Tile adhesive bulk weight. How to calculate the consumption of adhesive for tiles. More about the spatula and the thickness of the adhesive surface
One of the first questions that arise when buying tile materials used in the work is how much tile adhesive is consumed per 1 m2.
Since on the basis of this value it is possible to calculate not only the volume of the required material, but also its cost. It is, in principle, impossible to unequivocally answer this question, but it is quite realistic to calculate the approximate consumption of the solution per 1 m2.
How can I calculate the required amount of the mixture?
The first option that comes to mind is to find out about the required amount from the one who releases it. For a particular manufacturer, there are norms for the consumption of tile adhesive from the condition of a constant thickness of the applied mortar. These data are indicated on the packaging and are indicative for the calculation. The table below shows the characteristics of the most popular brands of glue. The spread of values is due to different compositions of mixtures and type of destination.
Options for an approximate calculation of the amount of tile adhesive
As is clear from the presented table, the values are approximately the same and say little about anything. It is better to estimate the consumption of tile adhesive per 1 m2 on the calculator, which is presented by each manufacturer on its website.
In order to use this service, you need to know the area of \u200b\u200bthe room, decide on and select the type of mixture. As a result, you will be given the result in kilograms.
Another simplified version of the calculation for optimal conditions applications: half the thickness of the panel is multiplied by the consumption of the solution indicated on the package, the result will be the desired consumption of glue per 1 m2.
To correctly determine the required amount of the mixture, you need to take into account all the factors affecting this value.
Factors Affecting Adhesive Consumption
The first thing that determines the consumption of the mixture is the type of surface and its general condition. The smoother the wall and the less bumps and cracks on it, the less glue goes. That is why professional builders recommend pre-preparing the base with a less expensive finishing material type of plaster.
In addition, the reverse side of the tile can also have an uneven surface, and then an additional layer of mortar is applied to it.
The next parameter that determines the required amount of glue is the material of execution of both the wall and the tile itself.
Each material has its own porosity, depending on which it has a certain absorbency. For example, concrete walls absorb the least mortar. To reduce the consumption of tile adhesive per 1 m2, the base is carefully treated before
Tiles are also made from different materials. The smallest amount of glue disappears on porcelain stoneware panels, the largest porosity in cotto tiles.
The size of the panels also plays a role, the larger the tile, the thicker the layer should be.
Much depends on the method of installation and the professionalism of the masters. The more experienced the finisher, the thinner the layer of glue he can put without losing the quality of the fastening.
Varieties of glue
Before determining the consumption of tile adhesive per 1m2, it is necessary to choose which composition will be used. There are three main types of tile mix:
1. Dispersion - a ready-made composition, it is extremely convenient because you do not need to waste time on its preparation. It is good because it has ideal plasticity and viscosity, which allows applying the solution in an optimally thin layer.
2. Cement-based adhesive, the most inexpensive mixture that is sold dry and needs to be diluted. Thanks to cheap components, it is very popular and is used in 80% of cases. This type has its own way of calculating consumption, approximate, but giving at least some idea of the required amount. To determine the consumption, it is necessary to know the thickness of the adhesive layer, which is calculated based on the size of the tile. We multiply the thickness by 1.3 (this is the average weight of the tile adhesive) and we get the desired result.
3. Epoxy mix is commonly used by professional finishers as it requires some experience to make. For dilution, a special catalyst is used, which provokes a chemical reaction.
Spatulas used at work
A lot also depends on the size and type of spatula. To apply the solution, a spatula of a certain shape is used. If it is incorrectly sized, then the consumption of tile adhesive per 1 m2 increases significantly.
1. Adhesive consumption directly depends on the angle of the spatula during application, the larger the slope, the greater the consumption.
2. Most of the glue is consumed when applying the mortar with a square-toothed trowel, the most economical option is a V-shaped tool.
So how much glue do you need to buy?
