Knauf fliesen tile adhesive: characteristics, advantages and disadvantages

Specifications

Knauf Perlfix gypsum adhesive has excellent properties corresponding to the high quality of all the company's products. The increased service life, which is more than twenty years, is one of the consequences of this quality. The level of adhesion to concrete is 0.6 MPa. The presence of gypsum in the composition provides a higher compressive strength of 10.9 MPa, and 3.4 MPa with a bend. Thanks to the thirty-minute adhesion, it is possible to correct drywall sheets using a building level.

The mixture is available in packages weighing 15 and 30 kilograms, which is very convenient. It must be stored only in a dry place, since it contains gypsum. It is best to store the mixture on wood pallets to facilitate optimal airing of the bags. This is also done to prevent the dry composition from becoming damp in conditions of high humidity. If the packaging is damaged, transfer the mixture to a whole bag and then put it back in the bag. The shelf life of an opened package is six months.

Knauf dry mix is ​​used on an ongoing basis in the construction and renovation of premises. According to its qualities, tile adhesive is suitable for working with different materials. The very first thing that comes to mind is a tile

In this case, it does not matter whether it is floor-standing, wall-mounted or ceiling-mounted. The tile can be not only ceramic - Knauf glue will easily work with a foam look, a clinker base or a tile

The adhesive mixture is ideal for drywall applications. And for filling the gaps between the sheets of gypsum board, Knauf Fugen putty is suitable. The basis of the putty is gypsum, so many people prefer to use it to glue the gypsum fiber (gypsum fiber) material to concrete. In addition, Knauf "Fugen" can be used for minor jobs, for example, small joints in plaster. In the assortment range of the Knauf manufacturer there is a tile adhesive "Marble". It is with him that the cladding of buildings is easily and simply made. The glue works harmoniously with materials such as granite, ceramic mosaic, glass.

It is worth paying attention to the fact that the manufacturer Knauf supplies dry mixes for various materials to the world market. So, in the company's catalog there is such a modern finishing material as aquapanels.

According to their characteristics, these are unique slabs. They optimally combine the following qualities: fire resistance, moisture resistance and, of course, frost resistance. The advantages do not end there: these plates do not rot, do not swell from moisture, do not deform. The advantages of aquapanels surpass many similar materials designed for wall cladding from the outside and from the inside.

A one-component polyurethane adhesive with the same name Knauf Aquapanel is used for gluing and sealing gaps. Available in 310 ml tubes. The use of this composition excludes the process of filling the joints between the plates, increases the reliability of the structures being erected. In addition, it is resistant to cracking and is an environmentally friendly material. But for working with tongue-and-groove plates (PGP), Knauf Perlfix assembly gypsum glue is used.

It is used exclusively for interior work. Its composition, after drying, provides an increased level of sound insulation. Another quality is that in the manufacturing process, ecological materials that are harmless to health are used.

Application and consumption

Knauf Fliesen tile adhesive is universal. It can be used both indoors and outdoors.The composition is able to withstand the harsh climatic conditions typical for Russia.

With the help of a solution, the following materials are fixed:

• porcelain stoneware;
• ceramic tile;
• various types of opaque stones, tongue-and-groove slabs and other materials.

A dry mix will work 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 previously installed matte tiles. Due to the fact that the glue is able to withstand temperature fluctuations, it can be used for arranging floors with a heating system.

With the maximum allowable layer thickness of the mixture of 5 mm, the consumption per 1 m2 will be approximately as follows:

• for tiles with dimensions of 10x10 cm, no more than 1.8 kg of material will be used (when using a spatula with a tooth length of 4 mm);
• for facing 20x20 cm, at least 2.3 kg of mortar will be required (spatula with 6 mm teeth);
• for tiles of 30x30 cm, up to 3 kg of the finished mass can go.

Breeding

Prepare a dry mixture before use. To do this, you need to take 1.4 liters of water and 5 kg of material (to dilute 1 bag, you will need about 7 liters of water). To prepare the solution, you need to pour the mixture into the 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 attachment. You need to knead the composition for 2 minutes. The finished mass is characterized by plasticity and uniformity.

After mixing, it is necessary to let the mass stand for 10 minutes, and then mix again. The ready-made solution must be used within 3 hours (then it will begin to lose its elasticity). Working time with material can be shortened due to too high air temperature or in the presence of drafts. If the mixture has thickened, you need to re-mix it with a mixer without adding liquid. Additional water will degrade the performance of the solution.

Preparatory work

Knauf Fliesen mortar must not be applied to unprepared substrates. Before starting finishing work, it is necessary to clean the base from various dirt, grease stains, old peeling layers. You also need to rinse off the water-based paint. After all the manipulations, the base should dry well. It is not allowed to apply the composition to wet structures.

