Recommended for porous ceramics that absorb moisture. Not suitable for porcelain stoneware slabs, since they have low water absorption and have a low-porous structure.

Flizen Plus with a reinforced formula

This composition has increased frost resistance. Indispensable for interior and exterior decoration using porcelain stoneware, ceramic tiles, natural stone. Not applicable for underfloor heating. For 1 sq.m. consumed from 1.7 to 2.2 kg (reduced consumption), depending on the type of surface, which must be leveled, dried and cleaned before laying. It differs from the universal Flizen by a large range of facing materials, since it allows you to work with low-porosity.

Flizen Flex

It differs from the universal Flisen in increased adhesion to concrete (1MPa) and elasticity, since it contains certain additives. Used for natural stone, porcelain stoneware, suitable for porous tiles. It is used for fixing expanded polystyrene, mineral wool, and other insulating materials.

Flisen Flex is recommended for surfaces with severe stress or temperature fluctuations. Suitable for industrial enterprises, as well as balconies, terraces, heated floors. It has proven itself well when used on wood and chipboard. Thanks to the increased adhesion, it is possible to lay the tiles on top of other tiles.

Flizen Marble

Fast-hardening adhesive containing cement, mineral filler, polymer additives. The life of the prepared mixture is 45 minutes. It has a white tint, which allows it to be used for glass tiles, translucent ceramics, glass mosaics. The color of the glue protects the facing material from discoloration. Also suitable for cladding granite, marble and other stone slabs.

Flisen Marble is suitable for both exterior and interior decoration of all standard flat substrates. It is used for balconies, terraces, underfloor heating and other surfaces subject to temperature fluctuations. It is used for laying tiles on floors with a high load, in this case it is applied to the tiles as well.

• Waterproof.
• For fastening heavy materials that are under constant mechanical and physical stress.
• Basis: concrete, brick, stone, old tiles.

The negative side is a long drying period. To achieve maximum performance, you must wait at least a week. Before application, it is required to level the plane and ensure its strength.

Usage

Tiled glue "Knauf Flizen" is applied to a previously prepared surface. To do this, it is leveled to such an extent that the drops are less than 0.5 cm.This can be done with plasters or with the glue itself.

The surface is cleaned, washed, dirt and dust are removed. The paint is removed. If it is impossible to do this (for example, waterproof paint), they sand it. After that, a primer is applied. To protect against moisture, a waterproofing solution is used (if water gets on the surface or gypsum plaster is applied).

Mix the glue solution in a ratio of three parts of glue and one part of water. Leave for 10 minutes. After the time has elapsed, mix well. If the consistency seems unsuitable, add water or dry glue mixture. Stir.

Next, a thin layer of the resulting solution is applied to the prepared surface. Moreover, this must be done in a small area, which can be processed until the solution sets (10 minutes). To make the tile sit evenly, crosses are inserted into the seams. After the tiles have dried, the crosses are removed. Seams are filled with special compounds (joints).

General rules and application features

Each type of glue has its own composition and application features. True, there are general rules that must be followed when using any adhesive product. Before applying the adhesive, you need to prepare the base. The surface must be level, clean, dry and primed. The Forbo company produces leveling compounds and repair compounds, as well as universal, epoxy, blocking, dispersion primers.

Features of the use of different types of glue:

1. Dispersive. Stir the acrylic dispersion well before use. The adhesive is applied only to the substrate with a brush, roller or fine-toothed trowel. The glue dries up after 20 minutes, dries completely within 48-72 hours.
2. Polyurethane. Consists of glue and hardener. Both components are mixed before use. The substance is applied to the prepared substrate with a fine-toothed trowel. The coating must be laid within 60-100 minutes. The substance solidifies completely after 10 hours.
3. Based on polychloroprene. It is recommended to stir the adhesive before use. The substance is applied to the substrate and to the entire surface of the flooring substrate using a brush or spatula. The glue dries after 20-60 minutes, dries completely after 24 hours.
4. Polymer dispersion. It is advisable to stir the mass before use. The adhesive is applied to the substrate and to the bonding material with a brush or roller. The substance dries up within 20-60 minutes, dries up completely in a day. Can be used on heated floors.

