Technical characteristics of perlfix glue. Mounting adhesive Perlfix - overview and application

Carrying out repair work involves the use of a sufficiently large number of mounting components. Usually nails are used, but they are not always best solution for surfaces such as drywall. This material is very thin, and nail holes can damage it. Professional craftsmen recommend using a special mounting adhesive, which will be beneficial both from a practical and economic point of view.

One of the best in this niche is glue for drywall Knauf Perlfix is a great alternative to nails and screws.

Peculiarities

Knauf was founded in the middle of the last century. small firm quickly developed into a huge manufacturing concern building materials thanks to the responsibility of the owners and careful quality control at every stage of the production of products. Today Knauf are one of the leaders in their niche, their products are presented all over the world.

Perlfix glue is one of the most purchased products. The main objective of the product is a frameless surface coating sheet materials on the plaster base. There are only two types of adhesives that differ from each other both in ingredients and in the level of adhesion to the surface: ordinary Perlfix and Perfix GV.

A simple mixture is made to cover the bases with drywall, and with additional gypsum fiber - for GVL.

The material of the coating itself is not very important, since this mixture is perfectly combined not only with gypsum, but also with concrete and brick, it is only important to choose the right soil. For example, in order to glue drywall to a concrete base, you should take a concrete contact, if there is a gypsum or lime plaster, you can take a simple mixture of deep penetration. Knauf glue is also suitable for working with insulating materials, for example, expanded polystyrene with extrusion or minplitom.

You can only use Perlfix for internal work. The composition is perfectly applied in both warm and cool rooms, however, it should be remembered that the humidity level in the room should be above average. You can glue them not only drywall, but also matte gypsum tiles, polystyrene foam, mineral wool and polystyrene foam. Try to prevent any direct contact of water with the applied mixture. Do not use glue wet surfaces as this may damage adhesion.

Gypsum mortar is sold as a ready-to-apply dry product, so there is no need to use any additional ingredients.

In the case of repair work under special conditions, the company manufactures products that differ from the base adhesive. Their composition provides for application to non-standard surfaces.

Specifications

Gypsum adhesive Knauf Perlfix 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 setting level with concrete is 0.6 MPa. The presence of gypsum in the composition provides a higher compressive strength of 10.9 MPa, and with a bend of 3.4 MPa. Thanks to a thirty-minute setting, drywall sheets can be adjusted 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 gypsum is included in its composition. It is best to store the mixture on wooden pallets to promote optimal ventilation of the bags. This is also done to prevent dampening of the dry composition under conditions high humidity. In case of damage to the packaging, transfer the mixture to a single bag, and then put it back into the bag. The shelf life of an opened package is six months.

Advantages and disadvantages

Knauf Perlfix glue has both big amount pluses, and some minuses, which must be taken into account when buying. One of its main advantages is the ecological purity of the mixture, as well as the absence of a toxic odor, which makes it safe for health. When using glue repair work go much faster and easier. Due to the absence of the need to use a hammer or a hammer drill to drive nails and screws, your repair will be absolutely silent and economical, since you will not have to spend money on additional tools. The composition is applied with a special spatula of a ribbed shape, either immediately on the entire surface, or in cakes.

A big plus of this product is the versatility of use, it works great with different materials. Some craftsmen use it during non-essential putty work.

The huge advantage of Knauf is the availability of quality certificates for each of its products, which guarantees high quality of all goods, as well as careful control on different stages manufacturing.

However, the adhesive mixture has several disadvantages., one of which is long time drying, which is a week. This characteristic is associated with the components that make up the Knauf adhesive. After drying, the adhesive becomes very strong and provides a secure attachment to long years. During this process, that is, all seven days, the composition will increase the level of strength and, as it were, shrink the material. During this period, it is necessary to postpone any puttying work to prevent the appearance of cracks.

Another feature of Perlfix is the short time needed to correct GKL or GVL blocks.

It is only ten minutes, and sometimes five. Glue enough for short term loses plasticity, which is why any changes in the imposition of sheets, the elimination of bumps or pits that have appeared should occur in a short time. After ten minutes, all your efforts will be in vain, as the mixture will no longer stretch. Despite such a quick setting of the product, it will finally harden only after a week. The cost of this product is quite democratic and amounts to 300-350 rubles per bag.

