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 use for it is the creation of glue, which is usually used for pasting gypsum boards, gypsum-based panels and decorative gypsum parts. The article will give a brief overview of the leading manufacturers of this product, as well as talk about its advantages, disadvantages and features.

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, 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.

Gypsum assembly adhesive 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.

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.

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:

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.

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.

A company that cooperates with KNAUF. A 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 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.

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

As a result, you should have a consistency similar to sour cream. Lumps and various clots should not be present.

Gypsum assembly glue is a modern building mixture that perfectly copes with its main function. The leader is the manufacturer Knauf, but the company VOLMA and Gypsopolymer are not lagging behind in quality. This binder can be used by both professional renovation professionals and newbies. Suitable for industrial and home use. You can find gypsum-based glue at any hardware store.
