To date, the market of various building materials is filled with various goods extremely rapidly. New products appear almost daily. Иногда ее многообразие не позволяет достаточно быстро сделать однозначно безошибочный выбор. So let’s say, if you need a putty, today you can buy it at any building materials store, including going to the online building materials store. The choice there will be very extensive. Therefore, before you go there, it would be nice to get some knowledge about what you are going to buy.
Depending on what goals for the use of putty, they are divided into:
Universal. They are able to solve a large range of tasks. With their help, you can easily align the surface in any, even in very difficult external conditions, make a finish finish. As it may seem, it is very convenient. However, often a universal putty is actually not.
Specialized. Such putty are used with a specific purpose. For example, if you need to close the joints between drywall sheets, which were mounted on a profile under gypsum -melting, without applying a reinforcing tape.
Starting. They are the most common putty. Used for initial work with the surface. To make the right choice of starting putty, you need to take into account the type of base, as well as its properties and conditions of use.
The first layer is usually always more thick than subsequent. Consequently, the material for primary alignment should be very well fastened with the base, maintain strength for a long time, fill out absolutely all existing surface defects. This type of putty, as a rule, is not characteristic, neither shrinkage, nor less exfoliation.
The most important thing when applying it is to monitor compliance with the known rule: the base must always be much stronger than the material that is applied to it. It should be noted that starting putty most often do not require the use of reinforcing materials. I would like to note that when you choose a putty, you can opt for a material that retains your working properties for a long time. Despite the established opinion that supposedly a diluted putty is definitely a very short century, there are currently on sale compositions with a long “life of life”.
Finish. These putty are designed for the final preparation of the necessary surface and its decorative decoration. When choosing them, first of all, pay attention to the number of incoming particles in this material. The smaller they are, the more smooth in the end you get the surface. For example, if necessary, high -quality walls of walls or ceiling, you will need to purchase a putty with a grain of not more than 100 microns. There are such samples that allow you to create an even, perfectly smooth surface that will not need grinding.
