Most residential and public buildings under construction are finished plaster mixture, which is called “wet”. Facade putty is a weather-resistant putty for exterior use. Used for final leveling of walls before application decorative covering. It is distinguished by its special strength, moisture resistance, and frost resistance. In this article we will tell you what façade putty should be, how to apply it correctly and choose it.

As mentioned above, facade putties must have certain qualities, namely high frost resistance. A high-quality putty should contain the following components:

• Gypsum or cement.
• Plasticizer.
• Modifying additives.
• Mineral fillers.

Very often, when finishing the facade, putty with a high content of glue, soap, gypsum and chalk is used. Depending on the type of work, we select different types of this material, the most popular are: combined putty, facade cement, latex mixture, facade acrylic and others. A universal option is considered to be a combined facade putty, which is excellent for leveling the surface; in addition, it allows you to cover even very large defects and defects. The combined putty, even after many years, will not crumble and will not flake even in the cold season.

The shelf life of façade putties is limited to six months. Don't stock up on it in advance!

The most popular types of facade putties

To choose the right putty, you need to learn more about its composition and properties.

Latex putty is not suitable for facades

It is one of the most popular in its segment, suitable for any surfaces in the interior, but not suitable for facades. This material is sold in 25 kilogram buckets. We will mention it only so that you know and do not get confused in choosing.

Adhesive putty

1. Possibility to mix with pigment compositions to change color. This will make it possible to do without painting the surface, and any mechanical damage to the walls will not be so noticeable.
2. Putty consumption per one square meter. Consumption usually depends on the thickness of the laid layer and the filler. The smaller the thickness, the more economical the material is.
3. The putty must be compatible with any.
4. The time period for the mixture to harden.
5. Plasticity of the material.

How to choose winter façade putty

What are the main properties of winter façade putties - the ability to work with low temperatures ah and resistance to cracking when drying. For winter, you can use both acrylic and cement putties. But on the manufacturer’s packaging there must be a corresponding entry - “winter series”. Of course, such putties will be a little more expensive than usual, because they have added special construction chemicals that improve setting at low temperatures.

Which façade putty is waterproof?

Cement putty is waterproof. It is used not only for facades, but also for screeding floors and finishing bathtubs in the house. Therefore, it does not require additional polymers and hydrophobic substances, such as gypsum.

Gypsum putty is not at all suitable for facades and can only be used in interiors, and not in wet rooms. Of course, marketers and technologists teamed up and found a way to use it in wet rooms, adding those same water repellents to it.

Does façade putty protect against fungus?

Those façade putties that contain antistatic and antiseptic agents protect. It is better, of course, to treat the effect rather than the cause. And prevent the formation of fungus on the facade. Mold on the facade is always the result of dampness, which for some reason appears and for some reason does not dry out. It is better to think in this direction to exclude the causes of fungus.

Important! Remember that each subsequent layer in the wall structure must be more vapor permeable than the previous one. If this principle is violated, problems with fungus cannot be avoided by any antiseptics. They simply won't cope.

Which façade putty is suitable for painting?

Any. Both acrylic and cement, your choice.

Which façade putty is best for use on plaster?

Any facade putty is suitable for working on a plaster facade. It will be easier to apply acrylic, but it is more expensive than cement. Acrylic is more elastic. Cement is more economical. The choice is yours.

What to do next after plastering the facade walls

Paint, plaster, decorate with panels based on insulation, or use the latest technology hinged ventilated facade. Curtain facade– this is cladding with siding, plastic or metal panels, porcelain stoneware, wood or stone panels. In general, after puttingtying the facade, proceed to the design of the exterior.

How to properly putty a façade

Let’s make a reservation right away: there are two ways to putty a facade: manual and machine. The machine is used to work with large volumes to increase the speed of work. For a private home, of course, this is irrelevant. By the time you get used to the machine, the facade will already be finished, and the material will be used twice as much as with the manual method.

Therefore, it is advisable to apply the material on our own, using a spatula or grater. Regardless of the method of applying the material, first of all, the base must be prepared: the surface is cleaned of dirt, dust and oil stains, then priming is performed, which is necessary to ensure adhesion of the materials.

The finished putty material is mixed before work. If there are any on the surface significant defects, you must first eliminate them by filling the gaps and cracks with putty. After the “patches” are completely dry, a continuous layer of material can be applied. If necessary, apply several layers. To achieve an excellent result, it is recommended to sand the finished surface.

