For laying large-format tiles on floors, it is recommended to use adhesive for tiles Ceresit CM 12.

How to apply tile adhesive Ceresit CM 11:

Foundation preparation:
The base must comply with the requirements of SNiP 3.04.01-87 and have sufficient bearing capacity. The base must be dusted and cleaned of substances that reduce the adhesion of glue (efflorescence, fats, bitumen, etc.). Unstable spattering areas must be removed.

Walls should be pre-leveled with Ceresit CT 29 repair plaster not less than 3 days before fixing the tiles, and floors - with a leveling mixture of Ceresit of group CN. Irregularities up to 5 mm can be smoothed with CM9 glue no less than 1 day before fixing the tiles.

Typical substrates (Ceresit CM 11 adhesive)

Cement-sand and cement-lime plasters, cement-sand screeds (age more than 28 days, humidity less than 4%) are recommended to be treated with a primer Ceresit CT 17 and dry for at least 4 hours. Dense, clean, durable substrates must not be primed.

NOT Typical substrates (Ceresit CM 11 + CC83 adhesive)

Gypsum plasters (moisture content less than 0.5%), particle boards, cement-bonded particleboards, gypsum plasterboards and other boards (thickness more than 22 mm), lightweight, cellular or “young” concrete (age about 1 month, humidity less than 4%), cement -heated sand screeds should be treated with a CN 94 or CT 17 primer and completely dried (OSB boards should be treated with a CN 94 primer).

Stone and ceramic facings, water-dispersion coatings with good adhesion to the base, cast asphalt screeds must be treated with CN 94 primer and dried for at least 2 hours.

Performance of work:
To prepare the mortar mixture, a precisely measured amount of clean water (from +5 to +20 degrees) or CC 83 elasticizer diluted with water in a ratio of 2: 1 is taken. The dry mixture is gradually added to the liquid with stirring, achieving a homogeneous mass without lumps. Stirring is carried out using a mixer or drill with a nozzle for viscous mixtures at a rotation speed of 400-800 rpm. Then maintain a technological pause for 5 minutes to ripen the mortar mixture and mix again. The mortar mixture should be consumed within approximately 2 hours (with CC 83 elasticizer in 1.5 hours) from the time of preparation.

Cement tile adhesive is applied to the base with the smooth side of the toothed grater or smooth trowel and spread over the surface with the toothed side of the grater or notched trowel. The teeth should have a square shape, and their size is chosen depending on the format of the tiles (see table below). With the correct selection of the consistency of the mortar mixture and the size of the trowel teeth, the adhesive, after pressing the tiles, should cover at least 65% of the glued surface on the walls and 80% on the floors.

Attention! Do not pre-soak the tiles!

Clinker tiles can be fixed for 15 minutes ("open time") after applying glue to the base (with an elasticizer of 20 minutes). The tile is laid on the adhesive layer and pressed to the base. The position of the tile can be adjusted within 20 minutes after laying (with an elasticizer - 25 minutes).

Attention! Do not stack tiles!

The seam width is set depending on the tile format and operating conditions. The high fixing ability of the adhesive eliminates the need for gaskets between the tiles to ensure the same joint width.

For outdoor work and the installation of stone claddings, it is recommended to use the combined method of laying to increase the reliability of fixing the tiles: glue with a smooth spatula is additionally applied to the mounting surface of the tiles with an even layer of 1 mm thick. Adhesive consumption increases by 0.5 kg / m 2.

It is recommended to fill the joints with appropriate grouts for Ceresit tiles CE groups not earlier than 24 hours after laying the tiles. When using glue with the addition of an elasticizer, it is recommended to fill the joints with elastic grout CE 40 no earlier than 72 hours after laying the tiles.

Fresh glue residues can be removed with water, dried - only mechanically.

