Varieties of plaster "Volma": "Layer". Characteristics and technology of application
It is impossible to imagine the overhaul of the premises without leveling the internal walls. For these purposes, often used sheets of drywall, but recently this material appeared worthy alternative - plaster "Volma. Layer". This product has recently appeared on our market, but has already managed to win the sympathy of many consumers. What are its features, what qualities it has, where it can be used and how to apply, we will look at in our article.
Volma. Layer plaster is marketed as a white powder mixture, the main component of which is gypsum. In addition to it, the material includes various polymer additives that provide the coating with excellent adhesion to the base, impact resistance and resistance to moisture.
The product is intended for manual finishing of walls in rooms where a stable microclimate prevails. This type of plaster is suitable for use on walls and ceilings. On sale the structure meets in packings on 5, 15, 25 and 30 kg.
Volma. Layer material gained its popularity due to a number of positive qualities. Namely:
- Ease of application. Plasticizers that make up the mixture, make its application quite simple, so make special efforts in the process is not necessary.
- No shrinkage. Unlike similar means for leveling walls, Volma plaster can be applied in one large layer (up to 6 cm).
- Environmental friendliness. The manufacturing company for the manufacture of its products does not use harmful components, as indicated on the packaging of the material.
- No need to putty walls. Plaster "Volma. Layer" can be applied immediately to the walls, without pre-treatment. After the mortar 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 room.
Volma. Layer gypsum mix: material specifications
Choosing one or another finishing material, you should focus on its main indicators. At Volma plaster they are:
- from 8 to 9 kg of dry mix is required for processing one m² of surface (depending on the layer thickness);
- optimal thickness of the applied layer - 5-30 mm;
- maximum permissible layer thickness - 60 mm;
- complete drying of the surface occurs after 6-8 days after application;
- 1 kg of dry composition requires from 600 to 650 ml of liquid;
- plaster can be applied to surfaces whose temperature is in the range of +5 to +30 degrees;
- the initial setting of the solution occurs 45 minutes after application;
- Compressive strength is 3.5 MPa;
- bending surface strength - 1.5 MPa.
In addition to all of the above, you should know another nuance that is important to consider when starting to work with the composition "Volma. Layer". Technical characteristics of the material indicate that the ready-made solution is suitable for work 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 jobs. The scope of use of the material is limited only by the fact that its main component absorbs moisture very strongly, therefore it is not recommended to use the composition outdoors and in damp rooms.
Most often plaster plaster "Volma. Layer" is used for the following works:
- when restoring and removing small surface defects;
- in minor repairs for leveling walls and ceilings;
- at primary and capital alignment of surfaces;
- as a wall covering;
- to create various decorative elements of the interior (arches, stucco, sculptures, etc.).
How to prepare the surface for the application of the composition
Now let's look at how simple the Volma. Layer mixture is at work. The manufacturer’s instructions indicate that no pre-treatment of the walls is required before applying the plaster; nevertheless, a little attention should be paid to the treated surfaces.
To get a decent result you will need:
- Remove dirt, dust and other debris from the walls that will interfere with work.
- If the walls were painted or plastered, the old finish must be completely removed.
- If there are deep cracks, chips and other defects on the surface, they are removed and covered with a putty.
- If the walls are strongly curved and it is planned to apply a thick layer of plaster, you should install beacons from the profile.
- All metal objects located on the surface of the base are treated with anti-corrosion compounds.
How to properly dilute the dry mixture
For the preparation of the working composition should be used only plastic buckets or other containers. First of all, clean water is poured into the bucket (at the rate of 600 ml per kg), and only then the dry composition of “Volma. Layer” is poured. Gypsum mixture is kneaded until homogeneous with a drill or a special mixer.
Please note that kneading a large amount of the mixture immediately is not worth it, as it will quickly harden and will be unsuitable 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 thin or thick, its consistency can be adjusted by adding water and powder "Volma. Layer". After the mixture is well mixed, it is allowed to stand for 2-3 minutes and proceed to work.
To apply the composition manually, standard spatulas (of different sizes), trowels, a rule of the desired length and leveling trowels are used.
Plaster "Volma. Layer" is applied in four stages.
The first is alignment. A large layer of plaster is applied to the walls and leveled at the beacons with the help of a long rule. If the wall is relatively flat, you can do without the lighthouses. The rule is led from the floor to the ceiling, removing all excess mortar and filling the recesses.
An hour after applying the plaster (when its surface is dry) proceed to trimming. At this stage, the rule cuts off all dried excess mixture to level the surface.
If in the future the walls will be covered with wallpaper or decorated with tiles, on this their alignment can be finished. Before proceeding to the subsequent finishing, the surface is treated with a primer.
If there is no other material over the plaster, the walls should be brought to a perfect condition. To do this, they smooth down and give them a glossy look.
With the help of a grater with a spongy plane, the plaster begins to smooth down.These works should be started in 15-20 minutes after the completion of the previous stage. The surface is moistened with water and float through it (until the formation of the so-called milk). At this point, the friction will increase significantly, and in order to carry the tool on the wall, you will have to make an effort. This process is necessary so that the released liquid fills all the microscopic cavities and smoothes the surface.
The final stage is glossing. With the help of a metal grater, the walls are rubbed and tamped down the remaining irregularities. After processing, they are left to dry completely for the time specified by the manufacturer on the packaging.
Gypsum plaster "Volma. Layer", the characteristics of which we have tried to consider in detail in our article, has an acceptable cost. Moreover, it will not be difficult to find it on the market, as this compound is very popular today.
So, depending on the region of sale, 1 kg of a 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 the mixture, but also the cost of repair.
That's all.We hope we answered all your questions. We wish you good luck and easy repair!
