Decorating walls and floors with tiles begins with the purchase of materials, for which you need to know their quantity.

And if everything is clear with the basic materials - it is enough to calculate the surface area of ​​building structures, then things are more complicated with glue.

Its volume depends not only on the thickness of the layer, but also on a number of other factors. Next, we will discuss each of them in detail and learn how to calculate the consumption of adhesive for tiles per 1m2.

The amount of glue mass, regardless of the form of delivery (dry mixture, ready-made solution), is determined in kilograms.

First, they choose the type of glue: there are several of them, and they differ from each other in the basis.

Cement

For a number of reasons, this type is the most popular:

• is cheap;
• easy to work with;
• does not require leveling the base (the glue itself can act as a leveling mixture).

It is supplied as a dry mix intended for mixing with water or, if increased moisture resistance is required, with liquid latex.

Depending on the thickness of the layer, the need for it is 1.9 - 7.6 kg / sq. m (data for Ceresit glue).

Dispersive

An expensive type of adhesive, especially strong and solvent-free. Created for:

• external tile material, which has a significant weight due to the pronounced relief;
• cladding problematic bases: metal, glass, wood, plastic and others with a smooth surface.

Delivery form - ready-made solution. Consumption - 2 times lower than that of cement glue.

Epoxy

Another expensive special-purpose glue.

It has the following advantages:

• significant strength: in this respect it is not inferior to ceramic tiles;
• high adhesion: used for gluing smooth surfaces;
• absolute moisture resistance: used for cladding structures that are exposed to the direct action of water for a long time or constantly;
• transparency: does not change the color of porous tiles and is suitable for gluing glass;
• the ability to maintain working qualities at low temperatures;
• no shrinkage.

The adhesive composition is prepared immediately before use from two components - the base material and the catalyst. Depending on the layer thickness, the consumption is from 2.4 to 6.4 kg / m 2.

Polyurethane

Distinctive features of this composition:

• chemical resistance;
• moisture resistance;
• plastic;
• wide range of operating temperatures: from -55 0 С to +125 0 С.

Polyurethane compositions are used for cladding and structures subject to deformation or vibration.

Supplied ready-made or two-component (preparation required). With the smallest layer thickness (light tiles), the consumption is 2.5 kg / m 2, with a larger layer (heavy tiles) - 3.5 kg / m 2.

Tile type and size

Large tiles weigh a lot, so a thicker layer of glue is required.

The approximate dependence of these parameters for cement glue looks like this:

• tiles up to 10x10 cm: 2 mm;
• from 20x20 cm to 30x30 cm: 2 - 3.5 mm;
• from 30x30 to 50x50 cm: 3.5 - 4.5 mm;
• more than 50x50 cm: 4 - 5 mm.

With dimensions of 60x60 cm and more, the glue mass, in addition to the base, is also applied to the tile - with a layer of 1 mm thick.

The porosity of the base material also affects the consumption of glue - some of it is absorbed.

According to the absorbency, the types of tiles are arranged in the following order (from largest to smallest):

• "Cotto" and handmade;
• glazed industrial production;
• porcelain stoneware.

When using a specialized adhesive mixture intended for a particular type of tile, the absorbency is not taken into account. This is only relevant for universal formulations.

Due to its significant weight, tiles made of natural stone, like large-sized tiles, are covered with a layer of glue of 1 mm.

The thickness of the applied mixture when laying the tiles is not controlled by direct measurements, but by choosing a notched trowel of one size or another. Since the trowel is angled and the adhesive is then pressed down by the tiles, the thickness will eventually be 30-50% of the trowel's tooth height. That is, when using a spatula with a profile height of 6 mm, an adhesive layer thickness of 1.8 to 3 mm is obtained.

Manufacturers often indicate this, instead of the recommended thickness of the glue, the number of the notched trowel and the consumption for it. Example: Ceresit CM12 glue on a tile measuring 30x30 cm, the instruction recommends applying with a spatula with a 10 mm profile and informs that the consumption in this case will be 4.2 kg / m 2.

