Friends, in this article we will try to shed light on the most common questions that arise in the process of searching for suitable laying glue ceramic tile, ceramic granite and ceramic mosquito. Tell how to choose the desired adhesive mixture, how to correctly calculate its consumption and how to save everything on this.

The more water "takes" the surface, the easier it is to stick to it. Various additives for low-continuous surfaces are added to the glue. They improve adhesion, but increase the cost of adhesives. Tables on the left side are simpler and, therefore, less expensive adhesives, on the right side - more complex adhesives with special properties. The price of such adhesive is higher.

Our company was chosen by these manufacturers of tile centers known in the Lithuanian market. Some of our customers prefer to work with one glue, and the other part with others. Both products are reliable and fully comply with standards. Let's look at some examples of glue selection.

We want to immediately make a reservation that all the calculations below are averaged - for easier and visual perception of the material not by specialists in the field of construction.So, proceed:

According to its properties and composition, tile glue is divided into three main types:

epoxy

dispersive

on the cement based

Heated flooring tile

Heated floor - rather complicated installation. Elastic glue should be used to reduce strength. The more adhesive elastic, the more soften the negative effect. The "sandwich" of electrical floor carpets are thinner, and the arising deformation forces are weaker than in the case of heating pipes. Therefore, for electric floor heating, tile glue can be "weaker" than floor tiled floors.

When choosing glue, it is also necessary to take into account the tile type. If you choose a ceramic or clinker plate for heated floors, glue can be elastic. Ceramic tile, we recommend choosing an extended glue and laying natural stone or granite, such as glue necessary. Glass mosaic or marble must be glued with white glue.

Epoxy glue for tile

The most unclaimed option for ordinary use is done. One square meter Ceramics glued with such glue "will turn out" to us 1,000 - 1,500 rubles, which is commensurate, and sometimes even exceeds the cost of the tile itself!

What is such waste? Epoxy adhesive superpower, waterproof, frost-resistant, does not give a shrinkage and does not crack over time. Ideal for laying in maximum load areas, with high vibration levels: subway, airports, shops, ship premises, recording studios, elevator cabins, columns, stairs.

When assembling glue for heated floors, it is assumed that the tiles are glued to the newly installed concrete floor. The glue offered in the table may be easier if concrete for heated floors has elastic amplifiers. Tables on the left side are easier and, therefore, less expensive tile glue, right - elastic and complex, having special occasions of the property.

Tile glue for terraces and balconies

When laying tiles on a terrace or balcony not all used tiled adhesives. Only highly elastic glue, specified in the table, can counteract the effects of cold and moisture. Glass mosaic and natural marble glued with white glue, which will not change the color of the coating. For large floor tiles there are special tile adhesives.

The selection of epoxy tile glue can be due to both when it is necessary to bind a smooth surface: metal, plastic, wood, plasterboard, preceding tile, facing stone or brick. Designed for both internal and outdoor work. "Prepaid" by mixing several ingredients, which are present in the package in the necessary proportions.

Tile adhesives for the kitchen, home corridor and other rooms

Please note that not all tiles are suitable for outdoor conditions. Adhesives used in residential premises do not fall under special requirements. If you want to attach large-format tiles to the wall, select other adhesives. The glue adds a plurality of additives for low humidity surfaces. The absorption of ceramic tiles is the highest, therefore it is easier to glue and glue tiles: in the table they are on the left side. Do not make mistakes that any simple glue is suitable for gluing ceramic tiles: we make recommendations, and we can take responsibility for glue in the table.

Composition of epoxy glue
Component A - epoxy polyurethane resins, inert fillers and organic additives. It has a paste-like consistency of white. Component B - catalyst on organic basis With the addition of fibers.

Tile Dispersion Glue

Mene is expensive compared with the epoxy basis. The cost of one square meter of the surface, lined with dispersion cool composition, will cost us 600-800 rubles, which is 1.5-2 times more economical, but still significantly "hits the pocket" of the average resident of Russia.

Simple gluing will not be applied to glued stone and clinker tiles - you will need more strength, and if you use two-point glue in the table, you will have a higher stock of reliability. They may be required if tiled water in the selected tile is particularly low: tile manufacturers constantly seek to reduce it to create a more stable plate for the environment.

Natural stone and granite require extremely durable and elastic glue, and glass mosaics and marble should be white. Not only are the tiles differ from the point of view of water absorption - and the foundation on which we tile. In the Glue Table for different types of substrates. If for some reason you installed the foundation with waterproofing, you need to evaluate the glue.

