The floor requires special strength and rigidity. A thick layer of concrete shrinks and cracks form on the surface. The coating is laid on flat surfaces. Concrete floor putty will help make the base high-quality and durable. Depending on the conditions and coating material, various types are used.

Division of putty for concrete by types and components

On the first floor of the house that my friend was building, the floor was planned to be laid with laminate, tiles, parquet and self-leveling. In some rooms a warm floor system was installed. All these coatings required not only a strong, but also a level base.

Floor putty

Concrete was poured during the construction of the basement and the erection of walls. The thick layer of hard material has shrunk. There were cracks along it in places. To prepare the entire level, we need a variety of concrete floor putty. I started telling Vadik about the materials that we might need and their features. I started with the purpose of the putty:

• starting for sealing the main defects;
• finishing finally levels the surface and creates a film.

Now construction stores offer big choice materials based on:

• cement;
• gypsum;
• epoxy resin;
• polymers.

Using PVA glue or acrylic varnish, you can create your own putty. This work is difficult. Time and quality were more important to us than such savings.

How to choose the optimal composition for the floor

The base in all rooms was the same, differed flooring and microclimate. Based on my stories, Vadik compiled a table to make it easier to navigate when choosing.

Type of putty	Main characteristics	Flaws	Drying time
plaster	flexible, easy to level without sanding	hygroscopic, wearable, destroyed by impacts	1.5 - 2 hours
two-component epoxy	fills voids and cracks, used to seal large defects and cracks, durable, wear-resistant, chemically neutral	difficulty of preparation, cost, fragility	30 minutes
polymer	low specific gravity, glossy surface	price	40 minutes
cement	resistant to moisture, temperature changes, high strength and hardness, wear-resistant	shrinks, cracks, requires lining	12 hours
waterproofing	water resistant, plastic	wears out quickly, dear	can be covered until hardened

A poured floor was planned for the kitchen. Temperature changes, humidity and large cracks spoke in favor of an epoxy two-component putty. Gypsum mixtures regulate indoor humidity. But they cannot be used in rooms with temperature changes. They are destroyed when dew forms.

So we analyzed all the rooms and decided which putty would fit where.

Waterproof materials for bathrooms and swimming pools

Wet areas require materials that will not absorb water and deteriorate. This is a putty based on cement, epoxy resin and special waterproofing.

Epoxy fills deep cracks well, voluminous voids and the screed turns out smooth with a hard film. Preparation of a two-component solution requires strict adherence to proportions. It hardens quickly, after 30 minutes you can’t fix it. It suited us under the screed floor in the kitchen.

It was planned to lay tiles on the concrete floor in the bathroom and toilets. In the hallway, a heated floor system was installed under the ceramic flooring. The cement putty met its characteristics.

Expensive waterproofing putty was used in the pool. Additional components are selected in such a way that they bind the cement, and it does not absorb water at all, being in it for years. It is important that the composition can withstand alternating moisture and dry conditions without compromising strength.

We use environmentally friendly polymer mixtures in living rooms

In the living rooms, we decided to level the floor with polymer putty – acrylic. Warm plaster is more suitable because it does not deteriorate due to temperature. The laminate was chosen without a wax coating, which melts when heated.

PVA glue diluted with water was used as a primer for the concrete floor in dry rooms. For wet rooms we purchased acrylic varnish. These substances:

• penetrate deeply into the pores of the concrete floor and close them;
• increase adhesion to putty.

Before starting work, the floor was cleaned and vacuumed. The first layer of putty was poured a day after treatment with the primer, allowing it to dry completely. The solution was made liquid so that it flowed into all the cracks. The maximum layer thickness is 3 cm. Where more was required, repeat after 24 hours.

After complete drying, the friend primed the floor himself and applied a thin layer of finishing putty of the same brand. Vadik already had experience working with ceilings and walls, so smoothing with a large comb spatula was not difficult.

Advice! Before pouring the floor, place timber in all openings to prevent the mixture from spreading.