When applying the adhesive, the angle of inclination of the trowel in relation to the tile surface must be taken into account. With an increase in the slope from 30 to 60 0, the consumption of the adhesive mixture increases by 25%.

Tiling technology

There are two types of styling:

1. Thin layer. It is used for finishing prepared substrates with a height of irregularities not exceeding 3 mm. The glue is applied in the same thickness as indicated above - from 2 to 5 mm.
2. Thick layer. It is used for uneven ground. Consumption will depend on the nature and height of the irregularities.

For thick-layer installation, special adhesives are used, mainly cement ones, capable of working as a leveling mixture. The layer thickness can be up to 30 mm.

Base type

The consumption of tile adhesive is influenced by two characteristics of the substrate:

1. Porosity. The substrate also absorbs some of the adhesive, and this ability depends on its porosity. Cement plaster absorbs more, concrete less.
2. Orientation.

The larger the tiles, the more glue is consumed.

When cladding vertical substrates, especially external ones, it is recommended to apply glue to the tiles as well, which leads to an increase in consumption.

Interior or exterior decoration

Adhesive consumption is directly proportional to the rate of evaporation of water, which increases under the following conditions:

• strong wind (relevant for outdoor work);
• heat.

Therefore, to minimize the consumption of glue, it is recommended to carry out Finishing work in calm weather, if laying is carried out outdoors, and at a temperature of +17 0 C - +24 0 C. At temperatures below +5 0 C and above +40 0 C, tiling is not allowed.

Calculation of glue consumption per 1m2 of tiles

To determine the consumption of glue, three methods are used:

1. Use the online calculator on the glue manufacturer's website. All well-known brands have these.
2. If the brand of glue is still unknown, the calculation is carried out according to the above average indicators. So, for cement compositions, the average consumption with a layer thickness of 1 mm is 1.3 kg / sq. m, respectively, when laying tiles with a size of 10x10 cm, for which a layer 2 mm thick is sufficient, the need for glue will be 2.6 kg / sq. m.
3. A rough calculation used by sellers in stores: the volume of glue is determined by dividing the thickness of the tile by two, then the resulting value is multiplied by the average consumption of glue at a thickness of 1 mm (for cement - 1.3 kg / sq. M).

Thickness of usual tile most often it is 5 - 6 mm, porcelain stoneware - 10 or 12 mm.

Consumption rates

The consumption of dry mix of different brands is different. So, for application to a surface with an area of ​​1 sq. m, a layer 1 mm thick (that is, a volume of 1 liter), the following amount of dry mixture will be required:

• Eunice Granite: 1.0 kg;
• Litokol K80: 1.35 kg;
• Litokol K66: 1.5 kg;
• Hercules Basic: 1.5 kg.

When using dry mixes, an important circumstance is taken into account: due to differences in composition, from portions with equal mass, a different volume of glue is obtained.

Tile adhesive is the second most important material, the quality and properties of which determines the final result when tiling surfaces. The range of adhesives offered by modern manufacturers is wide, therefore, without knowledge of specific characteristics different types adhesives and comparing them with the requirements of GOST, making a choice in favor of a particular material is difficult.

In order for the tile adhesive to hold the cladding securely, it is important to maintain specifications mixtures according to GOST

To choose the right mixture, consider the following questions:

• general requirements for adhesive mixtures;
• groups of tile adhesives;
• properties and fields of application.

General requirements for tile adhesive

All types of adhesive mixtures for laying tiles must have a certain set of necessary technical characteristics, which, depending on the type of glue, may differ in value. Let's list these properties.

During operation (until the solution solidifies):

• ease of preparation;
• elasticity (should fit well on the surfaces to be glued);
• a sufficient life (the ability to work out the prepared amount of the mixture, fix the displaced tile until the glue hardens);
• high adhesion (adhesion of the solution to the surfaces of the material and base);
• low fluidity and resistance to slipping (holding tiles in place of installation on a vertical surface).

