Quick-drying façade putty. Facade putties for exterior use. Why do you need façade putty?

Preliminary wall finishing and why it is needed

The average cost of a bag of dry putty is $14-15 (acrylic putty is slightly more expensive), and a small bag of cement costs less than $5, so it’s clear why it is necessary to pre-finish building facades. It is worth saying that cement-sand plaster has excellent adhesion to “wet” finishing building materials. This quality allows the plaster to be used with almost any type of building decoration.

Detailed video tutorial on the technology of installing a “wet” facade

Let's consider the entire set of “wet facade” complete with insulation. In this case, the walls are treated with a deeply penetrating primer so that the adhesive for the insulation has excellent adhesion to the coating. Then the foam insulation sticker is applied.

At the next stage, it is necessary to putty with starting putty, then glue the foam with glue like Ceresit CM-11 ( in fact, this is facade plaster). Reinforcement is also performed plaster mesh made of fiberglass. Thus, the wall covering is leveled, and the consumption of putty for the facade is minimized. This will significantly save money on finishing the house.

At the finishing " wet facade“There are some features and rules that allow you to minimize the consumption of expensive building materials. Using this cladding method, it is possible to perfectly decorate a building, create comfort inside it, and achieve good thermal insulation. Today, many people use this type of building decoration because it is very effective, economical and practical.

Finishing putties

Before applying the finishing putty to the walls, you need to know the features of this building material. When choosing, you need to take into account what the rough surface is like. better type putty, paste, dry powder, which can be either oil or adhesive, latex, acrylic or a combination.

Types of putties

Plasters differ in composition and texture

Today putties are mainly produced from silicone, silicate, acrylic, and they can also be combined. We can confidently say that the best putties and adhesives are from Ceresit. To perform puttying, use a metal or stainless steel spatula of the required width. It is also called a “facade spatula”, although it is also used for interior construction work. If necessary, the dried solution can be processed sandpaper or diamond mesh.

For putties used for exterior finishing, the main condition is high quality binding materials - acrylic, silicone and minerals, which are responsible for the hardness, impact resistance and moisture resistance of the putty.

It is worth saying that when working with these building materials there are absolutely no toxic odors, they are absolutely harmless to health.

Not any finishing putty, even the highest quality, can be used for exterior finishing. For example, the Vetonit powder mixture is excellent for finishing indoors, but it cannot be used for exterior finishing and even for finishing rooms with high humidity(for example, baths).

Application Features

Let's look at how to apply acrylic facade putty and dry mixture to already prepared walls.

When using dry putty for finishing, you need to take 1/3 of a bucket of water and pour the powder into it, then mix the mixture thoroughly using a mixer or a low-speed drill until the structure of the mixture reaches a consistency reminiscent of mashed potatoes. Then you need to wait until the mixture sits for 5 minutes and beat it again. Only after this the solution can be applied to the wall.

Finishing

When finishing the facade, the putty solution is applied to the wall with the usual wide spatula, but at the same time the mixture is pulled out of the bucket with a narrow spatula 7-15 cm, after which it is applied to the entire blade of a wide spatula. It all depends on the skills and skill of the worker. Someone treats the coating with one spatula so that after that there is no need to sand it. Some people use it in their work to speed up the application process. building code, and then finishes the plane with a spatula.

Finishing the façade with putty

The most important thing when finishing is not to stop the process of applying any plane, that is, any area on the wall should not have joints with the undried area that was applied earlier, so that after completion of the work there are no seams on the surface. Transitions to any protrusions on the wall, as well as the finishing of another wall, have nothing to do with this.

Both new and old houses require exterior decoration, and today the wet method of finishing the facade is increasingly used. In order to level the walls, seal the joints between slabs or bricks, and then apply the finishing decor with plaster or tiles, façade putty is used. The article will tell you about the types of this finishing material and the technology for working with it.

