Eco-friendly Knauf Rotband plaster

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.

1993-1997

Meanwhile, in 1993, the management of the Knauf company made a decision to start production activities in Russia. The first enterprise to produce dry gypsum plaster in Soviet times was a plant in Krasnogorsk.

In 1997, a plant for the production of dry building mixtures was built on the territory of the enterprise, which began the production of modified gypsum mixtures, the first of which was KNAUF-Rotband. This year can be called revolutionary for all plasterers in Russia. Together with Rotband, Knauf offered a new and more efficient technology.It took some time for Russian builders to appreciate all the advantages of the new product, because for many years they got used to working using a ratchet to level the walls. However, the efforts of KNAUF specialists, who conducted training in the technologies for the use of dry mix, have borne fruit. The builders, having tried European technology with their own hands, irrevocably abandoned traditional unmodified mixtures.

Finishing putties from renowned manufacturers

Volma finish. A mixture based on gypsum and mineral fillers, which, when dry, becomes strong and resistant to cracking. It is used for surface preparation for painting and wallpapering.

Knauf-Hp Finish. It is used for surface finishing in rooms with normal humidity. Layer thickness - up to 3 mm. Does not crack or shrink.

Knauf Rotband Finish. Finishing plaster mix. Layer thickness - up to 5 mm. It is used for filling concrete surfaces, gypsum board, gypsum plasterboard.

Vetonit. Vetonit LR + is intended for use in dry rooms. It is considered a medium fraction putty. It is applied in a layer of 1 - 5 mm. Easy to sand. Vetonit VH - is used both in dry and in damp rooms. Applied to concrete, brick.

Vetonit KR is well suited for finishing puttying on prepared surfaces. Creates a thin, durable layer.

Sanding of surfaces should be started no later than 2 days after drying.

Then the process is very easy. Suitable for subsequent painting and wallpapering.

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.

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.

What is the difference between start and finish?

To begin with, consider what criteria for dividing the putty exist.

By composition:

• Plaster;
• Polymeric;
• Cement;
• Glue-oil.

According to the degree of readiness:

• Ready-made solutions used for direct application to the wall;
• Dry mixtures to be diluted in water and then used.

By fraction and grain size of the base material:

• Starting;
• finishing;
• universal.

All putties are divided into starting and finishing. This division is somewhat arbitrary, since the starting putty can sometimes be used as a textured base before applying paint. And the final mixture, on the contrary, before gluing complex wallpaper.

The division of the putty into starting and finishing is determined, first of all, by the size of the base filler fraction.

In starting putties, the size of the grains of sand is larger, which allows you to apply a thicker layer and not be afraid of shrinkage and cracking. The relief of the walls after applying such mixtures turns out to be rather coarse and grainy and requires subsequent finishing.

Such surfaces cannot be sanded to a perfectly smooth state.

The main purpose of starting putties is to create a base layer for finishing. Such mixtures can be applied in a layer up to 5 cm. They perfectly cover all depressions and small bumps.

Finishing putties outwardly resemble a pasty mass with small filler particles. There are no large grains of sand in it. Its creamy consistency lays down on the walls in a thin layer and fills in all the smallest flaws and irregularities. Such walls are easy to sand and become perfectly smooth. Paint and decorative plaster fit well on them.

Most often, starting and finishing putties are used in combination. The first layer, depending on the degree of unevenness of the walls, is the starting mixture. Second, after high-quality drying and sanding, a finishing putty is applied.

Betokontakt

If you need to treat a surface that has poor absorbency, then you need to purchase Knauf 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:

• suitable for interior work;
• 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.

The primer must be applied undiluted to the concrete surface. 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.

1962

Then the company KNAUF developed the composition of the plaster mixture for interior work and released it on the market in 1962 under the name "Rotband". For 55 years, many good gypsum plasters have appeared on the world market.The "Rotband" recipe has improved over time, gradually it has become the most popular material of its kind.

Not so long ago, in the early 90s, there were no ready-made modified mixtures for rough finishing on construction sites in Russia. Workers on the spot prepared plastering compounds, like their German counterparts in the middle of the last century. Despite the fact that each master, as a rule, had his own secrets, it was difficult to get a guaranteed high-quality result with this technology.

Starting putties for walls - types

In terms of composition and intended purpose, the starting putty is a transitional stage between plaster and finishing mixtures. It, like plaster, is used to treat rough surfaces. However, at the same time, the structure of the starting putty is not as coarse as that of plaster and allows the application of a finishing layer.