How to use

Before you start working with Knauf Perlfix glue, you should determine its consumption for desired surface. According to the instructions, the consumption of the mounting compound for drywall is 5 kg per 1 m² when treating GKL and GVL surfaces, in the case of working with GWP, the consumption will be 1.5 kg per 1 m². However, in practice, the consumption of funds may be slightly different, it all depends on the experience of the master. Professionals who have already pretty much gained their hands on the installation of tongue-and-groove tiles (PGP) apply a little diluted glue to the surface so that after laying the sheet, a little money comes out of the joint. Beginners in the construction industry do not like to save the mixture, thinking that it is bad, and they apply a lot of glue, which leaves a large amount of excess composition.

Here one should take into account the fact that the work takes place with gypsum, and not with ordinary glue or cement. If in the second case it is possible to remove all excess with a spatula and put them back into the container, then in the first case it is impossible to do this, because the mixture collected from gypsum will greatly reduce the life of the glue. It will simply dry out right in the bucket in about fifteen minutes, which will entail an overrun. But thanks to its ease of use, you can quickly and easily learn how much to prepare the mixture and apply to the base to be treated.

The consumption of the mixture for GKL is more accurately calculated taking into account the irregularities or roughness of the base.

One of the main conditions when working with Perlfix glue is the level temperature regime, which should not be lower than +5 degrees. When working with a product weighing 30 kg, you will need 16 liters of water.

Work with Knauf Perlfix glue is carried out in the following order:

first you need to clean the wall from dirt, dust and detachments;
in the case of working with plasterboard, the wall should be primed, preferably with a primer of the same brand as the drywall adhesive itself;
to carry out the process of mixing the mixture, usually this is done in a plastic container;
a dry mixture is added to the water in a ratio of 1: 2;
it is recommended to stir with a construction mixer, as a result, a mixture without lumps should be obtained, similar in density to sour cream;

Mounting glue Perlfix is produced by the German company Knauf, founded by the brothers Alfons and Karl Knauf in pre-war Germany. They were fascinated by plaster and its unique properties. The company has grown rapidly in post-war years, and at first a plant for the production of dry building mixtures, and then the production of drywall. Currently, the Knauf company is the world leader in the building materials market, associated with the present German quality.

Among the many dry mixes produced by Knauf, its purpose and popularity among consumers has gained mounting adhesive Perlfix, designed for the installation of partitions and light walls made of PGP (grooved gypsum boards) and gluing drywall sheets. You can fix drywall different ways. Installation with Perlfix Knauf glue does not require the preliminary formation of a metal frame, drilling of walls and fastening metal structures. Many buyers prefer this way.

Knauf Mounting Glue Perlfix is a dry mix with increased adhesion (adhesion to the surface). The mixture consists of gypsum and polymer additives that improve its properties, while it is environmentally friendly, safe for human health.

Advantages of Mounting Glue Perlfix Knauf:

Ability to bond drywall tongue-and-groove slabs, combined, as well as insulation - mineral wool or polystyrene foam.
Does not require pre-installation of a metal frame.
Various substrates: concrete, brickwork, cement putties, plasters. The presence of irregularities and depressions on the surfaces is acceptable. They will be securely hidden by drywall sheets or other materials that Perlfix Knauf glues together.
Ease of mixing. Easily spreads without forming lumps.
Strength. The material is glued to the surface "tightly".
Dries quickly.
Profitability. Consumption is much lower than others adhesive compositions because a thin layer of adhesive on the surface is sufficient.
Durability. Perlfix contains water-retaining additives, thanks to which it retains its adhesive properties longer.
High viability of the composition, in contrast to cement mortars.
Minimum seam. Knauf guarantees non-freezing of surfaces through the masonry joint.

Application:

When preparing the surface, clean it of old fragments of putty or other mortars from dirt and dust.

A dry plastic container is being prepared in which the batch will be carried out. Water and glue are mixed in the proportions indicated on the product packaging (usually 1:2). The viability of the resulting mixture is 30 minutes.

