Putty is a special mixture that is used for roughing, preliminary leveling and preparing surfaces for painting, gluing and other types of decoration. Such a composition may contain special foaming elements, fillers (chalk, talc, barite), as well as coloring pigments.
The substance has a pasty consistency, therefore it is recommended to impose it on the walls with a special tool - a spatula. After some time after application, the mass hardens, and all excess is removed with emery sheets or a rough sponge dipped in water.
Dry putty, which must be mixed with water in recommended proportions before use. To make a thick homogeneous mass, you must adhere to the requirements of the manufacturer's instructions, as well as use a construction mixer or other mixing equipment.
Such a powder is stored in special bags (bags) to prevent interaction with moisture. Its main advantage is an affordable price, but some efforts will have to be made to achieve the desired results. This option can be used for almost any kind of work, including where high accuracy and accuracy are needed.
The main disadvantage is the fragility of the already prepared mixture, so you have to calculate how much work will be performed immediately.
Ready putty, unlike the previous version, can be stored for a long time, but care should be taken to keep the container airtight.
In addition, the finished mass is more practical, because you do not need to deal with its preparation and bringing to a certain state. All components are already mixed in the right proportions and ready for application to the surface.
The disadvantages include a higher cost, as well as the inability to use on thin layers due to the tendency to shrink.
Modern putties can be divided into several types, depending on the type of cementitious base:
- gypsum - do not shrink after drying; they lend themselves well to the leveling procedure. They are mainly used for interior decoration, since they do not have moisture resistant properties.
- cement - are used for both external and internal works. Differ in the increased moisture resistance, frost resistance. This type of putty binds well brick, stone, concrete and other surfaces.
- polymer - characterized by high strength and increased resistance to various influences (temperature changes, moisture, ultraviolet). It does not crumble over time, as it is deeply absorbed into the porous structure of the wall.
By purpose, putty is leveling, finishing, universal and specialized. Note that this classification criterion is the most important and essential.
The leveling facing mixture is used for preliminary deep impact on the material. Here, the choice depends, first of all, on the basis on which the substance will be superimposed. It is recommended to pay attention to the indicator of adhesion (absorption), strength and durability.
Finishing - necessary to create a second layer, used before decorative decoration. The minimum grain size allows you to fill in all remaining defects and pores.
To solve a specific problem, specialized putty is used, for example, for sealing joints or expansion joints.
Universal analogues combine the advantages of all of the above options. They are very practical and suitable for any reason. However, it is worth noting that to solve a specific problem, it is better to use a specialized framework.
When choosing finishing materials, always read the manufacturers recommendations given in the instructions, which indicate the purpose of the product and its characteristics.
