It is impossible to imagine a major overhaul of premises without leveling the internal walls. For these purposes, sheets of gypsum board are often used, but recently a worthy alternative has appeared to this material - plaster "Volma. Layer". This product recently appeared on our market, but has already won the sympathy of many consumers. What its features, what qualities it has, where it can be used and how to apply, we will consider in our article.
Description of the material
Plaster "Volma. Layer "is represented on the market in the form of a white powder mixture, the main component of which is gypsum. In addition, the composition of the material includes various polymer additives that provide excellent adhesion to the substrate, impact resistance and resistance to moisture.
The product is designed for manual finishing of walls in rooms where a stable microclimate prevails. Plaster of this type is suitable for application to walls and ceiling. The composition is available for sale in packages of 5, 15, 25 and 30 kg.
Its popularity is "Volma. Layer "acquired due to a number of positive qualities. Namely:
- Ease of application. The plasticizers that make up the mixture make it easy to apply, so you do not have to make any special efforts during the work.
- No shrinkage. Unlike similar means for leveling walls, plaster "Volma" can be applied with one large layer (up to 6 cm).
- Ecological compatibility. The manufacturing company does not use harmful components for manufacturing its products, as stated on the packaging of the material.
- No need to putty the walls. Stucco "Volma. Layer "can be applied directly to the walls, without pre-treatment. After the solution has dried, the surface also does not need to be covered with a layer of finishing putty, since the plaster has an attractive glossy appearance.
- Excellent vapor permeability. Mixtures of this manufacturer "breathe", which has a beneficial effect on the internal microclimate of the premises.
The gypsum mixture "Volma. Layer ": technical characteristics of the material
Choosing this or that finishing material, it is necessary to stop on its basic parameters. At the plaster "Volma" they are as follows:
- for the treatment of one m² of the surface, 8 to 9 kg of dry mixture is required (depending on the thickness of the layer);
- the optimum thickness of the applied layer is 5-30 mm;
- the maximum permissible layer thickness is 60 mm;
- complete drying of the surface occurs 6-8 days after application;
- 1 kg of dry matter requires 600 to 650 ml of liquid;
- plaster can be applied on surfaces, the temperature of which is in the range from +5 to +30 degrees;
- primary setting of the solution occurs 45 minutes after application;
- the compressive strength index is 3.5 MPa;
- the strength of the surface for bending is 1.5 MPa.
In addition to all of the above, you should know one more nuance, which is important to take into account when starting to work with the composition "Volma. Layer". Technical characteristics of the material indicate that the finished solution is suitable for 45 minutes, but experts say that it is better not to leave the diluted mixture for more than 30 minutes.
Scope of application
This composition is used for both small and global works. The scope of the material is limited only by the fact that its main component absorbs moisture very much, therefore it is not recommended to use the composition on the street and in damp areas.
The most common plaster is gypsum "Volma. Layer "is used for the following works:
- when restoring and removing small surface defects;
- in small repairs for leveling walls and ceilings;
- at primary and capital leveling of surfaces;
- as the finish of the walls;
- for the creation of various decorative elements of the interior (arches, moldings, sculptures, etc.).
How to prepare the surface for application of the formulation
Now let's look at how easy the mix is "Volma. Layer". The manufacturer's instruction says that before the plastering, no pre-treatment of the walls is required, nevertheless a little attention should be paid to the surfaces to be treated.
To get a decent result you will need:
- Remove dirt, dust and other debris from the walls, which will interfere with the work.
- If the walls were painted or plastered, the old finish must be completely removed.
- If the surface has deep cracks, chips and other defects, they are removed and covered with putty.
- If the walls are heavily curved and a thick layer of plaster is to be applied, beacons should be installed from the profile.
- All metal objects located on the surface of the base are treated with anticorrosive compounds.
How to build a dry mixture
To prepare the working composition, use only plastic buckets or other containers. First of all, pour clean water into the bucket (at the rate of 600 ml per kg), and then dry out the "Volma. Layer". The gypsum mixture is kneaded to uniformity with a drill or special mixer.
Note that it is not worth mixing a large amount of the mixture at once, as it will quickly solidify and will not be suitable for further use. It is better to prepare the composition in small portions, which will be consumed within half an hour.
If the solution is too liquid or thick, its consistency can be adjusted by adding water and a powder "Volma. Layer". After the mixture is well mixed, it is allowed to stand for 2-3 minutes and proceed to work.
For the application of the composition by hand, standard spatulas (of different sizes), trowels, the rule of the required length and leveling trowels are used.
Plaster "Volma. Layer "is applied in four stages.
The first is alignment. On the walls, a large layer of plaster is applied and it is leveled by lighthouses with the help of a long rule. If the wall is relatively flat, you can do without lighthouses. The rule is taken from the floor to the ceiling, removing all excess solution and filling the grooves.
An hour after the application of the plaster (when its surface is dried), they begin to trim. At this stage, the rule cuts all the dried excess mixture to align the surface.
If in the future the walls will be pasted with wallpaper or decorated with tiles, on this their alignment can be completed. Before proceeding to the subsequent finish, the surfaces are treated with a primer.
If no other material is placed on top of the plaster, the walls must be brought to an ideal state. For this, they are smoothed and glossy.
Using a float with a spongy plane, the plaster is begun to be smoothed. These works should be started 15-20 minutes after the completion of the previous stage. The surface is wetted with water and passed through it with a grater (until the so-called milk is formed). At this point, the friction will increase significantly, and in order to hold a tool through the wall, you will have to make efforts. This process is necessary in order for the released liquid to fill all the microscopic cavities and smooth the surface.
The final stage is gloss. Using a metal float, the walls are rubbed and compacted with remaining irregularities. After processing, they are left to dry completely for the time indicated by the manufacturer on the package.
Gypsum plaster "Volma. Layer ", the characteristics of which we tried to consider in detail in our article, is distinguished by an acceptable cost. Moreover, it will not be difficult to find it on the market, since this compound is very popular today.
So, depending on the region of sale, 1 kg of gypsum mixture of this variety costs about 10-15 rubles. The average price of a bag weighing 30 kg today is 290 rubles. Thus, focusing on the consumption of material, you can calculate not only the right amount of mixture, but also the cost of repairs.
That's all. We hope that we answered all your questions. We wish you good luck and easy repair!
