Pink putty. The choice of finishing putty. Types of putties according to the binder component

A well-known material for leveling walls, eliminating gaps or filling joints is putty. It is a mixture that is applied before painting, wallpapering and other construction and repair work.

Blue putty in the decoration of the living room

Nowadays, putty is produced in the form of dry and ready-made mixtures.

Dry mixes contain astringents, which must be diluted with water in the indicated proportions before use. They can be used on all types of surfaces, apply layers of any thickness, but the period of use of dry mixes is limited. Therefore, when preparing putty, this factor must be taken into account.

Unusual wall putty

Various latexes or dispersions are taken as the basis for ready-made mixtures. These mixtures are convenient in that they do not need to be diluted and the shelf life is unlimited. However, they can only be applied with a layer thickness of up to 5 mm.

Putty is also divided into types according to various criteria.

Types of putties for interior work

They are classified according to several criteria:

by composition;
by particle size;
by appointment.

Depending on the composition of the putty, they are divided into: gypsum, cement and polymer.

Gypsum putty is the most common, easy to apply and sand. Its main property is whiteness and plasticity. Gypsum absorbs and releases moisture from the air, so putty from this material is suitable for any room.

Cement putty is mainly used in the repair of rooms with high humidity.

Polymer putty is used for finishing work in rooms that are about to be completed; it is also convenient to use for filling seams and joints.

Beautiful wall finish with putty

Depending on the particle size, putties are coarsely dispersed (particle size - 200 microns or more), medium-dispersed (particles smaller than 80 microns) and finely dispersed (particle size is 20 microns or less).

The purpose of the putty may be different depending on the work performed. Therefore, putties are divided into starting, finishing, universal and specialized.

Starting putty is applied before starting work in order to correct rough surface irregularities. It is selected depending on the material on which it will be applied.

Finishing putty is designed to eliminate minor defects or scratches. As a rule, it is applied in a very thin layer and is not subject to grinding.

Universal putty is suitable for almost all types of surfaces. It can be a replacement for finishing and starting putty, combining their functions. But this putty is expensive.

The purpose of a specialized putty depends on what additives it has. It is used to solve certain problems.

Putties for drywall

Drywall is a very convenient and practical building material. It is used for ceilings, walls, frames, partitions when repairing an apartment. After sheathing walls or ceilings with drywall, it is necessary to putty all the irregularities that are visible on the sheets of drywall.

When leveling drywall, various types of putties are used. First of all, you need to evaluate the sheets. If the sheet of drywall is even, then it will be enough to cover up the places where the screws are screwed in and the places where the sheets are joined.

Cream putty in wall decoration

It is also important to evaluate whether wallpaper will be glued or whether walls or ceilings will be painted, because it will also be necessary to choose a specific putty.

Gypsum putty is more often chosen for puttying drywall. Since it has the property of plasticity, it is convenient to use. But, if the room in which the walls or ceiling are being finished has high humidity, it is better to use cement putty.

Brown putty on the wall

Before painting or gluing wallpaper on drywall, various polymer putties are often applied. The most popular is acrylic putty. It can be used in various rooms, but its cost is high.

Also, when choosing a putty for drywall, it is necessary to take into account its purpose. When leveling gross defects, choose starting putties, for sealing small cracks and scratches - finishing.

Putty for painting and wallpapering

Before painting the walls and ceiling or gluing them with wallpaper, as mentioned earlier, it is necessary to putty all the irregularities. Sometimes they also putty so that the paint or wallpaper fits well.

Peach putty in the kitchen

In such cases, polymer putty is best suited. It is of the following types:

Adhesive putty, which contains glue, drying oil and chalk. Most often it is used before wallpapering the walls.
Oil-adhesive putty consists of components such as water, drying oil, plasticizers. Suitable for both painting the ceiling and wallpapering the wall.
Latex putty, which is very similar in composition to oil-adhesive plaster. Only its composition is supplemented with calcite filler.
Acrylic putty is prepared from chemical raw materials. It can be said to be universal, because it combines all the properties of other leveling mixtures.
Oil putty consists of desiccant, chalk and drying oil. It is convenient to use before painting the ceiling or walls in rooms with high humidity.

