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. You also need to pay close attention to the subsequent finishing.

Tiefengrund

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.

Tiefengrund is a versatile primer. It can be used to treat a variety of surfaces.

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. Thus, the consumption of building material will be reduced. Priming must be carried out at an air temperature of at least 5 ° C.

Estrichgrund

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.

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.

It is necessary to use the plaster immediately after the primer is completely dry. If you slow down a little, then household dust will settle on the material and thus the adhesion will be significantly reduced.

How to choose?

A correctly selected primer ensures good adhesion between the base and finishing materials.

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.
• The fortifying composition can be applied on substrates that do not require any treatment. It will be more economical.
• It is necessary to determine the type of solution, while evaluating its transparency.
• For processing in rooms with high humidity, it is worth using antifungal primers. They will protect the room from mold.