Plaster breathes best of all materials

The disadvantage of gypsum mixtures is hygroscopicity and low strength. They perform well in dry rooms, absorbing excess moisture and releasing it when the air becomes dry. The surface of the gypsum putty is smooth. Otherwise, it can be sanded with a machine. The underfloor heating system maintains a constant temperature, and the plaster feels great. Heating does not affect its quality.

The floor covering protects the putty from abrasion and impact. The plaster sets in 15 - 20 minutes, and then dries for about a day. You need to apply it quickly and give it time to settle. The screed will be smooth and without cracks.

Cement putties for industrial premises and a budget option for home

How to cover a concrete floor? Concrete bases have high strength and wear resistance. However, this type of material is prone to dust formation and mechanical damage. To eliminate the possibility of rapid wear of the coating, special liquid compositions are used that protect concrete from moisture, fungal development, chemical reagents and mechanical damage. In this article we will look at the main types of impregnations and paint and varnish products, which are used for treating concrete surfaces.

What materials can be used to coat concrete?

The concrete base is a multilayer structure that has good technical characteristics and “zero” decorative effect. To make it suitable for use, additional surface treatment is required, which would eliminate such drawbacks of the floor as the tendency to generate dust and absorb moisture. What materials are used to improve the technical and decorative properties of the floor?

• polymer impregnation;
• paints;
• putty;
• liquid glass;
• sealant.

The liquid composition, which is applied to the concrete surface, significantly reduces the porosity of the structure. This affects the following gender indicators:

• water absorption level;
• degree of sound insulation;
• susceptibility to chemical and mechanical damage;
• tendency to develop microorganisms (mold, fungus).

Additional protection significantly extends the life of the concrete floor. To understand which type paint and varnish materials preferable to use, consider the above-mentioned means in more detail.

Materials for painting concrete

How can a concrete surface be treated to reduce dust formation? The easiest way to protect the base from moisture, fungus and dust formation is painting. The paint and varnish composition forms a protective water-repellent film on the floor surface, which, if necessary, absorbs all mechanical shocks.

What paints are used to treat concrete surfaces?

• Epoxy.
• The durable and abrasion-resistant composition is used for painting concrete surfaces both indoors and outdoors. The paint has good waterproofing properties, is resistant to chemicals and has good adhesion to concrete surfaces; Acrylic. A liquid composition based on acrylic resins and plasticizers prevents chemical and mechanical damage to the base. Protects the floor from moisture,
• high temperature

and UV rays;

Polyurethane.

Polyurethane coating is a two-component solution that can be used for finishing concrete indoors and outdoors. The polyurethane composition prevents the penetration of moisture into the concrete structure, which prevents its premature destruction. Epoxy and acrylic varnish for concrete floors can be applied to the surface even at low temperatures. In particular, epoxy paint does not peel off even when painting fresh concrete. Impregnation Dust-removing impregnation is a liquid composition that is used to strengthen concrete pavements. The material is a cheap alternative finishing floors

, which cannot be used in fairly harsh microclimatic conditions. Impregnation can be presented

• various types solutions that increase the strength, moisture resistance and abrasion resistance of the floor. What impregnation is used to treat concrete surfaces? Organic based. IN in this case
• impregnation can be made on the basis of epoxy resins and binders, which form on the surface of the base protective film

. Treating concrete with organic materials can improve the water-repellent properties of the coating, as well as minimize dust formation on its surface;

• Synthetic based.
• Impregnation based on inorganic compounds creates glass-forming oxides on the concrete surface, which affect the hygroscopicity of the base and its mechanical strength.
• A liquid anti-dust agent not only improves the decorative properties of the floor, but also helps protect it from the occurrence of:
• thermal expansion;
• mold and mildew.

What is "Protexil"?

“Protexil” is a liquid composition made on an organic basis, which is used to strengthen and remove dust from concrete surfaces. The water-repellent properties of the coating are provided by the polymer inorganic compound and plasticizers present in the material. For what purposes is Protexil used?

• Strengthening low-grade concrete pavements;
• Increased resistance to mechanical damage;
• Protecting the base from moisture;
• Increased adhesion to subsequent types of coatings.