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

If it is intended to apply the material to low-absorbent substrates (eg 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 (aerated concrete, porous brick), it must be primed at least twice.

Application of the solution

The ready-made adhesive composition must be distributed evenly over the surface of the base, using the smooth side of the trowel. Then you should "comb" the applied solution with the serrated side. Only the area that can be treated within 20 minutes should be covered with the solution. When working outdoors and installing tiles with a corrugated texture, the solution is applied both to the base and to the finishing material.

After laying the first tile, you need to lightly press it down to the base. Within 10 minutes, it is possible to correct its position, since after this time the cladding reliably adheres to the material.

Ceramic tiles are installed using the "open seam" method. In this case, the plane must be leveled using special construction equipment (level, level). If a dried crust forms on the surface of the laid solution, the layer must be removed and the composition must be reapplied.If glue accidentally gets on the cladding, it must be immediately removed with a damp sponge or rag until it hardens.

It is important not to forget that the composition contains cement, which is why you need to follow some safety rules: you should work in protective gloves and do not let the solution get into your eyes. After the installation is completed, immediately rinse all the tools used with water.

Specifications

Knauf products are used for both internal and external finishing works. Various mineral elements are used in its manufacture. With the help of them, additional useful properties are given to the glue.

Among the characteristics of the products, several main qualities can be distinguished.

Low substance consumption. It is no more than 2-2.9 kg / m2. The material is offered in various packaging, the most popular is 25 kg packaging, which is used for renovating large rooms.

• High level of tightness. It provides good adhesion of individual parts to each other.
• Freezes quickly. The glue dries in just 20-48 hours.
• Resistant to temperature fluctuations. The base can withstand temperatures from -50 ° C to + 80 ° C.

How to glue drywall on Perlfix

Preliminary surface preparation is indispensable. This stage is mandatory for any finishing work. They start by cleaning the walls from all types of possible dirt, if old finishing material is present on them, then it should be carefully removed. The next step is priming the surface, choosing compositions suitable for use under the glue.

Knauf primers are produced in plastic buckets; these are ready-made solutions that do not require preliminary preparation. Application is possible with a roller or with a brush. Before using Perlfix glue, wait until the primer layer is completely dry.

Before using Perlfix glue, wait until the primer layer is completely dry.

You need to dilute the mixture according to the instructions from the manufacturer. The consistency should be a paste. Add 15-16 liters of cold water to a 30-kg bag. First, the required amount of water is collected in the container, then the powder is poured into it, mixing is carried out, it is advisable to use a construction mixer for this purpose. Stir until a pasty mass is obtained. At the same time, make sure that there are no lumps left. Apply the resulting paste to the wall, for this use a notched rubber trowel. The distribution is uniform, leaving an interval of 3-4 centimeters.

After application is done in the center of the drywall sheet. You can make a checkerboard distribution, the layer thickness should be 2 centimeters. If the size of the panels is large, then you will need to apply the paste in two layers. You also need to apply the composition around the perimeter.

The gypsum plasterboard must be firmly attached to the surface. There are 10 minutes left to align the position, so you need to try to do the work quickly. Further, according to the same principle, they work with the rest of the material. The surface will have to dry for seven days, at which time no other work with the sheets should be carried out, so as not to violate the strength of fixation.

If the size of the panels is large, then you will need to apply the paste in two layers.

Features of use, tips and tricks

General guidelines for working with Perlfix glue have been described previously, but repairs may vary. With glue, you can glue not only drywall, but also blocks, polystyrene, gypsum board and more. Each type may have its own characteristics that should be taken into account during installation. Therefore, it is worthwhile to study the recommendations of specialists:

• After priming, while the wall is drying, check for dust and dirt on the surface. Their presence can lead to poorer adhesion;
• The container in which the composition will be prepared must be clean, it is better to rinse it in hot water. And the dilution of the glue is permissible, only cold.Moreover, the lower the temperature, the better, cold water helps to increase the use time of the ready-made solution;
• The application of the paste is made pointwise, in the form of flat cakes. They start from the center of the block, moving to the edges, the entire perimeter should be filled with glue;
• Tongue plates require the preparation of a more liquid solution, this will serve to reduce the remains of Perlfix glue in the joint zones;
• Excess paste that has been removed cannot be returned to the total mass, they will reduce the quality of the entire solution. Thickening will be faster;
• Working with gypsum board, you can apply the composition with a notched trowel along the length of the sheet, you can also work with a wall. The thickness is done by centimeter on the wall and panels. This technique allows you to get an even distribution, when the plate is applied to the wall, the glue is evenly distributed over all the gaps;
• When buying Knauf products, you need to demand quality certificates from the seller, it has become popular to create fakes of this brand;
• Temperature indicators in the room where the repair is being carried out are recommended to be done from +20 to +25 degrees.