Advice. Do not putty the façade in high humidity or hot weather, when the surface gets very hot, this greatly reduces the quality of the finish. Because the putty takes some time to dry.

Consumption of façade putty per 1m2

1. Starting and finishing putty.
2. Universal putty.

Consumption per 1 m2 of starting and finishing putty

Starting putty is needed to seal cracks and level out small differences. It is impossible to accurately calculate its consumption, since it is necessary to start from the condition of the wall. But to grout a medium crack, you will need a layer of approximately 3-4 mm per square meter. Perhaps cover the entire wall starting putty and you won’t have to, so it makes sense to estimate the area to be putty.

To cover one square meter with a 4 mm layer of starting putty, you will need four kilograms of dry mixture. Usually the dry mixture comes in 20 kg bags.

The consumption of finishing putty per square meter is less than the starting putty. Largely due to preliminary priming of the surface. You can focus on 1 mm.

To cover one square meter with a 1 mm layer of finishing putty, you will need 1.2 kg of dry mixture.

Consumption per 1 m2 of universal putty

The declared consumption of universal putty by manufacturers is lower than the combination of starting and finishing putty separately. Typically, it is 1.5 kg per square meter for a layer of 1 mm. Manufacturers always indicate consumption on the packaging.

How many mm thick layer you need will all depend on the condition of the surface to be coated. Let's focus on the middle layer of 2 mm.

To cover one square meter with a 2 mm layer of universal putty, you will need 3 kg of dry mixture.

It is justified to use universal putty on more or less smooth and crack-free surfaces.

Stages of work execution

It is recommended to finish the façade after the foundation has settled. As a rule, this process has a duration of about a year. Processing walls requires some effort and effort; you must be fully prepared for the fact that you will have to do at least two layers of mortar to get the desired result.

It will be impossible to get by with just one layer; even a qualified specialist will not be able to cope with such a task. Best Temperature for outdoor work is from 9 to 20 °C, permissible humidity air should not exceed 80%.

The process of applying putty occurs as follows:

1. The surface is cleaned of excess dirt and old finishes.
2. A primer is placed on the cleaned surface; it must dry before further operation. It is better to prime the surface in two layers.
3. Next, depressions, dents, and cracks are removed. After which the material is allowed to dry.
4. The putty is applied evenly to the walls and then carefully leveled. It is better to use two metal spatulas as improvised means. different sizes and a construction float. It is important to note that façade material must be used in pure form, it must not be mixed with paint or other additives.
5. After the first layer of putty has dried, it must be primed in order to improve adhesion to other layers.
6. The starting putty is applied layer by layer until the surface of the facade is completely straightened. Each layer is applied only after the previous one has dried.
7. At the last stage, finishing putty is laid on top of the base material.

Expert Experience

According to many construction companies, the best option putty for building facades is one that contains cement. This material is quite easy to apply to the surface of the walls and has high strength after drying. If you are going to repair the facade, then you need to understand that each subsequent layer must be more vapor-tight than the previous one. Otherwise, fungus and mold cannot be avoided. So that you don’t have to worry too much about selecting each layer, choose all the elements from the same manufacturer. This guarantees you compliance with the principle of vapor permeability when finishing the facade. This way you can completely protect yourself from incompatibility of materials.

Happy finishing! Share your comments and experiences with façade putty.

Almost any construction project cannot be performed perfectly. And in order to give the building a perfect and finished look, it is necessary to carry out external work using facade putty. With its help, you can prepare the surface for decorative coating.

Often this material is called a little differently - putty, but both of these concepts are equivalent. Putty for external use has several purposes:

• Surface leveling for finishing.
• Facade protection from harmful effects environment.
• Strengthening materials.

Currently, putty can be purchased at any hardware store. It is sold in two types:

1. Ready mix. Located in special containers, volume may vary significantly. Very convenient for unscheduled work, or if long transportation is not required. Has restrictions on storage time. Can be used gradually after opening the container. Afraid of frost.
2. Dry mixture. It is used for large-scale work, as it costs much less. Can be transported and stored for a long time. Cannot be stored in damp areas.

