joints to reduce material consumption and excavations deeper than 5-7 mm, cement-plaster compositions. Clean the surface using a sandblaster, metal brush or abrasive wheels to remove gloss on the surface and remove falling off and crumbling structural elements.
After machining The surface should be thoroughly dusted using brushes or blowers. Afterwards, it is necessary to rinse with water to remove dirt, remaining dust, etc. After complete drying, it is necessary to prime acrylic primer deep penetration.
To apply to the façade of enclosing structures of buildings and structures made of vapor-permeable materials (concrete, brick, etc.), it is necessary to use a modification CORUND FACADE.

2. Preparation of CORUND insulating coating

CORUNDUM ready for use, it must be mixed, if necessary, adding a little distilled water, immediately before application to a previously prepared surface. The amount of water depends on the temperature of the application base, the temperature and humidity of the surrounding air, subsequent use and other factors. When applied to a surface with a temperature from +7 °C to +80 °C, the amount of water added to the material can be no more than 5% when applied with a brush and no more than 3% when applied with equipment (airless spraying apparatus). When applied to surfaces with temperatures above +80 °C, it is necessary to first lower the temperature by applying several primer layers of Corundum material diluted with 40-50% distilled water according to the scheme specified in paragraph 3 “Coating Application”. For detailed recommendations, contact your nearest representative or manufacturer. At long term When stored inside the container, separation into fractions is allowed.
When using a drill with a paddle attachment or a mixer (for recommendations on choosing equipment, check with your Korund representative in your region) - the maximum permissible mixing speed is - 150-200 rpm. Exceeding the rotation speed will lead to the destruction of the microsphere and a radical decrease (or cancellation) of the thermal insulation efficiency th covering.
Using vertical movements of the blade to immerse the thickened part in the liquid, turn on the drill and slowly begin to rotate the blade, mixing the curds with the liquid. Stir until the product resembles cream. Approximate mixing time - with a mixer 3-8 minutes, manual mixing 7-10 minutes.
If the task is to eliminate condensation, a “coat” of frost, the material is applied with a minimum addition of water, with a maximum interlayer gap.

3. Coating

It is recommended to use a soft brush with long natural bristles or an airless sprayer (check with your local representative for recommended brands and models of airless sprayers, as well as recommendations for setting them up).
You can apply the coating to small surfaces or areas with complex configurations using a soft brush. Surfaces over 100 m2 can be treated using an airless sprayer with a working pressure of no more than 60-80 bar ( IMPORTANT!!! Not all airless sprayers are suitable for working with Corundum coating!!! For recommendations on selecting, setting up and working with airless sprayers, check with the manufacturer or your nearest Korund representative. Also see additional data sheet for airless sprayers.)
The insulating coating can be applied to surfaces with temperatures ranging from +7ºС to +150ºС. You cannot work in humid weather, because The material is liquefied by water and will not dry out.
For better adhesion of the material to the surface being treated, it is recommended to apply a primer layer to the prepared surface using a liquid (like milk) composition of the material, diluted with 40-50% distilled water.
The time for complete drying of one layer of coating with a thickness of 0.4-0.5 mm is at least 24 hours at an ambient temperature above +7 ° C and humidity not higher than 80% throughout the entire drying time, i.e. 24 hours. The next layer can be applied only after the previous layer has completely dried - after 24 hours at room temperature. A layer of about 0.4-0.5 mm (optical density thickness) is obtained with three “passes” of the sprayer or brush. Applying the material in a thicker layer is unacceptable, as this leads to the formation of a moisture-proof film on its surface, which in turn prevents the complete evaporation of the moisture contained in it, which will lead to the cancellation of the thermophysical properties and deformation of the coating.
When applying the material to a surface with a temperature from +80 ºС to +150 ºС, the material boils and “sets” very quickly, so the material must be diluted with water. It is recommended to prime the surface with a 40-50% aqueous solution of the material. IMPORTANT! When applied CORUNDUM on surfaces with temperatures above +80 °C, the thickness of the maximum layer in 24 hours should not exceed 0.5 mm. The hotter the application surface, the more the material is diluted. The diluted material is applied with quick short movements; with this application the layer will be very thin. The drying time for each layer is at least 1 hour. Such layers are applied until the applied material stops boiling on the surface. After this, allow to dry for 24 hours. Then the material is applied according to the usual scheme - with the addition of 3% to 5% distilled water in layers up to 0.5 mm with interlayer drying for 24 hours.
The thickness of a layer of 0.5 mm can be determined with a thickness gauge of the “painting comb” type, with a material consumption of 0.55 liters per 1 m2 (approximate consumption when applying the coating with a brush to flat surface) or the thickness of the “optical density” of the material (so that the underlying material does not show through). The material consumption is affected by the type of surface and method of application.
The total thickness of the coating and the number of layers is determined thermotechnical calculation or recommendations from certified regional production representative offices.

The number of layers and the final thickness of the heat-insulating layer is determined by thermal engineering calculation (if it is applied to an inter-apartment ceiling, the total thickness of the layer should be about 1 mm), while the thickness of the applied layers should not be more than 0.5 mm (!).
8. Next stage: installation of a heat source for the “Warm Floor” system.
9. The last stage: the finishing coating, which can serve as a floor covering ceramic tile and other floor coverings.

The manufacturer is responsible for compliance of the coating with the declared characteristics only if the storage and operating conditions are fully observed.