With glue, you can glue not only drywall, but also blocks, polystyrene, gypsum board and more.

Types and forms of release

Knauf adhesives differ in the thickness of the layer and the caliber of the facing material with which they work. All types are packed in durable paper bags with several protective layers of 10, 25 kg.

Universal adhesive

Knauf Fliesenkleber is a universal composition for interior tile gluing with water absorption up to 3%. It is allowed to be used for external cladding, while the water absorption rate of the tile must be higher than 5%.

Fliesenkleber adheres well to concrete, plaster, cement-sandy substrates and drywall.

Flizen Flex

Knauf Fliesen Flex tile adhesive has increased elasticity and plasticity. Effective when working with porous, medium-porous tiles, stone blocks and porcelain stoneware. Adheres well to all substrates, including insulating materials. Knauf Flex can withstand a significant dynamic load. They are faced with surfaces made of wood, chipboard, heated floors are installed.

Flizen Plus (reinforced)

Knauf Fliesen Plus is supplemented with mineral fillers and polymers that enhance the strength of the joint. It has good adhesion to concrete and cement substrates, tiles are glued to drywall.

The reinforced composition is not afraid of low temperatures, therefore it is used in finishing work on the facades and basements of buildings. It glues materials with low water absorption, including not only tiles, but also various types of stone.

Varieties

Almost the entire range of gypsum glue on the market today is sold in the form of dry powder. It most often has a white color; it is rare to find a mixture of a grayish tint. Builders call this type the most successful. To increase the adhesive properties (adhesion of surfaces of different composition) to the main ingredient of gypsum, manufacturers add special elements, which, meanwhile, allow working with the glue not in emergency conditions. Another option for such families is an adhesive with quartz. The latter is added to reduce the material requirement of production. Eminent manufacturers have very little or no such ingredient.

The characteristics of the gypsum adhesive can vary depending on the amount of additives present. The main function of the glue is to help in the installation of various structures, to ensure the most durable adhesion of the working mixture to the treated surface. Therefore, another version of the composition with an increased amount of gypsum was released. The quality of adhesion and the volume of liquid that is used to dilute the factory powder are determined. The amount of water is usually indicated in the instructions on the package.

Advantages

Gypsum assembly glue has many advantages:

• It is easy and quick to prepare.
• When mixing, lumps are practically not formed.
• Installation of the frame is not required for installation.
• Differs in increased durability.

• Dries up relatively quickly.
• It is consumed sparingly, therefore, compared with conventional types of glue, which are inexpensive, the gypsum look pays off quickly enough.
• It is applied in a thin layer, therefore it saves space. In addition, this determines the previous advantage - material savings.
• Durability due to the addition of water-retaining additives to the composition.
• Cement mixtures require operational work, and the adhesive does not need to rush.
• It is possible to create the minimum thickness of the joint between the blocks / slabs for cladding. For example, the manufacturer of gypsum glue Knauf guarantees that the wall will not freeze.

Peculiarities

Today there are a large number of different building mixtures that allow you to glue different materials. Many under such mixtures mean only cement or special glue for tiles, but the number of compositions and their types is much larger. Gypsum glue deserves special attention.

It is most commonly used in the following situations:

• When installing GWP and GVL, where the glue acts as the main binder. These plates are large in size, with their help you can quickly erect partitions, so there is a need for glue that sets quickly. In this case, gypsum glue is the main competitor for polyurethane foam.
• For wall cladding with gypsum tiles and artificial stone. Basically, gypsum glue is used for interior work.
• When you need to glue drywall / gypsum fiber sheets to walls or ceilings in the form of a rough finish, gypsum glue is best suited.

Based on the scope of application of this binder, it is worth highlighting its main properties:

• hardens relatively quickly;
• affordable cost;
• characterized by good adhesion.

If we compare this type of glue with other types or cement, then disadvantages can also be identified:

• The structure of the mixture after curing is brittle, therefore it is not suitable for use under floor coverings.
• The glue is not moisture resistant and loses its properties upon contact with water, so it cannot be used for exterior decoration or in rooms with high humidity.

The glue is made relatively simple and fast. It consists of gypsum and various additives that increase the strength of the substance in question.

This type of glue is used mainly for large-scale repairs. This leads to the fact that many manufacturers pack this material in large bags of 30 kilograms. It is almost impossible to find small packages, however, there are also such.

