Walls made of clay are not the last century, but a reality that is found in houses built on the principle of environmental friendliness. The desire to make the home safe for all family members encourages the revival of the old methods of wall construction and decoration.
Modern technologies are improving the characteristics of housing and its operation. Plastering clay walls has a lot of advantages, thanks to which it is very comfortable to be in such a house.
Modern eco-houses are durable and durable.
They perfectly retain warmth in winter, and in the summer heat, coolness is felt. When making a choice in favor of clay walls, the owners should be prepared to take into account a lot of nuances, because not everything is as simple as it might seem at first glance.
For clay walls, a composition with a low weight is suitable. For plaster of external walls, lime-based solutions are used, and clay or gypsum mixtures are suitable for interior decoration. It is not recommended to use cement plasters, since the material puts a lot of stress on the clay surface, and the finishing layer will deteriorate over time.
The technological process involves the creation of three layers:
In order to carry out the initial decoration of the walls, it is necessary to prepare the following materials:
The shade of clay mortar for plastering walls is also important. The most popular and affordable color is red. In addition, there are white, yellow, black and gray shades. The component composition of the clay contains minerals in the form of magnetite or quartz. It should be noted that these elements have a high level of radiation.
To prepare a solution of the rough composition of the plaster, the sawdust is combined with sand and water and clay are gradually added.
Taking into account the different characteristics of the clay, the proportions are selected optionally, by trial and error. The ratio of the components of the mixture looks like this - 1: 1: 3. You can check the readiness of the composition for plastering walls in two ways:
Important! The fine finishing of the clay walls provides for the absence of sawdust in the plaster. This is due to the fact that they absorb moisture and increase in size, thus breaking the integrity of the coating.
Sawdust is a guarantee of strength and reliability of plaster for wall decoration. Their absence is compensated by attaching a reinforcing mesh made of nylon on the surface of the clay walls. The reinforcement is fixed with mortar, excluding the use of nails, which violate the integrity of the walls, thereby impairing the reliability of the structure.
It is easier to work with an assistant who will coordinate the work of the master and show the areas that need improvement.
The process involves several stages:
When working on large rooms with clay walls, simplify your work by installing beacons for plastering the walls. This will speed up the application process and increase quality.
After finishing work on finishing the walls with a rough layer, the walls are left to dry for 4-6 weeks. One centimeter layer of plaster dries in 5 days. Experts advise against using hair dryers or heaters to speed up the process. So that the natural drying process does not drag on for a long time, it is better to carry out work in the summer. Initial finishing starts in May-June, depending on the climatic zones of the country.
Finishing the walls is the final alignment of the clay walls with plaster, bringing to the ideal. After leveling the surface, proceed to grouting. To do this, you need to make a mortar from cement, sand and clay.
Sawdust is not added to the composition, since they violate the smoothness of the walls. When mixing, the proportions of 3: 1: 1 are observed, taking into account the quality of the clay.
It often happens that much more sand is required. The consistency of the solution should turn out to be liquid, since in this form, it is easier to apply it to clay walls. Before mixing, the sand is sieved in order to separate large particles.
Stages of preparing mortar for finishing:
Fine interior wall plaster dries completely within 1 to 3 weeks, depending on the room temperature.
Natural drying is essential, otherwise the plaster will crack.
After the finishing layer dries up, proceed to the finishing of the clay walls. The process takes place in several stages. The surface of the clay walls is rubbed with fine emery paper. Then the primer is applied in two layers, allowing each of them to dry completely.
Next comes the turn of plastering the clay walls with gypsum plaster, which is decorated at your own discretion. You can use wallpaper or paint.
Clay wall decoration requires a special approach, taking into account the mass of nuances. Sometimes the finishing is carried out with lime-based plaster, without the inclusion of cement. In addition to the gypsum composition, asbestos is used.
The quality of the clay affects the composition of the proportion of the mortar at all stages of the repair. It is important to carefully monitor the presence of radioactive minerals.
If you follow the guidelines for creating environmentally friendly housing, use quality materials that contribute to the formation of a beneficial indoor climate, you can save money while getting a dream home.
