Warm plaster for interior works - veryunusual and new for many construction and finishing materials, which appeared relatively recently in the domestic market. Accordingly, it is quite natural to consider the question of what kind of building mixtures - warm plasters - and how to use them.
Warm plaster for interior works - drya mixture based on ordinary cement. The difference from the classic solution is the absence of sand in the composition. It can be replaced by any other components:
There are several types of warm plaster. The construction mixtures differ in composition, application, application method and technical and operational characteristics.
Among the most popular are the following three types of plaster.
Expanded vermiculite - light mineralaggregate, obtained by heat treatment of vermiculite rock. A warm plaster with the addition of such a component is used mainly for outdoor work. Despite this, it can also be used for interior finishing - it is a universal building material. Among the advantages of vermiculite warm plaster, you can include excellent antiseptic properties.
Warm plaster for interior works,which is very popular and not intended for outdoor decoration - the so-called sawdust mixture. It consists of sawdust, particles of cement, clay and often paper. Actually, it is for this reason that it is not used in outdoor works.
Such a mixture is ideal for application towooden and brick surfaces. The applied plaster layers should dry only if the room is well ventilated. Full drying takes about two weeks. In a closed room on the surface of the plaster can develop fungus and mold.
Another good type of plaster is the mixture withaddition of expanded polystyrene granules. Its composition, in addition, includes cement, lime, various additives and fillers. It is used mainly for exterior finishing work, but it can be used for internal.
Plaster with expanded polystyrene granules is the most common, in contrast to the other two species.
To date, dry mixtures of this type are used in the following areas:
Proceeding from all the pluses and minuses of this dry mix, it is best to use it in the following works:
The base before applying a dry mixture of suchtype is prepared in the same way as before applying a conventional plaster on a cement base. Remains of other materials, dust and dirt are carefully removed. If necessary, the surface can be treated with special formulations or a primer in order to strengthen and improve adhesion.
An important requirement - before starting the plaster application, the substrate must be thoroughly moistened with water.
Sequencing:
Check the consistency of the resulting mixture verysimply - a small amount of solution is collected on the trowel, after which the tool is turned over. A qualitatively mixed mixture should not fall off it. Ready plaster can be applied both manually and mechanically.
During interior finishing works withThe use of warm plaster often can be made by those or other errors, especially if they are not engaged in specialists. As a result of this, delaminations, cracks or changes in the geometry of the entire room can occur due to the too thick applied layer.
The quality of the plaster works is checked quite simply: for this, a rake rule is applied to the surface. If there are gaps between the tool and the wall, there are violations of geometry.
When applying plaster, the most important thing is to prevent deviations from the vertical or horizontal lines by more than 3 mm.
Plaster is used (the price for it varies within 200-900 rubles per package), depending on the thickness of the layer: about 10-15 kilograms per square meter of the base.
If the work is done by specialists, then it will be necessary to pay about $ 15 for their services, not counting the cost of materials and tools.
Depending on the thickness of the walls, the material, fromwhich they are made, and the climatic zone in which the building is located, the size of the layer of the finishing composition also varies. According to standard calculations, a brick wall 51 cm thick can be insulated by applying a layer of plaster to it at 8-10 cm. Of course, such a mixture consumption is simply huge and irrational, so it is best used as an additional material. Unlike classic brick, aerated concrete or ceramic blocks require a much smaller layer of plaster.
Standard material thickness, recommendedmanufacturers, from 2 to 5 cm. To calculate the required amount of a mixture is simple enough, in addition, it is supplied in separate packages weighing 7-10 kilograms. The standard amount of plaster is enough, as a rule, to apply a layer of 2-2.5 cm per one square meter of surface.
Dry mix "Knauf" - very expensive finishingmaterial, which has good thermal insulation and water-repellent properties. Safe insulation, easily applied to the prepared substrate. Among its advantages include vapor permeability, resistance to weathering, absolute environmental friendliness and additional surface warming.
Plaster "Knauf" - the best option for interior finishing works.
Reviews about the plaster of this brand confirmwords of the manufacturer. According to consumers, the dry mix is easily kneaded, applied to the surface and has good adhesion. The plaster dries quickly enough, which is rather a plus than a minus. The finished coating has a pleasant beige-pink shade.
In the domestic market is in great demandplaster "Umka", which is intended for both exterior and interior decorating. It has good heat, sound and waterproofing properties.
Штукатурка абсолютно безопасна и экологически it is pure, differs in low hydrophobicity, heat conductivity and high level of porosity. Its composition includes mineral filler, which significantly increases the strength of the finished base. Silicon balls used as a filler significantly reduce the weight of the solution and increase its resistance to pressure.
"Teplover" - plaster, which includes vermiculite. Due to this component, the composition has a low density and thermal conductivity of the finished layer.
The mixture is highly resistant to moisture, which allows it to be used both for exterior work and for interior decoration of rooms with high humidity.
Such finishing materials can beused to eliminate third-party sounds. For example, to isolate "airborne noise" (TV noise, conversations, car engines), it is necessary to choose a composition with a fibrous structure and air flow through warm plaster. The thickness of the layer should be within 0.5 cm. To eliminate the “impact noise” - the sounds of footsteps, falling objects and knocks - it is necessary to acquire plaster with high elasticity.
Warm compounds, unfortunately, do not possess such properties, therefore, most likely, their thermal insulation qualities are somewhat overestimated.
Manufacturers produce not only classicplasters, but also special mixtures that are used to insulate roofs, floors, internal surfaces and floors. You can apply them on any basis, but despite this, on the packages it is often stated that it is best to work with smooth, even coatings - for example, aerated concrete or ceramic blocks. Before applying warm plaster to the surface, you can apply the usual vapor-permeable mixture.
Отделочный материал такого типа может used for both outdoor and indoor applications. However, the use of warm plaster is not always appropriate - it is often possible to purchase other, cheaper formulations that will give much better results.
Before starting the repair, it is advisable to take into account all the possible nuances and purchase exactly the material that is optimally suitable for solving the set goals.