"Protexil" allows you to significantly expand the scope of application of concrete coatings. If they themselves do not have outstanding technical parameters, special impregnation can significantly improve their physical and mechanical characteristics. “Protexil” is a liquid composition that provides a sufficient level of protection of dust-forming surfaces from mechanical damage.

You can use Protexil not only in the building, but also on the street. Processed special means Concrete coatings are safely used in construction:

• warehouses and bases;
• meat processing plants and chemical production;
• car services and parking lots;
• workshops and utility rooms.

It should be noted that “Protexil” is strictly not recommended to be applied to cement laitance. To ensure good adhesion of the base to concrete, Protexil is applied only to a porous and dry concrete surface.

Liquid glass

Is it possible to treat the base with liquid glass? The composition itself is a mixture of an aqueous solution, quartz sand and sodium silicate. Liquid glass have long been used in the construction industry due to its excellent qualities, which include:

• Good water-repellent properties (water absorption coefficient no more than 2%);
• Inability to accumulate static charges;
• Increasing the density of porous surfaces;
• Protection of the base from the effects of alkalis and acids.

Liquid glass is also used to process seams if necessary. A high-quality composition with water-repellent properties protects all vulnerable areas of the structure, which affects its service life. At the same time, concrete coatings can be coated not with liquid glass, but with paints based on it:

• Dispersed silicate. The combined composition additionally contains water repellents and an inorganic dispersion. This type of glass is often used to seal seams on mineral substrates, as well as to process wood and metal coatings;
• Silicate.

Liquid glass does not contain any organic compounds and can be safely used for painting mineral substrates. Silicate coatings are very resistant to acids and alkalis, so they can be used not only inside buildings, but also outside.

Sealing joints on concrete bases

The protection of mineral coatings consists not only of additional surface treatment with reinforcing compounds, but also of sealing the seams. Special mixtures help prevent moisture from entering vulnerable areas of the structure, which has a beneficial effect on the service life of the entire floor. What is a sealant and why is it needed? Sealant is a protective liquid composition with water-repellent properties, which is used to seal seams on mineral substrates. It may contain various components that affect specifications

mixtures. The greatest demand is for rubber and polyurethane sealants, the water absorption coefficient of which does not reach 1.5%.

• For what purposes are polyurethane and rubber sealants used?
• Sealing microcracks and seams on mineral coatings;
• Installation of expansion joints in the coating;

Sealing joints formed as a result of vibrations. Rubber seam coating is an indispensable assistant

when repairing concrete floors outdoors. The hardened sealant practically does not allow moisture to pass through and prevents the appearance of fungus at the joints.

Do you need putty? Putty for concrete floors – the best way protecting the coating from further destruction. Monolithic design has good strength characteristics and is little susceptible to negative impact

environment (temperature expansion, exposure to moisture). But if any cracks or chips appear on the surface, the technical parameters of the base deteriorate sharply.

The type of floor putty depends on the type of coating surface and the desired result at the end of the work. Often the floor is puttied before laying laminate or linoleum.

Concrete floor diagram

1. There are three types of putty:
2. Base, which is applied as the first layer to level out the most basic irregularities.
3. Finishing, which is applied in a finally even thin layer.

Universal, which is suitable instead of finishing and basic. In order to do right choice

for the floor, first of all it is necessary to determine the surface of this coating.

Scheme of modern finishing materials.

Its peculiarity is that it is a little thinner, due to which, under the influence of gravity, it can be more evenly distributed over the surface. Putty for concrete floors is sold in any construction stores at a price of approximately 200 rubles per package weighing 5 kg.

Putty for polystyrene foam must be applied in a special way. It is applied in 2 layers, the thickness of each of which should not be more than 2 mm. Putty for expanded polystyrene is applied no earlier than one day after the installation of expanded polystyrene is completed.

Wood putty requires a special approach. When puttingtying wooden coverings, follow the instructions on the packaging.

Putty for leveling the floor is sold by dealer companies or in hardware stores.

Often, polyester is used for concrete floors, the features of which are elasticity, strength and good adhesion. Polyester putty has no shrinkage. However, when working with it it is not recommended to take large layer, since the most the best option is to apply 2 thin layers.

