Consumption of different grades of tile adhesives per 1 m2
It is quite difficult to accurately calculate the required amount of glue for a tile. But to acquire material “by eye” is undesirable. Subsequently, you will either have to buy it, or somehow get rid of the excess. There will be difficulties in determining the total cost of repairs, and as a result of the allocated funds, it may not be enough or, on the contrary, a surplus will form. It is necessary to calculate the flow rate as accurately as possible, but it is quite difficult to do manually. It is necessary to apply rather complex formulas, which are rather difficult to operate without having the appropriate experience. The consumption of tile adhesive per 1 m2 of tiles depends on many factors. This article will help you figure out which ones you need to focus on when making a preliminary estimate.
In the repair process, many problems have to be solved, on which the success of the whole event depends. It is necessary at the design stage to determine the nuances of decoration and the interior itself, and calculate the required amount of materials, in particular, tile glue. As much as possible accurately calculate the amount of glue needed will help a special service. The interactive calculator instantly performs the necessary calculations based on the parameters specified by the user. All calculations are made online based on special formulas. With it, you can determine in a second how much glue will go per square meter and how much the mixture will need.
In the table you need to specify:
the shape and size of the tile;
glue application area - outside or inside the building;
surface to be faced - walls or floor;
type of foundation - concrete, gypsum or cement plaster, waterproofing, the old layer of tile, stone or porcelain tile, gypsum board - ordinary or moisture resistant;
operating conditions of the future coating - heating, freezing, high humidity, contact with water;
type of cladding - ceramic tile, stone - artificial or natural, mosaic - ceramic, glass, metal, porcelain stoneware, wooden;
type of glue;
laying area.
Using the calculator you can get only averaged data. They are useful for rough preliminary calculations. If glue is purchased for facing large projects, it is necessary to check the material consumption on the surface area empirically. To obtain the correct indicators, it is necessary to understand that the type of glue, its brand and composition, the surface structure of the tile affect the consumption of dry mixeslaying technology and even the qualification of a specialist - tiler. Consider these factors in more detail.
Type of glue
To perform the facing works, the following types of adhesives are used:
on a cement basis - the most popular and affordable materials. They are supplied in the form of dry mixtures, which must be mixed with water before use, in accordance with the instructions on the packaging;
dispersion - the composition is sold in diluted form. Installation can begin immediately after opening the package. Excellent ductility and viscosity of the material greatly simplifies the work, so even inexperienced craftsmen can successfully use it. The composition is optimally suitable for the installation of thin tiles, because it has good adhesive ability;
epoxy - preparation of the mixture may cause difficulties for the beginner, therefore, in the absence of the necessary experience, it is better not to use it. The fact is that it is necessary to add a component to the solution that acts as a catalyst that triggers the start of a chemical reaction. When adding it, you must act very carefully and observe the exact dosage.
Size and type of tile
To calculate the amount of glue, the size, weight and type of tile coating are taken into account. The larger and more massive the cladding elements, the more thick the adhesive layer. If the optimal layer for tiles 20x20 will be 3 mm, then for tiles 40x40 can not do without a layer of 4 or 5 mm.
The glue consumption is also affected by the material of which the tile is made. This indicator is also worth considering, despite the fact that manufacturers indicate an average value. In fact, for laying tiles, a larger amount of the mixture is required than when facing porcelain tiles.
It is practically not absorbed into the last glue, due to which a minimal amount of solution is sufficient for its laying.Rough and porous materials, on the contrary, require the application of a thicker layer of material and in this case glue must be purchased with a margin.
Tile Laying Technology
In the process of laying ceramic tiles, a very important step is the preparation of the base, which includes:
alignment;
padding.
On a properly prepared surface there should be no drops, grooves, cracks. Correctly calculate the consumption of glue when laying the facing material on an uneven surface is very problematic. To eliminate the differences, you will have to put the glue in a thick layer, due to which its consumption will increase significantly.
Much more glue will leave if the base has a strong ability to absorb moisture. Water-based glue will have to be applied in a thick layer to compensate for absorption. That is why priming is an integral part of the cladding process, which allows you to strengthen the surface and limit the consumption of material.
