Putty KNAUF: characteristics, application

In the process of finishing measures, it is often necessary to finish the plasterboard surface, during which it is recommended to use putty. It is designed to eliminate defects on the surface, masking cracks and irregularities, as well as joints, holes from dowels and nails. However, modern construction technologies make it possible to significantly expand the possibilities of using putty, which can be used not only for the decoration of drywall walls and ceilings, but also to be the main component of many decorative objects: curly arches, domes and columns. Even inexperienced masters know that the quality of putty materials from the very beginning determines the result of finishing work. Moreover, the notorious fact is that plaster mixtures, in view of the large size of their particles, are not recommended to be used in the process of work with drywall surfaces. Experts advise replacing them with putty mixtures, the fine -fractional particles of which will more effectively fill all the irregularities available on the surface, and after drying contribute to the formation of a durable layer that prevents the surface cracking. The modern construction market does not cease to replenish the assortment of installation mixtures, and today the consumer has a fairly wide selection of these materials. In the process of finishing, it is important to correctly determine the manufacturer of the mixture, since putty mixtures of various brands are characterized by various composition, and, accordingly, in the process of finishing work, behave differently. This article will talk about KNAUF putty, which has high -quality composition and excellent characteristics that will achieve the desired result after completion of finishing work.

KNAUF company: Information about the manufacturer

KNAUF company is a family corporation founded in Germany at the beginning of the last century. The main specialization of the company was limited to the production of gypsum building mixtures and practically did not change for 80 years. Successfully functioning over the specified period of time, the corporation reached the global level and has established itself as one of the most successful companies engaged in the production of construction and finishing materials for both external and interior decoration. To date, products manufactured by the company are recognized as an undeniable leader in the market of finishing materials and is successfully used by masters around the world.

The main varieties of the putty of KNAUF: Brief description

The main purpose of putty mixtures is the finish of the surfaces made of drywall and other materials, which contributes to their mass use. In this regard, KNAUF offers an extensive range of goods of this group, which may vary in accordance with a number of specific features, such as:

• Compound;
• Purpose and scope of their use;
• The degree of readiness for use.

In accordance with the first sign, they distinguish:

• Gypsum puttycharacterized by low cost, ease of leveling and lack of shrinkage. The main, and perhaps their only drawback is their low moisture resistance, and therefore, they can only be used for internal work;
• Cement putty, compared with the first variety, are characterized by greater moisture resistance, as well as a significant degree of shrinkage;
• Polymer puttyThanks to their unique composition, they combine the advantages of the first two varieties and are characterized by high moisture resistance and low degree of shrinkage, and therefore, their use guarantees the high quality of the processed surface. Their only drawback is quite high cost due to the high cost of raw materials used in the production process.

The purpose and scope of use is another sign, in accordance with which you can classify KNAUF gypsum putty. The following varieties of such putty are distinguished:

• Aligning or starting puttycharacterized by high strength and maximum adhesion to all types of processed surfaces. A distinctive feature of the material is a granular structure, as a result of which it is used mainly to align the surface after its processing by plaster mixtures;

• Decorative or finish putty knauf, which is applied to the processed surface immediately in front of the decorative finish. Unlike the starting putty mixture Knauf, the putty Knauf Finish is characterized by less strength and considerable ease of application. The finished putty is designed to maximize all the available flaws, as a result of which, after its application, you will get a perfectly smooth and smooth surface. The optimal thickness of the applied layer of finish putty is 4 mm;

Important! Due to the fact that the finish putty are designed for finishing the surface, unlike starting putty mixtures, which are characterized by increased granularity, they are characterized by a more delicate, finely dispersed structure.

• Universal putty A variety of putty mixtures, combining the features of the previous two. In this regard, it is most advisable to use it only if there are no large flaws and damage on the surface to be treated. Given the fact that universal putty is characterized by higher properties, its price exceeds such for the two previous varieties.

By the degree of readiness for use, one can distinguish:

• Dry putty KNAUF For drywall surfaces, characterized by a longer shelf life (which can be realized only under certain climatic conditions) and lower cost. Despite the fact that factory packaging is with tightness, the manufacturer does not recommend storing a dry mixture in rooms with high humidity, as this can cause the mixture hardening. According to some masters, a lack of dry mixtures lies in the fact that in the process of working with them a large amount of dust and dirt is formed, but it can be considered very dubious, since in the process of taking the walls using a perforator, much more dirt is formed. The use of qualified specialists in the process of dry mixtures of the prerogative of qualified specialists, since in this case the effectiveness of the final result depends on the exact observance of the necessary proportions of the ingredients that are part of the working mixture;

Important!An indisputable disadvantage of dry putty, which significantly limits its use in the practice of builders, is the need for speedy use of the newly prepared working mixture, which, otherwise, will quickly lose its initial characteristics and will become unusable.