Polyurethane putty is popular among both beginners and professional repair specialists. It is quite easy to use and has a number of various advantages, such as resistance to water, acids, gasoline, alkalis, organic and synthetic solutions. Polyurethane is ideal for concrete, wood, metal and mineral surfaces, is most often used indoors, and is environmentally friendly to the human body.

Scheme of cork floors on a concrete base.

The main purpose is to level the surface before applying coating materials. It is better to putty any type of surface before painting or wallpapering.

Putty for concrete floors is used as a universal material for leveling it.

The domestic market of construction and finishing materials mainly offers putty in the form of a dry mixture. In this regard, first of all you need to mix the putty, then prepare the surface. Before filling, the coating is cleaned of grease and dirt and, if necessary, treated with a primer. The instructions on the package will help you properly dilute the putty from the dry mixture. One point should be noted here: putty for a concrete floor is carried out due to gravity, so it should be slightly thinner than a regular solution for ceilings or walls (diluted with water in a ratio of 1:5).

For waterproof surfaces, the putty is diluted a little thicker (1:3). Next, you should lay the putty in a thin, even layer on the surface. The use of a thick layer is unacceptable, as this will promote the formation of cracks. After the putty has hardened, you need to remove the excess with a spatula and level it with sandpaper. For more information on how to use a particular type of putty, it is best to read the instructions on the package. For example, putty for polystyrene foam requires preliminary degreasing of the surface and is laid in 2 layers.

Scheme of a standard floor screed.

The dry mixture must be diluted in the amount required, because after the stated time has elapsed (usually 4 hours), it will become unsuitable for use.

It is important to choose a putty according to the requirements for room humidity and drying time. There are types that can only be used indoors with low level humidity and at a certain temperature. Before further work, you must wait until the putty on the surface is completely dry. On average, complete drying time is 24 hours.

Putting the floor requires some preparation and takes a lot of time, so it is often easier to turn to specialists.

Waterproofing polyurethane material

Waterproofing is characterized by increased resistance to the effects of organic and mineral environments, mechanical strength against tearing and compression.

Waterproofing putty is used both in combination with other materials and as an independent coating.

Application

Scheme of concrete hardeners.

• This type is used for waterproofing concrete floors, for sealing cracks (including small ones) and for creating a waterproofing protective layer under a self-leveling floor system. The putty can be applied to a damp base and to fresh concrete;
• putty is used for waterproofing water tanks and swimming pools, under cement screed and tiles, treatment facilities and sanitary premises, as well as for external waterproofing of foundations;
• this waterproofing coating is environmentally friendly and can be used in explosion and fire hazardous areas;
• consumption depends on the thickness of the layer and is 1.5-4.0 kg/m2;
• after completion of work, the tool is cleaned with water;
• The composition includes a 3-component urethane compound, consisting of a semi-finished product (urethane film former with targeted additives and an aqueous dispersion), a dry mixture and a hardener.

Storage

• the semi-finished product is stored at a temperature of at least +5°C;
• The shelf life of hydrospar in original packaging is 12 months from the date of manufacture.

Another way

Scheme of floor insulation with polystyrene foam.

There is another option to putty a concrete floor. To begin with, it is necessary to repair potholes and cracks on its surface and prime it. You need to start by cleaning them thoroughly so that the putty adheres well. In order for it to better adhere to concrete, it is necessary to first coat the cracks with PVA glue mixed with water in a ratio of 1:5.

If the floor in the room is wavy, then after eliminating the defects, it must be filled with a leveling solution, having previously been cleaned of dirt and dust.

After the floors are puttied, you need to prepare a leveling solution. The cement mixture is combined with water. Stir until it becomes liquid sour cream, then lay it on a damp floor surface in a layer of 3 mm and smooth it with a grater. After some time, the solution will completely level itself and traces of smoothing will disappear. After 2-3 hours of drying, it will be possible to walk on this floor, and after 8-9 hours it will be possible to lay porcelain tiles.