First of all, the glue should have an increased indicator of water and frost resistance.

After the tile adhesive has cured:

• compressive and shear strength;
• water resistance;
• heat resistance;
• frost resistance;
• resistance to chemicals;
• elasticity (the ability to take on the stresses of the cladding material arising from temperature changes).

Tile adhesives groups

According to the material of the components, all adhesive mixtures for ceramics are divided into 3 groups:

• cement-based formulations;
• water dispersion solutions;
• polyurethane adhesives;
• adhesives based on epoxy reactive resins.

Consider these groups and their subgroups.

Cement based formulations

Cement-based adhesives are a dry mixture of cement, sand and certain chemical components, the set of which can vary. Requirements for the technical characteristics of cement adhesive mixtures are set out in GOST 31357-2007 “Dry building mixtures on a cement binder. General technical conditions ", GOST 31358-2007" Dry building floor mixtures on a cement binder. Technical conditions "and GOST 4.233-86" Building solutions. Nomenclature of indicators ".

Tile cement glue refers to dry mortars

Characteristics

These adhesives, depending on the type, are intended for finishing external and internal surfaces with tiles made from natural and artificial materials. The standard packaging of the mixture is 25 kg bags.

The specific gravity of the dry material is on average 1.3 g / cm3, the density of the ready-to-use solution is 1.8 g / cm3.

The compressive strength of a fully cured adhesive, according to GOST, should be more than 10 MPa for universal compounds and at least 15 MPa for materials marked "Elastic", "With increased fixation" and "For floor".

The composition of the tile adhesive is mixed with water according to the instructions available on the packaging and is used in two ways - by applying to ceramics and laying on the surface of the base. The cement in the composition of the mortar is used in gray or white (for glass tiles and smalt mosaics) colors.

Adhesive solutions based on cement in the process of hardening retain water in themselves, after a day they allow grouting of the joints, a full set of strength with glue occurs within up to 2-3 weeks.

Shelf life

When buying such mixtures, you should pay attention to the date of release of the material, since after the expiration date, due to hygroscopicity, lumps form in the composition. The shelf life of such mixtures in the manufacturer's packaging is from 6 to 9 months, therefore, when buying, it is necessary to take into account that this period must expire before the completion of the repair - each expired month deprives the cement of 5% of its activity, and the polymer components may lose their properties altogether.

Cement adhesive mixtures, in turn, are divided into 2 subgroups:

• thick-layer (leveling);
• thin-layer.

Thick-layer cement-based adhesive mixtures

These mixtures are used to level the base under the tiles, if the differences in surface levels are 1-3 cm. The use of such compositions allows you to do without plastering the base and reduce the repair time.

To ensure a long service life, it is important to choose the right adhesive

The composition of the leveling adhesive, which includes cement, sand of various fractions and a set of polymers, ensures the durability of laying tiles from any material. The material of the “reinforced” brand is even used for the installation of cladding made of natural stone and porcelain stoneware, the specific gravity of which, due to its high density, is one and a half to two times higher than the weight of ordinary ceramics. Varieties of thick-layer adhesives are also produced for outdoor and indoor use, for rooms with high humidity and high temperature air.

The compressive strength of thick-layer adhesives after complete drying should be at least 10 MPa.

The disadvantage of leveling compounds is their strong shrinkage, which makes it difficult to calculate the need for material and does not make this method of leveling surfaces economical.

Cement-based thin-layer adhesives

Cement-based thin-layer adhesives are used for laying tiles on surfaces with level differences not exceeding 1 cm.

The adhesive layer applied to the back of the ceramic must be at least 5 mm. As in leveling mixtures, in thin-layer compositions, special additives are used that increase the individual characteristics of the material necessary for its use in specific conditions, but the specific gravity of the adhesive does not change significantly from this. There are also varieties of such adhesives with enhanced adhesion and strength for laying heavy tiles.

The compressive strength of thin-layer compositions after drying should not be lower than 10 MPa.