Types of putties for facade work

Mixtures for facade works differ based on their tasks. The following groups are distinguished:

1. Main. Consists of large fractions. Used for initial application. It smooths out minor irregularities and differences. With its help, cracks and chips are repaired. Well suited for objects that were built from bricks and foam blocks. Very durable, does not react with chemicals. Can be applied in a layer of up to two centimeters. The solution for work should have the consistency of sour cream. In a more liquid state, the material consumption increases, it takes longer to dry, and the desired result cannot be obtained.
2. . Consists of a fine fraction. Apply to the prepared surface. Serves exclusively for minor leveling. Hides small cracks. The application thickness does not exceed 3-4 mm. The solution is prepared in a more liquid form than for the main (starting) one. In both cases, an acrylic mixture works well.
3. Putty for decoration. Serves to create textured elements on the surface.
4. Putty for wooden structures. Protects objects made of wood or with wood cladding from climate influences.

Facade putties vary in technical specifications. Each of them plays its role in protecting the building. Correct application and alternation makes the object durable.

This material must have the following qualities:

• resistance to high humidity and frost;
• elasticity, with slight shrinkage no cracks should appear;
• must have pores that allow the surface to “breathe”.

Types of putty based on the base

Putties have different compositions. But it all depends on the component that is the main one. It is he who gives her the qualities that are necessary. But in addition to positive qualities, there are also negative ones. The development of technology has made it possible to create new types of materials, for example, acrylic putties. So, other polymer putties appeared. They began to possess a large number positive qualities, but have not yet become available. Below is a table that clearly shows the types of mixtures.

The most commonly used putties are of two types: cement-based and acrylic-based. The first is chosen because of its satisfactory characteristics and low price. The second because of its positive qualities, which are far superior to the first.

Cement-based putties

Having good strength, this material does not form cracks after drying. The composition for initial work includes sand, which is pre-crushed. The final composition includes:

• finely ground limestone;
• ground quartz sand;
• microcalcite.

IN modern composition contains special chemical additives that improve its characteristics. This putty has different shades. There was a white cement putty available, but it was no longer available.

When choosing such a material, you need to be guided by the following aspects:

• what brand of cement is used;
• what is the compressive strength?
• how it interacts with the material that will serve as the basis;
• Excellent for concrete work.

Acrylic based putties

Such putties include the addition of special polymers. They can be used for all types of facade finishing. Such mixtures are already ready for use; they do not need to be further diluted with water. If desired, they can be tinted, but to do this you need to make sure correct selection color scheme Apply in thin layers.

Such mixtures have many advantages:

• long service life, this is ensured by the addition of chemical elements;
• they are not afraid of shrinkage of the building, they do not form cracks, but adapt to changes;
• short drying time;
• no pungent odors or discharge.

But these putties also have their drawbacks. They react with some materials. Therefore, you need to carefully monitor what surfaces they can be used for.

How to prepare the solution

If ready-made mixtures can be used almost immediately, then you will have to tinker a little with dry ones. Although the process of preparing the solution itself is not that complicated. The whole point is that the powdered putty needs to be diluted with water and mixed. The kneading must be thorough; for this it is better to use a drill with a special attachment. Each solution has its own mixing time. It is indicated on the packaging. It is best to follow the instructions, then you can be sure that the mixture will turn out to be the desired consistency.

The amount of solution is prepared based on the volume of work. If there is excess leftover, it will not be possible to save it. The norm can be determined based on the data that the manufacturer must place on the packaging.

Work order

It is better to begin all work when the building has completely settled. This is the only way to avoid unwanted cracks. This should be especially borne in mind when using cement façade putty. If the surface has large unevenness, you will have to apply several layers. The drying time depends on the putty used. The acrylic mixture dries faster. Weather conditions also need to be taken into account.

Sequence of work:

1. The walls are cleaned of dirt.
2. The surface is primed.
3. Large defects are repaired separately.
4. Puttying of the facade begins. Apply required quantity layers. Each layer must dry completely.
5. The last layer after application is sanded.

The choice of the right putty for the facade depends on the work being performed. All parameters must be taken into account to achieve the desired result. It is very important to follow the instructions, then you can be sure that the treated surface will perform the functions required of it.

Puttying walls is an integral stage of both internal and external finishing works, because it is this process that allows you to level the surface as efficiently as possible and prepare the base of the walls of the house for finishing. Unlike putty intended for indoor repairs, more serious requirements are put forward for the exterior of this material, since high and low temperatures, humidity and, of course, frost, characteristic of our climate zone, directly affect the walls of the building. Therefore, this article will be devoted to the consideration of the features of putty for external work and the technology of its application.