If the floor begins to become covered with moisture, it will be necessary to waterproof it. To determine moisture penetration from below (through concrete), it is recommended to place it upside down on the floor. glass jar, while sealing the joints. After 2 days you need to check it: if droplets of water appear inside the jar, this means that moisture is coming from below. If droplets of moisture have formed on the outside of the jar, then it is condensation inside the room.

In order to prevent moisture from entering through the concrete floor, it must be covered with 2-3 layers of bitumen mastic. It is necessary to first remove the baseboards and treat the walls behind them with mastic.

There is a need to cover up all the sinks and a few small holes. I know that there are finishing coatings, but I don’t see the point in additionally pouring at least 2mm of solution (according to my modest experience and the experience of other forum members). What options are there? I’ve only seen ready-made putties for parquet, and they’re not cheap)? The first thing that came to mind was to use parquet glue. But not all of them are diluted, and the putty must be liquid. Second, thin out the self-leveling mixture not with water, but with primer + PVA. Yesterday I even tried it on a small area, it seemed to stick well. Who has experience?

I tried Vetonite 3000, puttyed it with a wide 60 cm spatula, primed ST17 with this, the flight is normal - the fourth year, nothing peeled off...

Just dilute it with water until liquid and that’s it? How thick is the layer? For sealing shells it is less than 1mm.

Just yesterday we measured the differences on a rough screed and it turned out that in the kitchen the level dropped by 5-10 mm. It’s not a good idea to lay the laminate on such a kagbe, so we took 5 bags of finishing self-leveling material. It took 2 bags for the kitchen; they decided to putty the rest of the floor with the same mixture - purely for beauty. One layer took half a bag.
They diluted it in the same way as for pouring, poured it onto the floor a little at a time and dispersed it to zero with a spatula. To create a “mirror” one thin layer is not enough; as with puttying, you need 2-3 layers (and sanding if desired). If you want to sand, don’t delay it - every day the “putty” becomes harder.
p.s. pouring - any where a layer “from scratch” is allowed.

You still did it in the standard way, you won’t get a layer less than 1mm. Even if you prime it three times. That's why the question of putty came up. There is a video of how parquet is puttied by continuously applying a thin layer of putty. After this, it is sanded and a smooth surface is obtained. I want to do the same with a concrete floor.

Who were you talking to just now?

From the experience of forum members? I haven’t read anything about concrete floors being puttied....

WATERSTOP, try it. Waterproofing on cement. Why not an option?

“Nalivaika” (self-leveling mixture) also sands perfectly. Tested personally on P3 plitonite, oak parquet is no softer than liqueurs. Of course it’s more complicated, you can’t do without a diamond cup.

I referred to the experience of forum members regarding the minimum thickness of the pourer, they write from zero, but in fact from 2. Read carefully. GLIMS WATERSTOP - I'll try to look for it.
At the moment, a test piece of a well-diluted liqueur with a primer with the addition of PVA seems to have turned out well. I'll try to implement this option this weekend. The only thing I missed was not filtering it through the stocking.

In general, ideally such situations should not exist. Either a screed, or a screed repair, or a floor. If something is different, there will be difficulties, you need to get away from them.

OK thanks.

Ideals are the exception rather than the rule, even for professionals

Two-component putties, if they are liquid, most will do. You can use epoxy varnishes and adhesives, into which you need to add quartz dust or ground sand. My version also worked. In general, thank you everyone.

Colleagues, I decided to ask a question without creating new topic. I have a concrete floor, covered in sinks, and I plan to cover it with ~4mm thick linoleum. I sealed all the sinks with putty (gypsum). But then the thought came: damn, this putty will crumble and gather dust. What to do: prime everything thoroughly so that the putty doesn’t collect dust, or, in the deepest and widest places, dig out cement there too, and then prime it?

Yaroslav,
The problem is not that it will collect dust, but that if you drop something heavy in this place and there will be a dent.
Therefore, in the widest places, replace Nuno with cement.
You need to prime it naturally - it will be easier to remove debris in front of the linoleum.

So, I peeled off this putty and started applying cement. But then it turned out that instead of normal cement, I mistakenly bought decorative white cement with marble chips (also called c 400, if I’m not mistaken)). Will this cement be as strong as without additives?