The advantages of thin-layer mixtures are low consumption (1-1.5 kg per 1 sq. M.) And shorter drying times than those of thick-layer mixtures.

The disadvantage is low moisture resistance in the absence of the “moisture resistant” marking, which forces the use of only moisture resistant mixtures.

Water-dispersion (polymer) adhesives are one-component aqueous solutions of polymer particles based on acrylic, latex or polyvinyl acetate (PVA). They are used for lining leveled concrete, plastered and plasterboard substrates with ceramic tiles, forming a waterproof shell. They are sold in plastic sealed containers of various sizes. The specific gravity of the ready-to-use solution is approximately equal to the weight of cement-based glue and is 1.3 g / cm3, the same value is taken as the density.

The technical characteristics of such adhesives are regulated by the requirements of GOST 28780-2004 “Polymer adhesives. Specifications "and GOST 12172-74" Phenol-polyvinyl acetal adhesives. Technical conditions ".

Dispersion adhesive is a composition of a water-based tile adhesive that includes acrylic or cellulose glycolic acid and special additives - chalk, latex

These materials are produced as thick white, colored solutions and pastes. Particles of glue suspended in water, when water evaporates or goes into the base, join together and form an adhesive film.

Instructions for use, as a rule, are presented in an accessible form on the container.

Advantages:

• ease of preparation for use;
• ease of application;
• bond strength;
• high moisture resistance;
• heat resistance;
• low consumption;
• absence of combustible components in the material;
• long shelf life when stored in a sealed container;
• environmental friendliness.

Flaws:

• impossibility of using for leveling surfaces;
• high price in comparison with cement adhesives.

Waterborne adhesive is the most common on the market

Polyurethane adhesives

Polyurethane based adhesives are one or two-component formulations... The technical characteristics of these adhesives must meet the requirements of GOST 30535-97 “Polymer adhesives. Nomenclature of indicators ".

Curing of one-component compositions occurs due to ambient moisture, which reacts with the components of the solution. Two-component substances harden when the components are mixed in a certain ratio.

It should be borne in mind that some types of polyurethane glue expand during curing and therefore are not suitable for laying tiles.

The material has high strength, sufficient elasticity and resistance to impact chemical substances... Effectively bonds the surfaces of even dissimilar materials (metal - glass, stone - wood) to each other, has almost zero moisture absorption, is insensitive to large changes in temperature (from -50 to +120 degrees Celsius) and pressure. The composition, in addition to a strong connection of materials in a short time, provides waterproofing of the base.

One-component and two-component polyurethane adhesives are industrially produced

The glue solution is applied with a brush or roller, not to the tile, but to the base. A necessary condition for the strength of polymer glue during use is thorough mixing of the solution and exact observance of the proportions of the components in a two-component design.

Material advantages:

• strength and durability of the connection;
• high adhesion to any surface;
• moisture and heat resistance (suitability for underfloor heating);
• resistance to chemicals;
• quick set of strength (the possibility of repairs in a short time);
• the ability to choose a variety of glue for specific conditions without overpaying for versatility;
• low consumption and no shrinkage;
• environmental friendliness after solidification.

Flaws:

• The need for skills in using this glue;
• The presence of a pungent odor in some species;
• Relatively high price.

Work with polyurethane glue should be carried out in protective gloves, and if the solution gets on the skin, wash it off in a short time with warm water and soap.

Epoxy adhesives are divided into two- and multi-component. A solvent-free epoxy adhesive is composed of a resin (base binder) and a hardener (liquid or powder activator). The binder is mixed in a certain proportion with the hardener, after which the mixture is applied to the degreased surfaces of the tile or base, and the product is glued in place.

A mixture of synthetic resin, mineral fillers and organic additives, the hardening of which is carried out by a chemical reaction

The setting time of the adhesive is approximately 20 minutes, and full curing takes place after a few hours. The surfaces to be bonded must not be porous. In difficult cases, to increase the strength, the epoxy adhesive is reinforced with dry powdered fiberglass.

