This ready-mixed plaster is a popular choice for plastering projects because it works well on a variety of surfaces.

This article will examine the composition and performance features of Rotband plaster, as well as its technical aspects. Gaining an understanding of these elements will enable you to apply it wisely and guarantee the best outcomes for your walls.

We will also give you step-by-step instructions on how to apply and prepare Rotband plaster correctly. To help you plan and budget appropriately, you’ll also find information on how much plaster you’ll need for your project.

Packaging and storage.

Three-layer paper bags weighing 30 kg are used to package Rotband plaster. They keep the mixture usable for an extended period of time by not condensing moisture. They ought to be kept on wooden pallets in low-humidity areas. Using the bag first is advised if it is open or damaged. This will stop the mixture from unnecessarily hardening. It is kept for six months in an undamaged bag.

Rotband plaster is a flexible and easy-to-use solution that is suitable for both novices and experts. This plaster is a popular option for interior walls and ceilings because of its outstanding adhesion, smooth finish, and short drying time. The secret to a successful application is paying close attention to all of the instructions, from surface preparation to finishing touches. Achieving the desired outcome requires an understanding of its technical characteristics, such as thickness and drying time. The smoother and more predictable your plastering project is, the more efficient and cost-effective it is when material consumption is calculated correctly.

Preliminary work with the base.

Cleaning from the previous coating.

Pre-dried surfaces need to be treated, and a temperature of at least +5 degrees Celsius is needed. This results in less plaster being used and in better application. Additionally, any leftover paint, wallpaper, plaster, tiles, or whitewash must be cleaned. Eliminate the base’s protrusions and irregularities. Make sure to apply an anti-corrosion liquid to metal components. If not, external corrosion might show signs of it.

Primer.

• Substrates that have increased moisture absorption must be covered with a primer. This is done in order to ensure uniform adhesion of the plaster to the base. You can prime with brushes, rollers or sprayers. According to the instructions, it is recommended to use Knauf-Grundirmittel primer.
• Surfaces that, according to their technical characteristics, do not absorb moisture, should be covered with Knauf-Betokontakt primer. This is done to increase adhesion.

Setting up beacons and corners.

With 40 centimeter gaps, apply Rotband plaster to the wall. Place the beacons in one plane by pressing them into the moldings. The leveling rule needs to be 20 centimeters longer than the beacons’ step. With beacons, the corner profiles are positioned in the same plane. The side inside the profile is where the moldings are applied. Rotband plaster, 10 mm layer consumption per square meter.

• Knauf Rotband plaster – 30 kg; consumption 8.5 kg per 1 m2.
• KNAUF-Betokontakt – 30 kg; consumption 0.3 kg per 1 m2.
• KNAUF-Grundirmittel – 30 kg; consumption 0.1 kg per 1 m2.

Using the calculator on the manufacturer KNAUF’s website, you can calculate a detailed consumption.

Sequence.

Mixing.

Fill a metal or plastic container with eighteen liters of water, then add thirty kilograms of Rotband plaster. Pour the entire contents of the bag into the water after using six spatulas to thoroughly combine everything. Using a construction mixer, thoroughly mix the mixture until all lumps are gone. The mass ought to be uniform. Increase the amount of dry plaster if the mixture is too liquid. You must wait for five to six minutes after combining everything, then stir once more. It takes time for technical characteristics to mature.

Application.

For twenty minutes, apply the mature mixture to the treated base. You have to move like a "falcon" on the ceiling, moving in your direction. Using a spatula, the surface is covered by throwing. The consumption is unaffected by this because everything is leveled later.

Note: To streamline and automate the process, if you purchased plaster for machine coating, you should utilize specific stations.

Everything is leveled with a tool after throwing, usually by moving in waves.

Apply additional layers of the coating after creating roughness on the first layer if necessary to increase its thickness. which will promote the layers’ adhesion. Only a day later can the second coating be applied. This is when Rotband plaster dries.

Alignment and grouting.

Technical characteristics state that it needs to set for 50 minutes before being leveled with a big spatula or metal rail. All irregularities are covered in order to remove the excess. Lower consumption is thus attained. An additional tool used to rub down the wall before painting or applying wallpaper is a float. They achieve this by moving in circles while heavily moistened with water; this creates an extremely smooth surface.

Creating a structure.

Should relief be required, it is simple to apply; simply roll a roller with a relief on a wheel over a pliable surface (after leveling with a rule). A trowel can also be used to create structures.

It is advised to ventilate the room in order to hasten the drying process of rotband plaster. Just allow air to pass through the windows and doors to accomplish this.

Remember that it is very difficult to remove the dried structure, so make sure to wash the used tool beforehand.

More details from personal experience.

The brand has been in our market for a while, having gained the affection and confidence of numerous builders. Its attributes are listed in the text above. Compared to its primary rivals, "Starateli," "Volma Plast plaster," and "Osnovit," it currently leads in sales. It has been produced in Russia for a long time, even though it is thought to be German. 30 kg bags are used to package Rotband plaster. These are typically stronger paper bags that hold the Rotband plaster in place. The bag comes with usage instructions.

Special properties.