Experts suggest taking 10 kg of glue per 1 m2 with a layer thickness of 10 mm as the norm. Even if you do it yourself, it will be more than enough. In order to reduce the consumption of tile adhesive per 1m2, the advice of professionals suggests carefully studying the technology of applying the solution and following the recommendations from the manufacturer.
Construction work involves the use various designs, some of them need to be fixed with a quality mounting tool - glue. For each material, a different type of substance is used to ensure the strength of the fasteners. The most popular building adhesives are:
Functional features and weight of tile adhesive.
Modern design very often uses tiles as additional interior elements, both indoors and in building cladding. The market can offer many options for tiles and mosaics. In order for the tiled masonry to serve for a long time, instead of the usual solution, you need to use specialized adhesives.
Adhesive mixtures have a wide range. The diversity is due to the functions that they are able to perform:
For a qualitative result, it is necessary to choose the right remedy and the quantitative need for it. Specific gravity glue varies from 1.3 g/cm3; up to 1.35 g / cm3;, but there are exceptions (depending on the brand and manufacturer). Thus - per 1m² tile adhesive weight 5 kg of dry mix will be required.
Important characteristics of the porcelain stoneware adhesive
Porcelain stoneware slabs are durable, heavy and dense structure. Therefore, for quality styling, it is necessary to use a base with a high degree of adhesive power. The main parameters, when choosing it, will be: the weight of the tile that it can hold, and the degree of adhesion strength. Successful work with porcelain stoneware, implies high adhesion (adhesion to the surface) and plasticity of the adhesive solution. In addition, it is important to pay attention to the layer of the agent when laying floor structures - it must be equal to the thickness of the tile itself.
Often weight of glue for porcelain stoneware, in a packing bag, is 25 kg. Mixture consumption, with a thickness of 1 mm = 1.3 kg / m3;. Usually the composition includes: fractionated sand, modifying additives and high-quality cement. This product is environmentally friendly.
Epoxy adhesive for building purposes
Epoxy adhesive includes a base and a catalyst mixed immediately before use. When using EC, one should be aware of the increase in the amount of consumption of the substance, with an uneven surface or deformations.
Epoxy adhesive weight calculate like this:
WEC = Density of adhesive x (S tiles + Thickness of the applied layer)
It is important to consider the porosity of the decorative parts. Sales consultants will help you correctly calculate the need for materials so that the result will meet expectations.
Weight of building glue PVA
PVA glue for construction purposes is able to glue various materials: paper, wood, cardboard, leather, linoleum, plastic, laminate, glass and tiles. It is convenient when assembling furniture, has significant stability at high temperatures and dynamic loads. Suitable for carpentry processes, does not leave marks and is very elastic.
pva glue weight in a packing container, is 0.5 kg. Substance consumption is economical - within 100-900g/m². It is inexpensive and waterproof. It must be applied with a brush, considering temperature regime. Can be used to strengthen the adhesive mixture, increase its viscosity and greater adhesion.
Glue is required for laying tiles. Probably everyone knows this. But how much is needed? 1 bag of 25 kg? 10 bags of 5 kg? Often the decision is made at the last moment in the market or in the store and you have to buy as much as the seller said. Is he right or not? In another situation, your foreman buys as much glue as needed (he knows for sure), gives you a number, but you can’t check it in any way. Or you want to plan all the repair costs in advance (a useful but utopian activity) and calculate how much the installation will cost you. What to do? How much glue do you need?
First the basics: tile adhesive is usually measured in kilograms. The amount you need is determined as the consumption of glue for one square meter laying, multiplied by the total number of meters. Everyone usually knows the laying area, so it remains to find out how much glue is required per square meter. There is no definite answer to this question, but we will help you figure out roughly how much glue you need.