Due to the high elasticity (flexibility) of the solidary mixture, it is primarily used for laying tiles to deforming surfaces, for example on wooden or plastic panelswhich can be fed with time. When cladding drywall, a dry-fiber sheet and gypsum plaster - there is no need for their pre-processing of primer.

Tile glue for wet rooms: bathroom, shower, pools, raw basement

For very difficult grounds, use the most stronger and sticky adhesive glue. When installing bathrooms, especially when landscaping floors or cladding of pools, we are facing more than regular humidity. A similar situation is observed when gluing tiles in wet basements. Simple tiled adhesive here is not suitable. And why should very glued gluing glue be used in wet rooms? To do this, there are several reasons: protect the rooms from moisture, install waterproofing and always exacerbate gluing tiles with a base.

The dispersion glue is sold in the ready-to-use form, quickly collapsing and freezes, some species have a thixotropic property (when laying on the wall, the tile does not slide), resistant to moisture, well suited for painted surfaces and is not recommended for use with concrete bases.

Composition of dispersion glue
Based on synthetic resins, with inert fillers and organic additives.

In cases where waterproofing is not installed, the excessive humidity "saturates" the tiles with water and absorbs less moisture from the glue. In both cases, only sticky glue can improve adhesion. As in all other cases, glue for glass mosaics and marble should be white.

You will find an answer to the question on this page and on your email. Installation of multifunction rooms, the tile is especially paid much attention, because it is one of the most unclosed reconstructed internal finishing materials. You can enjoy the choice of tiles for a long time will depend not only on their quality and skill of workers, but also from the selected tile glue. Knowing signs of value, you will quickly and for sure you can choose the best product for your needs.

An important nuance of glue selection!
The need to apply expensive epoxy and dispersion adhesive mixes Can only determine the construction specialist in the field of construction. These types of adhesive are used, as a rule, in highly specialized situations where cheaper analogs are missing or not enough.

You will need the following categories of glue if glue tiles and large tiles will experience large loads. Elastic properties, important for styling tiles on unstable surfaces, heated floor, or when performing work in the field. T - lower slide. This important feature of the tile on the walls is especially greater or harder.

This is especially true for the gluing tiles of large areas. The actual objects where it works in rigid time limitations. When choosing glue for tile, it is important to pay attention to several key moments. Place of work and conditions. Surface for sticking tiles.

From the above, it can be concluded that if we do not make facing tiles of metro stations, cabins steamers, elevator cabins, glass rooms, pool bowls, and we make ordinary repairs in the usual room (apartment, house, office, shop, restaurant) then with probability 95% of our needs will be able to satisfy the most popular version of tiled glue, namely:

Let's consider some of the most common cases.

Sticky smooth concrete, plaster or plasterboard panel, large temperature differences are expected. This happens, for example, in a garage or boiler room. This is important because there are no emptiness that can accumulate in condensate, the tile can withstand heavy loads. These adhesives are indispensable in cases where we have reason to be unstable - a type of waterproof tree or chipboard cement, one glue tiles on the tile. Pretty popular luxurious interior finish solution - glass or ceramic mosaic are also transparent stone tiles or panel.

Cement-based glue

The standard of the industry, the high popularity of which is due primarily to the low price with very decent characteristics. It is noteworthy that one square meter of tiles, laid out with such a glue mixture will cost us only 70 rubles, which is 10 times cheaper option with dispersion glue, and almost 20 times! - with epoxy.

You may have noticed that walls or outdoor tile Pulling, when adhesion tile glue to the substrate or tiles is not enough, and this is due to improper preparation of the base, gluing technology or violation of one of the most common causes is the incorrect tile glue.

To install multipurpose rooms, the tile is paid to special attention, since it is one of the least renovated materials for finishing the interior. Will you enjoy selected plates for a long time, it will depend not only on their quality and skill workers, but also from glue. Knauf, a German company that built construction materials over 80 years, noticed that more precisely, materials Used by destination, the longer they serve.

Cement-based glue composition
How correctly you guessed from the very name, the basis of such a glue mixture is cement and sand. In order to give this building material additional propertiesPolymer, latex and other additives can be added to the composition depending on the goals pursued.

