Modern variety of components of warm plaster
All without exception thermal insulating plasters include in their composition two components: a binder and a porous filler. The role of the former is often given to high-strength cement, but a wide variety of materials can be claimed for filler: slag, sawdust, vermiculite balls. Today, the tendency of the use of organic fillers is reviving, for example, for interior improvement works. Therefore, the composition of warm plaster, depending on the place of its use, plays an important role.
Foamed silicon can also play an effective role as a filler. After going through a complex technological process, silicon turns into strong and light balls. The uniqueness of such a filler is that the pores have a size sufficient to penetrate the air, but not enough to penetrate the moisture.
Characteristics of warm plasters - thermal conductivity and moisture resistance
Before you go into the details of the characteristics of warm plaster, it is worth noting that fillers, albeit synthetic, do not emit harmful substances during operation. The same happens when a fire occurs.
Returning to the characteristics, the first thing to do is to touch the thermal conductivity of the plaster. Considering that cement is included in the composition of warm plaster, which forms cold bridges in order to achieve the best preservation of heat, it is necessary to lay the layer twice as thick, if analogy with mineral wool or styrofoam.
As for the absorption of moisture, modern fillers in the form of modified granules allow to exclude the penetration of moisture inside the warm plaster. What can not be said about the cases when the expanded filler is used expanded vermakulit. At the same time, it's easy to take moisture, it just gives it away. This effect is not the first year successfully used by farmers.
How to make and effectively apply warm plaster yourself?
The warmest plaster with its own hands is suitable for cases when the walls of the structure are made of cinder blocks, cellular concrete or hollow blocks. Their thermal conductivity index is slightly higher than the , rather than the traditional brick, and additional warming will not hurt. Therefore, the use of warm plaster allows you to kill two birds with one stone:
- on the facade of the building will not only be rendered plaster, but also the thermal insulation coating
- , in addition, decorative decoration can be performed at the same time.
It is not difficult to prepare a mortar for laying a warm plaster with your own hand. Here you need a certain set of natural materials: clay solution( 1 part), paper weight( 2 parts), cement( 0.2 parts), sawdust( 3 parts).It is also not difficult to apply this kind of plaster. The main application of this solution is in the process of working inside the premises of the .If the treatment is subject to a wooden wall, then it is better to fill the mesh on its surface, or to fill nails every 20 centimeters. Nails need to be finished not completely, leaving a certain part( about 20 mm).If the wall needs to be made perfectly even, you need to install beacons. If you need to work with block or brick walls, then the surface should only be cleaned of paint and abundantly moistened with water.