To answer this question, you need to know the following:
1) Type of glue
Typically, tile adhesive falls into 3 broad categories: cement based adhesive, dispersion adhesive and epoxy adhesive. In the first case, you buy a bag of cement (with different kind additives) and dilute it with water or a latex additive. This is the most popular option: economical and not difficult to work with. The consumption of such glue on average keeps in the range from 1 to 1.9 kg per square meter per 1 mm of adhesive thickness. (For example, 1 kg per m2 for Eunice Granite glue, 1.5 kg per m2 for Litokol K66 glue and Hercules Basic glue, etc.) In the second case, you buy a ready-made liquid mixture (based on resin), which does not need to be diluted with anything. In the third case, you buy liquid composition resin and catalyst. You need to mix both components, a chemical reaction will occur and as a result an adhesive solution is formed (this is a little more complicated, but such a composition is not afraid of water and cold, is not subject to shrinkage, cracking and sets perfectly to the surface). The total amount of such a mixture in kilograms is incorrect to compare with the consumption of a cement-based adhesive mixture.
2) Tile size
Generally, the larger the tile, the larger the adhesive layer should be. As a rule, for small tiles (up to 10x10 cm) for cementitious adhesives with thin-layer laying, this layer is slightly less than 2 mm. For tiles with sides from 20 to 30 cm, the layer thickness is most often kept within 2-3.5 mm, for tiles from 30x30 to 50x50, the layer can be from 3.5 to 4.5 mm and for tiles large sizes, the layer can be 4-5 mm. For large tiles (from 60 cm) it is also recommended to apply a layer of adhesive (about 1 mm) on the back side of the tiles.
The given dimensions are approximate, it is quite possible that you will lay 45x45 cm tiles on a much thinner layer. It is important to consider other factors as well.
| About spatula size and glue thickness Most often, when buying glue, the technical information for each tile size will indicate not the glue layer in millimeters, but the size of the spatula teeth that the factory recommends for application. For example: for a 30x30 tile, use a spatula 8, and for a 50x50 tile, use a spatula 12. Not a word about the layer in mm. Why is this happening? Because measuring the adhesive layer in millimeters during application is not an easy task, how and with what will you measure? In addition, if you apply an even layer of glue, it is likely that it will visually appear even to you, but in fact it will have differences in height. If you lay the tile on such an uneven adhesive surface, you will most likely get air holes in some places under the tile, which will sooner or later cause the tile to chip off. Therefore, factories recommend first applying glue with the smooth end of the spatula, and then combing and leveling it with a jagged edge. The most commonly used trowel notch sizes are 6, 8, 10 and 12 mm. The dimensions of the spatula are given, each factory knows the properties of its adhesive, so it is much easier to predict the exact layer that you will lay down. Therefore, you can often see in the instructions the consumption of glue in kg, depending on the type of spatula. (For example, for Ceresit CM12 glue for 30x30 cm tiles, the instructions recommend using a spatula with 10 mm teeth, and the glue consumption is immediately given at 4.2 kg per square meter). However, do not think that when using a spatula with 8 mm teeth, you will get an 8 mm layer of glue. 8 mm is the initial height of the ridges that a 90 degree spatula would leave behind. But, firstly, you will lead the spatula at an angle, and the initial height will be less, and secondly, when you put the tile on top, it will press the glue with it and it will be distributed over the entire surface. Typically, the layer of adhesive will be in the range of 0.3 - 0.5 of the dimensions of the trowel teeth. For example, for an 8 mm spatula, the adhesive thickness can be 2.4 - 4 mm. This proportion is approximate, since you can put the glue at different angles, besides, different glues have different properties, and only the glue manufacturer can tell you what height of glue will be obtained using a given spatula. |
3) Type of tiles
The back surface of the tile absorbs the adhesive. But different kind material differs in porosity - tiles self made and cotto are very porous, they absorb more glue. Glazed industrial tiles absorb less, and porcelain tiles even less. Most often, manufacturers produce special adhesives for each type of material that takes into account these features. But there are also universal adhesives, so you will need to account for the difference in absorbance between different materials. If you are laying stone, often manufacturers will also ask you to apply an extra layer of adhesive to the back of the material.
