Invalid selection of material for repairing walls is able to beat off the desire to continue work and lead to unsatisfactory results. That this does not happen, it is worth paying attention to special plaster plaster for interior decoration.
Is it worth afraid of uneven walls and how to cope with them? The answer is obvious - of course not. In this article, I will tell you how to spend the alignment of the walls by Rotband with your own hands and get the result is no worse than the pros.
Why do we choose Rotband?
The alignment of the walls was always a terrible and complex process for beginners. Indeed, without having sufficient experience, working with various solutions, especially cement is quite difficult because of their properties. But is it possible to be a reason not to take the alignment at all? Especially to solve this problem there is a special plaster called Rotband. It is produced using the technologies of the German company Knauff, so you will always see this word on the packaging.
What is the feature of this gypsum plaster? The fact is that it has all the physical properties that make it use as simple as possible. This plastic plaster, easy to apply with a small drying period. Therefore, even newcomers can spend the alignment of the walls by Rotband without much effort and even with pleasure. Rotband layer is applied with a layer from 5 to 10 mm, but it is recommended to withstand a layer with a thickness of about 10 mm, which dries in 45-60 minutes. Although practice shows that even 1 mM plaster holds tight enough.
The color of the plaster can be white, gray and pink. This plays a role not only in aesthetic plan, but in functional. White and gray plaster less grainy, not more than 0.5mm, so when applied, small waves horizontally forms. This feature is easily eliminated by subsequent grout. Pink color is characterized by a larger graininess - up to 1.2 mm and the appearance of waves in this case is not observed.
Color can be determined by the manufacturer or clarify the seller, since it is not specified on the package. White mixes are produced by CNAUF Gyps Baskunchak CJSC and Baskunchak Knauf Gypsum Kuban LLC, gray - Knauf Gypsum LLC, and Pink - Knauf Gyps Kolpino LLC and Knauf Gyps Chelyabinsk LLC. All these are the production of Russia. However, there are, of course, exceptions. Therefore, with the importance of color, it is better to clarify it to purchase. Packing exists in bags of 5, 10 and 30 kg.

Where to start alignment?
Preparation of walls
Alignment of the walls of the Rotband is invariably begins with their preparation. To do this, it is necessary to remove the entire former finish from the walls. Wallpaper to disrupt, blur, paint, old stucco, and pull out all old nails and screws. Speakers are better to cut, otherwise you will have to use a large number of plaster and it will complicate work significantly. Then it is necessary to dream all dust from the wall. Such work is quite time-consuming and not always safe, so I advise you to be extremely attentive and careful. This is especially true of the use of tools, such as a hammer, chisel, spatula. It is also better to use a respirator and a headdress.
After complete cleaning of the walls, they must be carefully projected. This significantly increases adhesion, strengthens the surface and protects it from external influences. When the wall is cleaned and primed, you can go to alignment.
Alignment
To do this, appreciate all its irregularities. Check vertical and horizontal. For the first you need a plumb, and for the second construction level.
With the help of a plumbing, you can easily install beacons that are attached to a small number of plaster or mounted using self-tapping screws. Lighthouses are better installed every 30-40 cm. The horizontal is stretched by a cord or thread, which should come close through all the lighthouses, pressing them as much as possible. To secure the cord, in the angle of the room you need to drive the nail and tie a thread on it. Sometimes they use screws, but I do not advise you to do this, as in this case you will be very difficult to move the cord, exposing it to the desired thickness.
I also want to recall the evaluation of diagonals. This is a moment that is often ignored, getting not completely desired result. If necessary, the grid is tightened to the wall. It is important to do in areas with cracks or under a large layer of stucco apparent.

How to prepare a mixture
So, everything is ready for the beginning of work. It remains to prepare a mixture and armed with tools.
I want to remind you about the rapid grasp of Rotband, in connection with the life of the solution usually does not exceed 25 minutes. Therefore, it is necessary to knead the mixture in a little to have time to work out.
I advise you to immediately decide on the sites that can be applied. It is more convenient to knead the mixture in container with rounded corners. Ideal for this is a plastic bucket. It is poured clean water and then a dry mixture is added in proportion 2: 3.
But it is better to use a deliberately smaller amount of dry plaster and, if necessary, add it at the end. And then there is a nuance. Your solution will live longer if used cold water. The mixture on the consistency should be such that it does not fall from an inverted trowel. You can easily and easily mix the plaster with water using an electric drill and a mixer nozzle. After that, the solution matures within 5 minutes and is mixed again. Now it is impossible to add or dry the mixture into it. Having finished cooking, you need to very quickly wash the mixer with water or another tool used, since the rotband is instantly grasped and frozen. Otherwise, clean the tool will be problematic.
Application on the wall
Tool
In order not to distract anything from work, which should pass quickly due to the high speed of solidification of the solution, it is better to prepare the entire necessary tool in advance. You will need spatulas, Kelma, corner equalizers, rule and ironing. A wet rag and a wide brush come from auxiliary tools so that the contamination can be eliminated.Closeing in Vpadin
First you need to close all the depressions. To do this, apply a small amount of solution to these sites and then swipe from one end of the depression to another. This will allow you easier and faster to cope with further alignment. To the wall and the Rotband cloudy more successfully, it is best to apply it to its thin layer on the entire surface. This can be done using Colel. After drying the first auxiliary layer, you can proceed to apply the main one if it should not be too thick. Otherwise, this process is broken into two stages. Rotband application technique is shown in many videos. I recommend to get acquainted with them in advance.

To align the wall, you will need to sample a solution on the wall to the area between the beacons, and then, setting the rule into two adjacent lighthouse, inserted the movement along the wall at an angle of 45 degrees. Such an angle of inclination will allow excessions of the plaster smoothly for the maximum area. As a rule, you can use special construction or any rigid rack with a length of 0.5-2 meters, depending on the width of the lighthouses. After several such postings, the rule must be wiped with a damp cloth. If this is not done in time, then the surplus of the plasters remaining on it dry, and very much interfere with further alignment.
If waves appear in the process of work, this suggests that the surface is smooth and they can simply be eliminated by ironing. Unlike cement solutions, in the case of the Rotband, the rule can be moved in all directions, not limited to the bottom-up option. Leveling the wall is better small areas, remembering the short period of life of the solution.

About how to put the walls of the Rotband, look in the video belowIn conclusion - grinding
If after the completion of work, do not see the perfectly smooth surface before you, I want to calm you. It is absolutely normal. Until complete finishes, you remained only one step. Waves, furrows and drops need to be stabbed.
This procedure is starting after applying. By this time, Rotband dries completely and after touching him, there is no dents. All dried drops are cut off with a spatula. Then the wall section is wetted with water with a brush and rubbing the grouting circular motions. As soon as this process becomes difficult, remove the grip and look at the wall. All pits and furrows will be obvious, and the rest of the surface is smooth with small waves.
Surplus Rotband, which remained on the grout in a very liquid form, remove the spatula and apply to the furrows. Then it is necessary to carry out the spatula along the same site, pressing it in parallel to the surface. If necessary, to carry out the procedure with the grout again. Thus, pass throughout the wall and get a flat surface, which is suitable for further finishes.
