Gypsum plaster rotband instructions for use

A popular option for both professionals and do-it-yourselfers is gypsum plaster Rotband. It is renowned for being adaptable and simple to use, which makes it appropriate for a variety of interior wall and ceiling applications.

We’ll walk you through every step of applying Rotband plaster in this guide, from surface preparation to producing a smooth, long-lasting finish. These guidelines will assist you in completing the task correctly, whether you’re working on a remodeling project or simply tidying up a space.

Let’s examine the essential procedures and advice for using Rotband plaster so that you can achieve the greatest outcomes.

Step	Instructions
1	Prepare the surface by cleaning it from dust, dirt, and loose particles.
2	Mix the plaster by adding the dry mix to water, stirring until a smooth, lump-free consistency is achieved.
3	Apply the first layer of plaster with a trowel, spreading it evenly across the surface.
4	Level the plaster using a straight edge, removing excess material.
5	Allow the plaster to set slightly, then smooth it out with a trowel or float for a fine finish.
6	Let the plaster dry completely before painting or applying any further finishes.

What is rotband

In the last century, the Knauf company, one of the oldest in Europe to produce gypsum powders for the building industry, became proficient in producing dry mixes (SS) meant for wall plastering.

The mixture also includes modifying additives in addition to gypsum, which helps the solution stick to the base more firmly and become more plastic without setting for a longer period of time.

Practical Germans started to use a red ribbon as a brand symbol on the new product’s packaging. As a result, they gave the CC itself the name RotBand, which translates to "red ribbon" from German.

The rotband-marked gypsum plaster is a material that works well everywhere. Appropriate for a wide range of bases, as well as leveling walls in spaces with momentarily rising humidity levels as well as dry rooms and indoor environments.

In the latter scenario, a moisture-resistant coating must be applied to the plaster. On a glazed loggia or veranda, you can use Rotband to level the wall because the coating is guaranteed to withstand 75 freezing cycles without losing strength.

Due to its high adherence, Knauf Rotband works particularly well when applied manually on surfaces such as ceilings and dense concrete, where other compositions don’t work as well. Applying the mass in a single layer up to 50 mm thick to vertical surfaces is made possible by the composition’s tenacity and strength.

Due to its high plasticity, the plaster mass is simple to prepare and apply, even in difficult-to-reach places. Plasterers are more productive as a result, and weariness is decreased.

Additional benefits consist of:

• ease of processing;
• non-flammability;
• the ability of the created coating to maintain a microclimate;
• the ability to achieve a smooth surface suitable for painting by simple processing.

Plastering walls with Rotband requires following the guidelines created by the company’s experts if you want the coating to be strong and last for a long time. There are directions on the packaging.

Rotband: step-by-step instructions for use for beginners

When using Rotband plaster in a room, the plastering sequence is as follows: the usage instructions provide a comparable workflow for other plaster compositions.

The steps taken to finish plastering the entire room are as follows:

• plastering the ceiling;
• processing and leveling the walls;
• finishing slopes, columns.

We will then go over each step of plastering with Rotband in detail.

Preparation of the base

Regardless of how new the walls are, the base’s surface must be ready for plastering because conditions must be met in order for two materials to connect strongly. The removal of biological stains is the second objective of preparation, shielding the plaster coating from future growth of rot, mold, or fungus. Furthermore, rust removal gets rid of brown stains that show through the layers of finishing.

In the preparatory stage, strengthening the fragile surface layer and fixing flaws are additional tasks. Furthermore, if the base is porous, open pores will remove the water that the solution needs to plaster, interfering with the plaster’s hardening processes. For this reason, sealing the pores is necessary before beginning work.

Plaster, paint, wallpaper, and peeling, old, useless plaster are being removed from the walls of the room that is being renovated. Deep potholes and cracks that result are filled in. Take off old metal hooks, screws, and nails from the walls.

If hardware must be left in place, it should be painted or otherwise insulated to stop rusting. Any biotic growth, rust, grease, soot, or efflorescence stains are eliminated.

In a newly constructed building, planning is also required. Brickwork seams are embroidered and deepened to a centimeter. Steel brushes are used to scrape the brick’s surface. Grease traces are eliminated from the concrete, and smooth walls are given notches. Large protrusions and nodules are removed. Screw heads are deepened and chamfers are cut at the joints where plasterboard sheets join. They are covered, and a serpyanka is applied to the joints in preparation for plastering.