..I honestly don’t understand what is planned to be laid on this floor?))..if it’s tiles. Why then bother with puttying?.and in general, if you want to putty the floor. I conclude that your floor is smooth, without bumps and pits, only with small sinks... lay tiles or lay laminate and don’t break your head))

Floor putty

To choose the right putty for the floor, you need to determine the surface of the existing coating.

First of all, putty can be basic, that is, used as the first layer to level out the main irregularities, finishing, applied in a thin, even layer, and universal, suitable both instead of the base and instead of the finishing.

Putty for concrete floors is most often self-leveling, which is very convenient and practical. Its peculiarity is that it should be a little thinner, due to which it can be more evenly distributed over the surface under the influence of gravity. Putties for concrete floors can be purchased at any hardware store at a price ranging around 200 rubles per five-kilogram bag.

Putty for polystyrene foam requires some special application. It is applied in two layers, the thickness of each should not exceed 2 mm. Putty for expanded polystyrene is applied no earlier than one day after laying expanded polystyrene.

Floor putty requires a special approach. Therefore, when filling wooden surfaces, use wood putty, following the instructions on the package.

Putty for leveling the floor can be purchased from dealers of companies that manufacture it, in construction stores, or directly from the manufacturer.

Most often, polyester putty is used for flooring. Its features are strength, elasticity and good adhesion. Polyester putty does not shrink, however, as in all cases, when working with it, you should not take a large layer. The number of thin layers should not exceed two.

Polyurethane is no less popular both among repair specialists and among beginners in this field. It is quite easy to use. It has a number of advantages, such as water resistance, resistance to alkalis, acids, gasoline, synthetic and organic solutions. The putty is suitable for metal, concrete, wood and mineral surfaces, is used mainly indoors, and is environmentally friendly for humans.

How to use putty

The purpose of putty is to level the surface before using coating materials for a more even effect or to give relief. It is better to putty any surface before using paints or thin ones.

Floor putty is used as a universal material for leveling the floor. The floor is puttyed using a spatula.

Basically, the domestic finishing building materials market offers putty in the form of dry mixtures. Therefore, first of all, it is necessary to prepare the surface and putty for application. Before filling, the surface is cleaned of dirt and grease and, if necessary, treated with a primer. You can learn how to properly dilute putty from a dry mixture from the instructions on the package. One point should be noted here: floor putty is carried out mainly due to the force of gravity, that is, it should be somewhat thinner than ordinary mortar for walls or ceilings. For those that do not absorb water, the putty is diluted a little thicker. Then you should lay a thin layer of putty on the surface (the use of thick layers is not acceptable, as cracks will form). After the putty has hardened, you can level it using sandpaper or sanding attachments, and remove excess with a spatula. It is best to read the instructions on the package for details on how to use each type of putty. For example, putty on polystyrene foam requires additional preparation to degrease the surface and is applied in two layers.

The putty must be diluted in the required quantity, because after the stated time (for most putties this is 4 hours, you can check on the packaging) it will be unsuitable for use.

It is important to choose a putty according to the requirements for room humidity and drying time. Some putties can only be used in areas with low humidity levels and only at certain temperatures. It is necessary to allow the putty on the surface to dry completely before further work. On average, drying time is a day. It can be specified on the packaging.

Often, floor putty takes a large number of time and requires some preparation, so it may be more convenient to turn to specialists.

print version

Creating a flat, durable floor - important stage carrying out repair work. To eliminate unevenness on concrete foundations, various building mixtures and compositions, including putties, are used.

The concrete floor itself has high strength, but if there are minor defects (chips, cracks and crevices) and poorly puttied slab joints, it can be subject to destruction, which will entail repairs and significant financial costs, especially when it comes to public buildings.

Additional strengthening of the concrete base will also be required in cases where cheap materials were used in construction. Treated floors have a number of advantages:

• high wear resistance;
• resistance to erosion;
• resistance to abrasion and mechanical damage, exposure to chemicals and moisture (including leaks);
• longer operating period.

Putty mixtures thoroughly and reliably level the floor, ensuring easier further installation of building and decorative materials.

