Tile glue "Ceresit CM 11": technical specifications, instructions, reviews
After reviewing the diversity of the ceramics adhesives market, you will be able to understand that it is quite difficult to decide which composition is better to choose. Consumers do not know what to look for when buying. However, there are several key parameters that select the appropriate material. The cost should not play a particularly important role.
It is necessary to take into account not only the conditions and features of the flooring, but also the dimensions and materials of the selected tile. It is necessary to pay attention to the material of the surface that will be used for the work. As one of the defining parameters are the operating conditions. It is necessary to take into account air humidity, temperature range and surface load.
For example,for tiling open loggia will have to use frost and moisture-resistant compounds. The consumer should be aware that adhesive mixtures are divided into three groups. The first includes adhesives, the second includes improved cement mixtures, while the third includes specialized adhesives. Among others on the market today represented the brand "Ceresit CM 11", the technical characteristics of which you need to know before making a choice.
The above composition for laying ceramic tiles has among the ingredients polymeric additives, mineral fillers and cement. In order to obtain a ready solution, you should take 0.24 liters of water per 1 kg of the mixture. If you additionally plan to use an emulsion, then for 0.14 l of water you will need 0.08 l of an emulsion of the brand Ceresit CC 83.
It is important to bear in mind that “Ceresite SM 11”, the technical characteristics of which you can find out in the article, has a certain consumption time after preparation. Therefore, the composition of the shutter is necessary in such an amount that you will have time to work out within a couple of hours. In the open form, the mixture can remain for 20 minutes.You can change the position of the laid tile for another 10 minutes.
When applying it is important to adhere to a certain temperature of the base, which varies from +5 to +30 ° C. Sliding tiles from a vertical surface will not be greater than 0.5 mm. Work on the seams can be after a day. Before buying glue "Ceresit CM 11" technical characteristics it should be examined first. After reviewing them, you can find out that the solution has a certain level of adhesion to concrete substrates. If the operation is carried out in an air environment, the said parameter is 0.5 N / mm or more. When soaking in water, the parameter can be 0.7 N / mm. With alternate freezing and thawing, the adhesion of the mortar to the concrete base remains the same for 50 cycles.
It is important to take into account the temperature of operation, it varies from -50 to +70 ° C. Naturally, to know what the technical characteristics of such a composition as “Ceresite CM 11” is very important. But the manufacturer also mentions the tools that should be used to distribute the adhesive composition. For example, if a tile has a square shape with a side of 5 cm, then the tine should have a side equal to 3 mm. The consumption of the product at the same time will be kept within 2 kg / m2.
If the tile has a side of 10 cm, the size of the side of the tooth should be increased to 4 mm, while the product consumption will be equal to 2.6 kg / m2. With an increase in the size of the tile to 20 and 40 cm, the size of the side of the grater tooth should be 8 and 10 mm, respectively. At the same time, the material consumption under the above conditions will be equal to 5.2 and 6.5 kg / m2, respectively. When the tile size is increased to 40 x 40 mm, the tool prong should be equal to 12 mm. Glue will need more - up to 7.8 kg / m2.
"Ceresite CM 11", reviews of which it is recommended to read before buying a product, has special polymer additives. They, according to consumers, improve the technical characteristics of the product. Material frost and water resistant. He has, in the opinion of buyers, a variety of advantages, among them it should be highlighted:
- high adhesion;
- environmental safety;
- high level of moisture resistance;
- resistance to slipping tiles;
- convenience and ease of use.
Home masters emphasize that glue adheres well, even with absorbent and smooth surfaces. Even if during the work you plan to use a large tile, it will be firmly held on a vertical surface, without sliding down.Tile glue "Ceresite", according to users, is also popular for the reason that the composition is environmentally friendly. It is moisture resistant and easy to use.
Instructions for use
Before you start using glue, you need to prepare the base. It must be durable and dry and free from obvious damage. Before you begin to use the composition, the surface should be cleaned of sagging, dust and oil stains. It is necessary to remove other substances that would be able to reduce the adhesion of the mixture with products and surfaces.