Types of gypsum glue

Mostly the gypsum composition is produced in the form of a dry powder. The presented type of mixture is very convenient to use. To increase the adhesion properties, special substances are added to the main components of the composition, which, in addition to increasing the binding properties, allow you to work with the glue slowly.

It is added in order to reduce the cost of production of the material. Expensive types of glue either do not have this sand at all, or it is present in them in small quantities.

The main task of such a composition is to create a strong adhesion to the surface. On the building materials market, you can find gypsum glue, which contains a large amount of gypsum. This affects the adhesion of the binder to the surface. You can also determine the quality of this product by the amount of water required to prepare the glue. This amount can usually be read on the packaging.For example, if it is indicated that 300 ml of water is required for one kilogram of the composition, this indicates that a small amount of gypsum is present in the composition, due to which its adhesion properties are reduced. When purchasing such an adhesive material, you should be prepared for the fact that it may peel off during use.

Specifications

The main physical and mechanical characteristics of the dry mix are as follows:

• the life cycle of the finished solution is no more than 2.5 hours;
• adhesion to concrete - not less than 0.6 MPa;
• time for element correction - up to 10 minutes;
• the thickness of the adhesive layer is from 2 to 6 mm;
• grouting can be performed one day after the end of the installation;
• you can walk on the floor cladding after 24 hours;
• full weight load on the finished finish is possible after 7 days;
• working t of work is from +5 to +25 degrees;
• the composition is compatible with the "warm floor" system in the "Fliesen Plus" modification;
• frost resistance is at least 50 cycles;
• the shelf life should not exceed one year, provided the packaging is intact.

The brand's tile adhesive is quite elastic, which simplifies the cladding and the adjustment of individual elements. The composition dries on the floor quickly enough, while the glue is resistant to cracking.

Features and applications of glue

Mounting adhesive "Perlfix" is a dry mix on a gypsum base, including polymer additives that increase the level of adhesion to various substrates. This free-flowing mixture is intended directly for working with gypsum plasterboard (GKL), but is also suitable for cladding vertical surfaces with such building materials:

• Styrofoam;
• mineral wool;
• gypsum panels and blocks with a matte surface;
• expanded polystyrene;
• tongue-and-groove plates;
• insulating materials.

The composition provides reliable fixation of finishing materials even without the use of additional fasteners, and the manufacturer guarantees that it will not be damaged for several decades. The tool is very convenient to use: you just need to dilute it with water and apply it manually to the cladding sheets. The pasty mass does not flow, does not slip, ideally evenly distributed over the surface to be treated. Concrete, brick, various blocks can act as a basis.

There is a limitation in the use of Perlfix glue: it cannot be used in rooms with high humidity levels. Application is allowed only at normal and slightly high humidity, but subject to the exclusion of direct ingress of water

In the process of work, it is also important to pay attention to the quality of the preparation of the walls and finishing material. They must be completely dry, otherwise the reliability of the gluing will decrease.

Types and forms of release

On sale you can find two types of glue: standard and with the inclusion of gypsum fiber - "Perlfix" and "Perlfix GV", respectively. Both products are suitable only for interior work, their use outside buildings or in high humidity is unacceptable. Adhesives differ in the level of adhesion to drywall - in "Perlfix GV" it is slightly better, although both agents can be used on all the materials listed above. When buying, you should check the certificate of conformity so as not to buy a fake.

The adhesives are packaged in durable paper bags with internal protection of 15 kg and 30 kg. If the packaging is damaged, you will have to pour the dry building mixture into tight bags in order to completely exclude the access of moisture - otherwise, the gypsum in the composition may damp and deteriorate.

The composition of the glue

The basis, which ensures reliable fastening of drywall, is gypsum - a mineral substance from the sulfate class, environmentally friendly and completely safe to use. Due to the mineral base, the free-flowing mixture can have white, grayish and even pink colors, and in different batches of material, the shade can slightly change. The color of the mixture does not affect its technical characteristics and consumption per 1 m2.In addition to gypsum, the composition includes polymer additives that act as additional binders that reduce the porosity of the gypsum board and reinforce the surface.

Properties and characteristics

It is not necessary to add components other than ordinary water to dry glue; it does not require the introduction of hardeners or solvents. The finished solution has a slight moisture resistance, but it has a number of other positive properties:

• resistance to mechanical damaging factors;
• fast setting - in half an hour;
• the possibility of using for puttying, sealing joints between sheets of gypsum board;
• enhanced adhesion due to the introduction of special additives into the composition;
• long shelf life under the correct conditions;
• the possibility of using in unheated buildings;
• environmental friendliness of the composition.