These adhesives have high technical characteristics, and therefore are used in critical places and in industries with aggressive conditions of use of the finish.

The value of the compressive strength of compositions based on reactive resins should be at least 15 MPa.

Advantages:

• high strength with undemanding to the thickness of the adhesive layer;
• elasticity and high adhesion;
• waterproofness;
• frost resistance;
• long shelf life;
• low specific gravity (1300-1500 kg / m3);
• no shrinkage.

Flaws:

• flammability;
• high price.

Conclusion

Having made a decision on which type of glue to use for repairs, it is advisable to write out from GOST the characteristics that this material should have, and when buying, compare them with the data, albeit incomplete, indicated on the package. In this case, the shelf life is calculated from the date of production of the material, and not from the date of purchase.

Consumption of glue per 1 m2. Tile adhesive consumption rates.

There is nowhere in the repair without glue. Only now the question always arises, how much glue to buy, for example, for laying tiles? It seems that let there be more glue than not enough in the midst of the repair. This issue must be resolved at least to calculate the cost of repairs.

So, tile adhesive is usually packaged in kilograms. Therefore, you need to determine the consumption of glue per 1 square meter, and then calculate the total amount based on the area of ​​the room. But, an unambiguous answer to the question of how much tile glue is consumed per 1 square meter- No. It all depends on many factors.

1) Type of glue

Tile adhesive is divided into 3 groups: dispersion adhesive, epoxy adhesive and cement based adhesive. The most economical and simplest option for work is cement-based glue (diluted with water). Depending on the layer thickness, the average consumption of such glue is 1-1.9 kg. The dispersion adhesive is ready for use, it is made on the basis of resin and has a liquid structure. Epoxy adhesive also contains a resin to which a catalyst is added during use.

2) The second factor is the size of the tiles

The larger the tile size, the heavier it is, which means the thickness adhesive base should be more. So, for a 10x10 tile, a layer of cement glue of 2 mm is required, for a 20x30 tile - 3mm, for a 30x30 tile and more - 4-5 mm.

It is rather difficult to measure the thickness of the adhesive base. Even if in appearance, the layer of glue will look even, in reality it may not be so. So, rely on the size of the trowel teeth. So, for tiles of 30x30 cm, a trowel with 8 mm notches is suitable. When applying the glue, the trowel must be held at a 90 degree angle to the wall, then the thickness of the glue layer can be more accurate. For optimal distribution of the adhesive, it must first be applied with a non-serrated trowel and only then "comb through" the adhesive base. Therefore, the consumption of glue also depends on the size of the spatula (this is often indicated in the instructions). So for example, if you use Ceresit CM12 glue, then the consumption will be 4.2 kg per square meter, provided that you use a 10 mm notched trowel for 30x30 tiles.

3) Tile type

Different types of tiles, absorbs different amounts of glue. Porcelain stoneware absorbs least of all glue, a little more - glazed tiles, and finally, the porous surface of cotto tiles, tiles handmade also absorbs a lot of glue.

In addition, if the surface of the tile is uneven, then a small layer of glue should not be additionally applied, which will increase the consumption.

4) Another factor on which the glue consumption depends is the tile laying technology and the type of base

The ideal tile-laying surface should be smooth, even and free from cracks. In this case, the consumption of glue is minimal, because it is only necessary to ensure the adhesion of the tile to the surface.

If the surface has drops, cracks, then they are most often compensated by leveling with glue. There are specially designed adhesives that also level the wall, usually these are used if the difference in the differences is not more than 3 cm. Such glue is also needed for laying tiles that have differences on the back side, for example, for clinker.

Not only the back side of the tile has different porosity, but also the surface on which it is laid. The higher the porosity, the more the adhesive is absorbed. This means that additional costs will be required to securely fix the tiles. For example, concrete walls absorb less glue than a cemented base.

5) The composition of the glue and the brand are equally important

The glue contains various additives that give it certain properties (frost resistance, etc.). Accordingly, these additives change the structure of the glue, make it liquid or, on the contrary, thicker. Therefore, the consumption of glue of different brands, but the same volume, may be different.

