Finishing technologies are developing confidently. Therefore, you should be careful not to err when mixing the mixture. There are certain rules that allow you to properly connect all the components that make up the cement slurry. The proportions that must be strictly observed will help plaster the most different types of walls in the best way.
To prepare the right solution for plaster wagamama substance in certain proportions add special placeholders. Without them, the mixture will have sufficient strength and viscous. When dry, this plaster will crack and crumble. Therefore, the cement mortar for plastering walls, the Foundation is always combined with other substances in certain proportions. They are thoroughly mixed.
In the role of an astringent component in similar varieties of mixtures, cement is present, to which clay or lime can be added. The choice of additional components depends on the type of work performed.
Cement mortar, the proportions of which are determined depending on its composition, as a filler contains sand. It is this component that gives the mixture strength.
Types of cement mortars for plastering
Depending on the type of binder component, the proportions of the cement mortar for the plaster are also selected. Based on this material there are cement, cement-lime and clay-cement varieties of mixtures.
Cement mortar in a certain proportion used for wet rooms, for the treatment of the bottom of the foundation, external walls and socles. If waterproof additives are added to such a mixture, the plaster will play the role of insulation. Cement mortar, the proportions for plaster which are quite simple, allows you to apply it on a fairly large area.
Cement-lime mortar is used for exterior walls of wet rooms. It is laid in a thin layer. It is more plastic than a cement mix.
Clay-cement mortar is quite suitable for plastering walls in a room with a normal level of humidity. External works from such material are produced only in a dry climate.
Proportions for cement mortar
Cement mortar is known to builders for a long time. This is a fairly tough mixture, which is not so easy to apply exactly to the surface. The mixture can be stored for about an hour before starting work.
To prepare this cement slurry is used the following proportions. One part of the base has from 1 to 6 parts of sand. The more filler, the more rigid the product will succeed in the end. The ductility shall be cement mortar for plaster walls. The proportions of this mixture should be no more than 1:3. Then to the dry mixture water is added. It would take so that the solution has a good consistency, where it will be convenient to apply to the surface.
The consumption of cement increases with the plasticity of the material. But it can be easily applied to the wall, and then properly aligned.
Proportions for cement-lime mortar
Composition of cement-lime mortar allows it to be more plastic compared to cement mixes. This is a very good cement for the Foundation. The proportions of its components can be very diverse. Most builders use a ratio of parts of cement-lime-sand: 1х2х8, 1х2х9, 1х3х12, 1х3х15.
The mark of such a cement-lime mortar is determined by the cement brand. It is possible to prepare such component ratios in different ways. For example, you can first mix dry cement and sand, and then add lime milk to them. It is prepared by mixing the lime dough with water.
It is also possible to use this component in a water undiluted state. It is mixed with sand, and then water is added. In the resulting mixture, the cement is added last and thoroughly mixed.
In modern construction and repair work using cement mixture, prepared on the basis of enriched with polymers materials. They significantly increase the ductility, which must have cement mortar for plaster walls. The proportions of these additives are characterized by high accuracy, since they are counting in the laboratory. This ready to use mixture.
The cement mortar, enriched in this way, has a number of advantages. Its consumption is much less, and the use of plaster mesh is not required at all. Increased elasticity will make the coating resistant to changes in temperature and humidity. The plastered surfaces will let in air, which will prevent the formation of fungi and microorganisms on the surface.
For ordinary ordinary consumers the use of such mixtures is very convenient. It will only need to add water to the cement slurry. The proportions of the components have already been calculated by the technologists of the enterprise that produced such a product.
For those who prepare the solution on their own, one should adhere to the technology of creating a mixture. For this, the starting materials are initially screened through a sieve. This will help to achieve a uniform consistency.
Next you should give the solution the necessary fat. The mixture may be increased, normal, fat or skinny. Oily solution contains a large amount of binder component. It will quickly spread and settle. The normal level of fat should ensure the preparation of cement mortar. The proportions of the components in this case met the most harmonious way. Skinny solutions possess a high content of filler. They are tough and when dry will crack.
The consistency of the solution should be convenient for work, and all its components must be thoroughly mixed to a homogeneous mass.
Having become acquainted with the basic varieties of mixtures based on cement, one can correctly choose their variety for a certain type of work. For each type of substrate, an appropriate mixture must be used for plastering. Accurate implementation of the technology will help to prepare the correct mortar. The proportions of its components, held in accordance with the norms and requirements of construction work, will guarantee the durability and functionality of the material.