Perlfix glue has a moderate cost - 350-380 rubles for a large package, which is also its advantage and allows you to reduce the overall repair costs. You can work with the product at temperatures of + 5 ... + 30 degrees, but it shows the best results at + 22 ... + 25 ° С. When the temperature drops to less than +5 degrees, glue detachment from finishing materials and walls is often observed.

The solution will have to be diluted in small portions - its viability is low (only 30 minutes). In order for the drywall fixation to be reliable, the layer must be sufficient - about 2 cm. The time for complete curing of the composition and the start of operation must be maintained, it is equal to 7 days. Only after its expiration, it is possible to give a full load to the treated surfaces. After the same period, it is allowed to grout the joints. The disadvantages include the short time for adjusting the position of finishing materials - up to 5-10 minutes, which may not be suitable for beginners.

Features of the glue

Perlfix assembly glue is a dry gypsum mixture with the addition of polymer substances that provide increased tenacity. This composition is environmentally friendly to health.

Specifications:

1. One bag contains 30 kg of the mixture.
2. The color of the dry mass can be different - white, gray, pink, but this does not affect the technical characteristics.
3. Consumption for gluing is 5 kg / m2 for installation of gypsum plasterboards, 1.5 kg / m2 - consumption for tongue-and-groove boards.
4. Dries up within 7 days.
5. You can store in unopened packaging no more than six months and strictly in a dry place.

Such a composition of the assembly mixture, which acts not only as a base, but also as an astringent, is made in compliance with all technological processes. The gypsum Knauf shown in the photo is ideal for gluing boards to an uneven, bumpy surface, which saves time and money for leveling the walls.

Description

Knauf Perlfix dry assembly mixture is made on the basis of gypsum with the addition of polymer additives. Gypsum glue has a number of advantages: speed and ease of use, high heat and sound insulation qualities, low labor intensity in application, environmentally friendly material (gypsum). Used only for interior work.

Knauf Perlfix mounting glue is used for gluing gypsum plasterboards, gypsum combined panels, tongue-and-groove, expanded polystyrene and mineral wool boards on various surfaces, including uneven and plastered ones. Work with gypsum assembly glue is carried out at a temperature not lower than +5 ° С.

The surface to be glued must be pre-cleaned of various contaminants: dust, bitumen, oils, grease, lime, adhesives, paints. A primer is required prior to working on poorly absorbent substrates such as in-situ concrete and concrete slabs.

The dry mixture is poured into a container with water at room temperature. For 30 kg of dry mix, 15-16 liters of water are needed. After that, the mixture is infused for about 2 minutes and stirred for 3-5 minutes. After obtaining a homogeneous consistency, the solution should be infused for 5 minutes, followed by repeated mixing.

Pot life of the finished material 30 min

Consumption of gypsum assembly glue 5 kg per 1 m2 of the treated surface

Consumption 5 kg / m2

Packing of goods: paper bag 30 kg. In undamaged packaging, the glue is stored for 6 months from the date of manufacture.

Manufacturers

There are a lot of companies that make gypsum assembly glue. We will consider the most famous of them, which are distinguished by good product quality:

Knauf

Makes gypsum glue in a package of 30 kilograms. The product from this manufacturer is the most popular product, as it is distinguished by good German workmanship.

The disadvantages of the product in question include only the following parameters:

• relatively high cost, due to the fact that these are branded products with an advanced manufacturing formula.
• unstable quality, which is due to the fact that the company has 10 factories that also deal with gypsum glue. Due to the difficulty of transportation, the product is delivered from the nearest factory, where the quality may be lower than in the central one. Some items have received negative customer reviews.

VOLMA

An excellent Volgograd company that manufactures a high-quality gypsum product using a unique technology. This manufacturer has an excellent reputation among builders. Many construction companies use Volma boards and mixes. As noted earlier, it is extremely difficult to find gypsum glue in small packages, however, the manufacturer in question produces packages of five and 10 kg. Despite the presence of such packaging, it is problematic to find them on store shelves, since builders do not need such a volume, and private traders rarely purchase such goods. The advantages of the gypsum composition from the Volma company are high quality and affordable cost.

Gypsum polymer

A company that cooperates with KNAUF. The German company manufactures for him the constituent components for creating gypsum glue. It should be noted that the German company wants to add Gipsopolimer to the list of subsidiaries, but the Perm manufacturer is still independent.

Comparing with the previous types of gypsum glue, it is important to note the relatively low cost, while the quality of the product does not suffer from this. It was the inexpensive price that became the main criterion for creating competition with previous brands.
