How to plaster walls with Rotband

In order to create a smooth, long-lasting surface that is prepared for painting or wallpapering, plastering is an essential step. Rotband is a highly preferred plastering material due to its user-friendly nature and superior performance, particularly when applied to interior walls.

Whether you’re building a new structure or remodeling an existing one, using Rotband plaster correctly can make all the difference. This adaptable plaster made of gypsum is made to stick well to a variety of surfaces, providing professionals and novices alike with a dependable choice for superior wall finishes.

We’ll walk you through every step of plastering walls with Rotband in this post, from surface preparation to applying the last coat. You can guarantee a consistent, flawless finish that will last for many years by following these instructions.

Rotband plastering is an easy method for both novices and experts alike, providing a smooth, long-lasting finish. This guide will take you through all the necessary steps to ensure a professional-quality outcome for your home renovation projects, from priming the wall surface to applying and finishing the plaster.

Characteristics of Rotband

Cement-sand, lime-sand, and cement-lime-sand mixtures are the most common materials used for plastering walls (see Cement-sand plaster: features of the material). One of the many drawbacks of all of them is the development of cracks.

Working with such mixtures requires a lot of effort and energy because of their low technological value and weak plasticity:

  • Traditional mixtures have been replaced by gypsum-based solutions (see. Dry gypsum plaster mix: features of use). Modern compositions are more flexible, do not crack and do not shrink. They are so easy to use that even a novice craftsman can work with them.
  • A bag of "rotband", weighing 30 kg, costs about 180 rubles. This amount of plaster can be used to treat about 3.5 square meters of walls, applying a layer about 1 cm thick.
  • Gypsum-based plasters have a lower density, compared to cement, which reduces the load on the entire structure as a whole. In addition, they harden earlier than cement, reducing the time of construction work.
  • Working with "rotband" is more convenient and faster: when applying a layer about 2 cm thick, the plasterer can process up to 15 square meters of surface, and when using a conventional solution – no more than 10 square meters.

Application of plaster

Using the Rotband plastering walls video, you can complete the task on your own. Applying a cement composition is the same as this. Simply put, the surface is more even. The fraction is smaller.

Start of work: surface preparation

Plastering should be done at a temperature of between +18 and +22°C and a relative humidity of about 60%. Plaster is applied to a dry surface that has been cleared of debris and dust on Rotband. There should be notches on this concrete base, if that is the case.

  • The surface is cleaned of dust, dirt, traces of paint, as well as greasy stains and covered with a deep penetrating primer.
  • After the primer has dried, you can set up beacons (see. Installing beacons for plaster without problems). Metal profiles are used as beacons, which are set strictly vertically and in one plane. In the future, the beacons will serve as a support for the rule.
  • Metal beacons have good strength, they are easy to install, but this increases the consumption of plaster mixture by 1.5 times. When buying beacons, you should pay attention to their evenness. Sometimes retail outlets do not pay special attention to the transportation process, as a result of which, beacons may become deformed.
  • The process of installing beacons does not tolerate haste, since this greatly affects the quality of the final result.
  • The main task of the master is to set the beacons as evenly as possible. For this purpose, you can use a building level and a long rail. You can easily use a rule with a vertical and horizontal level indicator. Its length should be 10 centimeters less than the length of the beacons. Beacons are set vertically with a step of 1 to 1.5 meters.
  • Metal beacons are installed on plaster cakes made of "rotband". The plasticity of the cakes allows them to be set strictly vertically and evenly using a rule. For this, the rule is attached to the lighthouse and pressing it against the wall, control evenness and verticality.
  • The gaps between the wall and the beacon should be filled with plaster mortar, while it is advisable to remove excess mortar.
  • If the walls have large irregularities, then before installing the beacons, the surface should be leveled, especially in the places where the beacons are installed. To do this, from bottom to top, at the place where the beacon is installed, the plaster mixture is applied in a small strip, about 50 mm wide. Beacons are installed after the strip has set well.
  • If the length of the aluminum rule exceeds 2 meters, then beacons can be installed in increments of 1.5-1.8 meters.
  • For walls up to 4 meters long, it is enough to install 3 beacons, while the outer beacons are installed at a distance of about 20 cm from the corner of the wall.

Note: Using the beacon installation technology described here, walls can be made perfectly level with an error of less than 0.5 cm, meeting international standards.

Preparation of plaster

These mixtures are essentially made in dry form and packed in 30 or 50 kg bags.

