Application area

Knauf is a German company that makes Glue Flizen. This is a loose construction mix that, when diluted, becomes a tile-laying, porcelain tile, clinker, tile block, and mosaic solution.

Although the composition works well with any type of tile, the following materials work best with it:

• Tiles 300×300 mm with moisture absorption of more than 3%;
• porcelain stoneware 600×600 mm;
• Any floor porcelain.

When attaching bases made of polystyrene, foam, glass wool, and polyurethane during the installation of fiberglass sheets, KNAUF’s glue has shown to work well. They glue the finishing and insulating material to concrete, cement, silicate surfaces, brickwork, and drywall because of their high adhesion parameters. Grooves are glued together using fliesen.

The adhesive composition is used when laying warm floors and other heating-related structures because of its resistance to temperature changes. To glue the internal and external cladding together, use lizen.

Compound

The connecting element in Fliesen, which has a cement base, is a tiny amount of sand that gives the powder a gray hue.

Polymers, additives, antiseptic, and fungicidal additives are combined into powder to guarantee quality attributes.

The mixture works well for joining porous and relatively even materials.

Selecting an alternative Knauf remedy is preferable if the material has poor moisture absorption.

Properties

• A thick consistency of the mixture allows you to fix heavy slabs, blocks, elements made of stone. To ensure good adhesion, you need to accurately comply with the instructions and do not violate the temperature regime during operation.
• Knauf Flezen has a short period of adjustment, so it must be applied to small surface. If you glue the tiles on the dried solution, the adhesion characteristics will be significantly reduced.
• Glue is elastic, it is easy for them to process surfaces with small defects and pits. Thanks to the plastic structure, the glue seam is not destroyed over time. Suitable for use on terraces, street steps, balconies and verandas.
• Glue is resistant to dampness, so it can be used to lay cladding in the kitchen, bathrooms, dressing rooms, etc.D. Waterproofing of moisture absorbing grounds on a mineral basis is performed, and protection against mold, microbes, and fungi is additionally ensured.

Even someone with no prior construction experience can prepare a solution if they follow all of the package’s instructions. In order to ensure that the final solution has an adequate degree of adhesion, the manufacturer’s recommended proportions are strictly adhered to.

Advantages

• Used on various grounds, well compiled with insulating materials.
• Tiles of different types are glued, mosaic. Due to gray coloring is not recommended for transparent or glass cladding.
• The non -professionals can work with the composition, for preparation, it is quite accurately to fulfill all the points of the instructions.
• Low fluidity allows you to use a fliz for gluing cladding on vertical structures.
• The mixture evens out the surface with a drop in heights up to 0.2 cm, so that the number of repair work is significantly reduced.
• Forms a monolithic surface, adjusting it, hiding the microcracks in the screed.
• The adhesive seam has a long service life, the tile will stay for a long time on any surfaces in heated, unheated rooms and on the street.
• The seam does not affect the intense, dynamic load, it does not deteriorate, does not collapse.
• The finished mixture is very plastic, because of which it is not necessary to soak the tiles before gluing.
• Sold in comfortable packaging. Packing in packs of 25 kg. The price is available unlike analogues of other manufacturers.

Flaws

• If you do not prepare the base before gluing or disrupt the temperature mode of operation with the composition, then its adhesion worsens.

• Glue has a fairly short correction time. It is sometimes difficult for beginners in 10 minutes. install the clarification coating correctly and at the same time use the entire prepared composition.

Types and forms of release

The Knauf adhesives vary in the quality of the facing material they work with as well as the layer thickness. Each type weighs 10, 25 kg and is packaged in sturdy paper bags with multiple layers of protection.

Storing packages is recommended on wooden pallets in rooms protected from moisture.

Universal glue

A versatile composition for internal work on gluing tiles with up to 3% water absorption is Knauf Flezen Cleber. It is acceptable for use as external cladding as long as the tile’s water absorption indicator is greater than 5%.

With plastered, cement-sand bases, drywall, and concrete, Flizenkleber is more than suitable.

Low porous tiles, which have a low coefficient of water absorption, are not glued with it.

Flizen Flex

Tile glue with higher elasticity and plasticity is Knauf FLiesen FLEX. efficient when working with porcelain tiles, stone dies, and porous or medium-porous tiles. It sticks well to everything, even insulating materials. Knauf Flex can sustain a large dynamic load. Warm floor mount, chipboard, and wood surfaces face them.

Flizen plus (reinforced)

Mineral fillers and polymers are added to Knauf Fliesen Plus’s composition to improve the seam’s strength. The cement bases and concrete combine well, and the tiles on the drywall are adhered to.

Because the reinforced composition is not affected by low temperatures, it is utilized to complete building basement and facade construction. Low water absorption materials, such as tiles and different kinds of stone, are used to glue them together.

Flizen marble

Knauf Marble is white because it is made of minerals, polymers, and a white sequence. They are able to glue mosaics, ceramics, glass tiles, granite, artificial and natural stone, and porcelain stoneware. possesses a high adhesiveness. Marble is placed on the incorrect side of the material and on the base when adhering large-sized Fliesen elements.

Comparison with other analogues of the line

The compositional additives used in KNAUF tile adhesives vary. They are in charge of glue’s characteristics and function.

