Features of plaster

Germany’s KNAUF RotBand plaster is a dry gypsum polyfunctional plaster mixture that has, quite rightly, dominated its market for many years. The "Red Ribbon" is the translation of the German word "Rotband." Karl Knauf, the company’s founder, suggested putting this idea into commercial use to differentiate different product lines for marketing reasons. Thin-layer putty and materials for ornamental decoration, such as "Rothband Finish" (dry mix) and "Rothband Profi" (pasty-like mass), are also available in the Rotband line.

For interior work, "Rotband" gypsum plaster is utilized. It is perfect for applying wallpaper, tiles, and other finishing materials, leveling and getting ready for painting, and decorating walls and ceilings. The inclusion of a unique Alensal Mount additive sets "Rotbanda" apart from regular gypsum mixtures, which are frequently made on-site at a construction site. As you are aware, gypsum setting processes freeze quickly, and this additive slows them down. The solution can be started in larger quantities and used for a longer period of time because of its composition.

Additional benefits of this brand’s gypsum plaster include:

1. Universality. The material is suitable for many purposes – they can carry out black processing, finish and even decorating surfaces. Rotband will fill in cracks and chips, eliminate small and large defects, increase adhesion between decorative trim and wall. Even in the absence of a primer, the plaster will complete its task.
2. High quality. The plaster is valued by masters, as it invariably has efficiency, perfectly even texture, lack of extraneous impurities, excellent adhesion with most building materials (GKL, concrete, OSB, cement, etc. D.).
3. Adaptation for different situations. "Rotband" can be used in various climatic conditions. The plaster is suitable for rooms with low and moderate humidity, but subject to additional protection, it will be suitable for rooms with high humidity. Also "Rotband" is suitable for both professional and private use.

We’ll dive into the realm of KNAUF ROTBAND in this post, examining its characteristics, special features, and the fundamental guidelines for its use. Whether you’re a seasoned pro or a do-it-yourselfer, getting the most out of your paintwork projects depends on your ability to comprehend the features and application instructions of this product. We’ll give you helpful advice on how to get the most out of KNAUF ROTBAND, from its composition to its application methods, so that you can paint successfully every time.

Specifications

The material’s primary technical parameters dictate its qualities, properties, and application process on various surfaces. A variety of characteristics, including composition, mixture shade, potential layer thickness, drying time, and many others, are typically of interest to finishes.

The form of release

The plaster "Rotband" is facing various containers made of paper and plastic bags. Although there are other packages (10 kg, 25 kg), the most common ones on sale are packages weighing 5 kg and 30 kg. Regarding Rotband’s pasty finish, it should be looked for in 5–25 kg plastic buckets. The following indicators can help you differentiate an authentic plaster from a fake:

• marking of the date and time of production with an accuracy of a second;
• the presence of a round stamp "German standard. Proven quality ”;
• the presence of embossing strips from special paper on the top layer of packaging.

Terms and storage conditions

Six months is the shelf life of the plaster in the bag with integrity preserved. During the warranty period, the material should be stored in a dry, ventilated space away from heat sources and direct sunlight, with the exception of areas with higher humidity. Keeping the material on wooden pallets is the best option. The mixture should be stored between +5 and +25 degrees for safety.

Compound

The precise makeup of the plaster is kept under wraps. It is known to contain a finely divided gypsum mixture along with chemical additives that delay the hardening process. Mineral-based ingredients are also included in the plaster’s composition to boost its elasticity, strength, and reduce shrinkage and cracking. The material is equipped with polymer additives (latex, resins, etc. D.) to enhance adhesion and fluidity.

Color

The user’s needs must be taken into consideration when choosing the mixture’s shade. White material, which is more frequently available in stores, is usually the best choice for finishing. Companies with factories in Germany, the Astrakhan region, and the Krasnodar Territory produce the white plaster mix.

Rotband is also produced in a gray version; however, the color of the band is not artificially colored; rather, it results from the characteristics of the mineral components. Plant products in G. Krasnogorsk – gray plaster. Because gypsum is mined in these areas, plastering mixtures with a pink tint are made in Chelyabinsk and Kolpino. The plaster’s tone is not mentioned on the packaging because it has no bearing on the final coating’s quality. Should the mixture’s hue be of great significance, the manufacturer can ascertain it.

The size of the fraction

The efficiency and attractiveness of plaster application are significantly influenced by the granularity of the gypsum. The fine-grained texture of all "Rotband" building mixtures is a defining feature, although the fraction’s size may vary. The manufacturer permits gypsum particles no larger than 1.2 mm. The smallest fraction of minerals (about 0.5 mm) are mined in the Chelyabinsk and Krasnogorsk fields, whereas the grain size in Kolpino is roughly 1 mm.

The final mixture is applied more effectively and lies further the thinner the plaster fraction. However, the primary purpose of the finest dispersed plasters is to produce a flawlessly smooth surface for painting or applying paper wallpaper. It is worthwhile to select a coarser-grained coating and to apply tile paste beneath the wall covering in order to execute an autonomous decorative decoration.