Leveling walls is one of the most labor-intensive and important processes in facade decoration. Without it, many other works on decorating the exterior of the house become simply impossible. For example, plastering a surface can only be done perfectly smooth walls, and overlaying and gluing insulation onto an unprepared base is impossible.

The words putty or putty come from the German word “Spachtel” - spatula; the use of both options is quite acceptable, so in the following story you will be able to see both. In addition to leveling, putty performs another important function - sealing potholes and cracks in the wall. This is what it was originally used for.

Requirements for facade putty material

Based on the purpose of façade putty, it has a number of requirements that must be taken into account when purchasing.

Plastic. This property is characteristic of a high-quality solution. If the material does not have it, then there is a serious danger of cracking of the coating and its destruction from atmospheric vibrations.
Vapor permeability. The most important property of all types of facade finishing materials should also be in the putty. If it is missing, then the fumes will accumulate under the leveling layer and destroy it from the inside.
Moisture resistance. The ability to repel atmospheric moisture and not allow it to pass inside protects not only the putty coating itself, but also the facade of the house. Water can remain in the pores, and when frozen, expand and destroy it.
Frost resistance. Cracking from frost or seasonal temperature differences can also affect the main covering of the wall, so frost resistance is a very important quality for a putty mortar.

Materials and tools for puttying

Classification of putties by purpose

All putties for facade works are divided into two types: starting and finishing. Usually both are required. Before purchasing, inquire about the purpose and type of material so as not to buy unnecessary things. In addition, you need to decide which putty you need more and in what quantity.

Starting

The structure of this composition should be coarse-grained and have increased strength and high adhesiveness. It smooths out the main unevenness of the wall, seals structural cracks and potholes on the facade that require repair. Often used to eliminate uneven masonry or defects concrete walls. The composition can be applied in a fairly thick layer - up to 4 mm. For strength, particles of marble dust and lime are often added to the starting mixture. They give it the necessary elasticity and adhesion to the surface of the building. Most often, cement compounds are used for the starting layer, and polymer binders give the putty elasticity.

Attention! When purchasing a starting putty mixture, make sure that it is intended for facades. Compositions for interior work Use for external walls is unacceptable.

Starting putty

Finish

The final putty coating must be plastic, smooth, waterproof, and have good adhesion and strength. Most often, a mixture based on acrylic or silicate binders is used - they are more consistent with the goal of creating a smooth and uniform layer. Finishing putty is used to level the surface, and therefore the particles it consists of must be small.

The finely dispersed structure allows you to create a perfectly even base for future decorative coating. Experienced finishers recommend applying the finishing putty in several steps with a layer of about 3 mm. Do not use mixtures for leveling coating that are difficult to mix with colors. If in the future you are going to finish the walls decorative plaster or paint, it is better to tint the finishing putty in the appropriate shade, otherwise it may show through the main finish.

Types of facade putties based on the base

The building materials market offers a wide selection of putty compounds. Manufacturers, prices, types of mixtures can confuse any inexperienced finisher. Let's try to understand the main types.

Reinforcing mesh under cement

Cement

Such putties are considered the best for applying a starting layer and for filling cracks and potholes in the wall. Mixtures on cement based usually consist of cement, lime flour with fractions of 0.2 mm, quartz sand and marble dust. To improve the performance, chemical additives are added to it. Surface covered with starting material cement putty, looks perfectly smooth, but rather rough due to the coarse-grained structure of the material. The finishing cement putty has a finely dispersed structure and comes in several colors: gray, beige and yellow. White cement putty is almost impossible to find these days. Since its bleaching requires expensive compounds, which increase the cost of the finished mixture. It is available in the form of powders and ready-made mixtures in buckets. U liquid material there are also disadvantages.

The strong shrinkage of the dried mixture must be taken into account when sealing cracks.
If the liquid cement composition is applied in a thick layer, then the likelihood of cracking is very high.

In order to prevent the destruction of the cement coating, a reinforcing mesh is applied during the work.

Advantages cement compositions cover up their minor shortcomings.