As you can see, each type of glue is indicated by the letters of a certain category. Knowing the meaning of this markup, you can quickly and accurately choose a product that best matches your needs. The class of elasticity is important for laying tiles on unstable surfaces, outdoor heating or outdoor work.

On the terrace or facade or on unstable bases - especially elastic. This category is important for gluing tiles on the walls, especially large or severe. When choosing a tile glue, it is important to pay attention to several key criteria: the size of the tile, the location and conditions of operation, tiled materials, working deadlines, to the surface on which the tile will be glued.

Cement-based glue is a dry adhesive composition, and has a number of certain advantages over more expensive, specialized analogues:

First of all, this is an affordable price that we wrote in more detail by several paragraphs above.
The widest range among all types of glue, and as a result - versatility. Due to what, in almost any surface, you can choose a suitable series and not overpay for more expensive analogs. The composition of hypoallergenic and harmless materials. So, you can safely use in residential areas, kindergartens, clinics, etc.
Availability - Cement glue can be purchased almost anywhere where they sell construction materials.
Ease of use and low price of a possible error. How to properly prepare glue on a cement basis to work, and how to behave with it during the installation of the tile knows every self-respecting master, which cannot be said about specialized dispersion or epoxy gluethat require special knowledge, skills and work experience with the material.

Among the entire represented range of dry glue mixtures, we would like to highlight the two most universal, inexpensive and popular positions of the Italian brand Litokol (litelicol).

The adhesive surface is equal to a concrete or plaster plate, and there should be no higher temperature differences in the room. In this case, you will be provided by Knauf. Most often they won the most expensive tiles - because they are closer to the female side of the family, and then it is called another to buy glue and putty.

Last, so costs are not too high, bought with the cheapest. According to Jurgis, there must be a hat. The design of the highest level will go to the wind, if the work is performed with insensitive, incorrectly selected materials. Although it would seem that there is nothing easier than choosing tiled glue and putty, you really need to know several important things.

Litokol K17. - glue for ceramic tiles, the main advantages of which are manifested at an affordable price and a wide range of applications. It can be used for both internal and outdoor work. Resistant to mechanical loads, a sharp change of temperature regime, has a high indicator of adhesion and elasticity. Quickly hardened. Environmentally safe.

Depending on which tiles and where they are glued, it is also necessary to choose the elasticity of the glue: simple tile glue will be used in dry ceramic rooms, the stone tile will have higher elasticity and elasticity in the field and in wet regions.

The fault of those who believe that the elastic glue can contain water, and the waterproofing layer is not needed. Each material performs its function, and the glue cannot replace the waterproofing. In this case, two concepts cannot be confused: water resistance and waterproofing. "Waterproof glue" means that they will not go into a wet environment, and they will not be able to resist water.

It is used for the following types of surfaces: brick, plaster, light blocks, cement or plaster plaster, dry ties from cement, dehydrated gypsum, warm floors. In the case of gypsum and plaster surfaces, pre-treatment of primer is necessary.

Used to glue a ceramic mosaic, borders and tiles, the longest side of which is no more than 40 cm., I.e. Suitable for all sorts of tile sizes from 2x2 to 40x40 cm. (10x10, 20x30, 25x40, 15x40, etc.).

If the floor heats up in the room, then it should be borne in mind that the surface of the room is expanding and compressed from temperature change. The surface of the electric heating floors is moving less, and the water is greater, because in the latter case the concrete voltage is higher. Fortunately, this movement is invisible naked, but the glue reacts to it. Therefore, in order to avoid facing the floor of the floor heated, only elastic glue is required for gluing. The surface on which the tiles are glued, should be clean and stable.

Before laying tiles on the floor heated floor, it is recommended that the heating is not turned on for at least three days to maintain the stability of the substrate so that the glue is not dried too quickly. After the tiles were lined with tiles, it is recommended to rotate the heating of the floor at least 2 weeks. In no case cannot be forced to dry.

Litoflex K80 - reinforced adhesive for ceramic granite and large formats of ceramic tiles. It has a higher adhesion and elasticity, quickly grasps and dries, is used both for internal and external work. Water and frost-resistant, environmentally friendly tile glue.

It is used for cladding concrete, gas-concrete bases, brick walls and partitions, cement screeds, cement-sand and gypsum plasters, drywall, plaster panels, warm floor systems, coatings from old tiles and waterproofing bases.

Predestly used for gluing ceramic granite, sweatured decorative elements and large-format ceramic tiles.