Glue is applied to drywall sheet on middle line pointwise at a distance of 30cm-35cm. If the thickness of drywall is more than 10 mm, then the glue is applied around the perimeter in two rows. After that, press the sheet to the surface. Tapping with a mallet, they level him. While the glue has not hardened, the drywall sheet can be adjusted within 10 minutes.

If the solution is dry, then do not add water to it - Perlfix will lose its properties.

The modern building materials market is very diverse. One of the leaders in its segment is Perlfix drywall adhesive (KNAUF PerlFix). Let's look at its characteristics and features of the application in more detail.

Purpose, properties and characteristics of Perflix glue

Perlfix drywall adhesive is a gypsum-based dry mix with polymer additives that provide high adhesion during installation. With its help, you can glue all kinds of gypsum combined panels(GKP), drywall sheets (GKL), materials intended for heat and noise insulation of walls (slabs of mineral wool and expanded polystyrene) on an uneven surface of a brick, plastered, concrete, foam concrete base of the walls. Knauf drywall glue is not suitable low temperatures, therefore it is used exclusively for decoration internal surfaces rooms in which normal and elevated level humidity.

Knauf Perlfix drywall adhesive is available in paper packs of 15 and 30 kg.

Specifications glue for drywall Knauf Perlfix:

Advantages and disadvantages

Knauf Pearlfix drywall adhesive has a huge number of advantages in comparison with other similar products. One of the components of the popularity of this mixture is that it is easy to work with. Thanks to excellent qualities adhesive leveling of the surface of the walls is carried out quite quickly and does not require the installation of a supporting frame. Using Perlfix will help you save floor space when covering walls.

Another advantage of glue is its versatility. With it, you can perform small work on puttying the walls. It is lightweight and highly flexible. Perlfix is made from environmentally friendly materials that are not harmful to health. Also, the advantage of "Perlfix" is its price, this glue has an optimal price-quality ratio.

TO disadvantages of Knauf Perlfix can be attributed to the long time required for the adhesive to dry completely. For 7 days, it is not recommended to touch the lining planted on Perlfix. The problem lies in the composition of the adhesive, but when the drying time comes to an end and it hardens, a strong and reliable seam is formed.

How to work with him

Getting started with Perlfix, it is necessary to determine the scope of work, the area of the working surface and what material consumption will go to a given area. The unevenness of the walls of the room and the thickness of the application of the material will determine the consumption of Perlfix plasterboard adhesive.

Installation of drywall on "Perlfix" takes place in several steps:

Storage conditions

Storing Knauf drywall adhesive is easy, allowing you to use the rest of the material in the future. Knauf dry mix must be stored in bags on wooden pallets in dry rooms. The shelf life of intact or hermetically sealed bags is 6 months.

After reviewing the characteristics of Perlfix glue, we can conclude that the purchase of this mixture is a profitable solution that will save your time and budget.

Gypsum adhesive is typically used for gluing drywall, gypsum-based panels and decorative gypsum elements. What gypsum glue to choose, what indicators you should pay attention to, we will tell in this article.

Gypsum-based adhesive, as a rule, is available in the form of a dry powder - this is the most best view adhesive agent. Additives contribute to better adhesion and you can work with such glue slowly. You can often find quartz sand in the composition of the adhesive powder, it is added to reduce the cost of production. In more expensive adhesives quartz sand or little or none at all. Depending on the amount of such additives in the adhesive, its characteristics change. The main task of the adhesive is the strong adhesion of the material to the surface - this is called adhesion. And so it can be concluded that the adhesive must have a high adhesive degree. Increases the adhesion of the amount of gypsum, therefore, the greater the percentage of gypsum in the mixture, the greater the adhesion;
The adhesion of the adhesive is also determined by the amount of water that needs to be diluted with the powder. As a rule, the amount of water required is indicated on the packaging. If the package says that you need 300 ml of water per 1 kg of glue or less, you can safely say that there is little gypsum in the mixture, and a lot of filler. And this suggests the conclusion that the adhesive ability will be low, and the glued material will fall off, the only question is time. When choosing an adhesive, it is important to remember the ratio of water and gypsum than less water, the less gypsum and more additives;
Another important point is the setting time of the adhesive mixture. At good glue this period should be as short as possible. Depending on this indicator, the pace of work is determined, the time that must be maintained for gluing the material in a pressed state. Glue in the bucket is stored for one hour. But this does not mean at all that if applied to drywall, the shelf life of the glue will be the same. As a rule, this indicator is different for each manufacturer. In practice, we can say that the minimum time is about ½ hour, and the maximum is one hour and ten minutes.

