For interior work. Do not use for sealing joints of plasterboard sheets.

AREA OF APPLICATION: For interior work. Do not use for sealing joints of plasterboard sheets.

PREPARATION OF THE BASE: The base must be smooth, strong, with a temperature not lower than +5° C. Clean the surface from dirt, dust and exfoliation, remove any remaining formwork compound from the concrete. It is recommended to treat highly absorbent surfaces with KNAUF-Tiefengrund primer, concrete surfaces with KNAUF-Betokontakt primer. The consumption of dry putty mixture with a layer thickness of 1 mm is 1 kg/m2.

TECHNICAL CHARACTERISTICS: Layer thickness: Minimum 0.2 mm Maximum 5 mm Strength: compressive 4.2 MPa flexural 1.3 MPa Grain size: 0.2 mm

PREPARATION OF THE BASE: The base must be smooth, strong, with a temperature not lower than +5° C. Clean the surface from dirt, dust and exfoliation, remove any remaining formwork compound from the concrete. It is recommended to treat highly absorbent surfaces with KNAUF-Tiefengrund primer, concrete surfaces with KNAUF-Betokontakt primer.

MATERIAL CONSUMPTION: The consumption of dry putty mixture with a layer thickness of 1 mm is 1 kg/m 2.

PACKAGING AND STORAGE: The mixture is packaged in paper bags of 25 and 20 kg. Store bags in a dry place on wooden pallets. Use damaged bags first. Shelf life in undamaged packaging is 6 months.

OPERATING PROCEDURE: pour Knauf Rotband-Finish into a container with clean cold water up to the water level mark (in the ratio of 1 kg of mixture per approximately 0.65-0.7 liters of water or 1 bag (25 kg / 20 kg) for approximately 16-17 l / 13-14 l of water), evenly distributed over the surface. Leave the solution for 2-3 minutes to absorb, then mix with a spatula or mixer at low speed until a homogeneous mass is formed. If it is necessary to level out significant unevenness, the putty should be applied with a thicker consistency. When applying putty to large surfaces, work with a trowel or Swiss falcon. The working time with the solution is 90-100 minutes. Do not use thickened putty solution. Adding water and stirring does not restore its working properties. Uncleaned containers and tools reduce the time spent working with the mortar mixture. All subsequent work (wallpapering, painting) should be carried out only after the material has completely dried. If necessary, the putty surface can be sanded.

Universal gypsum plaster Knauf Rotband

This is a universal material of the Rotband brand with a volume of 30 kg. It is used to perform exclusively internal preparatory work for cladding. Used for plastering ceilings on a solid base of brickwork, concrete, and cement plaster. To obtain the highest quality coating, it is necessary to create an optimal level of humidity in the room. Consumption per 1 m2 does not exceed 0.95 kg, but it should be taken into account that this calculation is relevant only if applied in one layer 1 mm thick.

Gypsum plaster Knauf Rotband

Using the mixture, you can create a perfectly smooth surface in one layer or several. Remember, before applying each subsequent layer, you must wait until the previous one has completely dried. The material is resistant to cracking due to the presence of polymer components. It is completely environmentally friendly, which is why it is often used for children's rooms.

It is recommended to apply the solution in a layer up to 5 mm thick. The material can be used as putty to create a multi-layer structure. The mixture is distinguished by its increased moisture-retaining property, which allows it to be used in combination with a base that strongly absorbs water. Also, this factor allows the walls to “breathe”, which allows you to regulate the microclimate in the rooms. The price of the package varies within 300 rubles.

Knauf-Rotband paste Pro

This is a ready-made finishing putty that contains vinyl components. The material has a perfectly white color, a high degree of adhesion and resistance to cracking. Knauf Rotband putty paste is recommended for use indoors for the final preparation of walls and ceilings for painting, wallpapering and other decorative cladding.

The material is packaged in buckets of 5 and 18 kg. Can be applied either manually or using auxiliary machine tools. Consumption per 1 m2 with a layer thickness of 0.3 mm is approximately 0.48 kg. This is significantly less than the parameters of bulk mixtures.