In addition, it is important to pay attention to the evenness of the back surface of the tile. Handmade tiles and clinker often have an uneven back surface, so it is recommended to apply an additional thin layer of glue on it. This will increase the expense.
If you plan to lay tiles of different thicknesses on the same surface, you will have to compensate for this difference with glue. Get ready for that. that consumption will increase.
4) The base on which the laying is carried out and the technology of laying the tiles
Before laying, you need to know the condition of the surface on which you will lay the tiles. Ideally, it should be an absolutely flat plane, without differences in height. In practice, most often there are 2 situations: in the first case, the surface is maximally leveled and the height differences do not exceed 3 mm. In this case, you can lay the tiles using the thin-layer laying method - this means that the adhesive layer will be minimal, and the adhesive itself will only be used to adhere the tile to the base. Most often in such cases, the adhesive layer will not exceed 5 mm (and will be kept within the limits indicated above). But the total consumption of glue in any case will depend on differences in the height of the base and irregularities (which it will fill).
In the second case. the surface can be complex and uneven. There are adhesives that simultaneously level the surface and glue the tiles to the base. Usually they are capable of height differences of up to 30 mm. This technology is called thick-layer laying and the adhesive layer in this case will be determined by the presence and nature of irregularities and can reach up to 30 mm. Naturally, with this method of laying, the consumption of glue will be much higher.
Quite often, this method is used when laying tiles that have large differences in thickness (for example, this method is suitable for laying clinker with a strongly profiled back and handmade tiles with an uneven surface. If you try to lay such an uneven tile on a thin layer of adhesive, the consequences will be depressing: the final surface may be uneven, the tile may not stick due to voids, etc.)
Accordingly, you must know exactly how you will be laying before calculating the consumption of glue. The smoother the surface, the less glue is needed and vice versa.
In addition, one should take into account the factor that the bases on which the laying is carried out have different porosity. For example, a relatively porous base of cement mortar absorbs more adhesive than a concrete slab, so the consumption of adhesive will be greater.
And one more thing: when laying on a vertical surface (especially external facades), it is often recommended to apply glue not only to the base, but also to the back of the tile for better adhesion and to avoid the appearance of voids under the tile. In this case, the consumption of glue will increase and you should take this into account.
5) Brand and composition of glue
In the composition of adhesives different brands various additives are included (to give greater adhesion, elasticity, change in setting speed, resistance to creep, temperatures, etc.). All this changes the density of the adhesive, so two 25 kg bags can contain a different amount of material, which, accordingly, changes its consumption. In order to more accurately calculate the material consumption, it is better to know the manufacturer and the name of the adhesive in order to be able to check its consumption according to the information declared by the manufacturer. (For example, the standard consumption rate for Eunice Granite glue is 1 kg for each mm of glue, the Litokol K80 norm is 1.35 kg for each mm. With an adhesive thickness of 4 mm for an area of 20 meters, the difference will be (approximately, other things being equal) 20 kg (80 kg vs 108 kg) So if you want more accurate calculations- be sure to check the manufacturer's data.
6) Weather conditions
The normal temperature for laying tiles is from +5 to +40 degrees Celsius. Ideal - in the region of 18-24 degrees. The higher the temperature at which you lay the tiles, the more water evaporates from the surface of the adhesive and the greater its consumption. At low temperatures (below zero), the adhesive begins to deteriorate and it is extremely difficult to predict its consumption. It is also important to pay attention to the wind. If you are laying tiles outdoors, with a strong wind, moisture will again begin to leave the surface and the adhesive consumption will increase.