Ease of use allows even an inexperienced finisher to work with it.
Cement is a durable material and guarantees high levels of frost resistance, density and weather resistance.
It has an affordable price, and therefore is very suitable for treating large surfaces, which is typical for building facades.

Important! Never mix cement putty with varnishes, paints and glue so that it does not lose its properties.

Grain of cement finish

When purchasing cement compositions, pay attention to the brand of cement, compressive strength and level of adhesion.

Plaster

Plastering with a gypsum mixture is one of the easiest ways to putty the surface of a facade. It is very easy to work with gypsum because it has a flexible, light structure and can be leveled well. Plastic makes it possible not only to easily level, but also to accurately form corners and perform other shaped work on the facade of a building. Positive aspects include good vapor permeability, frost resistance, smoothness, and easy coloring. The lack of shrinkage allows you to make a layer as thick as you like and apply it in one go.

But there is also negative aspects. If you live in rainy, humid areas, it is better to use gypsum to a minimum, as it absorbs moisture quite well and can be destroyed under its influence. On the other side, gypsum mixture It dries very quickly, so working with it under the scorching sun is not recommended.

By purchasing gypsum plaster, pay attention to the manufacturer. It is better to take proven brands. This way you will protect yourself from rapid damage to the facade and will be confident that the mineral additives contained in the composition are of high quality, which means the coating will last longer.

Gypsum plaster can be applied in one layer

Acrylic

These finishing materials There are starting and finishing points. Having all the necessary properties, acrylic mixtures can and should be used for facade work. They are sold ready-made, which makes their use even easier. Facade putty made of acrylic has good adhesive properties, but it is applied to a previously primed surface, since the putty layer is quite thin. The only disadvantage of acrylic mixtures is that the higher price compared to previous products does not allow it to be used over large areas as a starting layer. Most often it is used for finishing.

Latex and acrylate

These types of putty materials are designed for extreme conditions and therefore are used for outdoor work. They are even more moisture-resistant and frost-resistant than regular acrylic composition. Its durability and ductility have earned recognition from builders and finishers around the world. Latex and acrylate do not crack when dry and do not shrink. High adhesive properties make it possible to further strengthen the protection of building walls and make the bond with the subsequent decorative coating more durable. Latex mixtures come in the most different colors and therefore do not require additional staining. The thinnest layer of this composition forms an ideal finishing coat. There are such starting and finishing plasters, but too high a price is their main disadvantage.

Colored latex putties

How to choose the right putty for the facade

The characteristics of the putty and knowledge of which material is best to apply in certain cases will help you make the right choice.

When insulating a facade with polystyrene foam, polystyrene foam or polyurethane foam, it is better to use latex and acrylic texture. Use the same types of finishing mixtures when walls have poor permeability, for example, on concrete or metal.
If you live in cold zones where frost is a frequent visitor, then use a special frost-resistant putty.
Do not use oil-based products for facade work, but if you do purchase them, remember that you will only have to paint them with oil paint, since other paints will not adhere to drying oil plaster. But if your house is made of wood, then oil façade putty- not a bad choice.
Try not to use materials different manufacturers, price categories and types. If you started working with one, try to finish the process of puttying the walls with the same composition. Remember that the materials may not be compatible with each other! It is for this reason that it is better to immediately calculate the quantity of the product and assess your financial capabilities.
When calculating the amount of material, proceed from the thickness of the layer you need to apply. The thinner the coating, the less putty is consumed.

Dry polymer cement plaster mixture

Main manufacturers and prices

One of the most recognized manufacturers in the building materials market is Ceresit. Polymer-cement plasters from this manufacturer differ not only high quality, but also low cost. They are made from a cement-sand mixture with the addition of polymer additives and synthetic fibers for plasticity. These mixtures are different high vapor permeability, fire safety, long shelf life, cost-effectiveness. In addition, Ceresit putties differ from many in color. These are white mixtures, which is rare among cement compositions.
Synthetic plasters of this company are produced in finished form and meet the requirements of facade materials. Acrylic based acrylic resins, polymer silicate and polymer silicone compounds are used for finishing walls. They are characterized by increased resistance to deformation, moisture resistant and elastic. Properties acrylic materials you can study it from the photo in the table.
The global manufacturer of building materials, Knauf, has a strong position in the sale of plaster and putty compositions. It produces finishing cement mixtures in dry form, which significantly saves money on facade finishing. Packaging in 25 kg multi finishing cement mixture costs about 600 rubles.