Technical characteristics of Rotband putty paste:

The cost of a container weighing 18 kg is 805 rubles.

Drying the putty

• A layer of one millimeter dries within 24 hours. And a layer of three millimeters - within three days.
• Humidity should not be more than 60 percent.

Color palette

It comes in pink, gray and white. Depends on the additives.

Using pink putty, the walls are perfectly smooth. And after gray and white putty, waves form on the surface. They will need to be smoothed out.

Rotband putty consumption

Usually in stores putty is sold in paper bags. For small volumes, you can purchase putty weighing 5 kg. And if necessary, you can buy putty

Rotband weighing 30 kg. If the thickness of the putty is one centimeter, then 9 kg of mixture will be required per 1 square meter. Therefore, a large bag weighing 30 kg is enough for a surface with a volume of 3.5 m2.

Rotband Paste is used to treat a small surface. This mixture is already ready. There is no need to breed it anymore.

How to mix and apply the solution

To mix and apply the Rotband putty mixture, you will need the following tools and materials:

1. Bucket (or some kind of mixing container).
2. Construction mixer.
3. Spatulas (of various shapes and sizes - selected for the object of work).
4. Sanding materials (sandpaper or float).

Before mixing the putty, it is necessary to carry out preparatory work. The surface should be cleaned of dirt, dust, protruding fittings or other objects. Then treat all metal parts with an anti-corrosion solution.

Next, treat the surface with a primer. Depending on the type of surface, different types of primer are used. Before starting work, the temperature of the wall (or other surface) should not be below 5°C.

After completing the preparatory work, the putty mixture is mixed. It is recommended to make batches in small portions for better mixing and to prevent the mixture from drying out. The putty is poured into a clean mixing container and filled with clean cool water at the rate of 1 kg of mixture per 0.7 liters of water (a 20 kg bag is filled with 13.5 liters of water, a 25 kg bag is filled with 16.5 liters of water), as the instructions say. A couple of minutes after pouring, the putty begins to be mixed. First, the mixture is mixed by hand, then with a mixer operating at low speed.

Ready putty Rotband

Stir until the mixture becomes homogeneous, similar in consistency to sour cream. The temperature of the room and water should be within 10-25 oC. At temperatures different from those specified, cracks form on the putty surface. Do not add foreign mixtures or additives to the putty. It is also prohibited to use a dried and thickened solution. The solution can only be used within 1.5 hours from the end of the batch. Apply the solution to the wall only with clean stainless steel spatulas.

The solution is applied to the surface with a spatula, then leveled to the required thickness. You can level the solution with a spatula, a Swiss falcon, or using a rule. After applying the putty, the tool should be washed. Tools should also be cleaned of dried large fractions of the solution if they are formed during the puttying process.

The putty solution should dry in the dark (or should be protected from sunlight) and in the absence of drafts.

How to work with Rotband putty

First, the wall must be cleaned of wallpaper and old paint. Then you need to remove the dirt. Then the walls are primed.

• Dry Rotband putty is added to a bowl of water. The proportions are written in the instructions. Then, by hand or using a construction mixer, the mixture is thoroughly mixed. Then you need to leave the mixture alone for a while.
• The prepared mixture must be applied to the walls with a special spatula. The thickness of the layer can reach five centimeters.
• The process of leveling the walls occurs from top to bottom. And the ceiling is leveled by moving towards itself.
• Grouting is carried out as soon as the plaster begins to set. The plaster is sprayed with water and begins to shine.
• Putty that has not yet completely dried can be given a certain structure. This can be done using tools such as a sponge, comb, brush and so on.

Rotband dries completely within seven days. This process is affected by temperature and humidity.