  • In order for the mixture to be applied to the surface, it must be diluted with water and mixed well until a homogeneous mass is obtained, the consistency of which resembles sour cream.
  • To do this, take a plastic bucket with a capacity of 10-15 liters and fill it with water to 1/3 of the capacity.
  • After this, the dry mixture is added to the water and thoroughly mixed with an electric drill with an attachment. There should be no lumps in the finished mixture, otherwise it will be difficult to work with it. After this, the mixture is allowed to stand for 10 minutes.

Note: Using a drill with an attachment is the best option for mixing because it will ensure homogeneous mass and speed up the process.

Applying plaster

Applying the plaster solution from bottom to top on a sanitized, sturdy surface calls for a wide spatula. It can be thrown onto the walls if you possess the necessary abilities, particularly if you need to apply a thick layer.

  • For one entry, mixed with plaster, the space between the beacons is filled. In this case, it is advisable to use the entire solution at once, after which, using a rule or a flat lath, resting against the beacons, the solution is pulled from the bottom up, simultaneously making a movement left and right. Excess plaster is raked off with a rule, leaving behind a perfectly flat surface. Excess plaster can be thrown into the gaps between the beacons.
  • After filling one span between the beacons, move on to another and so on until the wall is completely plastered.
  • Rotband plaster is very flexible, so you need to make sure that it does not float under its own weight. This can happen if there is a significant layer. Having noticed that the plaster has begun to float, you need to return to the previous place and tighten it with a rule.
  • After 40-60 minutes, you can begin to smooth the surface. The fact is that in the process of "tightening" small defects are possible that should be smoothed out. To do this, the plaster solution is mixed again and using the trowel or spatula, this solution is applied to the still not dried surface and smoothed out.

It should always be kept in mind that further work cannot be done until the plaster layer has dried completely. It will take approximately 6-7 days for the "rotband" plaster to fully dry with a layer thickness of about 2 cm.

Additional operations

Dark, thick wallpaper can be adhered to walls that have been well-smoothed. It is very undesirable for the wall’s base to show through when gluing thin or light wallpaper. The answer to the question of whether it is possible to plaster with rotband in the bathroom is usually in the affirmative.

Note: Two layers of finishing putty should be applied over the plaster layer, and high-quality polishing should be completed in order to avoid taking any chances and bring the walls to their logical conclusion.

Every building has both exterior and interior corners. Things with the outer angles are a little different, particularly if they are in the area of intense movement, if there are no issues with the inner angles. These edges require security.

  • This can be done if metal corners are installed on the outer corners during the puttying work. If the corners are installed correctly, they will serve not only as protection, but also as a kind of beacons that will simplify the process of forming the outer corner. To install them correctly, you can use the same technology as when installing beacons.
  • If you plan to lay ceramic tiles on the plastered surface (see. Ceramic tiling: a job that anyone can handle), then there is no point in carrying out additional operations. The tiles can be laid directly on the plastered surface.

What is a reinforcing mesh

It is advisable to lay a fiberglass reinforcing mesh with 2×2 or 5×5 mm cells on the walls when they are getting ready to be painted. Putty is used to lay it over the base. After that, you’ll have a better-quality plane and find it much simpler to adhere wallpaper to Rotband plaster.

  • The advantage of the mesh is that it will not allow the surface to crack.
  • In addition, during its installation, the walls are slightly leveled if they had serious flaws. Laying the reinforcing mesh on weak uneven surfaces is especially relevant, as it makes the walls stronger.
  • The mesh is laid from top to bottom, with an overlap of about 10 mm. It must be applied to all installed corners with an overlap of 10-15 mm, which eliminates the possibility of cracks appearing at the border of different materials.
  • The reinforcing mesh can be installed on PVA glue. To do this, PVA glue is diluted with water in a ratio of 1:4, after which the work surface is covered with this solution using a roller with a long pile. The mesh is laid from top to bottom and pressed against the wall with a wide spatula. During the grinding process, excess glue is removed, and the surface is finally rolled with a dry roller.
  • After complete drying, 2 layers of finishing putty are applied to the surface, after which it is allowed to dry. After this, the surface is carefully sanded with fine sandpaper and primed with a deep penetrating primer.
  • After such careful preparation, the surface is ready to be painted with any paint, to apply Venetian plaster to such a surface, to glue any type of wallpaper or to cover the surface with any decorative materials.
Step Description
1. Surface Preparation Clean the wall, remove dust and loose particles, and apply a primer for better adhesion.
2. Mixing Rotband Mix the Rotband plaster with water until smooth, following the instructions on the package.
3. Applying Plaster Use a trowel to apply the plaster to the wall in thin, even layers.
4. Leveling Level the plaster with a straightedge or a trowel to ensure a smooth surface.