Purpose of putty for exterior use

Putty - This is a special mixture with which various types of defects are eliminated, seams, chips, small and more significant cracks and roughness in order to create the maximum flat surface walls built using materials such as brick, concrete, foam concrete, gypsum, stone and any others.

As a rule, putty for exterior use includes components such as cement, special mineral and modifying additives, as well as plasticizers. So, exactly these ingredients give the necessary properties to a material intended for outdoor use. To the undeniable benefits putties can be classified as:

• environmentally friendly material and safety for human health;
• durability to various weather conditions in the form of high and low temperatures, their sudden changes, as well as precipitation;
• absence of unpleasant and uncomfortable odors;
• resistance to ultraviolet rays and surface fading;
• enough high plasticity rates;
• The vapor permeability characteristic of the material allows the walls of the house to breathe;
• possibility of subsequent painting or purchasing ready-made color finishing mixtures.

Putty for external work is usually divided into two categories, namely starting and finishing. The first consists of coarse-grained components and is intended for rough surface finishing. Due to the fact that the cost of this material is much less than finishing putty, it is recommended to level the walls as accurately as possible using it. In addition, higher adhesion rates contribute to better adhesion to materials such as brick, concrete, limestone, etc.

Finishing putty, having fine-grained structure, is used for final surface treatment and elimination of small irregularities that were not hidden by the starting layer. Has higher strength and, if necessary, wider color scheme. On construction market The putty is presented both in dry form and in ready-made form, which does not require prior dilution with water.

Types of putty for exterior use, their advantages and disadvantages

Depending on the production technology and the components of the mixture, there are the following types of facade putty:

Preparatory work before puttingtying external walls

First of all, you need to choose the right day with favorable weather conditions. The best option for working with this material it is considered air temperature condition within 5−25° C and humidity not higher than 70−80%. Wet layer The putty applied to the wall should not come into contact with direct sunlight, a humid environment, or low temperatures.

Tools And materials You won’t need too much, but still the list of preliminary targeted purchases should consist of the following items:

• capacity in which the solution will be mixed;
• for convenience, you can use drill with mixer attachment for mixing the solution;
• respirator and mask necessary in the process of grinding the surface of some types of putty;
• roller or brush for applying the primer mixture;
• metal spatulas, the width of which, as a rule, ranges from 450 to 600 mm;
• grater or diamond mesh for grinding the surface;
• primer deep penetration;
• starting and finishing putty.

Preparatory work includes cleaning the surface from various contaminants, poorly adhering layers of old finishing, as well as removing greasy stains, possible traces of fungus and other types of dirt.

Features of the process of filling external walls

Applying putty to the wall is not particularly difficult, but at the same time it is quite fine work, the approach to which should be based on patience, accuracy and attentiveness. After all the above have been carried out preparatory work you can begin the process of filling the walls, which is divided into the following steps:

This completes the filling of the external walls of the house. The most important rules that must be followed include, firstly, the complete drying of each layer of putty, and secondly, maintaining proportions when mixing the solution. Everything else depends on your desire, skills and financial capabilities.

Video of wall putty

Choosing as facade finishing painting the walls, they must be properly prepared for applying decorative coating. What material should I choose for this?
The best cement cerizite putty for exterior work is in the form of a dry mixture or a ready-made composition for polymer based. What are their advantages?

The first rule when choosing suitable composition: on its packaging there must be a mark indicating the area of ​​application. In our case, facade putty is necessary (see Facade putty - features of selection and use). Not just moisture- or frost-resistant, but intended for outdoor use.
No gypsum-based mixture is uniquely suitable, since gypsum absorbs moisture very well and a coating made from it will not last long.

Composition and purpose

But external putty for walls can be different, both in composition and in purpose. As for the composition, the choice is limited to mixtures based on cement or polymer resins, i.e. those substances that have high strength after drying and perfectly withstand the most adverse atmospheric influences.
The difference between them is as follows:

• Polymer putties are available in finished form, their price is higher, but they are also easier to work with.

• And cement ones need to be prepared immediately before application, stirring with water and independently determining the optimal consistency.