Buy glue for porcelain stoneware Litoflex K80 You can in our online store by reference

To understand how to choose and how best to buy tiled glue, we suggest familiarizing yourself with the following principles:

What glue is better suited specifically for your situation knows, first of all, the master (or technologist) itself, which leads the object.
If this does not have, and the surface that must be implanted is included in the list of surfaces described above, then in the case of C ceramic tiles (not granite) format up to 40x40, Litokol K17 glue is suitable. If we have ceramic granite or large-format tile more than 40x40, then the choice may fall on a slightly more expensive, enhanced glue Litoflex K80.
If the surface is non-standard and no "at hand" of the relevant specialist, then you can contact the manufacturer's website for extended documentation or contact their technologists.

We hope that the information presented above will help correctly answer the question of what better to choose glue for ceramic tiles or ceramic granite. In the meantime, we turn to the next, no less important partition.

How to calculate the glue consumption for the tile for 1 square meter

To begin with, let's clarify from what the glue consumption may depend on:

Format (size) tiles. The tile is less, the smaller the glue layer is applied to the surface.
The composition of the tile. For example, ceramic granite from white refractory clay, low water absorption (\u003e 1%), absorbs less glue than ceramic wall tile with water absorption of 10%.
The relief of the glued surfaces. Smoker surfaces require less glue than coarsest, uneven bases.
Wizard qualification and tool that it uses. There are many nuances, for example, there is an opinion that the use of V shaped spatula reduces glue consumption, and U-shaped form, on the contrary, increases.
Mark glue. In this article we are talking about Liocol and the flow rate, which they are declared in the accompanying documentation. The flow of other manufacturers can be varied, although not too much.
And a number of moments, such as temperature, air humidity, room ventilability, etc.

We pointed out the entire list of factors not to confuse you, and in order to clarify what exactly accurately calculate the glue can, except, a very experienced master or technologist. Well, for ordinary, not super professional calculations, we offer two simplified schemes:

On the site of any self-respecting manufacturer there is a calculator that will help correctly calculate glue consumption. In our case, the calculator from litocol is located.
There is averaged table at which Litokol K17 and Litoflex K80 glue consumption can be calculated independently:

Tile size, cm	Layer thickness, mm	Average flow, kg / m2
from 2x2 to 10x10	5 mm	3
from 10x15 to 20x20	8 mm	4
from 20x30 to 30x30	10 mm	5
more than 30x30	12 mm	6

An example of calculating the flow of glue for the tile

We need to fasten with a tile of 30x30 half an area of \u200b\u200b15 m2. From the table, we see that we spend 5 kg to the surface of the surface with a tile for each square meter. Our total area we have 15 m2, respectively, 5 kg / m2 * 15 m2 \u003d 75 kg of glue we will need on the entire room. Glue is sold by packages 25 kg. To find out how many glue packs we need to buy, we divide 75 kg / 25 kg / pack \u003d 3 packs - this is exactly this amount we will specify in the basket when ordering on the site.

In this simple mathematical operation, we will end our story that it happened 3 times the length than we planned :)

We sincerely hope that this article was useful for you and helped answer the question of how to choose and calculate glue for ceramic tiles. Please leave your questions or recommendations in the comments to this article.

Successful repair and successful choice!

Facing in the bathroom requires an individual approach to the selection of glue. This is a wet room without a high load. Glue for tile in the bathroom should have good adhesion to concrete and elasticity, because the warm floor is often used under the tile. The specific selection of the mixture depends on the format of ceramic tiles, the base type (plaster, plasterboard, etc.). Some mixtures are convenient in operation: have a long time of life of the solution and adjustment, while others, on the contrary, allow you to rub the seams after 4 hours. Why depends the choice of good mixture and specific examples you will find in this article.

Types of glue

On the counters of construction stores there are compounds:

on cement basis;
epoxy (reactive);
dispersion.

Cement

The basis is cement, and it is implemented in paper bags, packaged at 25-30 kg. A certain percentage of additives determines which properties to have tile glue for ceramic or porcelain tiles. There are universal mixtures, lightweight, strong, specialized.

In 90% of cases you will need cement tile glue.

Epoxy

Consists of two components and is divided into three categories:

with mineral filler;
with a subtle filler;
fluid;

This option is better to choose in a difficult situation, with a non-standard basis. When laying on strong cement bases, it is too expensive and inappropriate. If the bathroom has metal or wooden sites, which are not going anywhere, perhaps is your choice.