7) Technique of work and qualification of the stacker
Glue consumption depends on how you use the tool. At different angles of the spatula, the thickness of the applied adhesive changes (for example, at an angle of 60 degrees, the consumption of glue can be greater than at an angle of 45 degrees. The difference can be up to 25 percent). Likewise spatulas with different form The teeth distribute different amounts of glue: a V-shaped trowel usually distributes slightly less glue than a U-shaped trowel, which in turn distributes less. than a spatula with square teeth. If you are laying a tile for the first time, then the consumption of glue may differ from the standard one due to the fact that you either train, or violate the technology, or for some other reason, part of the glue you have goes to waste. It is always better to buy material with a margin in this case, so as not to stop laying in the middle of the process.
Calculation of the required amount of glue
The easiest is if you know exactly what kind of glue you need. For example, you have been laying tiles for years and know exactly what you want Eunice 2000 or Mapei Granirapid. It is enough to go to the manufacturer's website and find the calculator section (there are such sections on the websites of all manufacturers). In the calculator, it is enough to fill in the size of the tile, the area of \u200b\u200bthe room and the brand of glue, click on the calculate button - and you will get a ready answer in kilograms. This figure can then be increased if you know for sure that you will use glue to level the height between the tiles, work in conditions where the back surface also needs to be covered with glue, and under other circumstances that increase consumption.
If you don't know yet what kind of glue you'll be using, but want to estimate repair costs, use the numbers above. We will assume that you use tile adhesive based on cement (this is the most popular and easiest option). Then you can take the average temperature in the hospital - the consumption of glue is 1.3 kg per 1 mm of the glue layer. Multiply by thickness. glue. Let's say you lay a 30x30 cm tile on the floor. Then, with an average layer of 4 mm (see paragraph about the size of the tile), the adhesive consumption will be 5.2 kg per 1 m2 of installation. If you need to lay 20 meters of tiles, you will need 20 * 5.2 = 104 kg of tile adhesive. If you decide to lay a 10x10 cm tile on the same area, you will need 1.3 * 2 * 20 = 52 kg of glue. If you decide to lay a 60x60 cm tile, then you will approximately spend 1.3 * 6 * 20 \u003d 156 kg of glue
It is important to understand that this value is very approximate, and based on it, you cannot go to the store and order glue. We repeat once again that adhesives are different, they all have different properties and consumption, so it is better to at least know the brand of adhesive. But this figure will help you navigate the costs and planning, at least the final result is unlikely to be ten times more or less.
And the third way, which is more suitable for sellers in a tile store. Suitable if the buyer asks roughly how much glue is needed in general (without details, for an estimate). You need to take half the thickness of the tile in mm and multiply by the average consumption of glue per mm of the brand you are selling. If you do not know the expense or several brands - multiply by the average for the hospital 1.3. Typically, industrial tiles of small sizes are quite thin (5-6 mm), medium-sized porcelain tiles have a thickness of 10 mm, and thicker porcelain tiles - from 12 mm. Therefore, for porcelain stoneware 45x45 cm (10 mm thick), we get 5 * 1.3 = 6.5 kg per meter, which will give 130 kg per 20 meters and will be relatively close to the truth. Of course, you can’t invoice according to such criteria, but at least you can name the order.

Working with tiles as facing material requires certain skills and knowledge. Depending on where the tiles will be glued - outdoors or indoors, in the kitchen or in the bathroom - both the tile itself and the tile adhesive are selected.
About what types of tile adhesive are and how to correctly calculate its consumption, we tell in our article.
Types of glue
There are two main classifications of tile adhesive - according to properties and composition. Let's go over both briefly.
Types of tile adhesive by properties
Fast curing adhesive. Hardens within three hours after mixing. The premises where the tiles were laid on the quick-hardening adhesive can be used immediately after the completion of the work.
Where is the best fit - Laying an apron made of ceramic tiles in the kitchen.
Leveling adhesive. Designed for tiling uneven surfaces with a height difference of up to 5 mm.
Where is the best fit - cladding of balconies and terraces with ceramic granite.
Elastic adhesive. Compensates for deformation of the base and protects the tile from cracking. For example, during cyclic heating / cooling (underfloor heating), or from an accumulating load (pool bowl).