Characteristics of acrylic putty materials Ceresit

The Prospectors company has proven itself to be excellent in the domestic market. It offers various facade mixtures at low prices with good quality. Weber Vetonit finishing putties have been in demand for many years. This dry polymer product for facade work has a low cost - about 600 rubles.

Finishing work

Technology for applying starting putty

The simplest and most popular method is beacon plaster.

We begin to plaster the wall. To do this, let's take right hand trowel, and in the left mortar and with a sharp movement we throw the mortar onto the wall. After this, use a trowel or grater to rub the putty mixture over the surface.

Grouting the mixture

The whole process is well shown in the video. Pay attention to the technique of throwing the mortar onto the wall.

Plastering walls on beacons

Finishing putty process

The technology for finishing with finishing putty material is similar to working with a starting solution. After the starting layer has completely dried, apply the finishing layer in the same way: using a trowel, apply the mortar to the wall and rub it in. The only difference is that the coating thickness is minimal, and rubbing must be very thorough, since this process is followed by application decorative covering. You can use several methods of grouting putty: in a circle and in a running manner.

When finishing, it is important not to interrupt the process of processing the wall. Try to calculate the time for finishing entire sections of the facade.

Methods for grouting putty

As you can see, façade putty can be applied with your own hands; all you need is a little patience. By preparing walls for decorative finishing yourself, you significantly save money, which you can spend on higher quality material.

More than half of all residential and public buildings under construction are finished on the facade using the so-called “wet” method using putty and plaster mixtures. They must have certain characteristics in order to serve for a long time without loss of appearance and performance properties.
In this article we will talk about what facade putty should be like for exterior work, how to choose and apply it.

In specialized departments of construction hypermarkets, one’s eyes run wide from the abundance of all kinds of packages with putty. Which of them can be used for finishing facades? What exactly is putty, and what is the purpose of its use?

Purpose of facade putty and requirements for properties

Any putty in its finished form is a paste for eliminating minor surface defects: roughness, cracks, potholes, as well as for leveling it before finishing.
Putty for facade work is divided into two main types:

Starter – with a coarse-grained structure, used for preliminary surface preparation. It has increased strength, adhesiveness, and is well suited for correcting unevenness. brickwork, concrete slabs, foam blocks and others wall materials, since it can be applied in a layer of up to 20 mm.

Finishing – with a finely dispersed structure, applied to a surface previously leveled with plaster or starting putty to create a perfectly even base for decorative finishing. The instructions for such mixtures usually do not recommend applying them in a layer of more than 3-4 mm.

For reference. Also on sale you can find universal compositions suitable for any of the listed types of work and having combined properties. But they are more often used for interior decoration.

Mixtures for finishing facades differ little in appearance and method of application from putties for interior work. But the requirements for their properties are higher.
They must have:

Moisture resistance, since they will have to constantly withstand air humidity and precipitation;
Frost resistance - withstand many cycles of freezing and thawing without changing strength;
Elasticity, the ability to adapt to constantly changing temperatures;
Vapor permeable so that the walls of the house can “breathe”.

Pay attention! Finishing façade putty can be used indoors, especially with high humidity. But mixtures for interior work are never used for finishing facades.

Types of putties for exterior use

For finishing external walls, mixtures based on cement or polymer binders are used. In turn, polymer compositions are divided into acrylic and latex.

Each of these types has its own characteristics, disadvantages and positive properties.