Recommendations:
Work should be carried out in dry conditions, at air and base temperatures from +5 to +20 degrees and relative humidity of less than 80%. All the quality indicators and recommendations set forth in the technical description are correct for ambient temperature and relative air humidity up to 60%. In other conditions, it is possible to change the time of consumption, adjustment and the open time of the glue, as well as the time the lining is ready to fill the seams.

Technical Specifications for Ceresit CM 11 Tile Adhesive with CC83 elasticizer:

Scope and variety of glues

Ceresit dry mixes are manufactured by Henkel and are used for exterior and interior use, for walls and floors, and various types of substrates. The range of tile adhesives is huge, there are universal and specialized tools on sale. All Ceresit compositions vary in scope, and for the convenience of determining the destination have the following markings:

• SM - building mixtures for fixing ceramic tiles,
• CB - adhesives for fragmentary repair of lined surfaces,
• ST - mixes for installation of external (front) thermal insulation.

The purpose of the funds is different, the user can always find the right solution. Standard adhesives of the SM brand have high adhesion with brick, concrete, and are used for laying tiles, mosaics, porcelain tiles indoors and outdoors (for example, “Cerezit SM 110”). Some adhesives due to moisture resistance can be used in the bathroom, other wet rooms. Elastic adhesives will help to fix the finishing material on surfaces prone to vibration, shrinkage. There are also special adhesives of the SM series for:

• large-format floor tiles,
• mosaics and marbles (white glues),
• clinker
• front tile.

The CT line includes ready-made products and dry mixes for breeding for outdoor use. The most popular among builders are such compositions:

• CT 84 polyurethane adhesive for expanded polystyrene (used in the installation of external thermal insulation of facades),
• CT 190 stucco-adhesive mixture (CT190 is used for the installation of mineral wool boards and the base plaster layer for facade insulation),
• CT 85 stucco mixture for polystyrene boards (for indoor and outdoor use).

In the series CB 10-100, acrylic and other mounting adhesives in cylinders are produced, with which they work indoors and outdoors. All of these Ceresit adhesives can be fixed only with tiles and heat-insulating materials, and for laying other coatings it is necessary to choose specialized compounds (for example, UK 400 for PVC and linoleum). Each glue has a certificate of conformity, confirming its high quality.

Instructions for use

Before using the Ceresit tile adhesive, you must carefully prepare the base. It is necessary to fully use the high adhesive performance of the solution. It is recommended to remove the old base as much as possible, to clean and level the surface.

Vertical surfaces should first be marked and the bar set at the level of the first tiled row. This will prevent the cladding from sliding in the first 6 hours of installation.

• After mixing the solution, immediately proceed to work. Apply with a flat spatula 200-300 gr. solution on the prepared plane.
• Toothed structure with a notched trowel. The depth of the grooves is adjustable depending on the size of the tile. The smaller the tile, the less unevenness.

• Apply the cladding element for 10-15 minutes. So that the solution does not have time to set. Tap a little with a rubber hammer in order to evenly drown the tile and release excess air.
• The volume of contact of the tile with the solution should be 60–80%.
• In parallel, lay adjacent sections leaving a distance of 1–5 mm. To keep the installation even, use crosswise dividers between the tiles.
• Remove excess glue immediately with a rubber spatula and warm water.
• Leave to full adhesion for 20–36 hours.
• After drying, fill the joints with grout.

Recommendations for use

• To apply cement tile adhesive, a notched trowel or notched trowel is suitable, in which the smooth side is used as the working side. The shape of the teeth should be square. When choosing the height of the tooth, they are guided by the tile format, as shown in the table above.
• If the consistency of the working solution and the height of the teeth are selected correctly, then after the tile is pressed to the base, the cladding surface of the walls should be covered with a glue mixture of at least 65%, and floors - 80% or more.
• When using Ceresit CM 11, pre-soaking tiles is not required.
• Butt laying is not allowed. The width of the seams is chosen, guided by the format of the tile and the specific operating conditions. Due to the high fixing ability of the glue, there is no need to use cross stitching, ensuring evenness and the same width of the tile gap.