Where is the best fit – lining with mosaics of the internal surfaces of the pool.
Heat Resistant Adhesive. Withstands heat up to 600°C and is used where there is an open flame.
Where is the best fit - lining of a fireplace or stove with clinker tiles.
Frost-resistant glue. Differs in resistance to influence of moisture and low temperatures.
Where is the best fit - gluing facade tiles on the basement of the house.
Thick adhesive. Used for interior tiling with large-format tiles or artificial stone for which an adhesive layer of 10-12 mm is required.
Where is the best fit - decoration of the hall country house marble slabs.
Universal glue. Due to the average characteristics, it is suitable for a wide range of works, including indoor and outdoor.
Where is the best fit - laying floor tiles in the hallway of the apartment.
Types of tile adhesive by composition
Single component tile adhesive. The basis of the adhesive is cement, which is sometimes supplemented with a plasticizer to increase the life of the finished mixture.
Delivery format - dry mix.
Two component tile adhesive. Available in polyurethane and epoxy. The first consists of a polyurethane base and a hardener. The second is made of epoxy resins and a catalyst.
Delivery format - pasty base and liquid hardener/catalyst.
Acrylic tile adhesive. Ready-made composition based on acrylic, which does not need to be kneaded additionally.
Delivery format - mixture in the form of a paste.
How the size and type of tile affects the choice of adhesive and its consumption
A tile is defined by two key characteristics: size and type.
The size of the tile determines which tool you will use when laying it. Tile adhesive is recommended to be applied with a notched trowel. It is the height of the teeth in the spatula that directly affects the consumption of glue and is used in calculations. The logic is simple - the higher the height of the teeth, the greater the consumption.
If you do not yet know which notched trowel will be used for laying the tiles, but have already decided on the size of the tiles, you can use this correspondence table:
|
Tile size |
Spatula teeth size |
|
up to 10x10 cm |
|
|
up to 15x15 cm |
|
|
up to 25x25 cm |
|
|
up to 30x30 cm |
|
|
from 30x30 cm |
The type of tile, material and purpose, in turn, affect the choice of type of tile adhesive.

Calculation of consumption of tile adhesive
The basic consumption of tile adhesive is indicated by the manufacturer on the packaging. As a rule, this is a standardized consumption in kilograms per square meter with an adhesive layer thickness of one millimeter.
S- the area of \u200b\u200bthe room / surface where the tile will be glued;
r- basic consumption per 1 m2 with a layer of 1 mm,
h is the height of the trowel teeth.
Formula for calculating consumption in kilograms
Consumption = S x r x h/2
To translate the resulting value into bags of dry mix, you will need to further divide by the mass of one bag.
Example 1 . In the bathroom, 16 m2 of ceramic tiles are to be glued to the floor and walls. For the preparation of tile adhesive, a mixture of Bergauf Keramik is used with a basic consumption of 2.5 kg/m2. The mixture is packaged in 25 kg bags. The height of the spatula teeth is 8 mm.
Consumption = 16 x 2.5 x 8 / 2 = 160 kg or 7 bags
Example 2 . Porcelain stoneware slabs 45x45 cm in size are laid in a corridor with an area of 10 m2. Litokol Litofloor K66 thick-layer adhesive in 25 kg bags with a base consumption of 7 kg/m2 was chosen as an adhesive.
According to the correspondence table, we determine that we need a spatula with a tooth height of 12 mm.
Consumption = 10 x 7 x 12 / 2 = 420 kg or 17 bags
Consumption rates for popular brands
| Basic consumption (per 1 m2 with a layer thickness of 1 mm) |
Consumption for tiling 20 sq.m. surfaces with a layer thickness of 10 mm |

Finishing 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 tile adhesive per 1m2.
The amount of adhesive mass, regardless of the form of delivery (dry mix, ready-made solution), is determined in kilograms.