As you can see, in the modern world there is a variety of putties for painting and wallpapering. By choosing the right putty, you can get smooth and beautiful ceilings and walls.

Wood putty

In a separate group, you can put putties on wood. They contain synthetic resins and pigments. Pigments allow you to get different shades of wood.

To date, there are only two types of putties on wood: solvent-based and water-based. These types are divided into the following types:

Solvent-based putties are used only in production. They are toxic and unsafe for humans. But the advantages include: a variety of shades of wood, resistance to various temperature conditions and quick drying.
Acrylic putties are mainly used for decorative flooring made of wood. The advantages of this putty are that it is moisture resistant and fire resistant, but large defects cannot be corrected with it.
Epoxy putty is practical. It is odorless and does not settle when dry. When puttying a wooden floor, it is better not to use it.
Latex putties are versatile and ideal for working with wood surfaces. They are considered environmentally friendly, odorless and dry very quickly.
Oil putties on wood are considered strong and durable, but they dry for a long time.
Gypsum wood putties are the cheapest and level any wooden surface.

These are all types of wood putties that currently exist.

Decorative putty

Increasingly, putty began to be used to decorate the walls and ceilings of apartments. The stores offer a wide selection of decorative putties. Consider the main types of decorative putties in terms of composition and texture.

The composition distinguishes the following decorative putties:

mineral putties, consisting of sand, gypsum and limestone. They are not expensive. But after applying this decorative putty, it is also necessary to apply a protective layer so that nothing falls off.
polymer putties have high plasticity and resistance. They include acrylic, epoxy.
silicone putties are considered the most expensive, but do not collapse and are durable.

Sand-colored putty on the walls

By texture, decorative putties are divided into:

Structural, based on latex or silicates. The particles of this decorative putty are of different sizes.
Textured, which create a semblance of fabric, stone and wood. The cost is quite expensive.
Flock, which include cellulose, silk fibers, etc. They are the most expensive of all decorative putties. But they can create an imitation of different types of fabric.

In the modern world, putty is not only a material that levels various surfaces, but also decorates the walls and ceilings of a house.

Putty for leveling and creating a smooth surface of walls before decorative finishing, types of material, composition of mixtures and their properties.

The content of the article:

Wall putty is a building material designed to level the wall surface and finish it before final finishing, such as wallpapering or painting. The processing of the base with putty is an integral part of the technological process for the repair of premises. The final result largely depends on its qualitative characteristics.

Varieties of putty for walls by grain size

Putty is divided into two types, taking into account the grain size, which determines the purpose and sequence of applying the solution. So, putty can be starting, finishing, universal. The names speak for themselves, however, what are the main differences between these species. Let us describe their characteristics in more detail.

Starting wall putty

The starting putty for the walls serves as the basis for further wall decoration, because. it has the following characteristics:

Differs in larger grain in comparison with finishing solutions. Because of this, it is rather difficult to grind. The surface of the frozen starting mixture is rough. It is mainly used for starting wall finishing, leveling and filling small cracks.
It is applied in works with brick and concrete surfaces.
Has a high drying rate.
Does not crack over time, creating a solid base for any kind of finishing materials.
It can be applied in layers from 0.3 to 2 cm.

Covering the starting putty can be the penultimate stage in the repair of walls. However, given that such a surface will be quite rough, the final coating can be wall panels, dense heavy wallpaper, but not a thin wallpaper or paint.