So for each type of glue and for a specific glue brand its own consumption rate. For example, for Eunice Granite glue this norm is 1 kg, but for Litokol K80 glue the norm is slightly more - 1.35 kg.

6) Weather conditions also affect the technique of work

The optimum temperature for laying tiles varies between 18-25 degrees. But, the limit rates are much wider: from 5 to 38 degrees Celsius. The higher the room temperature. The more glue you need, because moisture evaporates very quickly. At subzero temperatures, the glue may lose its properties altogether.

7) The consumption of glue also depends on the technique of work, as well as the qualifications of the master

The amount of glue consumed depends on the technique of its application. So, when the trowel is tilted at an angle of 65 degrees, the glue consumption will be greater than at 45 (the difference is 20-30%). The shape of the spatula can also play a significant role. It is most economical to work with a V-shaped trowel, followed by a U-shaped trowel. More glue is consumed with square-toothed spatulas. And of course, the consumption of glue from a master with experience will clearly be less than that of an amateur. So if this is your first time laying tiles, it is better to buy some glue with a margin.

Calculation of the volume of glue

There are several ways to calculate the required amount glue.

Option one suitable for those who buy glue again, have already worked with it and know all the features of the glue consumption of this brand. In this case, when buying a certain glue, you can go to the official website of the representative's company. Very often, these sites offer a calculation option - a calculator. All you need to do is enter information about the tile size, the area of ​​the room and the specific type of adhesive. You will receive the final answer in kilograms.

Second option. We offer you an approximate calculation of the consumption of cement-based glue. We take the most favorable conditions, the consumption of glue weighing 1.3 kg. We multiply this value by the thickness of the glue layer (let's say that the tile has dimensions of 30x30 cm, then the thickness of the glue layer will be 4 mm). We get the result: 5.2 per 1 square meter. Accordingly, if you need to lay out 10 squares, then you get a consumption of 52 kg. For tiles of other sizes, only the thickness of the adhesive base changes. but given result it is difficult to call it accurate, if only because all adhesives are different. However, a rough estimate will give you some starting point.

Option three- suitable for those who urgently need to find out how much glue is required per 1 m2.

This requires the following parameters: half of the tile thickness (mm), the average consumption of the purchased glue. We multiply these indicators and get the result. This method is the most inaccurate, because even porcelain stoneware tiles from the same batch have different thicknesses.

The most popular brands of glue: consumption rates

We bring to your attention the average indicators of glue consumption per 1 square meter of the most popular, high-quality and demanded brands in the construction industry.

To begin with, consider the general average indicators, where the first indicator is the glue consumption rate in kg per 1m2, and the second indicator is the thickness of the glue layer.

Clay Unix: 1-1.16 kg per 1 mm of glue

In order for the tile adhesive to reliably fix the cladding, it is necessary to maintain the technical characteristics of the mixture in accordance with GOST. This task is largely on the shoulders of the manufacturer, but consumer awareness, proper use of the mixture and acceptable storage conditions are equally important.

The main criterion is the place of operation

Main types

The properties of tile adhesive differ depending on its composition. The components and their ratio directly determine the compressive strength and density of the mixture. For each type of material, GOST prescribes its own requirements.

Most often, the following adhesive compositions are used for laying tiles:

• Cement- this includes Portland cement, sand and various kinds of modifying additives. It is easy to handle, but it hardens rather quickly, so it is not recommended to prepare a large volume of the mixture.
• Dispersive- consists of epoxy resin and a special hardener. To work with it, a catalyst is introduced. This adhesive is characterized by properties such as strength and water resistance, therefore it is well suited for the bathroom.
• Polyurethane- stable polyurethane particles and hardeners are added to the composition of such a mixture. It is used even in a hostile environment.

Cement mortar is a common and simple option

Storage and shelf life

Depending on what the tile adhesive consists of, not only its characteristics differ, but also the shelf life. Given these features, two types are distinguished:

• dry powder;
• ready-made mastic.