Primer

Make sure the base is dry and free of dust before applying primer. The outcome of all ensuing work is dependent upon selecting the appropriate Rotband Knauf primer.

The brands of primers used for various substrates are listed in the instructions:

• easily absorbing water (cellular or expanded clay concrete, cement-lime plasters, brickwork) – primed with Tiefengrun or Mittelgrunt (dries in 6 hours);
• Dense materials that do not absorb moisture (concrete, polystyrene foam, cement plasters, tongue-and-groove slabs) – treated with Betonkontakt, dried for 12 hours.

Mittelgrunt (Knauf-Multigrunt can be used in its place; the primer manual provides the dilution ratios).

Displaying beacons and corners

In order to smooth out the wall’s surface, which has very minor variations, beacons are not necessary. Beacons are used to establish landmarks in situations where walls are disorganized or have surfaces with significant variations.

Prior to use, the location of the auxiliary plane, the most protruding points, and the weight of the ceiling and wall surfaces are all determined. Using a solution, a mark (plaster) is made on the site that is at least 5 mm thick. By installing the bars, it provides them with guidance. Our website has a comprehensive article about installing beacons.

Besides beacons, profile corners are fixed on projecting corners and positioned in the same plane as the beacon strips on the walls next to them.

Preparation of the solution

There isn’t much information in the usage instructions about how to prepare rotband plaster. Just four lines, which newcomers might not fully understand. As a result, we outline the procedure in reverse order.

One (30 kg) package needs to be diluted, so first prepare a clean plastic container (make sure there are no remnants of the previous mix left, too) and fill it with 17 liters of water. Thus, one liter of water is kept aside from the eighteen liters that the instructions specify. This is in case the final solution turns out to be excessively thick.

In the latter scenario, liquid is added to adjust the density after mixing. The number of plasterers working to apply and level the mixture on the wall determines the vessel’s capacity. If plastering is done by one person, then a 90-liter container will hold enough material to be used completely before it begins to set (approximately 20 to 25 minutes after mixing).

After opening the bag and using a dry trowel to scoop up the powder, place eight to ten portions into the water and start blending the mixture with a mixer.

It will take a few minutes to create a solution by mixing a small amount of powder. Additives seep into the water during this period, assisting in ensuring that the next chemical reaction proceeds as intended.

Pour the remaining material into the bag gradually after that. Continue stirring while doing this, then leave the solution and let it stand for five to seven minutes. Finally, stir and add water if needed. Add dry powder from a different package if the mortar mass is too liquid. Of course, this mixture should not have the stored water added to it. SS can no longer be added to the mass after the second mixing, at which point it is used for plastering.

Pulling and leveling

The application of the solution is analogous to that of cement compositions. Use a wide half-grater or a spatula fitted with a wide shovel. Pour the mixture into the spaces between each beacon. After filling a meter or so in length, the solution is leveled using an H-shaped rule along the beacons.

Plaster is applied in two layers if the thickness of the leveling coating exceeds 15 mm. In parallel, the initial marking is applied, and the surface is "combed" by using combs to cover it (a spatula fitted with a comb is used for this purpose). Apply the next layer, which is leveled along the beacons, a day later (not earlier), once the applied mass has solidified.

The application guidelines state that you can only apply a second layer over a freshly laid one if you haven’t had a chance to wait another half hour after you started. The layer is given a day to solidify if they are unable to meet this deadline.

The tool bar is guided with tiny zigzags across the longitudinal line to align, based on the beacons’ edges. Using a spatula, remove the solution that has accumulated on the rule and move it to the unfilled areas. It is required to be done once or twice more. They then keep filling the gap between the beacons after that.

The "dawn angle" is preserved by plastering the slopes. Plastering the top should come first, followed by the sides in the proper order. You can use a wide spatula, a cut (short) rule, or a specially designed tool for leveling.

Approximately 45–60 minutes after mixing, the applied solution’s condition is assessed by pressing with a finger. If the set dough does not stick to your fingers, use a wide spatula or a trapezoidal rule to cut off the protrusions. This is done with a "kantenhobel" (plane) on slopes.

This leaves you with a finish that has tiny (up to 3 mm) imperfections such as burrs, scratches, and tool traces, along with drips up to 2 mm. This grade of rough finishing is appropriate for both gluing tiles and decorative plaster (with a filler fraction greater than 2 mm).