• Ready putty KNAUFUsing which, you will not face the need to prepare the working mixture, as well as the formation of a large amount of dirt and dust. However, unlike dry mixtures, the putty of Knauf Paste belongs to a higher price category, and are also characterized by a greater degree of shrinkage. With this in mind, when using ready -made mixtures, the thickness of the applied layer should not exceed 2 mm. Another feature of the finished putty that distinguishes it from dry mixtures is a shorter shelf life.

Putty Knauf Fugenfuller: General information about the material

The most striking representative of KNAUF products is the universal putty Knauf Fugenfuller, which is realized in the form of a dry granular mixture mixing well with water. Designed for internal finishing work, processing of seams and gypsum -plated surfaces, provided that the level of humidity is normal, putty Knauf Fugenfüller is based on gypsum, which includes specialized additives that retain moisture and slowing down the setting of the putty mixture.

Important! A few years ago, the manufacturer somewhat modified the name of the material, and it began to sound like a universal gypsum putty Knauf Fugen, and therefore, in the store you will not be able to find a putty with the previous name. If you still find such a mixture on sale, be vigilant, most likely you are faced with fake or very expired goods.

Universal putty KNAUF: Characteristics of the material

Despite the fact that the name of the material has undergone some changes, its composition remained the same, and therefore, the technical characteristics of the material also remained unchanged. The main advantages of putty are that, in view of the use of environmentally friendly materials in the process of its production, it is environmentally friendly, and is also characterized by the lack of shrinkage when solidified, during which cracks are not formed on its surface.

Consider the main technical characteristics of the universal putty KNAUF FEEN:

1. In the process of shallowing gypsum plastic joints, putting putty in two layers. In this case, the thickness of the applied layer should not exceed 1-3 mm;

2. The calculation of putty KNAUF puts down according to the following scheme:

• To seal drywall joints, on average, 0.25 kg of material per 1 sq. m surface. The calculation was made taking into account the need to close up with a working mixture of recesses formed from the use of self -tapping screws;
• To carry out continuous puttying of the plasterboard surface, provided that the putty layer is applied, the thickness of which does not exceed 1 mm, it is necessary to spend 0.8 kg of the working mixture per 1 sq. m;
• For finishing the previously plastered surface, it is necessary to use from 0.8 to 1.2 kg of putty per 1 square. m, while the level of consumption of the mixture is determined by the degree of surface roughness;
• To carry out the installation of grooves, purchase Knauf Fugen putty at the rate of 1.5 kg per 1 square. m;

3. The size of the fraction of the particles of the material does not exceed 0.15 mm;

4. Physical parameters:

bending strength 1.5 MPa;

compression strength is 3.0 MPa;

5. When using 1 kg of the mixture, the output of the solution is 1.3 l;

6. The time of use of the finished solution is 30 minutes;

7. Conducting work should be carried out at a temperature of at least +10 degrees;

8. The putty KNAUF, the price of which depends on the volume of the package, is produced in a container of 10 and 25 kg.

Varieties of putty knauf fugen

It is important to note that the line of Knauf Fugen is represented by three variations, each of which is characterized by its distinguishing features:

• Standard putty Knauf Fugen, for which all of the above characteristics are fair;
• Putty Knauf Fugen GV (Fugen GF), designed for the finishing of gypsum fiber sheets;
• Putty gypsum moisture -resistant Knauf Fugen Hydro, which is also used in the process of working with gypsum -fiber materials. Unlike previous putty compositions, hydrophobic additives are included in the structure of moisture -resistant putty, which provide increased moisture resistance of the material;

Important! The putty Knauf Furegen Hydro is in bags weighing 25 kg and has all the basic characteristics of the standard putty of Knauf Fugen. But taking into account its hydrophobicity and the degree of shrinkage, the permissible thickness of the applied layer can reach 5 mm.

As for the price of moisture -resistant putty, it is slightly higher than that for the standard putty mixture of Knauf Fugen.

The scope of use of putty Knauf Fugen: the most popular areas

The field of application of KNAUF is determined by its main component component with gypsum and its characteristics. Due to the fact that the construction mixtures based on gypsum absorb moisture, and are also susceptible to washing when water hits, the gypsum putty of Knauf Fugen cannot be used for external work. With this in mind, it is used only in residential premises with an optimal level of humidity. Using only in conditions of residential premises determines the composition of putty, which should include only environmentally friendly components and guarantee the absence of chemically active substances. All these requirements are complies with the putty of Knauf Fugen.

Let us consider in more detail the area of \u200b\u200buse of putty Knauf Fugen:

• Putty of drywall surfaces, as well as angles and joints;
• The decoration and manufacture of perforated reinforcing corners is also carried out using this material;
• Installation of grooves for the use of KNAUF putty;
• If it is necessary to gluing drywall sheets onto the flat surface, KNAUF putty is also used;
• If the seams are found between the slabs of concrete floors, they are sealed using the specified material;
• Putty of the plaster layer or concrete surface;
• Liquidation or, in case of it, in case of it, masking cracks between drywall sheets, groove slabs and concrete bases.