In particular, start putty is suitable for:

• finishing around door and window frames;
• filling strobes;
• alignment of slopes.

Starting putties are divided into homemade and ready-made mixtures. They resort to self-preparation of the putty, if necessary, to save financial resources. In this case, all the constituent parts are mixed in the right proportions. It can be gypsum-chalk and oil mixtures.

However, in practice, this happens quite rarely. Basically, ready-made mixtures are used for repairs. In them, all the constituent parts are selected, and the only thing that needs to be added is the right amount of water. Ready mixes are of the following types:

• cement;
• gypsum;
• polymer.

Here is a list of the most common companies that produce starter putties.

Volma. The company specializes in the production of ready-made putty mixtures and produces base and finishing putties. There are several starting mixtures:

• Aquastandard is a cement putty used to level surfaces for decorative coatings - textured paint, plaster.
• Volma-Standard base putty is a gypsum-based mixture used for the main leveling of walls, ceilings for painting, wallpapering, decorative plaster.
• Base cement putty. Designed for basic finishing of walls and ceilings in dry and damp rooms. It is also used for facades.

Prospectors. Russian manufacturer of starting putty.

The white cement-based mixture is used indoors and in the decoration of façades. Does not crack or shrink. When dry, the putty forms a waterproof layer, therefore it is widely used for repairs in bathrooms and toilets. Surfaces can be easily sanded both by hand and using special equipment.

Knauf. Ready mixes Knauf are deservedly considered one of the market leaders.

Combining the high quality of the constituent materials and ease of use, they are loved by many builders and repairmen.

Knauf putties are of 3 types:

1. starting;
2. finishing;
3. universal.

Knauf starting mixtures:

• Start Rotband for indoor use - used for leveling brick, concrete, expanded polystyrene, gas-block bases, easily applied to walls and ceilings.
• Knauf Goldband. Possessing the above properties, Goldband is used only for wall decoration. It contains no adhesive components. This mixture works well when processing concrete and brick walls with deep depressions. It is applied in a layer up to 5 cm.
• Knauf Fugenfüller. Starter type gypsum putty for sealing drywall joints. It is characterized by special strength and crack resistance.

Vetonit. The Vetonit company is represented by a wide selection of starting and finishing putties. Vetonit TT is a starter filler for dry rooms and rooms with high humidity levels. It is applied in a layer up to 6 mm., Does not crack, is not afraid of frost.

Acrylic fillers.The main substance that determines almost all the characteristics of such a mixture is synthetically made acrylic. It has a unique ability to change its properties depending on the conditions acting on it. The advantages of such a putty in:

• high plasticity of the created surface;
• creating a water-repellent layer;
• fast drying;
• easy application and sanding;
• environmental friendliness;
• fire safety;
• no shrinkage;
• long service life.

Acrylic starter fillers are designed to correct the most serious defects and surface imperfections. Acrylic putty mixture is produced ready-made - in plastic buckets. Among the firms producing acrylic putty, one can distinguish Ural quartz, Lacra, VGT, Parade.

How to make the right choice for drywall?

So that the quality of the repair leaves no doubt, when choosing ready-made solutions, one should be guided by some circumstances:

• the material from which the surfaces are made;
• estimated operational humidity of the premises;
• location of premises inside the building, or on the street;
• the main material of the starting putty in the case of applying a finishing layer on it.

To choose a plasterboard putty, it is important to take into account the specifics of the upcoming work. GKL and GVL finishing works include the following procedures:

GKL and GVL finishing works include the following procedures:

1. sealing of seams;
2. applying a finishing layer.

Due to the fact that the surface of drywall sheets is already intended for applying the finishing layer, the starting layer must be used when sealing the most vulnerable parts that are most susceptible to deformation. These are the seams.

For the treatment of seams, starting gypsum mixtures of a coarse fraction with high resistance to shrinkage and mechanical stress are used. The starter layer is applied in two stages using a paint net.

Builders and specialists in repair and finishing work when finishing drywall partitions advise using gypsum putty mixtures. And there are a number of explanations for this:

• this mixture does not shrink;
• gypsum adheres perfectly to drywall;
• easy to apply and level;
• dries quickly.

Attention! When decorating walls in rooms with high humidity, moisture-resistant gypsum board and putty with water-repellent fillers should be used

Features and properties of the universal primer
