Finishing materials manufacturers striveto provide their products with optimal qualities for the formation of durable and attractive coatings externally. It is not always possible to lay the lining on surfaces that have not undergone preparatory treatment. In particular, the alignment of walls and ceilings will help to perform polymer putty, which is easy to apply and provides a good result. There are different types of such compositions that have individual qualities and characteristics.
General information about polymer putty
Before the start of the finishing work the master conductsfinal revision of the surface on which the decorative coating will be applied. Requirements for the draft basis may be different - depending on the material being laid. As practice shows, the putty polymer finish is capable of forming coatings that are suitable for the most whimsical and delicate finishing. This applies to wallpaper, textile coatings, plaster and thin panels. The putty hides minor defects on the surface of the rough base, which are no longer manifested during the operation of the decorative design.
Some compounds also reinforce the construction.soundproofing effect and insulating function. But in most cases, the polymer putty is still used to level the surfaces in order to neatly perform the future lining. It is important to bear in mind that such mixtures are not intended to seal deep damage. In correcting such defects, it is recommended to apply priming compositions initially, and then draw them in with a finishing putty.
Main characteristics
When choosing it is important to take into account such characteristicsas a thickness consumption, the period of preservation of plasticity, as well as the time after which the main finish can be laid after grinding with polishing. In particular, the consumption of mixtures at the rate of 1 kg is usually recommended for a layer 1 mm thick. By the way, polymer putty is characterized precisely by the ability to form ultra-thin coatings that are optimally suitable for painting. After applying the user has another 24 hours to adjust the composition, without violating its structure. And after 2 hours, you can apply a decorative layer of the main finishing material.
Special qualities
Traditional formulations were mainly calculated ona narrow set of properties, which were sufficient for a relatively smooth laying of cladding. Today, the putty is already a multifunctional preparatory coating, which provides a reliable basis. Among the special qualities can be noted vapor permeability and moisture resistance. Due to these properties, polymer putty for interior work can be used in the preparation of kitchen and bathroom walls. Other compositions are suitable for such works, but not every mixture can provide durability and protection from negative biological processes under a layer of finishing material. And, on the other hand, the material is resistant to elevated temperatures, so it can be laid in thin layers in heated rooms.
Varieties
Polymeric compositions are available in two versions -on latex and acrylic bases. In the first case, the mixture is intended only for repair operations indoors. Such coatings are distinguished by plasticity, strength, lack of smell and durability. In practice, the use of preserved coating structure and the absence of negative deforming processes. If a universal, from the point of view of laying, composition is required, then the acrylic putty will be optimally suitable - the finishing white polymer mass will allow ennoble both the walls of the room and the facade of the building. Such coatings are moisture resistant, which protects the basis for finishing from the effects of precipitation. But acrylic has one serious feature nuance. The fact is that such mixtures are characterized by a high rate of hardening. With large amounts of work, this can cause a lot of problems.
Styling tips
The surface must be ready to be coated.putty, that is, to be cleaned and, if possible, free from deep defects. In extreme cases, a primer layer can be applied to the surface, but only from those compositions that provide sufficient adhesion to the leveling mass. Polymer putty is applied with a metal spatula. The optimum layer thickness is 0.5-1 mm, but in extreme cases it is possible to increase this value to 2 mm. Also, when working with problematic surfaces, it is recommended to apply several layers. After each stratum, it is important to leave time for its polymerization - about 4-5 hours. If it is required to combine alignment with the primer function, then it is possible to alternate the application of putty and primer mass. This will provide additional adhesion between the layers. After installation, grouting should be performed. For this operation it is necessary to use a fine-grained abrasive. At this stage a smooth and even surface should be formed by light grinding.
Positive feedback on polymer putty
As a material for partial groutingindoors, such compounds show themselves from the best side. Users note the plasticity, ease of application, the tenacity of the mass, and undemanding of the conditions of use. Separately emphasized and aesthetic advantages. For example, a white polymer putty resembles a gypsum panel in appearance - both the texture and the texture of the coating hints at this. Also, euphonious reviews of this composition receives from those users who used demanding materials for the base. For example, some types of wallpaper should be applied on an immaculately flat surface, and only with a white shade. And polymer-based putty copes with similar functions better than other analogues.
Negative feedback
If a more detailed comparison withalternative options for putty, the disadvantages of the polymer mass will be expressed quite clearly. So, the owners of private houses say that using such a grout for exterior decoration is not appropriate. Of course, acrylic blends are also suitable for such tasks, but facade cladding is not their forte. In any case, gypsum and cement compositions perform similar tasks an order of magnitude better. Also, dry polymer putty is not recommended for processing surfaces that have large areas with damage. Since such mixtures are expensive, the consumption of primer does not justify itself. Again, it is more expedient to either switch to universal putty, or choose a full-fledged primer. In other words, polymeric compositions are more suitable for specialized tasks indoors.
Conclusion
Synthetic blends of this type are available on the market.in different packing form. The most popular is the container in the form of 25-pound baggy bags, which contain polymer putty. The price of this product is an average of 300-500 rubles. This is not an expensive construction product, but it is more likely to provide the quality of performance of target tasks. It is desirable to choose such means taking into account the characteristics of the finishing material. For example, even if internal work is planned, the use of polymer blends is not necessary in preparation for installing the same plasterboard panels or wall paneling. Such facing materials are well combined with cement and plaster compositions, providing a higher adhesion. But if you plan to design the room with expensive wallpaper or paintwork, then the polymer composition will cope better than anyone.