Finishing gypsum putty “KNAUF-Rotband Finish”, 25 kg

Preparation of the solution

Pour KNAUF-Rotband Finish into a container with clean cold water up to the water level mark (at a ratio of 1 kg per 0.65-0.7 l) or 1 bag (25 kg) for approximately 16-17 l of water. After 2-3 minutes, mix by hand or using a mixer running at low speed until a homogeneous mass has the consistency of sour cream. The water temperature for mixing the dry mixture should be in the range from +5°C to +30°C. Warmer water degrades the water-holding capacity of the putty and can cause cracks in the putty. It is not allowed to add other components to the putty mixture, as this leads to a significant deterioration of its properties! Do not use a thickened putty solution; adding water and stirring will not restore its working properties. Contaminated containers and tools help reduce the length of time the material can be used. The duration of maintaining the working properties of the putty solution before thickening begins is at least 80 minutes.

Application and leveling

When completely puttingtying surfaces in one layer, apply the material to the surface in an even layer and level it with a wide spatula or trowel. After spreading the material, the surface should be smoothed, removing excess material and filling the depressions. If necessary, apply excess mixture to other areas of the wall. When working on large areas at a room temperature above 25°C, it is recommended to work in two layers, when, after the initial smoothing of the material and its complete drying, a second layer is applied “scraping”. The mixture from the spatula must not be returned to the bucket to avoid premature setting of the composition. The pot life of the mixture is at least 80 minutes. The processing time of the material on the wall may differ from the pot life of the mixture and depends on a number of factors (air temperature, absorbency of the base, etc.). Do not use thickened putty solution. Adding water and stirring does not restore its working properties. Uncleaned containers and tools reduce the time spent working with the mortar mixture. Wash equipment and tools with water immediately after work. All subsequent work (wallpapering, painting) should be carried out only after the putty has completely dried. Remove possible irregularities by sanding.

Recommendations

Do not use at temperatures below +5°C and above +30°C. High temperatures reduce processing time. Avoid direct sunlight on undried putty and avoid drafts in the room when the putty is drying. All tools used in the work process must be made of stainless materials.

Tools

• Container for preparing putty solution.
• Metal spatula-trowel for mixing putty.
• Plaster mixer (N ≥ 800 W).
• Wide metal spatula (200-300 mm wide).

Secrets of using Rotband

Use according to instructions.

• In order for the walls to dry faster, you need good ventilation in the room.
• Before using putty, the walls must be treated with a primer. Thanks to this, Rothband will do better.
• The volume of the mixture is calculated based on the area of ​​the room.
• Especially beginners in repairs should dilute small volumes of the mixture.
• It is better to dilute putty in small plastic buckets.
• First of all, water is poured into buckets. Then fill the putty according to the instructions. You can stir by hand. But it will work faster if you use a construction mixer.
• It is better to pour less water than necessary. If anything, you can top it up at the end.
• Putty hardens in cold water longer, in warm water faster.
• After the ingredients are mixed, you need to let the mixture rest for about 10 minutes.
• Apply the second layer using a cleaned tool. The mixer should also be washed immediately after preparing the solution.

In order for the putty to dry faster, the room must be thoroughly ventilated after completion of the work.

Advantages and disadvantages of Rotband putty

The advantages of Knauf Rotband putty include:

1. Formation of an almost ideal smooth surface that does not require additional putty.
2. Even with a thick layer of putty, cracks do not form (subject to proper drying conditions).
3. Gypsum plaster is consumed several times less than sand-cement plaster.
4. Possibility of applying 50 mm of marking at a time.
5. Gypsum putty is universal. It allows you to simultaneously plaster and putty, perform decorative stucco molding, seal small cracks during minor repairs, etc.
6. The dried putty solution is durable, resistant to water, and does not peel off even on porous surfaces and at high temperatures.
7. The putty is “breathable” and regulates heat and moisture exchange in the room.
8. When making the mixture, pure gypsum is used without any foreign impurities.

Available disadvantages of the mixture:

1. High price. Domestic mixtures and Volma-layer are not inferior in quality, but cost almost 1.5 times less.
2. The solution thickens very quickly, which can create inconvenience when filling large areas.
3. There is shrinkage of the putty.
4. When kneading, you must use a respirator. The mixture is fine-grained, which ensures that it enters the respiratory tract.
5. After the putty dries, its color may change.
6. Due to the rapid drying of the mixture, it is problematic to apply a second layer.