The thickness of the layer

The type of base affects the indicators of the minimum and maximum thickness of the plaster layer. For instance, KNAUF advises applying a layer of no more than 5 to 50 mm for wall decoration and no more than 5 to 15 mm for ceiling decoration. A layer within 10–15 mm is thought to have the best quality and consumption, but this is only achievable in the absence of significant wall plane deviations. If applying a thick layer of plaster (greater than 50 mm), you must follow this plan of action:

• application of the construction mixture "Rotband" up to 50 mm thick;
• complete drying of the finish;
• surface priming 2 times;
• applying the second layer of plaster with a thickness of 15-50 mm.

Drying time

The duration of holding and drying the solution is one of the technical features of Rotband plaster that is specified on the package. The following are the primary factors influencing the construction mixture’s solidification:

• ripening time after connecting dry powder with water-5-10 minutes;
• preservation of a liquid consistency in a container without a lid – 30 minutes;
• Drying the plaster after applying to the wall-45-60 minutes (depending on the thickness of the layer, temperature and humidity in the room);
• Complete drying of the coating before the start of finishing work – 7 days.

Strength

2.5 mPa is the plaster’s strength of compression, or its ability to withstand pressure without compromising the layer’s integrity. "Rotbanda" has a strength of 1 MPa. These indicators completely match the numbers on the package, but they are impossible to measure at home.

Plastic

Because rotband plaster is so plastic, it lends easily, fits perfectly on walls and ceilings, and doesn’t stick to tools. It easily penetrates the smallest defects and fills chips, excavations, cracks, and voids evenly. The use of premium mineral raw materials and the addition of synthetic modifiers are what give the plaster its plasticity.

Adhesion and density

The material exhibits exceptional adherence to various construction substrates, including brick, concrete, cement plaster, wood, and drywall. There are no cracks after the plaster firmly adheres to the base, and the layer does not shrink later on. Porous bases can be finished with "Rotband" if necessary, but only after initial priming. The material has densities of 730 kg/cube m in liquid form and 950 kg/cube m in frozen form, respectively.

Moisture -conducting ability

When air humidity rises, plaster can absorb more water and transfer it to porous bases. Therefore, preliminary processing of surfaces that can absorb large amounts of moisture is necessary to prevent uneven drying and lowering the quality of the finish.

Frost resistance, moisture resistance, vapor permeability

Plaster retains its primary technical characteristics even after up to 75 freezing cycles and defrosts. Additionally, it doesn’t interfere with the rooms’ natural microclimate and has outstanding vapor permeability. High humidity can cause the material to deteriorate, but with special processing, it can even be used to finish bathrooms and kitchens.

Thermal conductivity

Plaster has a thermal conductivity of 0.25 W/m, which allows it to be used to create extra wall insulation and keep the house at the ideal temperature.

Resistance to different factors

The material is sufficient to withstand low temperatures; it does not encourage open burning and does not degrade when exposed to temperature fluctuations. However, when using, pay attention to the temperature range of +5 to +30 degrees.

Consumption

The plaster consumption per square meter, as stated by the manufacturer, is 8.5 kg. Subject to the plaster layer’s approximate 1 cm thickness, this indicator is accurate. Furthermore, according to the usage instructions, a solution containing 100 kg of dry mixture yields 120 liters. A tiny stock (5–15%) must always be considered when purchasing a plaster. In actuality, problem areas receive more finishing materials than necessary for decoration.

The scope of plaster

Indoor wall and ceiling alignment is possible with plaster. It enables you to remove chips, cavities, cracks, and cracks between the plates as well as joints in the horizontal and vertical planes. Plaster allows you to prepare any surface for decorative finishes that come later.

"Rotbanda" can assist you in resolving the following issues:

• close the strokes of various purposes;
• smooth the joints between the sheets of GKL using a reinforcing tape;
• make slopes of window blocks (subject to isolation from moisture);
• increase sound and thermal insulation of housing;
• Process thin brick masonry and partitions during redevelopment.

This brand of plaster can also be used to create textured and smooth decorative coatings, various volumetric elements on the walls and ceiling, and imitation stucco molding. Dry pigments can be used to tint the construction mixture, enabling it to create different relief images and drawings.

How to work with plaster

The degree of finishing work complexity is determined by the type of finishing, the requirements for the quality of the finished coating, and the evenness of the initial surface. Wearing gloves, a respirator, glasses, and thick clothing are essential pieces of personal protective equipment when applying plaster and particularly when preparing walls. Regarding the tools, they get ready to use the Rotband:

• building level;
• kelm and spatulas;
• The rule is ordinary and trapezoidal;
• Master OK;
• grater;
• brush or roller;
• construction mixer;
• dilution capacity;
• ladder.

This brand of plaster can be applied mechanically or manually with the use of buckets and common construction tools, depending on the expertise of the operator. Lighthouses use plastering when their walls have significant irregularities.