Surface view
The porosity of the surface to be coated also affects the consumption of the material, so you need to choose a mixture, focusing on this indicator. The surface of the tile itself also plays a role. If it is porous or, moreover, relief, increased glue consumption cannot be avoided.
The amount of material required is affected by the type of substrate that is to be faced.
It can be a surface from:
concrete;
drywall;
brick;
a tree;
cement.
The surface of these materials has a different absorbency. For example, a brick absorbs an adhesive mixture much more strongly than concrete or drywall. The concrete base absorbs the least amount of glue compared to cement and especially wood. Therefore, when calculating, it is necessary to take into account the ability of the surface material to absorb moisture.
Water-based mixtures are absorbed much more intensely than epoxy compounds.
Temperature and weather conditions
When calculating the amount of glue, it is necessary to focus on the temperature factor, and take into account the microclimate in the room. For the use of adhesives, the optimum temperature is from 18 to 25 degrees Celsius. Failure to comply with these standards may lead to a violation of the consistency of the adhesive and its viscosity, although in the range from 5 to 38 degrees above 0, the quality of gluing is maintained. The temperature and humidity in and out of the room also affect the rate of evaporation of moisture from the adhesive. Due to this, the stages of solidification and adjustment of the position of the tile can be shortened or stretched.
Brand and composition of glue
Various types of glue contain all kinds of additives that can enhance the quality of the composition and give it additional properties. Certain additives are designed to increase the moisture resistance, adhesion and frost resistance of the material. These ingredients are able to increase or decrease the viscosity of the adhesive. A thick mixture can be applied with a thicker layer, therefore, its consumption will be higher.
When calculating the required amount of glue to perform work, it is necessary to take into account the number of these components and their characteristics. Information on this is contained in the instructions for use of the mixture.
Type of spatula
Spreading glue without a special spatula with teeth and observing a certain layer thickness is very difficult and subject to only experienced craftsmen. Manufacturers very often recommend a certain size of trowel teeth for a particular product. These parameters are indicated in the instructions for the adhesive mixture.
When laying tiles 30x30 cm, it is not recommended to use a spatula with a protrusion size of more than 8 mm, since it will be difficult to distribute the adhesive evenly on the surface. Glue consumption also depends on the height of the teeth. For example, when installing floor modules with dimensions of 40x40 it is allowed to use a spatula with a tooth of 10 mm, but you need to remember that this will require up to 4.2 kilograms of glue per square meter. mA spatula by 8 mm can reduce consumption to 3.9 kg per square meter. m
The shape of the teeth is equally important. Rounded protrusions allow you to reduce the amount of glue, unlike square.
Qualification and technique of the master
The professionalism and experience of the master is an equally important factor, which should also not be discounted. Keep in mind that by saving on services, you risk not only getting low-quality repairs, but also significantly overpaying for materials. An experienced tiler knows how to reduce glue costs thanks to a special application technique.
For example, it is unacceptable to take too long to fix the position of the tile. If the time allotted for adjustment expires, you will have to replace the mixture, which will double the amount of glue used.
To use the finished mixture, a certain time is allocated, after which the material will become unusable. Experienced craftsmen are well aware of this feature of tile adhesives and knead them in small portions.
Much depends on the angle at which the specialist holds a spatula in his hand when applying the composition to the surface. If the angle is 45 degrees, the material will be consumed much more economically. An angle of 65 or 75 degrees can increase glue consumption by 35%.
Beginners usually use less economical square trowels for laying. They are optimally suited for laying floors where a thin layer is unacceptable. For walls, it is more correct to use a tool with rounded protrusions, which can minimize glue consumption and create a thin layer.
Consumption rate and characteristics of glue of popular brands
When choosing an adhesive of a particular brand, special attention must be paid to the temperature range at which the manufacturer recommends tile work. Glues of most popular brands have a good supply of heat resistance. Often on packages you can see the permissible limit of + 90 degrees.Such materials are not recommended for use on a water heated floor, since in these systems a margin of heat resistance is required, which will ensure the integrity of the cladding even in the event of a breakdown of thermostatic units. They will be optimal for floors with infrared heating.