Consider a few specific examples of starter mixes that are very popular with buyers:

Scanmix TT (Finland). Universal starting putty. It has a cement base, applicable indoors and outdoors. This putty is waterproof, frost-resistant. With the maximum possible layer of 2 cm, complete hardening occurs in a day. The cost is low (from 280 rubles for 25 kg of dry mix). Possible shrinkage of the mass during drying.
Knauf HP homepage (Germany). On a plaster basis. It is used for finishing interior walls where there is no high humidity. Possible layer thickness - from 4 to 15 mm. Full hardening occurs within a day. The mass does not shrink. The coating has a high degree of strength. The cost is about 360 rubles for a package weighing 30 kg.
Ceresit CT 29 (Germany). Universal putty (internal, external works). It is not recommended to apply in rooms with a high level of humidity. During puttying and drying, the ambient temperature should be in the range of +5 ... +32 degrees. However, further operation is possible even at sub-zero temperatures (up to -50 degrees). The rate of complete hardening is high - from 10 to 15 hours. The composition contains a polymer (microfiber), which causes high strength. 25 kg of dry mix costs from 430 rubles.

Finishing putty for leveling walls

Finishing putty for walls is intended for the final stage of preparing the base for finishing. It can be described using the following characteristics:

Creates a smooth surface thanks to its creamy consistency.
It is used only on a pre-leveled surface.
It is applied in a thin layer (from 0.1 to 0.4 cm). In other cases, the solution shrinks, cracks appear. In addition, a thick layer is difficult to smooth over the surface, because. mass can float.
It is easy to sand, and after the complete drying of the finishing mixture, a large amount of dust is formed.
It is less durable than starting mixtures.

Here are some examples of finishing mixes:

Knauf HP finishing (Germany). On a plaster basis. Recommended only for rooms with a normal level of humidity. Full hardening occurs in 15-24 hours. One of the most durable putties among analogues. However, large hard particles often come across in the mixture, which create a certain difficulty in work. The cost of a bag weighing 25 kg is about 390 rubles.
Ceresit CT 225 (Germany). Has a cement base. The final coating becomes durable, smooth, has a white color. The main disadvantage is the high cost (790 rubles for 25 kg).
Scanmix LH Standard (Finland). Based on polymers. The mass does not shrink. Universal, i.e. suitable for all types of rooms. The coating has an ideal whiteness, so the finish surface can not be painted. It is quite expensive (the average price is 900-1000 rubles per 25 kg).

Universal wall putty

In universal formulations, the main characteristics of the starting and finishing masses are combined. Those. it can be used with slight unevenness of the wall surface, while after drying a fairly smooth surface is formed. The cost of such material is somewhat higher. But, despite this, the quality of the universal layer is significantly inferior to the classical technology using start and finish.

Among the many universal putties, Kreizel 662 (Germany) stands out. Based on cement and lime. The composition is improved with additives that increase the resistance to operational loads. Applicable in rooms with any level of humidity. To avoid cracks due to shrinkage of the mass, the layer must be more than 3 mm. The cost is average (about 350 rubles per 25 kg).

Given the characteristics described above, many can answer the question of which putty is best for walls - “universal”.

Types of putties for walls according to the degree of readiness for use

In stores, putty is presented in two forms - dry mixes and ready-made solutions. Each type has its own advantages and disadvantages. Let's consider them in more detail.

Dry mixes for puttying walls

Powder mixtures for wall puttying are powdery compositions that must be diluted with water before being applied directly to the wall, mixing thoroughly by hand or with a construction mixer until a homogeneous consistency.

The advantageous aspects of dry formulations are as follows:

The ability to vary the density of the solution by adding different amounts of water.
Ease of solution preparation.
Convenient transportation.
Unpretentious in terms of temperature, long-term storage.
Lower price than ready-made solutions.

Disadvantages of dry mixes:

Small time costs for the preparation of the solution.
After kneading, such mixtures should be used quickly enough, for each specific product, the time frame is different - from 15 minutes to 1 hour.
It is recommended to knead in small portions.
During storage, the mixture is afraid of moisture. There is a high possibility of damage if water enters, because. packing - cardboard.