Volma installation

Glue gypsum montage basically contains binder gypsum, and additives of modified and chemical impurities that increase adhesive properties. Another advantage of Volma mounting glue is its water-retaining property and optimal timing for work.

Application methods

Volma installation is used for partitions, which are constructed from tongue-and-groove gypsum boards. Gluing gypsum parts or decorations, mounting GKL and GVL, gluing thermal insulation on vertical surfaces. Used at temperatures from five to thirty degrees Celsius at optimal humidity air. Can be glued to concrete, plaster, gypsum products, brickwork, aerated concrete and foam blocks, GWP, drywall and gypsum fiber surfaces.

Main characteristics:

When constructing single partitions from PGP per 1 m 2, 1.5-2.0 kg of dry adhesive mixture is used;
When installing GKL or GVL per 1 m 2, they differ from the type of surface:
- On even grounds from 0.3-0.5 kg;
- On uneven surfaces with recesses up to 2 cm, the consumption of dry mix is from 3.5-5 kg;
- On uneven surfaces with recesses of more than 2 cm, consumption from 4-6 kg;
To prepare one kg of dry mix, 0.5-0.55 l of water is used;
The solution can be used within one hour;
Complete drying time - a day;
Gluing pressure not less than 0.6 MPa;
Adhesion with the surface is not less than 0.5 MPa;
The temperature of the working plane is from 5 to 30 degrees Celsius.

Knauf-Perlfix

Glue gypsum mounting Knauf is a powder. The main adhesive element of Knauf Perlfix is gypsum binder with additional elements. It is used for gluing GKL and GKP (mixed gypsum surfaces), from materials with concrete, plaster, brick, uneven surfaces. Use Knauf Perlfix only for interior decoration.

How to use:

Before starting work, it is necessary to prepare the base. Clean from all kinds of dirt, remove protrusions. If the walls are highly absorbent, such as silicate, aerated concrete, ceramic elements or plaster, they must first be treated with a Knauf primer - Grundirmittel. And concrete or foam concrete walls are covered primer Knauf- BETOCONTACT. This procedure is essential, it improves the adhesion between the wall surface and the bonded material.

Attention! The primer must be allowed to dry, and then proceed to further work. And do not forget to keep the primed wall clean.

Work technology

Temperature working area must be more than +5 degrees Celsius. Work is best done in normal humidity.

How to prepare dry gypsum glue?

We take a plastic container, pour clean water: for a thirty-kilogram bag you need 15 liters of water. Next, gradually pour out the glue for gypsum tiles or just dry gypsum glue and mix with a construction mixer. The consistency should be creamy, homogeneous without lumps. Do not add other adhesive components to the solution. Mounting adhesive mixture can be used within half an hour. The container for glue and tools must be clean.

Gypsum mounting adhesive is applied at the rate of one trowel per 35 cm. Then the panel is pressed against the surface and leveled with light taps. On a surface with grooves larger than 2 cm, it is necessary to build a canvas from drywall strips, which will play the role of an installation plane. When pasting insulation material, it must first be wiped with a Knauf-Perlfix solution.

At the end of the work, you need to wash all the tools. For 1 m 2 consumption of 5 kg of dry powder.

Storage methods:

Bags with Knauf adhesive powders are stored in a dry room, the floor must be wooden. If the integrity of the bag is broken, it is necessary to pour into sealed containers. Shelf life is 6 months, subject to the above conditions.

Summing up

Among the many mounting gypsum adhesives, Knauf and Volma mixtures have proven themselves to be excellent. Professionals use and recommend these adhesives.

Everyone knows that there are two ways to install drywall sheets on the wall: frame and adhesive. The first one is classic. traditional way which is used all over the place. But the second is a rarity, but it exists. For fasteners in the second way, a special Perlfix drywall adhesive is used, made on the basis of gypsum with the addition of polymer fillers.