Preparatory stage

Plastering requires first that the walls and the room be carefully prepared. In order to accomplish this, they remove all construction debris from the space, exhaust all coatings, and shield the surfaces from potential plaster damage (by covering them with cellophane or construction tape). Plastering is done right away in new buildings, and the previous finish is removed from rooms that have already undergone repairs:

• cleanse the falling plaster;
• Wipe or polish the paint;
• wash off lime;
• moisten with water and ripped off the wallpaper.

Additionally, sandpaper or a grinding machine are needed to remove the large irregularities and all of the base’s bulges. A composition designed to prevent corrosion is applied to metal components. Additionally, KNAUF or other suitable compositions produce primer. Two coats of primer are applied, separated by a day. Place gypsum beacons if necessary, spacing them 40 cm apart and aligning them with a level in a single plane.

Mixing the solution

Plaster needs to be properly diluted for a high-quality application. The manufacturer specifies the ratio in which water should be mixed with the dry powder from the bag. In order to accomplish this, the contents of a 30-kilogram pack are poured into the basin or other handy container after 18 liters of water have been added. The product is then continuously mixed with a mixer. The mixture should be mixed until all of the lumps are gone, and it should have the consistency of thick sour cream. The plaster is "matured" under the lid or film for 5 to 10 minutes, at which point it is mixed once more and prepared for application.

Experts recommend that you pour a little less liquid than what the manufacturer specifies right away. It is quite simple to dilute the mixture too much, but it can be problematic to add dry powder to an overly liquid mass. The following issues could arise if the plaster used on the walls is not the proper consistency:

• layer cracking;
• the appearance of tubercles from unreasonable lumps;
• detachment of plaster;
• Vimitation of the layer.

Application of the composition

Using a spatula or cell, plaster is thrown onto the walls, and the plaster is then smoothed with wave-like motions. When there are large bumps, plaster is applied using traditional technology in three layers:

1. Spray. Kelma put a solution between the lighthouses, leveled the rule until a layer is obtained 5-6 mm, allowed to dry.
2. Priming. The second layer of the required thickness is applied with a spatula, wiped with a half. For relatively even walls, this stage can be made by the final. For old, crumbling coatings, it is better to carry out additional reinforcement with a special net directly on the raw second layer, and then perform the third.
3. Shelter. Applied with a spatula, grinned with a construction grater. This layer is designed for the final smoothing of the base defects.

A "falcon" is positioned on the ceiling and is being moved in the direction of itself. Here, the cord between the metal beacons serves as a guide for alignment.

Cutting

About 40 minutes after the work is finished, this stage is created by applying the final or single coat of plaster. Gypsum plaster has already grabbed after the designated amount of time, but it hasn’t fully frozen yet. The metal rule of the trapezoidal shape with sharp edges works best for trimming. Its assistance makes it simple to remove any imperfections and tubercles that were still visible on the wall’s surface. Trimming is not possible if the prior stages’ work was completed to an exceptionally high standard.

Grout of plaster

Glovering plaster

This method is typically applied prior to painting walls. It looks like this: Four hours after the grout, a light mist of water is applied to the plaster, and it is again worked with a metal ironer.

Decorative design

You can use latex or acrylic paint to decorate the completed plaster layer. The coating may have a single color, several colors, stenciled designs, or an intriguing design. Additionally, there is a chance to create a relief on unfinished material. For this purpose, use trowels or other handy tools to manually draw the desired ornament on plaster using specially textured rollers, stamps, or other convenient tools. Use these decor items the most frequently:

• imitation of stone or brick;
• strips;
• Christmas trees;
• geometric figures;
• Floristic motives.

You can use special painting graters or brushes with a hard pile to achieve the structure of "Rain." Such a coating is additionally varnished or stained on top. Initially, the paint was to be applied to the wall using a regular broom or a brush that had been moistened.

Advantages and disadvantages of plaster

On a gypsum basis, rotband plaster offers several indisputable benefits:

• environmental cleanliness and complete safety for humans;
• plasticity, light distribution over the working surface;
• smooth, pleasant to the touch texture, suitability for all types of finishes;
• participation in the formation of a favorable microclimate in the house, the ability to rapid moisture absorption and moisture;
• exclusion of settlement with fungus and mold, hygiene;
• excellent sound and heat-insulating characteristics;
• high indicator of adhesion to building materials;
• beautiful aligning and decorative properties;
• low risk of shrinkage and cracking;
• moderate consumption and economy;
• quick drying, the ability to start finishing more likely;
• small mass of plaster layer.

Rotband’s drawbacks have as well. Even though the plaster is inexpensive to use, it costs a lot, especially when compared to domestic brands. Although the product is not easily cracked, it may still be shrinking in some situations. This occurs as a result of improper solution establishment and a breach of the technology used to apply the mixture. Furthermore, gypsum plasters cannot be used in unheated rooms or for exterior work without additional protection due to their poor suitability for these environments.
