Today, there are a large number of new building materials, thanks to which you can decorate your house in any style, make it beautiful and cozy. Rothband plaster (the instruction for use is written directly on the packaging) is a modern mixture that is used to process vertical and horizontal surfaces of residential and non-residential premises.
Product Feature
The presented material consists of gypsum and polymer additives that increase the quality of the mixture and provide good adhesion to the base. It is best used for processing smooth surfaces, although it can also be used for porous.
To put "Rotband" the instruction advises at a temperature from 5 to 25 degrees above zero. The thickness of the layer can be from 5 mm to 5 cm. It takes about a week to completely dry the plastered surface. The shelf life of the dry mixture is six months. The specific gravity of the Rotband is small, therefore it can be used for processing ceilings. The ripening time of the solution is 10 minutes.

Now it should be noted all the advantages of the presented product. "Rotband", the instruction for use of which contains not only characteristics, but also methods of application, has such advantages:
- Versatility.
- Ease of use (does not require any special tools or skills of a professional builder).
- Low material consumption and low weight.
- Ecological cleanliness.
- High quality mix.
- Reasonable cost.
- There is no need for additional puttying.
- Excellent decorative and adhesive qualities.
- Ensuring a smooth surface.

Application area
If you decide to purchase Rothband, the instructions will help you understand where you can use this material. Most often used indoors where humidity is at a normal level. Although there is the possibility of using this material in the kitchen and bathroom. The mortar is treated with ceilings and walls built of brick, DSP, concrete and polystyrene foam.
It is advisable to use the material for smoothing smooth surfaces, although it is permissible to use on porous substrates, which should be pre-primed. Most often, such premises are used to repair living quarters.
Features of the preparation of the solution
If for repair you already bought "Rotband" (plaster), the instructions will help to properly mix the dry mixture. It should be noted that the finished solution hardens very quickly, so it becomes unusable after 25 minutes. Therefore, do not knead it too much. Excess solution can be used to align any defects.
Like any gypsum mixture, the "Rotband" (plaster) instructions for use require stirring in a clean plastic container to a uniform thick consistency. Please note that for a standard bag of 30 kg you will need about 18 liters of water. That is, 2 parts of the liquid is mixed with 3 parts of the powder. First, water is poured into the container, and then the mixture is gradually added. Try not to mix everything at once. It is better to add a little plaster.
Use a construction mixer or a special nozzle and drill to stir. Do not turn on the appliance at too high a speed, as the solution may splatter. In order for the Knauf Rotband universal gypsum plaster to reach its standard, it will take about 6-10 minutes, after which it needs to be mixed again. After this, water, mixture or any other components cannot be added.
Checking the readiness of the solution can be very simple. To do this, put the plaster on the blade and turn it over: it should not fall. Now "Knauf Rotband" (instructions describe in detail the use of the material) can be applied to the surface to be treated.
Note that the lower the temperature of the used water, the longer it will be possible to use the solution (however, no more than half an hour).
Preparation of the basis for work
If "Rotband" (plaster) is suitable for surface decoration, the instructions for use may have instructions for preparing the base. This procedure is quite simple. You have to clean the surface of dust, debris, wallpaper, old plaster and other types of finishes.
Universal gypsum plaster "Knauf Rotband" is used to align the walls, as well as their finishing. If there are metal elements on the base, try to thoroughly clean them and treat them with a special primer. Walls, especially concrete, also need to be pre-prepared for grouting. For this, a deep penetration primer is used.
Naturally, the surface of the base must be marked.
Essential tool
In order for Knauf Rothband gypsum plaster to lie well on the surface, special tools must be used. To work, you will need this tool:
- Spatulas of different sizes (metal, plastic and rubber).
- Kelma.
- Small containers with straight sides, which will be convenient to clean with a spatula.
- Chisel and chisel.
- Measurements for water.
- Flat brush with stiff bristles.
- Grout.
- Sandpaper.
- A special tool for aligning angles.
- Building level and plumb.
- Protective clothing, glasses, gloves and a respirator.
Features of the use of material
Before plastering the walls with the Rothband, it is necessary to prepare them. If this procedure is successfully carried out, you can begin to apply the solution. Surface treatment is carried out in several stages:
- Installation of beacons (first, extreme and corner elements are fixed).
- Alignment.
- Grout surface.
Note that there should be no defects or dents in the worked out area. Alignment is performed using the rule. You can “stretch” the solution in any convenient direction. Excessive plaster should be removed.
After half an hour, the surface is smoothed and grouted. To do this, you need a sponge and water. Moisten the base with plenty of water. Next, circular movements of the sponge are made over the entire surface. Do not push too hard on her. At first, the sponge can move quite easily. If you need a glossy wall, then it must be moistened and ironed no later than 3 hours after application.
To structure the surface, use special molding tools or a relief roller. Please note that the average thickness of the plaster layer is 1 cm with a minimum of 0.5 cm.
Useful Tips
There are some points to consider when working with the mixture. For example:
1. If you decide to process the wall of foam or chipboard, then apply the plaster in 2 layers, and lay a fiberglass mesh between them.
2. Decide in advance where you will put the remaining solution.
3. After completing work, wash all tools as quickly as possible.
4. For final hardening of the material, wait at least 7 days. At the same time, the room should be ventilated, but drafts should be avoided.
5. Porous surfaces are pre-treated with a deep penetration primer.
6. If there are metal elements on the wall, clean them and paint them with a special protective mixture that will prevent rusting. Otherwise, red spots will appear on the surface that you cannot eliminate.
7. Using the "Rotband" in rooms with high humidity, the surfaces must be treated with a special waterproofing agent.
That's all the features of working with the submitted material. Good luck