Second tightening and leveling

Wait 15 to 20 minutes after the initial trimming to complete the second trimming if you want a higher-quality surface. Uneven surfaces are removed with a wide spatula.

Removing beacons and sealing grooves

After the mortar mass has solidified and pulling out metal components won’t cause the mortar to slide, the beacon profiles are removed. Using a chisel, clean the area near the end to remove the strips. Using pliers, clamp the beacon’s edge and remove it from the wall.

A groove is created on the wall following the removal of the profile. It is cleaned of dust, and the groove’s interior as well as the surrounding areas are primed. After that, add mortar to it and level it flush with the wall using a wide spatula.

Grouting the plaster

Grouting the Rotband plaster, which is done 15 to 20 minutes after the second trimming, gives the plaster a unique smoothness. Use a sponge float (you can also use a felt one) to thoroughly wet the plaster coating.

Level the marks made by the rule or spatula by moving the float in a circle. Allow the solution to absorb moisture, as evidenced by the wall taking on a matte appearance, and then use a spatula to smooth it out. This produces a high-quality surface that can be used to apply textured paint, glue down structural wallpaper, or create decorative plastering with finely detailed compositions.

We will remove the gypsum milk from the top layer if we wet the wall with a sponge once more in a span of 2.5 hours (or within a day). It will fill the remaining pores with the help of the trowel. This lays the groundwork for applying matte paint to the wall to achieve a Venetian look.

There are a few easy steps you must take when using Gypsum Plaster Rotband in order to get a smooth, long-lasting finish on your walls. When applied correctly, this adaptable plaster offers strong adhesion and a fine, even texture, making it perfect for a range of surfaces. To achieve the best results, prepare the wall, mix the plaster to the proper consistency, apply it evenly, and give it enough time to dry. A professional finish that lasts will be guaranteed with the right technique and attention to detail.

Creating a structure (if necessary)

Finely ground gypsum board Rotband is a good material to use when making patterns in relief on the wall. With your hands, you can make a one-of-a-kind decoration because the gypsum composition is safe for skin contact. Gypsum plaster can be used experimentally to achieve a variety of effects. If you want to alter the interior decor, utilize the formation techniques—a detailed explanation of which can be found in the section on decorative plasters.

Use a relief roller or any other molding tool (hard brush, trowel, brush, crumpled plastic bag, figured spatula) to create a pattern after leveling the mass with a rule. The painted ceiling is adorned once the mixture has fully dried and hardened.

Features of plastering the ceiling with Rotband

Finishing the ceiling and using your hands to level the walls with Rotband differ in a few ways:

1. If you can apply a layer of up to 50 mm to the wall with Rotband, then you can apply a layer of up to 15 mm to the ceiling. Therefore, if the height difference on the ceiling is more than 30 mm, it is pointless to plaster it for leveling. You need to use other means, for example, plasterboard.
2. If during the leveling of the walls the movement of the tool when applying the plaster mass is directed from the bottom up, then when plastering the ceiling it is directed towards itself.
3. After plastering and smoothing, the gypsum thickness along the perimeter of the ceiling (without gaps) is cut to the base with a “shtukzege” saw. The use of such a design technique prevents the formation and development of shrinkage cracks, which otherwise can originate near the walls, developing towards the center of the ceiling.

We recommend watching the videos, rephrasing the statement "it is better to see once…" to "it is better to see and hear once."

Necessary tool

Get the required tool ready before starting work:

• H-shaped and trapezoidal rule;
• wide spatula;
• corner spatulas;
• trowel;
• level and other devices for installing beacons;
• mixer;
• half-grater;
• trowel;
• rollers (for priming and applying a pattern);
• brushes;
• sponge or felt grater;
• container (90/200 l);
• masking tape;
• cord, plumb line;
• clean rags.

A feature of the equipment used to work with gypsum mass is that stainless steel trowels and metal spatula blades are required. Use of rusty steel tools will leave black marks on the wall.

When done correctly, applying gypsum plaster Rotband is a simple process that yields excellent results. It’s a multipurpose product that applies smoothly and robustly to a variety of surfaces.

A few tools and careful mixing and application techniques are all that are needed to create walls of professional caliber for anyone. The secret is to pay close attention to the manufacturer’s instructions to ensure the proper consistency and drying times.

Plastering is now easier for everyone, thanks to Rotband, regardless of experience level. You can improve your abilities and get the ideal wall finish with practice.