Ready-made solutions for walls

Ready putty for walls is packed in plastic buckets. As a basis, latex or dispersions of a new generation are most often used. It is stored in the form of a solution for a long time due to the fact that it contains special substances that do not allow it to solidify. You can apply the finished mass immediately after opening the package.

Advantages of ready mixes:

higher plasticity.
No need to use additional means to prepare the solution.
The closed ready solution can be stored long enough even after the first opening.

The main disadvantage is the higher cost compared to dry mixes.

Classification of wall putties by composition

Each manufacturer independently chooses the assortment of its goods, focusing on a particular consumer market. Due to the rapid progress in all spheres of life, there are many technologies for the production of putty mixtures that use different components. Ultimately, the composition directly affects the properties of the putty. Let us analyze in more detail which base can be used for the manufacture of putty, what properties, advantages and disadvantages are provided by different ingredients in order to highlight the types of putties for walls by composition.

Cement putty for walls

At cement putty for walls, the composition includes cement, sand as a filler and a solvent. For high-quality putty, only purified sand is used (a prerequisite is the presence of no more than 5% impurities such as clay). The different ratio of cement, sand and solvent determines the brand of mortar, on which the strength depends.

The positive properties of cement putty are as follows:

Not afraid of moisture.
It is applicable in rooms with high humidity, as well as for walls outside the room.
It has high strength after drying (the more cement and less sand, the stronger the layer).

Negative sides:

It is used as a base for finishing putty or decorative plaster.
The mass is subject to shrinkage when dried.
Low elasticity.
Not suitable for wood surfaces.
There are certain difficulties in working with concrete walls.
During operation, cracking is possible.
They have a gray color.

Gypsum wall putty

Gypsum putty for walls is an excellent option for finishing mortar.

Advantages of gypsum putty:

Breathable material.
Does not shrink or crack.
Creates ideally smooth surfaces, therefore, significantly reduces the consumption of paint, glue.
Suitable for the thinnest finishing materials, including paint.
High drying speed.
There are no smells.
Increased fire resistance.
Low price.
Components do not cause allergies.
Has a white color after drying.

Among the disadvantages are the following:

Does not withstand changes in temperature and humidity.
The surface is unstable to mechanical damage, chips may appear.
Narrow destination - only for interior decoration in dry rooms.

Polymer mixtures for wall puttying

Advantages of polymer mixtures:

High elasticity.
Durability of a strong covering.
Increased water resistance.
The mass does not shrink.
Wide scope.
The prepared solution can be stored for 12 hours.

The disadvantages of polymer-based putties are as follows:

Great cost.
Often there are low-quality fakes at a high price.

There are two types of putties with a polymer base:

Acrylic putty for walls. Universal option (internal and external finishing). Possesses the increased adhesion, weather resistance. Most often it is a finishing solution, because. With its help, you can easily create a perfectly smooth surface. Its feature is that the layer should be minimal - up to 1 mm. Applicable even to wooden surfaces. Not toxic. Mixtures have a long shelf life. A variety of acrylic putties - water-dispersion.
Latex putty. Applicable indoors only. Does not tolerate low temperatures well. Possesses good plasticity, durability, durability. Easy to apply. Does not emit odors. Can be applied to concrete, metal, plaster, drywall, wood surfaces.

Oil-adhesive putty for wall preparation

The basis for the manufacture of oil-adhesive solutions is drying oil.

The main advantage of this type of wall processing materials is low cost.

The limited demand for drying oil-based putties is caused by the following disadvantages:

Narrow application (only with materials based on drying oil).
It is not recommended to use them in residential premises due to the harmfulness of the components.
Coating durability.