Advantages and disadvantages of putty knauf fugen

• A high degree of strength of the coating created using gypsum putty, which is especially true in the case of restoration work with drywall surfaces or the installation of protective corners;
• If you work with an even base, the manufacturer guarantees a low consumption of a putty work mixture;
• Using KNAUF putty, you can be sure of the high quality of the created coating, which is suitable for both wallpaper and painting for pasting;
• A wide selection of packaging options and affordable cost of the material.

Disadvantages of putty Knauf Fugen:

• High speed of solidification of the material, which is a very controversial disadvantage, which in some cases may turn out to be the advantage of the material;
• In the process of grinding the surface treated with putty Knauf Fugen, you may encounter certain difficulties. Even using the abrasive mesh No. 100, you will have to make considerable efforts;
• The impossibility of high -quality application of a layer, the thickness of which exceeds 3 mm;
• If you plan to glue the surface treated with putty, with light insufficiently dense wallpaper, you may encounter dark gaps on the wall.

Putty Knauf Rotband: General information about the material

The putty Knauf Rotband is also a putty based on gypsum, which is used for internal work. This material, manufactured in the form of a dry mixture, is implemented in hermetic packages of dense multi -layer paper, accompanied by detailed instructions for the use of the material. The basis of the putty of Knauf Rotband is the natural components obtained from gypsum stone.

Important! The gypsum stone is a very common material of natural origin, characterized by a porous structure, thanks to which it absorbs excessive moisture from the air.

Advantages of putty Knauf Rotband

• This material is environmentally friendly and does not distinguish harmful fumes during the operation;
• The acidity of this material is determined by production technology and never goes beyond the boundaries of permissible norms, approximately corresponding to the acidity of human skin;
• In the event of moisture from the putty layer, it does not slide and retains its original strength;
• Depending on the temperature of the room, the putty period of putty is no more than 5 days, and the average layer of putty 1 mm thick is freezing for 1-2 days;
• High fire resistance is another advantage of putty KNAUF ROTBAND. It fully meets all the requirements for fire safety of the material;
• The specified variety of putty is characterized by high thermal insulation characteristics.

Shpaklevka Knauf Uniflot: General information about the material

The putty KNAUF Uniflot is a composition designed specifically for the location of the seams and joints of drywall surfaces and panels made of drywall. A distinctive feature of this composition is the lack of the need to use a reinforcing tape when sealing the seams. Like any other Knauf putty, uniflot is a dry mixture based on gypsum modified by specialized additives. The main advantages of this material are increased strength and elasticity of putty, as well as high adhesive characteristics, due to which a powerful adhesion of the putty mixture with the processed surface is created, which guarantees the duration of its operation.

Methodology for working with putty Knauf Uniflot

Before starting work, a dry mixture of Knauf Uniflot is kneaded as follows:

• They prepare a container with water and gradually fall asleep into it a dry mixture at the rate of 1: 2, constantly stirring it with a mixer working at high speed, until a thick homogeneous mixture is formed. Knighting can also be carried out manually, however, the use of a mixer with specialized nozzles will significantly accelerate this process, and also guarantees the receipt of a better and homogeneous mixture. The prepared mixture must be used within an hour, after which it will begin to harden and become unsuitable for use.
• In most cases, a wide and narrow stainless steel spatula is used to apply putty in most cases. After you have completed work on applying putty, do not touch the surface just processed and do not try to remove or correct something. To eliminate the existing marriage, wait for the final drying of the surface and do it using sandpaper.

Important! Work using the putty KNAUF Uniflot can be carried out at a temperature of at least +10 degrees. At the same time, its consumption will not exceed 250 g per 1 sq. m processed surface. The price of putty from this manufacturer is practically no different from similar materials produced by competing firms.

Basic rules for working with gypsum putty: what does the home master need to know?

• Work with this material is not recommended to be carried out at a temperature below +10 degrees;
• Before direct operation with putty, it is necessary to thoroughly primed the surface;
• The mixture is diluted with clean water at room temperature, while the mixture must be poured into the water, and not vice versa, and mix thoroughly. Then she is allowed to stand and mix again. The manufacturer advises using a narrow spatula, but the use of a mixer will significantly accelerate the process of preparing the mixture;
• After each kneading, it is necessary to thoroughly rinse all the used tools, since the frozen particles remaining on their surface significantly accelerate the solidification of the working mixture;
• To seal drywall seams using gypsum putty, it is necessary to use a reinforcing grid. In this case, the second layer of putty is applied after the first dries.