The manufacturer of this mortar is the German company Knauf, which is distinguished by the production of high-quality dry mixes and adhesive solutions for drywall. Therefore, we can say that Perlfix glue is a material with guaranteed quality characteristics.

Application area

This material is intended for fastening:

plasterboard sheets;
Combined gypsum panels (GKP);
tongue-and-groove gypsum boards;
Insulating roll and plate materials (mineral and polystyrene foam types).

You can attach all of the above materials to a brick or concrete wall, on plastered or porous concrete surfaces.

Attention!
Mounting adhesive Perlfix can only be used for gluing indoors. They cannot work outside.

This solution is packaged in paper bags weighing 30 kilograms. They can only be stored in dry rooms on wooden pallets. Shelf life is six months.

Very important point, which some ordinary people do not pay attention to is the shelf life. If it has expired, then you should not purchase glue. This is a guarantee that its bonding qualities have decreased, and it is no longer possible to be responsible for the quality.

Conditions for using Perlfix glue

Glue Perlfix for drywall can be used under certain temperature and humidity conditions.

Firstly, the temperature inside the premises where drywall will be glued should not be lower than + 10C.
It is very important that this temperature is maintained not only during the entire repair, but also after it for at least two days.
Secondly, if other leveling processes are carried out in the room (laying the screed on the floor), then it is necessary to wait for all surfaces to dry well. Humidity will decrease, after which you can start sticking drywall sheets.
Thirdly, avoid drafts. Therefore, all work is carried out behind closed windows.

Wall surface preparation

As with any finishing process, gluing drywall is all about a solid and clean wall. Therefore, first of all, the latter must be cleaned of dust and dirt, of grease and paint stains.

If the surface of the wall does not satisfy you purely in terms of strength, then there is a need to harden it. For example, seal cracks with putty.

Attention!
A prerequisite is the primer of the wall. To do this, it is better to use a deep penetration primer (for example, Tiefengrund or Betokontakt from Knauf).
This material, penetrating deep into the wall, strengthens it and creates a layer with a high degree adhesion.

How is the adhesive solution prepared?

In principle, the instructions are on the package. By following it exactly, there is no doubt that the solution will be prepared correctly.

The only thing I wanted to pay attention to:

Mixing of components must be carried out in a clean container (plastic or enameled).
First, water is poured into the container (15-16 liters), then the entire bag is gradually poured, constantly mixing with construction mixer or a drill with a special nozzle.

It is important to ensure that the solution was in the form of a homogeneous mass. If the consistency of the material did not suit you, then you can add either water (you will get a liquid solution) or a dry mixture (to obtain a dense mass). By the way, the "viability" of the finished material is limited to half an hour. So hurry up and work on them.

And one more important point, which concerns such a category as the consumption of drywall glue. Not counting the small losses, for one square meter plane will take up to five kilograms of material.

Installation of drywall with Perlfix glue

The technology of using this glue is quite interesting. To do this, small heaps (hills) of material ten millimeters high are applied to the drywall sheet, for which a metal trowel is used. The distance between the piles is 30-35 centimeters.

The location of the material may be different:

Along the perimeter and diagonally;
Along the perimeter and along the sheet in two stripes (photo above);
Along the perimeter and across the sheet in three or four stripes.

That is, it is necessary to distribute the Prefix glue so that it is spread as evenly as possible over the drywall area. Now you need to attach the sheet to the wall and align it with light blows through the rail. Remember that the alignment process can only be carried out for ten minutes. After that, the glue just dries.

Alternative

The modern building materials market today offers a fairly large range of adhesive solutions for drywall boards. The quality of many of them will not yield to materials from Knauf. For example, Volma glue. An excellent material with excellent physical, technical and operational characteristics.

We will not compare it with other identical materials, because each adhesive solution has its own advantages and disadvantages. The only thing to note is that Volm's price is lower than the cost of solutions from Knauf.

By the way, the Volma Corporation today offers a huge range of adhesive solutions, where I would like to note the tile adhesive "Ceramic", the assembly adhesive "Block" for cement structures etc.

Conclusion on the topic

For many home craftsmen who do some repair work with their own hands, this technology is unusual, so we have posted a video on the website page for you. This is a great help to fully and thoroughly understand the process of gluing drywall to the wall.