For the first group of mixtures, it is important to observe the shelf life and storage conditions. The cement mortar should be kept in a dry place and not in direct sunlight. The average warranty is 6-9 months.

And here is the expiration date liquid glue depends on the moment the package is opened. In order for its properties to remain at the proper level and comply with GOST, it is undesirable to store excess mixture. A couple of months are allowed, but there is no quality guarantee.

Record the date of the opening, for example, with a marker on the bank

Glue weight

The indicator you are interested in is not the gross weight of the pack itself, but the average consumption of the mixture per one square meter of the surface to be coated.

Approximate consumption is also controlled by GOST standards. The calculations are based on the specific gravity of the tile adhesive used with a layer thickness of only one millimeter. This value is indicated on the packaging.

To calculate the volumetric weight of the tile adhesive required, determine the layer thickness of the compound. It depends on the size of the tile and the quality of the surface. The total weight per square meter is determined by simply multiplying the specific gravity by the layer thickness in millimeters. Then multiply by the surface area. This will help you determine the gross weight of the mixture you need.

Specifications

Tile adhesive has a different composition, but according to the standards, it must meet established requirements GOST:

• Strength is defined as the maximum allowable surface load and compressive forces.
• Density - measured in grams per square meter, additionally characterizes the weight of the mixture.
• Shrinkage is surface deformation.
• Viscosity - concentration of adhesive particles and the ability to fix the veneer without displacing the base.
• Drying speed - affects the shelf life, since the hardened glue cannot be used. Consumption - directly depends on the density. It is defined as the weight of the mixture per square of area.
• Elasticity - the composition should be well applied and not crumble.
• Water resistance - does not allow moisture to pass through.
• Adhesion - the quality of adhesion to various types of surfaces.

These are the main technical characteristics according to GOST, which you need to focus on when buying a mixture.

Viscosity and drying speed - main characteristics

Shrinkage

One of the most important indicators for determining the appropriateness of using a particular composition is the degree of shrinkage of the tile adhesive. Pay particular attention to this property when finishing the surfaces of newly erected buildings and refurbished coatings.

GOST sets the maximum permissible standards for a given property. Pay attention to this figure before buying glue. To ensure that the use of an unsuitable compound does not lead to the fact that after a year you will have to carry out repeated repairs, in most cases it is recommended to use a mixture with zero shrinkage.

When it comes to wood, purchase an elastic tile composition that can compensate for the movement of the base.

Density and compressive strength

The thickness of the adhesive layer determines its wet height. In this case, the weight of the composition is taken into account. This indicator indirectly demonstrates the presence of certain impurities in the solution.

Another parameter characterizes the adhesive for the tile in an already fixed state. Compressive strength is essentially the maximum allowable surface pressure during operation. The class of concrete is determined in the same way. The higher this indicator, the better the strength of the coating, and, consequently, it will last much longer, even under conditions of exerting a significant load on it.

Terms of use

In order not to degrade the quality characteristics of the tile adhesive, you need to handle it correctly.

The appearance and durability of the masonry

An important point is to determine the volume of the required mixture. Here they calculate the weight of the glue for the area to be treated and mix only as much as you have time to use before the components harden. Epoxy glue is more difficult to work with. It is diluted with a catalyst. Its high viscosity can make it difficult to apply.

The installation process involves the use of a spatula to spread the tile adhesive over the surface. The size of the teeth is matched to the thickness of the mortar. In case of serious irregularities, they are additionally applied to the tile itself. Too thin or thick layers will impair the styling quality. It is important to drive away voids and air accumulation under the tiles. Excess at the joints is removed immediately after tamping, before solidification.

It is possible to choose a suitable adhesive for tiles only on the basis of a thorough analysis of all its characteristics and comparing them with your requirements. Take into account the reputation of the manufacturer and the storage conditions of the goods in the store or warehouse. Correct use guarantees the quality of the cladding.