In cases of installing stone cladding or performing facade work, combined laying is recommended, which implies additional application of the adhesive mixture on the tile mounting base. When the adhesive layer is formed (thickness up to 1 mm) by means of a thin spatula, the consumption rate will increase by 500 g / m2.
Seams are filled using appropriate grout mixtures under the CE marking after a day from the moment the lining is finished.
Water is used to remove fresh residues of the mortar mixture, while dried stains and smudges of the solution can be eliminated exclusively by mechanical cleaning.
Due to the content of cement in the product, an alkaline reaction occurs when it comes into contact with a liquid.

For this reason, when working with CM 11, it is important to use gloves to protect the skin and prevent it from reaching the eyes.

Features

Adhesives for laying Ceresit tiles differ in the scope of application, as can be found on the marking on the package:

• SM - mixtures with which the tile is fixed,
• SV - materials for fragmentary repair of cladding,
• ST - mounting mixtures, with the help of which they arrange external thermal insulation on the facades.

Glue Ceresit CM 11 - a material with a cement binder as a base, the addition of mineral fillers and modifying additives that contribute to improving the technological properties of the final product. Porcelain stoneware or ceramics are fixed on it when carrying out internal or external types of interior decoration at housing and civil facilities and the manufacturing sector. It is combined with any typical non-deformable mineral substrates: cement-sand screed, concrete, plaster leveling coatings based on cement or lime. Recommended for rooms experiencing constant or short-term regular exposure to the aquatic environment.

CM 11 plus is used for facing with ceramics or natural stone with dimensions of a maximum of 400x400 and a water absorption value of 3 percent. According to "SP 29.13330.2011. Flooring ”, it is also allowed to plant tiles on it (porcelain stoneware, stone, clinker) with a water absorption capacity of less than 3% for floor cladding without electric heating. In these cases, the composition is used exclusively when carrying out interior finishing work in premises for domestic and administrative use, that is, where operation does not imply high mechanical loads.

Area of ​​use

The described adhesive is intended for lining mineral non-deformable substrates like brick, plaster, concrete and cement. Surfaces that are supposed to be tiled can be in operation under conditions of periodic or constant exposure to water. Glue can be used in the arrangement of the underfloor heating system. This adhesive composition is also actively used when laying stone as well as ceramic tiles, the water absorption of which is 3 percent or higher.

Key Specifications

“Cerezit SM 11”, the technical characteristics of which should be read before purchasing the composition, can be used after kneading for 180 minutes. In order to know how much is needed for the work, it should be taken into account that about 1.7 - 4.2 kilograms will be needed per square meter. The final figure will depend on the thickness of the laid layer, as well as the material at the base of the decorative finish of the subfloor. It is important not only to choose the right adhesive composition, but also to observe the technology of its mixing. Thus, 0.24 liters of water will be needed per 1 kilogram of the mixture. And for 25 kilograms of dry composition, which is equal to one bag, you will need 5 liters of water. The master must observe the thickness of the recommended layer, which is 6 millimeters, when laying. Open time is 15 minutes, which is why it is important to lay the tiles until the mixture sets. The master has the ability to adjust the final position of the product after laying for 20 minutes.

Instruction for use

If you will use Ceresit SM 11 for laying tiles, the technical characteristics of which are presented in the article, it is important to take into account some of the nuances of the work. You can start grouting the joints one day after the completion of the manipulations on the lining. Do not start work if you cannot achieve the optimal ambient temperature, as well as the foundation. This range can vary from +5 to +30 degrees. As for the operating temperature, it varies from -50 to +70 degrees. If you need to take into account the quality of frost resistance, you should remember that Cerezit SM 11, the technical characteristics of which must be known before starting work, will be able to transfer 100 cycles of freezing and thawing.