Once you are comfortable with Rotband plaster and its usage instructions, you will notice that the suggested layer thickness ranges from 5 to 50 mm; however, this is not always the case. Because of their proven strength and enhanced adhesion, 1 mm layers hold very well, as demonstrated by multiple practices.

Using the calculator on the Knauf website, you can determine the consumption per square meter. The manufacturer guarantees that the three colors are due to variations in natural gypsum and have no bearing on anything. Rotband is available in pink, white, and gray hues on the market.

Nevertheless, since Rotband plaster has different technical properties, it is important to take note of them.

Applying a thick layer of white or gray Rotband causes tiny smudges to appear as horizontal waves; this does not occur when pink plaster is used. However, the instructions state that it is best to use white and gray colors to level the wall for wallpaper finishing; just lightly grout the area after finishing.

Graininess is the reason for color variation in properties; pink Rotband plaster has a fraction of 1.2 mm, while other colors have up to 0.5 mm. The instructions don’t specify this. The compositions are consumed roughly in the same amounts at the same time.

Thus, when making a purchase, keep this in mind. Sadly, the packaging itself contains no information regarding color. Its manufacturer can be used to identify it (there are several factories).

• White Rotband is produced by Knauf Gips Baskunchak CJSC, Knauf Gips Kuban LLC
• Grey Rotband – Knauf Gips LLC
• Pink Rotband – Knauf Gips Kolpino LLC, Knauf Gips Chelyabinsk LLC

Preparing the solution and how long it dries.

Recall that Rotband plaster, when diluted with water and left for no longer than 20 minutes, dries in accordance with technical specifications. As a result, avoid diluting a big volume of solution all at once. Decide ahead of time on a 20-minute work volume to avoid wasting your money. Once the volume has been determined, you must choose a mixing vessel, ideally one that is angularity-free.

If not, the mixture won’t blend entirely. A basic bucket is the most straightforward and practical choice. With additional mechanical tools, you can mix manually or mechanically.

Fill the container with water using the ratios specified in the Rotband plaster bag instructions. Three parts mixture to two parts water. Under-adding is preferable to over-adding because you can always add more. The setting time will be extended if you use cold water.

Using a construction mixer, mix the mixture until it has the consistency of thick sour cream. The trowel turned down should not cause it to flow downward. It proved to be too thin? No issue, just add more dried plaster. After five minutes of waiting for the solution to fully mature, stir it once more.

Important: It is not advised to mix dry plaster or water with the completed, mature solution. Peeling may result from this and cause a decline in quality.

Necessary tool.

Plastering takes a lot of work to complete. Apart from the actual application, there’s also the surface preparation, which frequently calls for the use of force. removing lumps and humps from a concrete base or bricks using hammers and chisels. Sanding may be required using sandpaper. Safety is therefore of utmost importance. Obtain a respirator, gloves, and construction glasses.

Important: Even though the bumps may seem complicated, it is best to remove them all. If you don’t, you will need to add a few millimeters to the entire area, which will increase the amount of plaster used.

Once the paint or wallpaper has been removed from the base, you must assess how evenly the treated area is spread. Use a building level or a homemade plumb line (a thread with a weight at the bottom) to accomplish this, per the instructions. You can use a nail to fasten it on top. Make sure the thread is tied so it stays out of the application area. Then just use a ruler to measure the distances at various locations.

Hand tools, such as trowels and various-sized spatulas, are used for covering and leveling surfaces. The rule is applied to beacons. Applications can be mechanized in addition to being applied manually. To finally level it, you’ll need a grout once the solution has been applied completely and dried. having readyed the area for additional wallpaper or plaster finishing work.

Alignment with beacons.

Using its indicators, we positioned beacons. You’ll be able to get a perfectly level wall later on thanks to this. It is recommended, per the instructions, to use T-shaped beacon profiles if the walls are made of concrete or brick and have not been plastered.

Use Rotband "Knauf" gypsum plaster to secure them; due to its unique technical properties, it can support small weights. Simply place the solution where the beacon will be. It only takes 3–4 points of contact. Make sure you install it without touching the exposed thread.

Important: in order to strengthen the base and enhance Rotband adhesion, you must first coat the wall with a specific primer.

Naturally, leveling takes place following plaster application. The Rule tool is utilized in this instance (the letter "i" is emphasized). You must slide the rule over the beacons from bottom to top after spreading a layer of Rotband between them. This will remove any excess mortar and distribute it over less saturated areas. Once the surface has been leveled, take the beacons out and move them to the following area. A trowel can be used to level the beacon’s remaining groove with ease.

Alignment with grout.

After finishing the procedure, you must move on to the next crucial step, grouting. It is best to do this as soon as possible to avoid any more problems when adhering the wallpaper later on.

You will need to use fine dispersion putty to level the plaster further if you choose not to grout.

After coating, Rotband "Knauf" gypsum plaster is rubbed for 40–50 minutes. when the resolution becomes challenging.

Spray the wall liberally with the grout that has been dampened with water. Using the grout on the plane, move it in circles without applying pressure. A "milk" of Rotband will eventually form, aiding in the removal of any remaining unevenness from trowels and spatulas.

Movement will be far more difficult due to the increased viscosity of the structure. However, overall effort will not be significantly expended. Once the grout has been removed from the wall, take out the "milk" from the tool and move on to another location.