In every case, it is better to use the useful advice of specialists. This also applies to the choice of putty for the walls. So, how to choose putty for walls - recommendations from professionals:

The best result will be obtained when using materials from the same manufacturer that are best compatible with each other, so the properties are combined and complemented.
Always pay attention to the recommendations of the manufacturer, which, taking into account the properties of all components included in the composition, describes the following: purpose (leveling walls or smoothing the top layer of a flat surface); operating conditions (exterior or interior decoration, operating temperature, humidity level); conditions of use (microclimate during work); putty consumption; combination with other preparatory and finishing materials.
To prepare the walls for painting, it is better to use ready-made mixtures, because. the quality of the finish layer will be higher.
Dry mixes are more suitable as a base for wallpaper.
When buying ready-made putty, ask the seller to slightly open the lid to assess the quality externally. In a poor quality product, hard inclusions can often be seen on the surface.
For interior work, choose putties without sand.
Under thin light wallpaper or paint, the finishing putty should be as white as possible so as not to affect the final color scheme of the wallpaper or cause the need to apply additional layers of paint.
In cases where it is rather difficult to decide on a product, give preference to a universal mixture to reduce the risk of making the wrong choice. Many experts choose acrylic putty, considering it the best putty for walls.
The highest quality products are made by European manufacturers.
Any putty may contain additional substances to improve properties, so carefully read the composition and recommendations for the wall material that can be treated with each specific solution.

Watch a video about choosing wall putty:

Buying putty for walls is not a problem. It is important to make the right choice, taking into account the characteristics of the room, the characteristics of the decorative coating and your own preferences in the cost of materials.

When the repair is nearing completion, you need to decide which putty to choose for the walls for painting. Construction stores offer a wide selection of finishing materials, including finishing putties of various compositions and from different manufacturers. Which is better? Before answering this question, it is necessary to understand what a finishing putty for painting is and what requirements it must meet.

Functions and quality standards of finishing putty

Represents dry mix or ready solution of white color. It is designed for the final alignment of the walls, allows you to hide minor surface flaws and increase the strength of the previous leveling layer. In addition to the scope, the finishing putty differs from the base putty in a smaller fraction of its constituent solid particles. In addition, any finishing mixture includes components that increase its plasticity, which ensures easier application.

What are the quality standards for finishing putties? Good putty for finishing:

has high adhesion (strongly adheres to the base material);
has no lumps;
easy to apply;
reliably masks the imperfections of the base surface;
does not move down;
does not crack after drying;
evenly dyed white.

White putty ensures the uniformity and brightness of the paint layer, so you should pay attention to its color.

Manufacturers offer a dry mix and ready-made putty, but which one to choose?

The answer depends on the skills of finishing work and the availability of tools. If you are doing wall decoration on your own, and you do not have a construction mixer or drill, it is better to purchase ready-made putty. It will cost more, but the preparation of the solution is a very laborious process.

Classification of finishing putties by composition

There are many finishes on the market. To understand which putty is best for the walls of your room, you need to get acquainted with the properties of different types of finishing materials. Depending on the components included in its composition, putty for finishing is:

cement;
plaster;
polymer.

Cement finishing putty is distinguished by high water resistance. This can be used to cover walls in rooms with high humidity - in the bathroom, toilet, sauna, swimming pool. Due to its water resistance, this type of putty is suitable for outdoor work: it is used when finishing the facades of buildings.

Working with a cement-based mixture is relatively simple: its curing time allows you to correct flaws in the application. The main disadvantage of this finishing material is the tendency to shrink, which leads to the formation of cracks.

Gypsum finishing putty is characterized by sensitivity to moisture: it is not suitable for use in damp, unheated rooms. Gypsum does not shrink, does not crack, forms a beautiful matte surface, and is environmentally friendly. Due to these advantages and relatively low price, this type of putty is most often used in the decoration of residential premises. Gypsum-based mortar can be applied in a thicker layer than cement. Gypsum sets quickly, so you need to quickly, which requires certain skills.

Polymer finishing putty began to be used relatively recently. Like gypsum, it is suitable only for use in heated rooms with low humidity, but it has a longer setting time. The undoubted advantage of polymer-based putty is its elasticity, due to which it is possible to apply a very thin layer (up to 0.2 mm) and easily distribute the material over the surface.