Preparation of the base and method of use

Before proceeding with the application of the adhesive, it is necessary to clean the surface of dust, dirt, and oil stains. It is important to free the work surface from exfoliating areas, which may be represented by the old finish. If irregularities have been noticed, then they can be eliminated by applying plaster.Before you start lining, it is necessary to treat the base with a primer. Tile glue “Ceresit”, the technical characteristics of which will become known to you after reading the article, must be prepared according to the rules on the packaging. The dry mixture is poured into a container in which pure water is located. After you can start mixing until you can achieve a homogeneous mass. In this state, the mixture is left for 5 minutes, and then mixed again, then we can assume that the solution is completely ready for use.

Professional Recommendations

After the solution is ready, with the help of a notched trowel, it should be applied to the surface. Tiles are laid on the formed adhesive layer, after which the product is carefully pressed to the base of the wall or floor. It is recommended to store glue in a closed container for six months from the date of manufacture.

Main advantages

Ceresit CM 11 Plus, adhesive for attaching ceramic tiles, has a number of undeniable advantages. Among them, we can distinguish the absence of the effect of creep of the composition when used on a vertical surface. Among other things, the composition can be used at sub-zero temperatures. The mixture is so popular among consumers also because of the lack of restrictions on use in high humidity conditions. You can count on economical consumption when applying. Specialists and private masters emphasize that the glue is convenient in the process of preparation and application. “Ceresit CM 11” - adhesive for tiles, the properties of which are presented in the article, is completely harmless to human health, since it does not contain harmful substances and toxic impurities.

Additional properties

It is important to consider that the application of glue can be done on the plastered surface and cement screed, after the formation of each of which 28 days have passed. As for concrete substrates, it is possible to start work on such surfaces 90 days after the completion of work. In order not to encounter problems during operation, do not start manipulating the decoration of deformable substrates. This adhesive composition is also incompatible with products whose water absorption is less than 1%. If there is a need to lay tiles in rooms with high humidity, with regard to showers and bathrooms, the Ceresit CM 11 adhesive mixture, the technical characteristics of which are presented in the article, can be used only if the humidity is periodically increased, as well as intensive ventilation. It is important to properly prepare the bases that have large crevices and potholes. The craftsman must grind and level the surface using plaster or mineral filler.

Use of Cerezit SM 11 glue in tandem with an elasticizer

“Cerezit SM 11 plus”, the technical characteristics of which will become known to you after you read the article, can be used for arranging heated screeds on parapets, socles, entrance groups, outdoor stairs, terraces, balconies, as well as exploited roofs, however in this case, the adhesive must be used together with a CC 83 brand elasticizer. The mentioned additive is used when there is a need to apply the described adhesive on deformable substrates, namely gypsum boards, chipboards ah, and OSB. The combination of glue and elasticizer allows the composition to be used in indoor and outdoor pools and tanks. Experts recommend the use of such technology on ceramic claddings when carrying out both internal and external works. This can even include glazed products. This solution is also suitable for paint coatings, which are characterized by a high degree of strength and excellent adhesion. If you are faced with the task of using the adhesive composition on anhydride or gypsum substrates, as well as lightweight cellular concrete, whose age starts from 1 month, then the recommended addition to the composition in the form of an elasticizer is an indispensable solution.

The nuances of the work

If you will use “Ceresit SM 11”, technical characteristics, the price of which is indicated in the article, it is important to take into account the moment that the consumption of the composition will depend on the depth of the teeth of the tool used for applying the mixture. Before mixing it is necessary to warm the water to 35 degrees. When mixing, it is recommended to use a special construction mixer, which will achieve a homogeneous consistency. You can use a grater or putty knife during work, depending on what is more convenient for you.

Conclusion

It is important to exclude the possibility of overpayment for the adhesive. That is why before buying it is recommended to calculate the approximate amount that will be needed for the finishing work. For a 25-pound bag you will have to pay 250 rubles. In order to ensure even more economical consumption, the surface should be carefully prepared. It should ideally be as even as possible. Carrying out such manipulations will cost less in comparison with the purchase of glue.
