Gypsum glue: what is it, what is it used for?

Such material as gypsum is actively used in the creation of building materials. The most common variant of its use is the creation of an adhesive, which is usually used for pasting gypsum plasterboard, gypsum-based panels and decorative plaster parts. The article will provide a brief overview of the leading manufacturers of this product, as well as talked about its advantages, disadvantages and features.

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

Most often it is used in the following situations:

• When installing GWP and GVL, where the adhesive acts as the main binder material. These plates are large, they can be used to quickly build partitions, so there is a need for glue, which quickly sets. In this case, gypsum glue is the main competitor of the foam.
• For wall cladding with gypsum tiles and artificial stone. Basically plaster glue is used for interior work.
• When plasterboard / gypsum-fiber sheets in the form of rough finish are to be stuck onto walls or ceilings, 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 you compare this type of glue with other types or cement, you can identify the disadvantages:

• The structure of the mixture after hardening is brittle, so it is not suitable for use under flooring.
• Glue is not characterized by moisture resistance and loses its properties when in contact with water, so it can not be used for exterior decoration or in rooms with high humidity.

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

Use this type of glue mainly for large-scale repairs. This causes the fact that many manufacturers pack this material in large bags of 30 kilograms. It is almost impossible to meet small packages, however such ones are also found.

Gypsum adhesive is characterized by many advantages:

• It is prepared easily and quickly.
• When mixing, practically no lumps are formed.
• Installation does not require frame installation.
• Differs in the increased durability.

• Dries relatively quickly.
• Spent sparingly, therefore, comparing with conventional types of glue, which are inexpensive at cost, the gypsum type pays off quickly enough.
• Apply a thin layer, therefore, saves room space. In addition, this leads to the previous advantage - material savings.
• Durability due to the addition of water-retaining additives.
• Cement mixtures require the implementation of operational work, and the adhesive composition does not need to rush.
• You can create the minimum thickness of the seam between the blocks / plates for cladding. For example, the manufacturer of plaster glue Knauf guarantees that the wall does not freeze.

Mostly gypsum composition is produced in the form of a dry powder. This type of mixture is very convenient to use. In order to improve the adhesion properties, special substances are added to the main components of the composition, which, in addition to increasing the binding properties, make it possible to work with the glue slowly.

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

The main task of this composition is the creation of a strong adhesion to the surface. In the market of building materials you can find plaster glue, which contains a large amount of gypsum. This affects the adhesion of the binder to the surface. Determine the quality of this product can also by the amount of water required for the preparation of glue. This amount can usually be read on the package. For example, if it is indicated that 300 ml of water is required for one kilogram of composition, this indicates that a small amount of gypsum is present in the composition, due to which its adhesive properties are reduced. Acquiring a similar adhesive material, you must be prepared for the fact that it can peel off during operation.

There are a lot of companies that produce gypsum mounting glue. We consider the most famous of them, characterized by good quality product:

Makes plaster glue in a package of 30 kilograms. The product from this manufacturer is the most popular product, because it has a good German workmanship.

The disadvantages of the considered product include only the following parameters:

• relatively high cost, due to the fact that it is a branded product that has an advanced manufacturing formula.
• unstable quality, which is due to the fact that the company has 10 productions, which are also engaged in gypsum glue. Due to the complexity of transportation, the product comes from the nearest factory, where the quality may be lower than in the central one. Some products received negative customer reviews.

Excellent Volgograd company that manufactures high-quality gypsum product using a unique technology. Among builders, this manufacturer has an excellent reputation. Many construction companies use Volma plates and mixtures. As noted earlier, it is extremely difficult to find plaster glue in small bags, but the manufacturer under consideration produces packages of five and 10 kg. Despite the presence of such packaging, finding them on the shelves of stores is problematic, since builders do not need such a volume, and private owners buy such goods quite rarely.The advantages of Volma's gypsum composition are high quality and affordable price.

A company that collaborates with KNAUF. The German company manufactures components for it to create a plaster glue. It should be noted that the German company wants to make a "Gipsopolimer" list of subsidiaries, but the Perm manufacturer still remains independent. Comparing with the previous types of gypsum glue, it is important to notice the relatively low cost, while the quality of the product does not suffer from this. Exactly inexpensive price has become the main criterion for creating competition for previous brands.

As previously noted, the gypsum adhesive is preferably provided in the form of a powder. Mix it with water in a plastic container. Initially, it is necessary to pour water into it, to which glue will be gradually added. Mix the composition must be carefully, so it is best to use a special mixer for this.

As a result, you should get a consistency similar to sour cream. There should not be lumps and various clots.

Gypsum mounting adhesive is a modern building mixture that copes with its main function. The leader is the manufacturer Knauf, but the company VOLMA and Gipsolymer do not lag behind in quality. This binder can be used both by professionals in the field of repair and beginners. Suitable for industrial and home use. Find glue based on gypsum at any hardware store.