Another plus is the durability of the finished solution: it can be used within three days. This is the only finishing putty that allows you to get such an aesthetic surface that after its application you can refuse to paint. But the price of this finishing material is much higher than for finishing putties of other types.

Features of work with finishing putty

Finishing wall putty for painting includes three stages: priming, applying mortar and grinding.

Priming the base layer is necessary to increase adhesion and prevent moisture penetration. For this, an acrylic primer is used, which is applied to the walls on the eve of the finishing putty.

At the stage of applying the solution, you will need the following tools:

construction mixer;
narrow and wide spatulas;
plumb;
level.

Part of the dry mixture is poured into a clean container and the amount of water indicated in the instructions is added. This must be done carefully: compliance with the proportions determines the quality of the solution. The solution is mixed with a construction mixer or a drill with a special nozzle until the lumps completely disappear.

Finishing wall putty is a very responsible process if you decide to use paint as a decorative coating. The surface to be painted must be perfectly even, smooth and snow-white: this is why the selected putty must meet high quality standards. If wallpaper with a pattern is able to mask some of the shortcomings of the preparatory work, then the paint will reveal all the flaws.

A narrow spatula is used to apply the mortar to the walls, and a wide spatula is used to stretch it over the surface. How many times to apply finishing putty? It depends on the quality of the base coat. Putty until the ideal result is achieved, controlling the quality of the application of the solution using a level and plumb line.

At the grinding stage, it is better to work by hand, fixing sandpaper with grit P220-P280 in the holder: a rougher abrasive surface can nullify all efforts. The walls are sanded in a circular motion until the stripes from the spatula disappear completely.

The basic techniques for finishing putty are presented in this video.

A few important rules

It is important to remember that putty for walls for painting requires several conditions to be met:

the final layer of the finishing putty should not exceed 2-3 mm (if this requirement is not observed, there is a danger of peeling);
the next layer of the solution can be applied only if the previous one has dried well;
the thickness of the finish layer should be greater if you plan to use light paint;
it is possible to grind the surface only after it has completely dried (its time depends on the composition of the mixture and ranges from 6 hours to 2 days);
after grinding, dust must be removed from the surface;
before painting, a primer is applied to the last layer of putty (it will bind the remaining dust particles and ensure uniform paint application).

You can endlessly bring walls to perfection. How to determine that the finishing putty is completed? A portable lamp or flashlight will help you evaluate the quality of work: by illuminating the walls from different angles, you can see the slightest bumps and scratches. If all the shortcomings are eliminated, you can apply the last layer of acrylic primer and start painting in a day.

The choice of finishing putty: prioritizing

The question of which finishing putty is the best has no answer: any composition has its advantages and disadvantages, limitations in use.

It is not necessary to choose putty materials from the most famous manufacturers.

It is important that the selected putty matches the conditions of the room in which it will be used: this is necessary for the qualitative preparation of the walls for painting.

For facade work, unheated rooms, bathrooms or kitchens, only cement-based putty is suitable. Using it for finishing living rooms, it must be borne in mind that cracks may form over time, and the coating will be inferior to other compositions in terms of texture smoothness.

In residential areas with low humidity, it is better to give preference to finishing compositions on a gypsum or polymer base. If the base layer of putty has relatively serious flaws, a gypsum-based mortar should be used: it allows the application of a thicker layer (respectively, material consumption will increase). If you have an almost even base coat, you can bring it to perfection with a polymer finishing putty. Its high cost is offset by low consumption and ease of application.

When selecting finishing materials, their compatibility should be taken into account, therefore it is desirable that the finishing one has one manufacturer.

The final choice will help the calculation of the required amount of materials, which depends on the thickness of the applied layer and the area of \u200b\u200bthe walls.

First of all, it is necessary to determine the subject of consideration. Putty - a powder or paste mixture for filling irregularities on surfaces intended for finishing work. The word comes from the German Spachtel (scapula).

