Knauf Primer: Properties and Applications

Primer is a necessary material during finishing work. The composition is used for decorative processing, it improves not only aesthetic, but also the technical characteristics of the coating. At the expense of a number of advantages the primer from the Knauf trademark enjoys special popularity.

The process of priming the floor and walls is a significant step in the repair process. It is carried out both when finishing residential and commercial premises. The composition provides strong adhesion between the surface and decorative material - paint or varnish.

The trademark Knauf is a European brand whose products are in demand in the Russian market. The compositions meet high quality standards, and each product has its own specifications. The brand uses in the production of innovative equipment and modern techniques, special attention is paid to the choice of raw materials.

Primer "Knauf" has several advantages thanks to which it has become popular among consumers:

• advantageous consumption of the composition;
• environmental friendliness - the primer is safe for allergy sufferers, pets and small children;
• full compatibility with the materials of the above brand;
• high resistance to moisture, the vagaries of climate, temperature fluctuations and other external stimuli;
• “Breathability” - the material passes air, due to which a favorable microclimate is created in the room;
• reliable and durable grip.

In the product catalog of the European manufacturer Knauf, you can find many compositions, each of which has its own individual characteristics. Below are the most popular primers.

The Estrihgrund product is ideally suited for priming work on a seamless floor. Processing composition several times reduce the water-absorbing capacity of the base.Also among the positive qualities distinguish improved adhesion.

Before use, it is desirable to dilute the material with water in accordance with a 1: 1 ratio. According to the texture of the product is a viscous composition. If the surface has an absorptive capacity, then it is recommended to coat it with a primer in two layers. In this case, the first time it is necessary to treat the base with a solution in a ratio of 1: 2, and the second layer - 1: 1.

Before applying the composition surface must be thoroughly cleaned and dried. You should get rid of particles of old paint, oil stains, dust and other contaminants. The primer is applied with a brush or a special roller - this should be done evenly so that no puddles form on the floor. After application, it is necessary to leave the primer to dry. Approximate time of full hardening - 24 hours. If you want to reduce the time spent, you should open the window in the room, thereby ensuring a thorough ventilation. Work also proceeds faster in a room with warm air.

When processing a dry screed floor, the consumption will be 50 g per 1 square meter. m. This figure is doubled if the work is carried out on the floor of calcium sulfate.The product is stored in sealed sealed containers throughout the year. Optimum temperature conditions for storage is a positive indicator. Universal packaging 10 liters - standard packaging.

Universal acrylic product "Tiefengrund" has a colorless texture. The material penetrates deep into the surface fibers. The basis of the composition of water, artificial resin, resistant to saponification, as well as additional components. In the manufacturing process, manufacturers discard solvents and plasticizers. The primer treatment strengthens the base by adjusting the absorption process.

Features:

• steam capacity;
• reliable grip;
• deep penetration;
• fire resistance;
• economical consumption: 70-100 ml per 1 cu. m

The composition "Tiefengrund" is a versatile tool that can be used for both interior and exterior decoration. The material is suitable for processing the following surfaces:

• drywall (gypsum plasterboard);
• gypsum fiber boards;
• cement fiber boards.

Grundiermittel emulsion is a polymer solution characterized by high alkali resistance. The product is obtained by improving the polymer dispersion. There are no solvents in its composition. The primer is recommended for use on surfaces with high absorption. These include aerated concrete, brick (silicate) and other materials.

Before use, the mixture is diluted with water. There are two main ratios: 1: 2 and 1: 5. It all depends on the ability of the surface to absorb the composition. It is recommended to apply the product with a fur roller or brush.

Advantages of the Grubinmittel solution:

• adhesion index grows several times;
• increases the strength of individual materials and bases;
• absorbency is adjustable.

Consumption products - from 200 to 300 ml per 1 square. m

This primer has been developed specifically for surfaces with low absorbency.In the manufacturing process the company used quartz sand. This polymer dispersion is highly alkali resistant.

The composition can be used to work with different surfaces:

• low absorbency base;
• dense and smooth canvas.

Technical aspect:

• material is applicable for interior work;
• high crack resistance;
• has a pink color;
• drawing happens as a manual method, and by means of the professional construction equipment;
• The product is sold ready to use.

If the work occurs with concrete, it is necessary to apply the solution in the form in which it is sold, without additional dilution. On less dense bases the product is diluted with water: 1 liter of liquid per 20 kg of composition. This consistency is recommended when working with the sprayer.

The solution dries completely within 24 hours if the room temperature is set at 20 degrees above zero. Optimum air humidity is 65%.

Apply a second decorative layer, such as plaster, can only be after the full drying of the primer. Experts advise to carry out the procedure immediately after solidification, so that dust and minor impurities do not accumulate on the layer.. Consumption in pure form: 0.25-0.35 kg per 1 cu. m

Experts point out that this is an ideal choice for combining with decorative plaster. The material is white in color, using quartz sand. This is a pigmented synthetic dispersion, which is used for processing various bases: concrete, gypsum fiber, gypsum cardboard.

Benefits:

• universal use: material is applicable both for internal, and for external works;
• reliable grip base and finish;
• air circulation;
• alignment of the surface color;
• resistance to moisture and dampness.

The primer is great for repair work with white plaster. In the process of work, it is necessary to ensure that the material and the surface have a temperature of about +5 degrees. Do not forget to thoroughly mix the composition. Consumption is 200-300 g per 1 square. m

Knauf company offers customers a high-quality emulsion based on a silicone component. The material is designed to design both old and new surfaces. The composition is ideally combined with decorative and thin-layer plaster, it can be used for work inside and outside buildings.

Before applying it is necessary to mix the composition thoroughly. The consumable material is applied on the base with a roller or a special brush. Then it is allowed to dry. You can continue to finish no earlier than 12 hours after application. Consumption is about 200 g per 1 square. m. Packaging for 15 kg should be enough to finish 75 square meters.

“Haft Emulsion” is a deep penetration compound with a concentrated consistency. If work is carried out with a highly absorbent base, then it is recommended to use this particular primer.The product is often used for pretreatment, before puttying.

Technical features:

• excellent compatibility with compositions based on alkali;
• increased resistance to oil, gasoline, saponification and acids.

The mortar can be used to treat surfaces based on cement. The composition will give the surface reliability and stability. In addition, due to the special components on the material less dust accumulates. The primer is perfect in order to improve the spackling and leveling mixtures and protect the floors from constant loads and wear resistance.

Store the composition preferably at above zero temperature. The material will withstand slight temperature drops up to -5 degrees.

To make the right choice, you need to carefully study the diversity of compositions and their individual properties. Each solution is made taking into account the peculiarities of the climate and other external factors. Components included in the composition, have a certain impact. An excellent result will be achieved only if you use a quality primer and strictly follow the instructions for use.