• For the installation of the warm floor, only those mixtures that are not afraid of the temperature difference, for example, Flizen Flex are used. It is optimal when laying industrial floors and surfaces subject to dynamic loads.
• KNAUF universal Flezen is rarely glued with porcelain tiles, more often it is used in the installation of ordinary tiles.
• Fliesen marble is used when working with decorative or artistic tiles.
• KNAUF Flezen Max is applied with a layer of up to 3 cm, it helps to enhance the strength of the masonry, levels the floor, walls, is used on surfaces with large height drops, but They cannot be attached to the cladding on the warm floor.
• The composition of the flisen plus is glued low -porous cerm border tiles.

An equivalent product from other manufacturers is Ceresit SM-11 tile glue.

Consumption

Tile size, cm	The height of the spatula bean, cm	Tile glue consumption for 1 m2, kg/m. sq.
Less than 10	0.4	1.7
10-20	0.6	2.2
More than 20	0.8	2.9

When the tile’s back is smooth, the size of the spatula tooth is listed in the table. The tool’s teeth should be higher if the tile is relief.

Utilization of various brands:

• Flizen-2.2-2.9 kg/m. sq.;
• Flizen plus-1.7-2.7 kg/m. sq.

The following formula is used to determine the quantity of bags: N = (s*l*h)/2,

• where n is the number of bags;
• S is the area of ​​the pasted surface;

• L is the height of the spatula tooth;
• H – basic material consumption.

Assume that a 20 m³ room has tiles installed on its floor. In this scenario, the mixture’s basic consumption is 2.2 kg/m³. The spatula teeth measure 0.6 cm in height, and glue comes in 25 kg bags.

(20*2.2*6)/2 = 132 kg, or roughly six dry glue bags.

Breeding the mixture

Water and dry powder are combined precisely by volume. Add 250–300 ml of water to 1 kg of loose mixture. To make a 25 kg paper bag, 7–7.5 liters of water are needed.

Using a construction mixer or a drill with a nozzle, the powder is added to the container along with water, and the mixture is thoroughly mixed. The solution in the container needs to be worked until it is homogenous and lump-free. A lid is then placed over the container. Following a five-minute break, the mixture is combined once more and is entirely operational.

For 2.5 hours, the prepared solution retains its properties. You must have enough time during this period to develop the entire volume before moving on to the next batch.

It is not advised to breed water in the mass, but it can be combined with a mixer if it has slightly thickened.

Necessary tools

• Tough a spatula with a correctly selected height and the shape of the teeth.
• Master OK.
• Leveling, level.

Surface preparation

It is verified that the environment’s ambient temperature matches the ideal temperature regime as specified in the instructions. The glue dries quickly in hot weather and thoroughs or freezes at temperatures below +5 °C.

1. The basis is cleaned of dust and pollution.
2. Formwork lubrication is tapped from the concrete surface.
3. The base is degraded by household chemicals or solvents.
4. The old finish is removed.
5. Water -based or any unstable to water, the paint is washed off, waterproof paint and varnish materials are cleaned with a skin.
6. The surface is dried, the wet bases cannot be covered with a mixture for tiles.
7. When arranging the warm floor, it is disconnected from power a day before the start of preparatory work.
8. Gypsum screed and areas subject to water are covered with waterproofing.
9. If the thickness of the plaster on the basis exceeds 1 cm, the excess is eliminated.
10. Silovovic bases are primed. It is better to use the soil of the same manufacturer.

KNAUF Grunderitel is for extremely porous surfaces; Knauf Tiefengrund is for moderately porous surfaces.

Knauf Fliesen tile adhesive is a well-liked option for tile projects because of its strong bonding power, simplicity of use, and suitability for a range of tile kinds. Excellent adherence ensures that tiles remain firmly in place, and its flexible formula helps to prevent cracking by accommodating small movements. It is important for users to be aware of the setting time, as it might necessitate meticulous planning during installation. All things considered, Knauf Fliesen glue is a dependable choice that strikes a balance between usefulness and ease of use, though application requires accuracy to get the most out of it.

Application of glue

Using a trowel, the completed mixture is removed from the tank. Transferring the glue to the spatula’s smooth side, it is spread uniformly at the base.

The tool’s gear portion is then assembled in accordance with the layer of adhesive that has been applied. Ideally, the glue should make up 80% of the base for a good coupling. The process for calculating the number of composition is as follows: after the glued tile is taken off, the master looks at the other side and gauges how much glue is still on it. Should there be insufficient mixture, you must swap out the spatula for a larger-toothed instrument. Additionally, glue can be applied to the facing material’s interior.

KNAUF Flezen is applied to the base and the incorrect side of the tiles when performing exterior work.

Its location can be adjusted for an additional ten minutes after the tiles are adhered. When it is properly laid, he presses boldly toward the base to improve fixation. A level or leveling controls how even the styling is. A new layer is applied in its place after a dense film is manually removed from the applied solution. Using a moist cloth, the composition that has fallen on the tile’s front can be easily removed.

Plastic crosses or clamps are used, and they are taken out after a day, to ensure that the spaces between the tiles are uniform. A grouting mass is used to fill the spaces between the stacked tiles, and once it has dried, the grout’s remnants are scrubbed with a dry sponge. Only after the tile glue has fully set can grout be added.

Recommendations

• With an increase in the ambient temperature, the time of working with the mixture decreases.
• During work, you cannot allow drafts and direct sunlight.
• In wet rooms, the working hours with the composition are increasing.
• You can not dilute the mixture with any liquids, except for water.

• For external work or when gluing large areas, it is recommended to provide deformation seams.
• After work, the entire tool is washed with water even before the solution is hardened.
• All work with tile glue is carried out in protective equipment.
