Finishing technologies are developing steadily. Therefore, one should be wary of making a mistake when mixing the mixture. There are certain rules that allow you to properly connect all the components included in the cement mortar. The proportions that must be strictly enforced will help to plaster the most different types of walls in the best possible 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 a binder component in these types of mixtures there is cement, 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, contains sand as a filler. This component gives the mixture strength.
Types of cement mortars for plaster
Depending on the type of the binder component, the proportions of the cement slurry for plaster are chosen. On the basis of this material, there are cement, cement-lime and clay-cement varieties of mixtures.
Cement mortar in a certain proportion is used for wet rooms, for processing the lower part of the foundation, exterior walls and plinths. If waterproof additives are added to such a mixture, the plaster will play the role of isolation. Cement mortar, the proportions for the plaster of which are quite simple, allows you to apply it on fairly large areas.
Cement-lime mortar is used for the exterior walls of wet rooms. It is laid in a thin layer. It is more plastic than cement mix.
Clay-cement mortar is quite suitable for plastering walls indoors with a normal level of humidity. External work from such material is produced only in a dry climate.
Proportions for cement mortar
Cement mortar known builders for a long time. This is a rather stiff mixture that is not easy to apply evenly 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.
Cement consumption with increasing plasticity of the material increases. 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 brand of such a cement-lime mortar is determined by the brand of cement. To prepare such ratios of components is possible 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 lime dough with water.
You can also use this component in the water-undiluted state. It is mixed with sand, and then water is added. In the resulting mixture, the cement is added last and everything is 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.
Cement mortar, enriched in a similar way, has several advantages. Its consumption is much less, and the use of plaster mesh is generally not required. Increased elasticity will make the coating resistant to changes in temperature and humidity. Plastered surfaces will let in air, which will prevent the formation of fungi and microorganisms on the surface.
For the average consumer, the use of such mixtures is very convenient. After all, you only need to add water to the cement mortar. The proportions of the components have already been calculated by the technologists of the company that produced such a product.
For those who prepare the solution themselves, you should follow the technology of creating a mixture. For this, the raw materials are initially sieved through a sieve. This will help 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 comfortable to work with, and all its components must be thoroughly mixed until a homogeneous mass.
After reviewing the main types of cement-based mixtures, you can choose the right type for their specific type of work. For each type of base, an appropriate plaster mix should be used. Accurate implementation of the technology will help to prepare the correct cement mortar. The proportions of its components, sustained in accordance with the norms and requirements of construction work, will guarantee the durability and functionality of the material.