Type of putty	Advantages	Flaws
Cement facade putty	Resistance to moistureHigh frost resistanceDurable, low maintenance Low price	During the drying process they shrink significantlyHigh probability of cracks
Facade acrylic putty	Ease of application Elasticity, no shrinkage Moisture resistance Strength	Small permissible layer thickness: for leveling significant defects you have to make several approaches
Latex based putty	Available in ready-to-use form, does not require kneading. Plasticity. Durability. No shrinkage or cracking.	High cost

What to look for when choosing

In addition to resistance to mechanical and atmospheric influences, when choosing a material, its other characteristics that affect appearance finished surface and ease of working with it.
Basic:

Can be mixed with pigments or tinting compounds to create a blend a certain color. This will allow you to either avoid painting altogether, or apply just one layer of paint, and any chips or other mechanical damage to the surface will not be so noticeable.

Consumption of façade putty per 1m2. It depends on the thickness of the layer, as well as on the fraction of the filler. The smaller it is, the more thin layer will happen when applied. As a rule, large grains of quartz sand are added to the starting compositions, and in the finishing compositions either ground sand or marble dust is used as a filler;

Please note. Mineral chips up to 3.5-4 mm in size are specially introduced into the decorative finishing putty of the bark beetle type. When treating a putty surface with a float, these granules leave marks on it similar to the marks left on wood by bugs of the same name.

Compatibility with paint and varnish compositions that are planned to be used for decorative wall finishing;
The period of setting and hardening of the working mixture;
Plasticity, ease of application.

How to putty facades correctly

Like plaster, façade putty can be applied mechanically using a special unit that supplies the mixture under high pressure. But to do this, it needs to be given a strictly defined consistency; moreover, the hardware method does not guarantee the uniformity of the layer, its equal thickness over the entire plane.
Therefore, it is preferable to apply the composition yourself using a conventional tool - a spatula or grater.
Regardless of the chosen method, the base is prepared before finishing: cleaned of oil stains, dust and dirt, primed with solutions that provide better adhesion of materials and protect the walls from the appearance and proliferation of fungal mold.
Before starting work, simply mix the finished putty, and dilute the dry mixture with water according to the manufacturer’s instructions. It is better to do this in small portions, since the plasticity of the solution decreases over time: the setting time, depending on the composition, varies from 40 minutes to 2-3 hours.
If there are large defects on the surface, first eliminate them by filling all the cracks, joints, cracks and potholes with putty. A continuous layer is applied after the patches have dried.

If it is necessary to apply several layers, each of them is dried and primed again. To achieve perfect smoothness, the finished surface can be sanded.

Advice. Do not putty facades in high air humidity or in extreme heat, when the base is excessively heated by the sun's rays - this will reduce the quality of the finish.

Conclusion

You have probably paid attention more than once to houses decorated decorative putty and painted in a variety of colors. Each of them looks unique, which is what motivates many homeowners to choose this type of finish.
After watching the video in this article, you will once again be convinced of its advantages, and also learn additional information both about the material itself and about the technology of its use.

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 most even surface of a wall 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. It has higher strength indicators and, if necessary, a wide range of colors. 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 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-mentioned preparatory work has been carried out, 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

Facade putties are building mixtures, specially designed for creating optimally smooth surfaces and subsequent application of the final decorative finishing layer. The terms putty and putty combine one concept and are of German origin, therefore in different sources Both designations may appear. The task of high-quality putty is not only to level the surface, but also to maximize the protection of external walls from negative influences external factors.

Fine-dispersed facade finishing materials, depending on their purpose, can be represented by compositions of different size fractions and consistencies:

starting putty, better known as a base or leveling mixture;
the finishing version of a fine-grained putty with a relatively liquid consistency;
a decorative version of putty that allows you to create textured decorative elements;
wood putty used to level and protect wooden surfaces.

Depending on the intensity of exposure to external factors, not only the compositions, but also the technical characteristics of facade putty mixtures can vary. A high-quality putty must be vapor-permeable, moisture-resistant, frost-resistant and sufficiently elastic, which will allow the work to be completed by applying paint, decorative tiles, enamels, mosaics or other finishing materials.