Which one to choose is up to you. This depends on financial capabilities and experience in puttying. The ready-made mixture is, of course, more convenient.
Also, facade putty, regardless of composition, can be starting and finishing:

• The starting one has a coarser, coarse-grained structure and is used for the initial, rough leveling of surfaces. It has high adhesion to concrete, lime, brick and other mineral substrates.
  Fills joints in masonry well, deep cracks, chips and other irregularities. The thickness of the layer can vary from a few millimeters to several centimeters.

Please note. It's better to apply several thin layers than one thick one - the quality will be higher. In addition, not being a specialist and doing this kind of work with your own hands for the first time, it is quite difficult to maintain the same coating thickness over the entire area the first time.

• Finishing putty for exterior work has a fine-grained structure and is intended for final leveling of the surface, making it smooth. Although there are special decorative mixtures with additives from coarse grain quartz sand or marble chips to give the facades a relief texture.

What properties should the material have?

Puttying the outside of a house is intended not only to give it a neat and aesthetic appearance, but also to protect the walls from all the influences to which they will be exposed during their entire service life.
These are primarily natural natural phenomena: rain, snow, high humidity air, sun rays, frost, sudden temperature changes, etc. In addition, the facade experiences greater mechanical loads than interior walls.
We should not forget about maintaining a healthy microclimate in the house, which largely depends on exterior finishing walls
Based on this, we can conclude that facade putty should have the following properties:

• Water resistance;
• Frost resistance;
• Vapor permeability;
• Durability;
• Elasticity and low degree of shrinkage so that cracks do not form;
• Environmentally friendly.

It is especially important that the finishing putty of external walls has these properties, since the main load falls on it.

Features of application

There is hardly any need to describe in detail the process of puttying facades - the technology is no different from similar finishing of internal walls.
Let’s just recall the main points and recommendations that any instructions for using these materials contain:

• Before puttying, the base must be cleaned of loose old coating, deposits of masonry mortar, dirt, and traces of oil;
• Under each layer of the solution it is necessary to apply a deep penetration primer to increase adhesion;
• You can only work at air temperatures not lower than +5-10 degrees and humidity not higher than 75-80%;

This is important! Extreme heat above 25 degrees is also not best time for finishing: putty dries too quickly, which can lead to cracking. This is most likely to happen if you apply it to walls heated by the sun.

• It is necessary to adhere to the layer thickness recommended by the manufacturer and not exceed it;
• Do not mix putty with other building mixtures;
• Until the finished surface gains strength and hardens, it must be protected from exposure to sunlight and rain by covering it with film.

Conclusion

Facade putty is used for finishing walls, window and door slopes. It is often used to level foundations in rooms with high humidity.
The most common way decorative finishing for putty – this is painting facade paints. It is often combined with cladding individual elements and corners of buildings with natural or artificial stone.
The video in this article will tell you more about this material and its application.

The walls of my friend’s house were erected, and Vadik called me to once again become his teacher. Facade putty was purchased different varieties. My house builder wanted to know how it was different and how to apply it correctly.
We began finishing the façade with a debate about how to spell the word “putty” correctly, with the letter K or T. I argued that the test word was “putty.” My learned friend found its meaning in German- shoulder blade. Many decades ago, having come to Russia, an unknown word was repeated, as it was perceived by ear in a foreign sound - putty. Even the spelling dictionary accepted both words.
A sales consultant at a hardware store judged us. He had both options on his labels. He said with a straight face that the action of leveling surfaces is putty. And the mixture itself, especially from German manufacturers Knauf, Pufas, Rudel and others, is putty. In general, this is plaster for exterior use. The putty is produced as finishing facade.

Putty is a plaster for exterior use.

Why putty the facade of a building and the procedure for working

The materials from which the walls are laid are mostly hygroscopic. Brick and aerated concrete, wood absorb moisture. The solution also gets wet. At the same time, they lose their property of low thermal conductivity and the houses become damp and cold. In winter, the water freezes and the crystals destroy the wall from the inside.
To protect walls from rain and sunlight, façade putty is used. The outer layer of finishing has low thermal conductivity and acts as insulation. At the same time this decorative decoration buildings.

The façade is finished in several stages:

1. Installation of thermal insulation if additional insulation is being done.
2. Cleaning the surface from dust and coating with a primer.
3. Carrying out work on rough leveling the surface with starting putty, mainly cement.
4. The final finishing of the walls uses a waterproof finishing mixture; in the northern regions, a frost-resistant one.
5. Decorative finishing and painting.

