Knauf Fliesen tile adhesive: features and benefits

Among the presented variety of tiles to choose the right material is difficult. Even more difficult to choose the right tile adhesive. It is best to give preference to quality products, since it will depend on it the health of the household and the durability of the entire lining.

One of the best binder compositions include a mixture of Knauf Fliesen. It has excellent adhesive properties, so that even heavy varieties of tiles can be glued with it.

Composition and properties

The basis of Knauf Fliesen tile glue is sand and cement, which acts as a binder. In addition, the mixture contains a number of specialized additives that increase the performance properties of the finished product.

Fliesen tile adhesive is available for sale as a dry mix in strong paper bags of 10 kg and 25 kg.

For this composition is characterized by some distinctive features.

  • Plastic. Elastic material is easy to use. Due to the high ductility of the solution is convenient to apply on an uneven rough substrate with grooves or protrusions.
  • Frost resistance Glue compositions can withstand up to 25 cycles of freezing and thawing without losing the technical characteristics and performance characteristics declared by the manufacturer.
  • Strength. Due to the high strength properties, glued tiles will keep on the basis of a long time even with intensive use.
  • Resistant to moisture. Due to this feature, glue can be used in rooms with high humidity.
  • Good adhesion of the solution, which is provided by the polymer additives.
  • Waterproofing of hygroscopic mineral bases.

Knauf Fliesen is easy to prepare, for his breeding does not require special skills and abilities. To properly prepare the solution, you must follow the instructions and follow the proportions and recommendations specified by the manufacturer on the package.


Before buying a dry compound, one should pay attention not only to its cost, but also to technical indicators.

The composition of Knauf Fliesen has the following technical parameters:

  • high adhesion to concrete foundations (more than 0.5 MPa);
  • exposure of sharp fluctuations in ambient temperatures (from -45 to +80 degrees);
  • fast setting and hardening time of the finished solution (dries within 2 days under optimal conditions);
  • economical mass consumption (from 2 to 2.5 kg per 1 m2, depending on the quality of the foundation preparation);
  • small coefficient of moisture absorption (does not exceed 3%).

After laying the material on the mortar, the position of the tile can be corrected within 10 minutes. Glue has excellent physical and mechanical properties: it does not "slip" and securely holds heavy finishing materials, even such as stone.

Application and consumption

Knauf Fliesen tile adhesive is versatile. It is allowed to use both indoors and for exterior decoration. The composition is able to withstand the harsh climatic conditions characteristic of Russia.

With the help of the solution such materials are fixed:

  • ceramic granite;
  • ceramic tile;
  • various types of opaque stones, tongue-and-groove tiles and other materials.

Dry mix suitable for almost every base. It can be made of concrete, cement, limestone, drywall and other materials. Also, the solution is allowed to be laid on the previously installed tile matte plates. Due to the fact that the adhesive is able to withstand temperature fluctuations, it can be used for arranging the floor with a heating system.

The consumption of the finished solution will depend directly on the variety of the notched trowel used in the work, the level of processing the base and the calibration of the selected tile.

With a maximum allowable layer thickness of 5 mm, the consumption per 1 m2 will be something like this:

  • for a tile with dimensions of 10x10 cm, no more than 1.8 kg of material will go away (when using a trowel with a teeth length of 4 mm);
  • lining 20x20 cm will require at least 2.3 kg of mortar (spatula with 6 mm teeth);
  • for a tile of 30x30 cm it can take up to 3 kg of the finished mass.

The mixture is consumed sparingly, due to which the purchase of Knauf Fliesen composition can be called a bargain.


Before work dry mix should be prepared. To do this, take 1.4 liters of water and 5 kg of material (for dilution of 1 bag, approximately 7 liters of water will be required).To prepare the solution, pour the mixture into a prepared container with a measured amount of liquid. After that, the components should be mixed using a construction mixer or a drill with a special nozzle. Knead the composition should be within 2 minutes. The finished mass is characterized by plasticity and uniformity.

After mixing, allow the mass to stand for 10 minutes.then mix again. The finished solution must be used within 3 hours (hereinafter, it will begin to lose its elasticity). Working time with the material may be reduced due to too high air temperature or in the presence of drafts. If the mixture thickens, you need to re-mix it with a mixer without adding liquid. An additional amount of water will lead to a deterioration of the technical characteristics of the solution.

Preparatory work

Knauf Fliesen solution should not be applied on unprepared bases. Before proceeding to the finishing works, it is necessary to clean the base from various contaminants, fatty spots, old exfoliating layers. You also need to wash off water-based paint. After all the manipulations, the base should dry well.Do not apply the composition to wet structures.

When working with a solution, it is important to ensure that the room temperature is between +5 and +15 degrees. If the composition is planned to be used for arranging underfloor heating, the heating system must be turned off within 24 hours.

If it is intended to apply the material to weakly absorbent substrates (for example, concrete), they must be pre-treated with a primer. The primer is applied to the cleaned surface with a brush, roller or spray gun. If the base is characterized by increased moisture absorption (cellular concrete, porous brick), it must be coated with a primer at least two times.

Work should be done only after complete drying of the previous layers.

Application of the solution

The finished adhesive composition should be distributed evenly across the surface of the base, using the smooth side of the spatula. Then it is necessary to “comb through” the applied solution with the toothed side. It is necessary to cover with solution only that area which is possible to process within 20 minutes. During the street works and installation of the tile with the corrugated invoice the solution is applied both on a basis, and on finishing material.

After laying the first tile you need to lightly press it to the base. Within 10 minutes it is possible to adjust its position, because after this time the lining is securely engaged with the material.

Ceramic tiles are mounted using the “open joint” method. In this case, the plane must be leveled with the help of special construction equipment (level, level). When a dried crust is formed on the surface of the laid solution, the layer must be removed and the composition reapplied. If the glue accidentally gets on the lining, it must be immediately removed with a damp sponge or cloth, until it freezes.

It is important not to forget that the composition contains cement, because of which you need to observe some safety rules: you should work in protective gloves and avoid contact with the solution in the eyes. After the installation is complete, immediately rinse with water all the tools used.

Reinforced composition

Not so long ago, the manufacturer Knauf released reinforced adhesive for tiles Fliesen Plus. This is an improved modification of the mortar. It contains specific components that improve the technical parameters and performance properties of ordinary material.Such glue can be used at hard frosts and in conditions of high humidity.

It is suitable for installation:

  • natural and artificial stones;
  • decorative bricks;
  • mosaics.

Fliesen Plus can be used for both outdoor and indoor work. It possesses high adhesion and the minimum expense.


Knauf Fliesen tile adhesive is quite a popular product. It is preferred by both professional builders and home craftsmen who decide to do the repair themselves. Consumers emit the ease of preparation of the solution, its rapid setting and the fact that the finished mass does not spread. The product is in the middle price segment, so no one called it expensive.

Buyers also like the economical consumption of the finished mass. Of the shortcomings, consumers noted the inconvenient packaging and fast freezing of the solution, which is why all work needs to be done promptly, which is not always possible for people without relevant experience. Judging by the reviews, Knauf Fliesen tile adhesive fixes the lining reliably: according to consumers, even heavy stone finish continues to hold firmly on the base over time.