The work on laying the coating on the base is carried out using a semi-moist composition. It takes about 60 minutes to glue the materials. This time should be enough for the work itself and the elimination of possible defects. The glue itself dries up within 1-3 days.

Application

The area of ​​application of tile adhesive produced by the German brand Knauf is wide. It is actively used by builders, including professionals, when cladding walls, floors and basements of buildings.

Correctly selected composition has good characteristics, ensuring a long service life of the finish without changing the appearance and properties. Knauf Mramor adhesive mixture is the ideal choice for all tasks.

Breeding

The preparation of the mixture for the installation of tiles is carried out at an acceptable temperature ranging from +5 to +25 degrees. The kneading is done strictly according to the technology: no more than 7 liters of water is used per 25 kg bag. The composition is mixed with intensive rotational movements using a mixer with an operating power of 800 watts.

First, some water is poured into a clean container. After that, tile glue is slowly poured and stirred constantly. Then, the rest of the water and the mixture is added, the solution is brought to an elastic uniform state, like a cream. At the end of kneading, he needs to be infused for 5 minutes. At this time, preparatory work begins.

Preparatory work

They consist in cleaning the surface from all kinds of dirt and dust. To increase adhesion, the substrate is covered with a layer of high penetration primer. At the end of drying, proceed to marking and applying the composition to the floor or wall.

Application of the solution

The solution is applied in two ways: on the surface of the wall or floor, and on the tiles. Having chosen the preferred one, get to work. This requires a spatula with a comb. The size of the tooth is selected based on the type of tile, its weight and the required thickness of the mounting layer.

If the tile has dimensions of 60x60 cm, then the layer thickness should be 10 mm. If the dimensions of the tile are 30x30 cm, then the layer thickness is 4 mm.

Main advantages

Clay Knauf has several undeniable advantages.

Plastic

Due to its plasticity, the composition can be used on surfaces with small defects, since it will evenly fill problem areas. In this case, it is not required to pre-soak the tiles in water. Knauf's elastic structure allows it not to collapse for a long time.

Frost resistance

High frost resistance allows Knauf to be used for outdoor work. When changing temperatures, the seam retains its characteristics, remains intact.

Strength

The glue does not slip from the surface, makes it possible to hold even heavy facing materials

At the same time, it is important during work and further operation to observe the temperature specified in the characteristics of the mixture.

Good adhesion of the mortar

Knauf glue has good adhesion to substrates. However, since Knauf hardens quickly, it cannot be applied at a time to large areas, since when laying facing materials on a glue that begins to dry out, the quality of the bond will be reduced.

Ease of use

Working with Knauf glue does not require special training. It is enough just to strictly follow the instructions written on the packaging. Thanks to the fluidity of the composition, its inherent self-leveling effect, gluing tiles to walls and floors is not difficult.

Precautionary measures

KN-2 mastic belongs to combustible (flammable) materials. Do not smoke or use spark-generating tools when handling this substance. It is forbidden to make a fire during repairs. When the adhesive catches fire, a fire extinguisher, sand, and asbestos cloth are used to extinguish the flame. It is prohibited to use water to extinguish a fire.

You need to work with mastic in a protective suit, respirator or mask, tarpaulin gloves. KH-2 is considered a toxic product. If the substance comes into contact with the skin, it must be carefully wiped off with cotton wool soaked in solvent, and then the area should be washed with warm water and soap. If glue gets into your eyes, wash your face with warm water and consult a doctor.

Repairs should be carried out in a well ventilated area. When working with an adhesive product, it is forbidden to inhale the vapors of this substance. The solvent, which is part of KH-2, completely evaporates after 3 hours. After the adhesive has completely dried, the room in which the repair was carried out must be well ventilated. Further stay in the room where KN-2 glue was used is absolutely safe.