Dispersive

It is not suitable for working with concrete base, but for drywall is the most. The whole thing in high adhesion without deep penetration Inside the base.
Implemented in finished videothat increases speed and cleanliness, but it does not need it. The composition is a mixture of acrylic, a resin and the binder component.

The choice depends on the choice

Room

The feature of the bathroom is increased humidity. Glue for tiles should choose moisture-resistant. Even if the water absorption of plates and grouts for seams tends to zero, water can still penetrate, albeit in the form of steam, to the base and binding mixture. Therefore, it is better to progress. If we are facing by conventional ceramics, and still dodge the cement fugue, the fluid will constantly affect the adhesive layer. No, the tile will not fall off in a year, but the guarantee of durability in the context of the situation is the moisture resistance of the composition.

Wet spots on a new tile in the bathroom.

If you arrange the heated floors, choose the mixture, in the characteristics of which there is a heat resistance. It is much more important than the previous item. The omission of this aspect is guaranteed to destroy the cladding.

Ceramics

Size matters. Or rather, the weight associated with the gabarites of the tile. The glue needs to withstand the pressure of the mass, and therefore the requirements for adhesion increase with increasing plate format. The fight against gravity becomes more intense if the tile is made of porcelain stoneware. The low porosity of the material does not give a binding mixture to penetrate the ceramics, forcing the glue to stay on the plane of the tile. Universal mixtures are not suitable for laying large ceramic granite, you need to take a high grip glue: 1.3-1.5 MPa.

Base

What glue to choose if the surface is plastered cement-sandy solution? And if we were trimmed with plasterboard? The type of foundation affects the choice. One thing is a twenty-sentimeter ceramic tile, laid on a cement screed, another - 60x60 porcelain stoneware.

All these factors are combined with each other, forming the need for greater or lower glue strength. Affects adhesion and layer of glue. Well, when in the "liquid", only applied, it is equal to the thickness of the tile. With increasing layer, its capabilities are lost, he has to keep not only ceramics, but also himself.
From plywood and extruded polystyrene foam.

Examples of glue compositions

Video instructions for choosing glue with examples:

Ceresit.

Cerezite can be found in any construction store. This is one of the most popular manufacturers of dry mixes in Russia, so it is easy to run into a fake.

The most popular in the Ceresit lineup is the composition - see 11. Despite the versatility and associated with this skepticism, the glue has proven itself in working with porous tiles and a typical base.
The mosaic is better glued to cm 115 - a white mixture with improved indicators.
The tile up to 40x40 can be laid on cm 16.
For outdoor porcelain stoneware SM 119.
CM 117 will take everything, but the cost of the bathroom is not justified.

Unisa

The perfect solution for the shower room is a unice pool. Moisture-proof and heat-resistant, it will cope with liquid, and with an increased temperature, if a warm floor is planned.
Unisa Plus is recommended, in particular, for bathrooms. It is not so specialized, but the glue of moisture and thermosetics and has high adhesion.

Litokol

In the line of this manufacturer, many suitable compositions. Moisture resistance have all of them.

Litostone k98 / k99. Glue has high adhesion, "works" with porcelain stoneware and natural stone - An ordinary ceramic tile of its capabilities is enough with a margin. You can lay the tile on the tile, on the heated floors.
Litoplus K55. White glue for glass mosaic.
Litokol x11. One of the uses of the mixture is pools.

Knauf.

Flisen plus. It has high coupped properties.
Flisen Flex. Standard for a good mix set: porcelain stonework, tile on the tile.

Typhoon

Lux Plus. Not better and no worse than others, it is used for laying ceramic tiles in rooms with high humidity.

Vetonit.

Ultra Fix - suitable for bathrooms and pools with any typical bases. Withstand overall porcelain tiles.

What tile glue to choose? What is the difference? Other things being equal - cost. Price plug on the mixtures described: 230-1000 rubles. In other cases, differences are made in an individual set of characteristics, relevant in various situations. Standard bathroom and typical tiles have enough ordinary universal mixtures with 0.8-1.2 MPa adhesion.

To say exactly what tiled glue is better, only an experimenter, who was experienced by the modern compositions for years. Do not bother over with an unnecessary choice, but also do not get weak mixtures. Basically, look at the temperature moments, the format and structure of the plates and aspects associated with the atypical base for the tile base. Moisture resistance is important, but any glue from the list will satisfy the need for wet premises in the reliable composition.