The base and finishing mixture can be waterproof, frost-resistant and heat-resistant:

mixtures with water-repellent qualities minimize the risk of condensation appearing on the surface, which can occur under the influence of rain and evaporation. This putty is distinguished by its simple and quick application, uniform distribution, and compatibility with other types of finishing materials;
frost-resistant mixtures are used when sealing cracks or chips, and increase the resistance of the surface to low-temperature conditions;
heat-resistant compounds combine excellent adhesive properties and have proven themselves when treating surfaces exposed to high temperatures.

Classification by composition

Each putty mixture is characterized strictly established technology produced with a composition, the main component of which allows us to distinguish several varieties that have certain advantages and disadvantages.

Application	Advantages	Flaws
Concrete surfaces with deep cracks. Starting, universal and finishing versions are available, differing in additives.	Resistance to temperature changes, affordable price, ease of work.	Shrinkage occurs and cracking of the layer may occur.
The liquid version levels and decorates the surface. Apply with a thickness of 0.1-0.3 cm onto a previously properly prepared and primed surface.	Good moisture-resistant material with a high level of strength and elasticity.	Not suitable for quick fix deep cracks, grinding requires the use of a respirator.
The paste-like composition has improved moisture resistance and good frost resistance.	Ease of use, high level plasticity and good protective qualities, durability.	Not very affordable price.
Mineral option facade mixture based on liquid glass, produced in a form ready for use. Suitable for working on surfaces consisting of shell rock and cellular concrete.	High vapor permeability, serves as protection against moisture and dust, and has neutral electrostatic characteristics.	A minimal violation of the application technology can cause cracks to appear.
A high level of composition density may affect the uniformity of the applied layer, so certain skills in finishing work are required.	A budget option with high protective properties.	Significant mass and high density, inconvenient application on vertical surfaces.
The presence of polystyrene in the composition indicates frost resistance, and latex additives improve water-repellent properties. The mixture can be presented in powder and liquid versions.	Durable and flexible material with at an affordable price and excellent technical characteristics.	There are practically no downsides when using high-quality material from official manufacturers.
Elastic material with high vapor transmission and strength. Apply in a thin and uniform layer.	Plastic and vapor-permeable composition in a variety of colors.	The cost is too high.

Making your own putty

If there is a need to save cash When purchasing factory mixtures, it makes sense to prepare the putty yourself:

for leveling concrete, relatively smooth surfaces, it is recommended to prepare a gypsum-chalk mixture by mixing three parts chalk and part gypsum. With uniform mixing, the bulk ingredients should be gradually poured into a 5% solution based on wood glue. Homemade solution, mixed until smooth, hardens quickly and should be used immediately after preparation;

for leveling wooden facade It is advisable to use an oil mixture, in the production of which a couple of kilograms of drying oil and four kilograms of chalk are mixed, with the addition of a quarter kilogram of drier. The mixture brought to a boil must be cooled to room temperature.

It should be remembered that the consumption of self-prepared putty will be higher than when applying ready-made factory-produced mixtures.

Preparation of working tools

To carry out puttying work, you will need to purchase some tools to make application easier and get the most even, smooth surface:

a fairly wide brush with soft bristles or a roller, with which the façade surface is primed;

a construction mixer or electric drill with an attachment for high-quality mixing of the putty mixture;

Several spatulas of different sizes allow you to process large areas of the facade, as well as corners or hard-to-reach areas.

Construction mixer price

If paint is supposed to be used as the final finishing of the facade, then the surface must be absolutely flat and smooth, so a well-dried layer of putty will need to be rubbed with a special fine-grained mesh.

Surface preparation

Regardless of the type, the putty must be applied to an absolutely clean, dry and pre-primed surface. It is best to use primer options for putty, which will avoid plastering the surface. Universal primers can be used on any surface, but many experts consider such materials to be ineffective, so they prefer to use special compounds:

Step-by-step instructions for preliminary preparation facade surface for applying the starting putty layer.