Uneven areas need to be removed, and after alignment with the same mortar one day before the start of work. If the surface has irregularities greater than 20 mm, then they should be leveled with a solution that needs to be laid in two or more layers. When it is necessary to work with gypsum bases, they must be coated with a primer.
Often enough consumers ask how to dilute "Ceresite CM 11". You should know that the mixture is shut off with clean water, the temperature of which can vary from +15 to 20 ° C.For 1 kg of the composition will need about 0.24 liters of water. The resulting solution is mixed to a uniform consistency, which should not have lumps. Use for this should be low-speed drill with a nozzle. Some masters use a mixer.
The resulting material should be left for 5 minutes, and then mixed again. You can use it within 2 hours. Before using Ceresite CM 11, the instructions should be read. From it you can learn that the distribution of the composition is carried out in a thin layer using a grater, spatula or paddle. Application should be carried out on the surface to be veneered, and after the mixture is leveled with a float with teeth or a spatula.
Performance of work
The tile keeps within on the put mix and nestles. The maximum allowable layer under the tile should not be more than 10 mm. The tile is not presoaked. It is recommended to lay without seams. The distance between adjacent products should not be less than 2 mm.
Spacers are installed between the tiles for the same joint width. However, this process can be abandoned, because the tile does not slip. Under normal conditions,which are characterized by temperature within +20 ° C and relative humidity within 60%, the finish must be laid 20 minutes after applying the mixture.
If the work is performed outside the building in summer in windy weather, the installation should be completed in 15 minutes. The remnants of the mortar mixture are removed with water until it solidifies. Under normal conditions, jointing is performed after 24 hours. To fill the seams, you can use the materials of the Ceresite CE group.
Areas of use
Glue "Ceresite CM 11" is used when facing non-deformable surfaces with cement or ceramic tiles. Works can be carried out outside or inside buildings. An artificial stone can be used as a tile, its water absorption is 1% or less. In this case we are talking about internal work.
Glue "Ceresite CM 11" can be used for gluing tiles whose dimensions do not exceed 0.25 m2. In this case, we are talking about a square-shaped product with a side of 50 cm. As an alternative solution, there is a tile with dimensions equal to 60x40 cm
Laying surface can be vertical or horizontal.Lining during operation may periodically be subjected to moisture, in this case we are talking about:
Works can also be carried out in utility rooms, namely:
- in drying rooms;
Tile glue "Ceresite" can be used for laying tiles on the stairs, in the corridors, in living rooms and hallways. At the same time, work is underway on under-tick waterproofing. If it is planned to use a large-format tile with dimensions of 60 x 60 cm, then Ceresit CM 12 should be used. The composition is not suitable for marble and other light crystalline rocks that are prone to discoloration. Such products are stacked with the help of “Cerezite CM 115 (74, 79)”.
Additional recommendations for preparation
Having received the answer to the question of how much Ceresite CM 11 dries (this was discussed above), you can proceed to the surface preparation. It is important to clean the base where the tile will be laid, from materials that prevent adhesion, among them should be bitumen and grease. When concrete is used as a base, it is important to ensure that its age exceeds 3 months and the humidity is no higher than 4%.
Plasters and cement screeds, as well as cement-lime plaster age over 28 days can also be the basis for laying tiles. The humidity of the surface should not exceed 4%. Ceresite CM 11, the consumption per m2 of which was mentioned above, can be used inside buildings on gypsum and anhydrite surfaces; in the first case, the humidity should not be greater than 1% a, in the second - 0%. Such surfaces should be mechanically sanded and vacuumed.
Before choosing the adhesive composition for ceramics, it is especially important to pay attention to the technical characteristics of the tile itself. The composition for laying is also selected depending on the operational characteristics of the future coating. The mixture described above is good in that it is characterized by frost and moisture resistance, and tiles laid on vertical surfaces do not slip down.