Ultra-thin thermal insulation Corundum is a paint composition used to reduce heat loss from buildings, pipes, tanks and other objects. I will briefly describe the principle of operation of the paint, talk about its varieties and give tips on how to use it yourself.

What you need to know about thermal insulation paint

How does liquid insulation work?

Liquid ceramic thermal insulation, which includes Corundum insulation, has a complex structure. Usually, the paint consists of four components:

The basis- acrylic or latex dispersion with water as a solvent. Connects all components into a single complex, is responsible for securing the insulation to the object and for the formation of a continuous film.

Granules- carriers of basic thermal insulation properties. These are perfectly round spheres made of ceramics or foam glass. Inside the granules there is either a vacuum or very rarefied air, which ensures a decrease in thermal conductivity.
Pigment. Liquid insulation still belongs to the category of paints, which is why colored components are added to it. Usually the compositions are made white, but sometimes they are also tinted - products for ordinary acrylic are suitable.

Modifiers. Various additives that improve the functional characteristics of paint. This may include silicone, which prevents cracking of the material, anti-corrosion components, additives that increase cold resistance, etc.

When applying paint to the surface, the granules are distributed in the base and cover the object to be insulated. The cavities inside the granules act as an insulator, and the thermal conductivity of the coating is significantly reduced. This is facilitated not only by the large number of hollow inclusions, but also by their tightness.

Pros and cons

Corundum insulation (along with similar compounds) is rapidly gaining popularity today. This is facilitated by a number of quite objective advantages of this paint.

On the other hand, Corundum also has disadvantages, and for the sake of objectivity in the table I will present the main pros and cons:

pros	Minuses
Little labor intensity. The composition is applied to a surface of any shape no more difficult than regular paint. In this case, there is no need for either the construction of a frame or subsequent cladding. The possibility of mechanical application further reduces the labor intensity of the work.	Moderate thermal insulation. When treated with Corundum, the reduction in thermal conductivity will not be bad - but by no means outstanding. If we take into account that the material is extremely rarely applied in a layer of more than 2 mm, then the heat loss will still be noticeable.
Small increase in size. The paint demonstrates sufficient efficiency even with a layer thickness of 1 mm. Thanks to this it is possible to provide high-quality insulation even nearby objects.	Efficiency at different temperatures. The higher this indicator, the better the paint works. That is why such products are used mainly for hot pipelines and tanks. On cold water pipes, facades and other structures, I would rather consider such material as additional insulation.
Durability of the coating. The material adheres well to most surfaces (concrete, brick, metal). At the same time, correctly applied paint does not deform or crack when the substrate temperature changes.	High price. The situation is further aggravated by the fact that Corundum needs to be applied in several layers, so the material consumption will be considerable.

Varieties of Corundum

The range of heat-insulating paint compositions is quite extensive. That is why the choice of Corundum material should be made only after studying the entire available line.

The most popular varieties:

Corundum Classic. Basic option liquid insulation, which is used for finishing almost any surface - from facades to cold water pipes. Optimal thickness application - up to 0.5 mm.
Corundum Anticorrosive. It can be applied to the surface without anti-corrosion treatment - it is enough to perform initial cleaning of loose rust flakes. Combines the functions of a heat insulator and a corrosion inhibitor.

The price of the material is higher than that of standard insulating paint. In order to save money, the first layer can be done using “Anticor”, and then use the more affordable “Classic”.

Corundum Facade. Focused primarily on painting concrete surfaces. The material can be applied in a layer 1 mm thick, and after drying it retains high vapor permeability. Also, dried paint is suitable for finishing with facade compositions (paint, decorative plaster).

Corundum Winter. One of the few thermal insulation materials suitable for use in winter period. Work can be performed at temperatures down to -10 °C, without affecting the adhesion and strength of the applied material.

Application technology

Method 1. Mechanized processing of facades

Thermal insulation Corundum can be used for finishing walls made of a wide variety of materials. It is convenient to use sprayers for this - and brief instructions will help you choose optimal sequence actions:

Illustration	Work stage
	Mixing the composition. After opening the container, mix the paint to distribute the granules in the binder. To avoid destruction of ceramic inclusions, mix either manually or with a mixer at low speed.
	Preparing the spray gun. Before starting work, remove all filters (usually in the receiver and gun handle) - they will trap granules and quickly become clogged. After this, fill the reservoir with mixed paint.
	Surface preparation. We clean and remove dust from the façade, removing loose fragments. When applied to metal surface Anticorrosive paints remove rust flakes: brushing or complete cleaning sandblaster not required.
	Coloring. Spray the composition over the surface in a layer of no more than 0.3–0.5 mm. The next layer can be applied only after the previous one has dried.

Method 2. Painting thermal insulation of pipes

Corundum paint can also be applied with your own hands using a roller or brush. I will tell you about this processing method using the example of thermal insulation of pipes:

Illustration	Work stage
	Mixing paint. As in the previous case, thoroughly mix the composition immediately before application.
	Pipe preparation. Using a metal mesh, brush or emery, we clean the pipe from rust.
	First coat of paint. Apply Corundum thermal insulation with a brush or roller. Thoroughly rub the paint to form a layer no thicker than 0.5 mm.
	Repainting. We wait for the composition to dry and repeat the operations until the designed thickness of the thermal insulation layer is reached.