Step 1. We remove all external façade decorative elements and antennas that may interfere with the priming process.

Step 2. We fix all loosely fitting elements to the façade surface or remove them completely.

Step 3. We clean the outer surface of dust accumulations with a wet or dry brush with medium-hard bristles.

Step 4. Delete heavy pollution and layers of fatty deposits on the surface with a damp cloth. Too much dirt and paint residues can be removed with solvents, after which the surface is washed clean water.

Step 5. Using a construction roller, carefully apply the prepared primer solution in a thin but uniform layer.

Depending on the composition and weather conditions, the drying process of the primer can take from four hours to a day or more.

Starting layer application technology

Starting mixtures are coarser and coarser. They are used for rough finishing of facades and have good adhesion to concrete, lime, brick and other substrates. Allows you to fill seams, deep cracks and other major defects.

Depending on the initial state of the facade, the working solution can be applied in a layer of several millimeters or centimeters. It is recommended to apply the starting solution thinly, but in several tiers. In this case, it is possible to obtain a higher quality finish.

Step 1. We dilute cement and gypsum putty compositions with clean water in the proportion recommended by the manufacturer. Polymer compositions are already ready for use and just need to be mixed before application.

Step 2. We take a small amount of working solution onto a construction spatula, and then apply it to the surface with a sweeping and fairly wide movement. During the application process, the spatula must be pressed fairly tightly to the surface at a stable angle of inclination.

Step 3. We immediately smear all sagging and unevenness using an empty spatula, and carefully remove excess mixture.

Step 4. After the solution has hardened, we perform thorough grinding, which allows us to get rid of minor defects and makes the surface even and as smooth as possible.

Facades with strong unevenness need to be leveled in several steps.

Quick-hardening compounds self-made or solutions diluted on the basis of dry ready-made mixtures cannot be stored. They are used as quickly as possible.

Features of finishing putty

The composition of the finishing putty mixtures is represented by fine-grained fractions, due to which the processed structure acquires a smooth and durable structure. Coarse-grained putties based on quartz sand or marble chips can also be used, designed to create a relief and highly decorative texture of the facade.

IN recent years The most popular way of decorating the facade of buildings is the option in which they use putty, subsequently pigmented with high-quality coloring compounds. Quite often this method is combined with facing work using natural or artificial materials.

Facade putty can be applied not only manually, but also mechanically, using special equipment. Disadvantage mechanical application is the lack of the most even application.

Main manufacturers

Putties on the domestic construction market can be presented both foreign and Russian manufacturers. Of particular interest to consumers are products of medium price category with high product characteristics.

German cement-based Knauf exterior putties are characterized by high levels of frost resistance and moisture resistance, so they will be the best option for finishing the exterior walls of newly constructed buildings and restoring old façade surfaces.

Finnish acrylic-based putty compositions "Vetonit" are ideal for working with any concrete or wooden bases subject to high humidity levels.

Domestic mixtures “Ceresit”, “Starateli” and “Bolars” compare favorably not only with their affordable price, but also good quality, and also allow you to obtain a durable coating.

Prices for popular types of putty

the surface of the facade must be prepared in advance, cleaned with a brush with metal bristles and thoroughly primed;
moisture-resistant, frost-resistant and relief putty mixtures can be applied to the facade surface only at positive temperatures;
at negative temperatures winter putty such as “Rusean”, “Kreps” and “VGT” should be used;
puttying technology may vary depending on the type of material, but the simplest and most affordable way is to apply along beacons, which will allow you to obtain a layer of optimal thickness;
under each putty layer, a deep-impact primer solution must be applied, which helps to increase adhesion between the base and the applied composition;
putty mixture for painting the facade should be white, since gray putties can negatively affect the decorative properties of the finish.

It should be noted that in the instructions, all responsible manufacturers always indicate not only the composition of the mixture, but also certain nuances of working with the material. Before purchasing, you must make sure that there is a quality certificate for the products being sold.