There are many types of spatulas. For their manufacture, many different materials are used: from glue to drying oil. There are two spellings, readings and pronunciations of this word: putty and putty. The first refers to professional vocabulary, and the second is commonly used.

To date, there is a fairly large selection of materials for leveling surfaces.

Composition of mixtures

All commercial putties have approximately the same preparation formula:

film-forming substances. Like: various ether, epoxy, phenol-formaldehyde and alkyd resins.
Fillers. This role can be played by gypsum, chalk, mica. In special types of material, more specific substances may be used.
Various pigments: ocher, zinc white.
Binder. Many compositions play this role: from PVA glue to special epoxy resins.

Types of putties

Modern builders and repairmen know 9 types of this material:

The use of putties for interior decoration

Regarding the interior decoration of the premises, the following types of putties can be distinguished: starting, finishing, specialized and universal.

Starting lineups are the most common. It is very important to choose the right starting coating, since it is on it that the subsequent finishing will be applied. For this type of material it is important to have good adhesion to the substrate, to have sufficient strength and maximum filling and leveling of defects. The use of gypsum putty as a start is very common.

For long-term work, I use compositions with a lifespan of 8 to 24 hours.

Need to know!
The life of the composition is the time from mixing / opening the package until the moment of drying. Mixing the composition is called the process of adding a solvent. In difficult or special situations, the use of compounds with a lifespan of half an hour to three hours is envisaged.

Mechanization of coating application will help to significantly reduce the consumption of putty and time. With the help of mechanized means, it becomes possible to process 400 m2 of surface per shift.

The material can be applied to the wall not only manually, but also mechanically.

Finishing compositions are designed to create a surface completely ready for subsequent finishing. The choice of a specific type of finishing composition depends entirely on the method of finishing the walls. Putty for painting should have a minimum filler grain radius. The best types of material have a filler fraction of no more than 100 microns. Such materials give a perfectly smooth surface that does not require grinding. When choosing materials for wall decoration, it is very important to have an idea of how they will interact with each other. Incorrectly matched topcoat or topcoat to the paint can cause peeling, staining, or blistering of the finish.

Important!
For applying wall putty under wallpaper, the size of the filler fraction is not so critical. From 150 to 250 microns is the best option. A smaller value is best used with thinner wallpaper or fabric materials for pasting. If the future coating is thick enough, then the entire wall putty under the wallpaper may be limited to the starting coating.

Specialized putties are designed to perform specific tasks. For example, putty for sealing joints between gypsum boards without additional reinforcement or plastic putty for filling moving cracks. Due to the narrow specification of the application, the manufacturer specifies the exact area for each specific type of special putty.

Universal putties are three in one. They combine the properties of starting, finishing and even special putties. This is convenient for non-professionals. There is no need to get lost in choosing the most suitable option, you can take one type and perform all the work with it - from small filling of cracks to complete repair of the walls. In addition, the use of one type instead of three helps to reduce the consumption of putty.

Car repair

No repair of a damaged body can do without a special epoxy or polyester putty. The procedure for coating a car body is practically the same as coating walls with putty. Same start and finish layer. It differs only in putty for body coloring. In the case of the body, another layer of finishing putty appears, filling microcracks and irregularities.

putty market

The situation on the building materials market is very interesting. On the one hand, in the minds of the layman, foreign manufacturers are more popular, whose names are on everyone's lips: "Tikkurila", "Semin Sem", "Knauf" and other inhabitants of neighboring Europe. On the other hand, the domestic market is filled with high-quality locally produced products, the same Tex putties.

Russian materials under the Tex brand are gradually conquering the market

In any case, how many people have so many opinions. Therefore, the choice between Finnish guests and Russian Tex putties is a personal matter for everyone.

Putty, as we have seen, is not just a material, it is the concept of a material. There are a huge number of types of putties, each of which perfectly copes with its tasks.