Putty mixtures for concrete

Putty materials can be base and finishing. But there are also intermediate universal options suitable for all operations; they are much more economical and have low consumption.

Based on their component composition, mixtures of the following types are distinguished:

• cement;
• gypsum;
• limestone;
• oil;
• adhesive;
• varnish;
• polymer or acrylic.

Basic putty PROMOTERS 5 kg

Often manufacturers additionally enrich the putty with polyester or polyurethane additives. Such materials have minimal shrinkage and high waterproofing properties.

According to the form of release, the mixtures are:

• dry, diluted with water in the specified proportions;
• paste - ready-to-use compositions.

Depending on the application method, the putty can have a liquid or thick consistency. The first type is typical for self-leveling compounds used for treating concrete floors. Such mixtures, under their own weight, are effortlessly distributed evenly over the entire surface, characterizing the continuous puttying technique.

Gypsum mixtures

Gypsum-based putty mixtures are the least popular option for leveling the surface of concrete floors. The advantages of this material include:

• no shrinkage;
• low cost.

The gypsum composition creates a perfectly flat surface from the first layer, dries quickly and can be colored with any color (as a more budget option you can use artistic gouache), however it has one significant drawback - the material is not suitable for rooms with high humidity.

Cement putties

Cement-based putty mixtures successfully combine reasonable prices and stable high quality coatings and moisture-resistant properties. But the material also has a number of disadvantages, including:

• noticeable shrinkage after complete drying;
• the difficulty of leveling the mixture on the surface and the need for certain skills in working with cement compositions.

Special component mixtures make the finished coating resistant to temperature changes and allow the use of such putties in rooms with extremely low and high humidity, since strength and durability are maintained throughout the entire service life.

Acrylic mixtures

One of the most convenient forms - it hardens quickly and creates a smooth surface. The multi-component system is not subject to shrinkage and is not afraid of water.

In addition to water, the composition of polymer putty for concrete floors includes sand, marble chips, cement, and synthetic additives. This putty is plastic, has good waterproofing properties and adhesion to the surface being treated, is waterproof, and elastic, which makes it excellent material for preparing the surface for self-leveling and heated floors. But its use is advisable on surfaces with a small number of deep cracks and gouges.

Epoxy mixtures for concrete floors

If it is necessary to level and strengthen a concrete base with a damaged structure (large cracks, embroidered seams and traces of reinforcement removal), the use of epoxy compounds will be most effective putty mixtures, tightening concrete and increasing its strength and durability.

The advantages of such two-component systems, consisting of a base and a hardener, are:

• high-quality filling of cracks, crevices, joints;
• elimination of voids formed in places where pipes, communications, etc. were replaced;
• strengthening difficult areas and tightening structural damage;
• the ability to create a durable and wear-resistant continuous coating that does not require further processing;
• high adhesive properties;
• minimum percentage of detachment of the dried putty layer from the base;
• resistance to moisture, chemicals, as well as microbes, mold and mildew.

Epoxy mixture is a finishing material ideal for smoothing out all the depressions and unevenness of the floor covering.

Waterproofing putty mixture

A special feature of the mixture with increased moisture-resistant properties is the possibility of using it as an independent coating, which will be beneficial with a limited budget for repair work. The composition of the putty includes urethane components, a dry base mixture, a hardener, targeted additives and dispersion emulsions.

Most often, waterproofing putty is used when carrying out repair work in bathrooms, steam rooms and showers.

The main advantage of the material is that there is no need to wait for the base to completely dry and the ability to work on a wet layer.

Criteria for choosing putty

It is very important to choose the right building mixture, taking into account the properties of the surface being treated and the purpose of the room. It is important to pay attention to the following properties of the putty mixture:

• adhesion indicator - there are special solutions for smooth surfaces;
• type of base (concrete, aerated concrete);
• moisture resistance, since the putty layer must reliably protect the concrete base from moisture;
• vapor permeability (the ability of a material to remove excess moisture).