First, choose the type of glue: there are several of them, and they differ from each other in the basis.
cement
This type is the most popular for a number of reasons:- is cheap;
- easy to work;
- does not require leveling the base (the glue itself can play the role of a leveling mixture).
Supplied as a dry mix, designed to be mixed 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:
- outdoor tile material, which, due to the pronounced relief, has significant weight;
- facing problem bases: metal, glass, wood, plastic and others with a smooth surface.
Delivery form - ready solution. Consumption - 2 times lower than that of cement glue.
Epoxy
Another expensive special purpose adhesive.
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 permanently or permanently exposed to direct action of water;
- transparency: does not change the color of porous tiles and is suitable for gluing glass tiles;
- 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 thickness of the layer, the consumption is from 2.4 to 6.4 kg/m 2 .
polyurethane
Distinctive features of this composition:
- chemical resistance;
- moisture resistance;
- plastic;
- wide operating temperature range: from -55 0 С to +125 0 С.
Polyurethane compositions are used for lining and structures subject to deformations or vibrations.
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 one (heavy tiles) - 3.5 kg / m 2.
Type and size of tiles
Tiles of large sizes weigh a lot, therefore a thicker layer of glue is required for it.
An 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 or more, the adhesive mass, in addition to the base, is also applied to the tile - with a layer 1 mm thick.
The porosity of the base material also affects the consumption of glue - part of it is absorbed.
By absorbency, the varieties of tiles are arranged in the following order (from largest to smallest):
- "cotto" and handmade;
- glazed industrial production;
- porcelain tile.
When using a specialized adhesive mixture designed for a specific type of tile, the absorbency is not taken into account. This is true only for universal compositions.
Due to their significant weight, tiles made of natural stone, as well as large-sized ones, are covered with a layer of glue of 1 mm.
The thickness of the applied mixture when laying tiles is controlled not 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 tile, its thickness will end up being 30-50% of the height of the trowel notch. 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 instead of the recommended adhesive thickness the number of a notched trowel and the consumption for it. Example: Ceresit CM12 adhesive on a 30x30 cm tile, the instruction recommends applying with a spatula with a profile 10 mm high and reports that the consumption in this case will be 4.2 kg / m 2.
When applying the adhesive, it is necessary to take into account the angle of the spatula in relation to the surface of the tile. With an increase in slope from 30 to 60 0, the consumption of the adhesive mixture increases by 25%.
Tile laying technology
There are two installation methods:
- Thin layer. It is used when finishing prepared bases with a height of irregularities not more than 3 mm. The adhesive is applied with a thickness as indicated above - from 2 to 5 mm.
- Thick layer. Used on uneven ground. Consumption will depend on the nature and height of the irregularities.
For thick-layer laying, special adhesives are used, mainly cement, capable of working as a leveling mixture. The layer thickness can reach 30 mm.
Base type
Two characteristics of the base affect the consumption of tile adhesive:
- Porosity. The base also absorbs some of the adhesive, and this ability depends on its porosity. Cement plaster absorbs more, concrete less.
- Orientation.
The larger the tile, the more glue expended
When facing vertical bases, especially outdoor ones, it is recommended to apply glue also on the tiles, which leads to an increase in consumption.
Interior or exterior decoration
The consumption of glue 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 glue consumption, it is recommended to carry out Finishing work in calm weather, if laying is carried out on the street, 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 tiles
Three methods are used to determine the consumption of glue:
- Use the online calculator on the adhesive manufacturer's website. All well-known brands have them.
- 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 measuring 10x10 cm, for which a layer of 2 mm thick is enough, the need for glue will be 2.6 kg / sq. m.
- 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 with a thickness of 1 mm (for cement - 1.3 kg / sq. M).
Thickness of plain tiles 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 of 1 sq. m, a layer 1 mm thick (that is, a volume of 1 liter) will require the following amount of dry mix:
- 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, different volumes of glue are obtained from portions with equal mass.
