Knauf primer: characteristics and application features

Priming walls and flooring is one of the most important stages in the renovation of any room. It provides high-quality adhesion of all finishing materials to your surface. Today the construction market offers a wide range of products required for priming. It differs among themselves in two parameters - the method of application and composition.

The choice of primer mix will depend on several factors. For example, on the type of surface that needs to be treated, as well as on the humidity indicators in the room. It is also necessary to pay close attention to the subsequent finishing.

Knauf is recognized worldwide as a reliable manufacturer of building materials. It offers its customers a wide range of products at affordable prices. The products of this company are produced in one hundred enterprises located in China, America, Europe and other countries. That is why the geography of sales of this brand is quite wide.

Knauf is engaged in the production of many building materials, including primers, which have different modifications.

Among the advantages of primers of this brand, the following points can be noted:

• They are fully compatible with most of the finishing materials on the modern construction market.
• The composition is designed in such a way as to minimize its consumption during application.
• The primers of this company can be safely used for finishing the facades of buildings. They are resistant to temperature changes and moisture resistant.
• The composition does not retain air, which provides an excellent microclimate in any room.
• The mixtures are completely safe for the human body, environmentally friendly.

The only drawback of this company's primers is their cost. Many companies in the modern construction market offer identical products at a lower price. For many buyers this fact turns out to be decisive and they purchase mixtures from other companies.

If you are looking for a versatile acrylic primer then choose Tiefengrund from Knauf. It is a quick drying solution that is colorless. It penetrates deep enough, and this is one of its main advantages. Its composition is based on an aqueous dispersion. It does not undergo saponification. Tiefengrund does not contain any plasticizers and is suitable for drywall applications.

This type of primer perfectly strengthens any surface. With its help, you can regulate the ability of the material to absorb excess moisture.

Main technical characteristics:

• penetrates deep enough;
• has the ability to bind dust settling on the surface;
• does not retain moisture on the surface, but allows it to pass;
• fireproof;
• the consumption of the primer is minimal.

It is suitable for both indoor and outdoor use. Application area:

• When creating a screed. Basically, ready-made parts are used for this. Suitable for slabs made of various materials, including plasterboard.
• Provides moisture protection on gypsum parts.
• Before laying all types of slabs, they must be pre-treated with Tiefengrund primer. This will help protect them from moisture.
• For priming facades and other outdoor works.
• Surface treatment before painting.

The primer is applied to the wall covering with a regular brush. It is more convenient to apply it to the ceiling with a roller. This will reduce the consumption of building material. Priming must be carried out at an air temperature of at least 5 ° C.

Estrichgrund is a cementitious primer mainly used for screed floors. It greatly reduces the ability to absorb moisture, and also increases the adhesion of screed floors, especially combined ones. These are the main advantages of this solution.

Estrichgrund has a viscous consistency. It must be diluted with plain water before use. The proportion should be 1: 1. A surface that has a high absorbency should be treated not once, but twice.

Application method:

• Clean thoroughly and dry thoroughly. There should be no household dust or paint from the old coating on the surface to be treated.
• The primer must be carefully applied with a construction brush or roller to the floor covering, without leaving any puddles.
• The surface must be left to dry for a while. This will take about a day. It is imperative to ventilate the room during work. This way you will not only protect yourself, but also speed up the drying time.

You can purchase this solution in special plastic buckets. Their weight is 5 or 10 kilograms. It is necessary to store the solution at room temperature, always in a closed container. After opening, the solution must be used within one month.

If you need to treat a surface that has poor absorbency then you need to purchase Knauf's Betokontakt primer. It is a polymer dispersion that is sufficiently resistant to any alkali. It contains quartz sand. This mortar is suitable for use on concrete.

Specifications:

• alkalis have no effect on this composition;
• you can apply with a regular construction roller or use special equipment for this;
• the solution has a pink color for more convenient application;
• no need to dilute the primer, it is completely ready to use.

Apply the primer to the concrete surface undiluted. If you use it on less dense surfaces like enamel, then you can add a little water to it - about one liter of clean water for 20 liters of primer. Use the same solution if you apply it to the surface through a special spray bottle.

Betokontakt dries up within 24 hours. The optimum temperature for quick drying is 20 ° C. Air humidity should be no higher than 60%. By adhering to these recommendations, you can reduce the drying time of Knauf Betokontakt.

Another polymer emulsion resistant to alkali from Knauf is Grundiermittel. In its composition, it does not contain any solvents. This is one of its main advantages. Suitable for use on surfaces that have good absorbency. Among them are brick and foam concrete.

Scope of application of the Grundiermittel:

• used as a base for gypsum-based plaster;
• for self-leveling screeds;
• before laying tiles.

The main advantages of the Knauf Grundiermittel:

• helps to improve adhesion;
• strengthens the surface;
• increases the ability of the material to absorb excess moisture.

Produced by Grundiermittel in plastic buckets weighing 15 kilograms.

Putzgrund from Knauf is a white dispersion. It is completely synthetic and has certain pigments. This primer can be called a narrow profile. And this is indeed a true statement.It is only used before applying the decorating plaster.

The main advantages of Knauf Putzgrund:

It is better to immediately purchase a high-quality solution and avoid all these troubles.

Criteria for choosing a primer from Knauf:

• The primer and the material for further finishing must have the same base.
• An important criterion is the type of foundation. Deep action solutions contain the smallest particles. Fortifying solutions interact only with the surface. This must be taken into account when purchasing.
