Modern construction materials - warm plaster. Part 1

Now economic hypermarket can be confused by the abundance of materials proposed to be used for the facades. Familiar lime, chalk, clay becomes unclaimed.

They were replaced by substances that have several beneficial properties simultaneously, such as energy efficiency and aesthetics, durability and ease of use of technology. We are talking about the warm plaster.

Product Specifications

The high cost of energy makes to seek opportunities to minimize heat loss through the building structures themselves, materials and methods of their application. Thus it was invented aerated concrete, which is a solid foundation walls and at the same time retaining good heat.

In accordance with the thermo-technical regulations for protecting a building against the cold insulation layer thickness should be equal to 10-15 cm. Then, it is necessary to hide under the other outer layer furnish. This requires large material costs, human resources, and other factors.

These problems helps to avoid warm plaster. It is beneficial by the fact that is the simplest way of overlaying. Even an inexperienced plasterer cope with the task without loss of quality and get a certain level of professionalism.

All statements regarding the plaster indicate it as a material having the following characteristics:

Low thermal conductivity;
high environmental friendliness;
optimal hygroscopic;
minimum degree of refinement.

warm plaster a thermal conductivity comparable to polymeric foam and heaters in the absence actively interacting with aggressive components air. For the price it is competitive with expensive PUR and PIR panels. Therefore, the material can be safely applied in painting and decorating indoors.

The product within 100 days was subjected to direct contact with water under atmospheric pressure. The substance has absorbed less than 3% moisture.

At the same time the degree of hygroscopic raw materials allows us to speak about normal air exchange. Applying it indoors does not transform the room into a thermos. A use of a product with all known heaters avoids condensation which could cause freezing winter insulated surface. Warm plaster even with large layer overlaying does not require additional alignment and decorating. the surface grinding can be carried out to the lowest level of roughness.

The qualitative composition of the compound

The structure of the original plaster similar to normal, but it has its own peculiarity. Instead of quartz sand filler plays a role porous material with closed cells. Traditionally, the use of expanded perlite or vermiculite. More expensive sample mixtures include granular foamed glass. Rarely have resorted to adding the reinforcing material with the polymer fiber.

Polymer Chemistry also contributed to the creation of a unique mixture comprising a series of modifiers with a high degree of solubility in water. These include:

hydrophobic stabilizers, protecting the surface from getting wet;
catalysts interaction with air;
ductility enhancers.

The main binding component protrudes standard Portland cement, but the number of members is equal to 80% of the total weight of the substance. It turns out that if the proportion in ordinary plaster cement and fillers - 1: 4, then warm plaster contains a vast amount of cement. The stated properties of strength, hardness and adhesion of cement used should not be below M400 or M500. To improve the aesthetic background surface is not paid ordinary cement and white.

For applying warm indoor plaster material of the added gypsum, lime. These components increase the degree of vapor permeability. The resulting moist air is safely passes through the dried layer of solution not being deposited on the walls of rooms. Perlite or vermiculite help retain fluid in the process of slow drying and at the same time provide a high density material.

The surface can be painted after plastering and repainting. It is not allowed to use only the colors, forming a film after drying. These include alkyd and silicone materials. In the formation of 3-4 layers of paint surface must be sanded that restores the gas exchange processes. In the second part of this article we will focus on the use and technology to work with the material, especially the cooking at home. The second part of