Type of putty	Purpose	pros	Minuses
Cement	For rooms with high humidity and outdoor use	Moisture-resistant, cost-effective	Significant shrinkage, possibility of cracks appearing over time
Plaster	For rooms with low humidity	Forms a smooth surface, does not shrink, hardens in 2-3 hours, maximum layer 4 mm	Not moisture resistant, the solution thickens in 1.5-2 hours
Polymer	For residential premises and rooms with normal humidity	Lightweight and easy to use, hardens quickly. The coating is smooth and glossy. Ideal for finishing coats	Expensive

Important! Pastes and mixtures for concrete foundations not suitable for aerated concrete and vice versa. Because they contain various component additives suitable for a specific structure. When choosing a mixture, you need to remember that how evenly and smoothly it will lie will depend on its quality. Decoration Materials(parquet, laminate, linoleum or ceramic tiles).

Step 1. Preparing the work surface

The room in which the work will be carried out must be prepared in advance. It is advisable to remove the old floor covering, widen deep cracks and crevices using a drill and clean with a construction vacuum cleaner.

Then seal it cement mortar(cement: sand: water: bitumen = 1: 3: 1: 0.5) and wait until the surface is completely dry. Instead of bitumen, you can use PVA glue.

It is very important to remove all stains from the floor:

• dirt;
• rust;
• fungus;
• mold.

Usually they are easily washed off with warm soapy water, but if necessary, you can use specialized products.

Step 2. Prime the surface

Before priming, the floor should be cleared of debris or swept again. The primer must be selected based on the characteristics of the room, its humidity and purpose.

To apply the composition you will need the following materials:

• roller or brush;
• special pallet.

The primer is applied in two layers, each of which is thoroughly dried. A high-quality composition will seal pores and small cracks, making the next step easier.

Important! If the base is smooth, then it is preferable to use a primer with a quartz filler - it will ensure stronger adhesion of the putty to the concrete due to the rough surface obtained after priming.

Step 3. Preparing the solution

The putty can be purchased ready-made, or you can mix the composition yourself. To do this, you will need a drill with an attachment or a construction mixer, a suitable container and dry mixtures. It is very important to follow the dilution proportions indicated on the packaging.

There is no fundamental difference between the coating obtained from thick and liquid plaster, but there is a difference in applying the composition to the working surface.

Experts advise adding 10-15% more water than the manufacturer recommends. The optimal ratio of dry mixture and water is 1:5, the minimum is 1:3.

Sometimes you can add sifted chalk, crushed sawdust, and PVA glue to the building mixture yourself.

The sawdust must first be soaked for 12-14 hours, and the entire mixture must be stirred twice with a mixer. To putty bathrooms, drying oil is added to the composition - this will make the final coating even more resistant to temperature changes.

Keep in mind that the solution thickens after 3-4 hours and becomes unusable, losing up to 20-25% of its properties, so you should not make a lot of construction mixture at once.

Step 4. Applying material to the surface

The puttying process is quite long and painstaking. The tools you will need are the following:

• spatulas of various lengths;
• Master OK.

For convenience, you can purchase a rubber spatula or a tool with comfortable handles, be sure to take care of the products personal protection and gloves. The putty is applied in 2-3 layers, each no more than 4-5 mm thick. You should not try to eliminate all unevenness with putty - this process is carried out during the execution of the floor screed.

1. Place small portions of the mixture on the floor or pour out part of the mixture, then quickly spread everything over the surface with a spatula. Try not to make the first layer too thick - there is a risk that the coating may crack.
2. If the treatment area is large, you can use a reinforcing mesh with small cells - this will at least double the strength of the coating. It should be lightly pressed into the first layer of putty immediately after its application, without waiting for it to dry.
3. After the first layer has hardened (after about 12-16 hours), re-apply the freshly prepared mixture.

The putty will dry completely after 24 hours. If there were deep cracks, the process may take 2-3 days. It is important to dry without drafts or sudden temperature changes.

Step 5. Elimination of irregularities

After final drying, large irregularities and protruding lumps of unmixed material should be treated with coarse sandpaper P120-150.

With sufficient skills, puttying can be done independently, without resorting to the services of specialists. Concrete floors are quite easy to level, and if all recommendations are followed, the coating will be of high quality and without defects.