Facade putty is also a decorative decoration of the building

Need to know: B major cities, historical areas, on the territory of architectural monuments, before finishing the facade, it is necessary to issue a Color Passport. Colors and decor must correspond to those specified in the document.

Produced façade putty in several stages. Large defects are smoothed out first. Then the finishing putty is applied. The list of works for finishing the facade of a house may include painting. Material consumption is calculated per 1 m2 and depends on the size of the irregularities, the characteristics of the mixture itself, and its components.
Preparing walls for exterior work for all types of façade putties involves cleaning the surface. All areas where the solution does not adhere well and may crumble are removed. The protrusions are knocked down. It is necessary to remove all dirt and sweep away dust. To increase adhesion, it is advisable to prime. The exception is cement putty, under which the wall can simply be slightly moistened.

Facade putty

Required qualities of façade putties

The putty should:

• Have high adhesion and adhere to any material from which the walls are made;
• be plastic;
• easy to level with a spatula;
• harden without cracking;
• turn into a solid mass;
• easy to clean;
• good paint coverage.

Puttying the facade

Facade putties have additional characteristics:

• waterproof;
• frost-resistant;
• UV protection;
• repels dust.

The main qualities that facade putty has are aimed at protecting the walls of the house from moisture and temperature changes. The building maintains a microclimate due to the low thermal conductivity of the protective layer. The walls breathe and remain dry because dew does not form inside the wall. UV protection lasts for a long time bright color paints. The walls do not require constant cleaning of dirt, since it does not stick.

Putty on cement based

Specifications include:

• time of ripening and complete drying;
• thickness of the applied layer at a time;
• material consumption per 1m2;
• simple and combined;
• for use inside and outside;
• dry mixtures and ready-to-use formulations.

Cement-based putties

On initial stage finishing the walls from the outside, puttingtying the facade is done with a cement-based composition with sand. Lime, gypsum, synthetic fibers and other materials can be added as plasticizers. To give decorative look, the putty is painted. Color selection is limited. More often they use whitewashing of walls and finishing with synthetic materials.
The main manufacturers of cement putty are Knauf and Staratel. They release large selection finishing materials, single-component and mixed. Consumption per 1 m2 depends on the thickness of the layer and the unevenness of the surface. It is indicated by the manufacturer on the packaging with optimal characteristics for the work of this finishing material. Packaging of the dry mixture is usually done in paper bags 20 kg each.
The disadvantage of cement putty is its hygroscopicity. Without a protective layer of synthetic, acrylic, silicone mixture of Staratel, Rudel, Pufas and Knauf, it is quickly destroyed by rain and frost.

Grain size of cement plaster

Acrylic putties for exterior use

For façade protection work, acrylic plaster is produced:

• for leveling walls;
• finishing color and for painting;
• decorative

It is applied in a layer of up to 8 mm and its consumption per 1 m2 is significantly less than cement. The main component is acrylic, which is approximately 2 times lighter than cement and sand. Available in ready-to-use form. One package is enough to finish 15 - 17 m2.

Acrylic putty

Knauf products

The German company Knauf is known as a supplier of building materials for all types of finishing work. It produces multi-component putties. The most popular acrylic universal. The addition of gypsum and mineral fibers makes it plastic and water-resistant. The walls beneath her are breathing. Consumption per 1m2 is small. Due to this, it is more profitable than cheaper cement mixtures.
Knauf acrylic decorative mixture is used for finishing facades and interiors. A large palette of colors allows you to create original finishes with unique combinations of tones and pressed patterns.

Putty Knauf

Putties from Prospectors

The Russian company Prospector produces its products using German technologies. The composition includes domestic components and imported additives. Consumption per 1m2 is higher than that of foreign analogues. When recalculating the costs of finishing the entire facade, domestic products Staratel are more profitable than similar ones from Knauf. The cost of materials is much lower, since the cost of transportation and purchase of components is minimal.
Acrylic putty for exterior work by the company Staratel is produced with the addition of abrasive and fine granite crushed stone. She has high consumption due to heavy fillers. This Staratel mixture is used to finish the base and protruding foundation. It has high strength, moisture and frost resistance.

Putty Prospectors

If there is a large number of products different companies, there are mainly two manufacturers competing in the market: Knauf and Starateli. Construction materials both companies have high quality. Everyone makes their own choice. My friend made calculations based on cost, expense and economic benefit. I tried using different putties. I couldn't make a choice. Each putty has its own advantages and disadvantages.
