Producers of finishing materials strive to endow their products with optimal qualities for the formation of durable and attractive coatings. At the same time, it is not always possible to lay the cladding on surfaces that have not undergone preparatory processing. 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 compounds that have individual qualities and characteristics.
General information about polymer putty
Before starting finishing work, the master conducts a final revision of the surface on which the decorative coating will be applied. The requirements for the rough base may be different - depending on the material being laid. As practice shows, polymer finishing putty is able to form coatings that are suitable for the most whimsical and delicate finishes. This applies to wallpaper, textile coverings, plaster and thin panels. Putty hides minor defects on the surface of the rough base, which no longer appear during the operation of the decorative design.
Some compounds also reinforce structuressoundproofing effect and warming function. But in most cases, polymer putty is still used to level surfaces in order to accurately perform future cladding. It is important to consider that such mixtures are not intended for sealing deep damage. In correcting such defects, it is recommended to initially apply priming compounds, and then decorate them with finishing putty.
Key Features
When choosing, it is important to take into account such characteristics as consumption by thickness, the period of plasticity retention, as well as the time after which the main finish can be laid after grouting by grinding. In particular, it is usually recommended to use mixtures at the rate of 1 kg for a layer 1 mm thick. By the way, polymer putty is distinguished precisely by the ability to form ultra-thin coatings that are optimally suited for painting. After application, 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 compositions were mainly calculated on a narrow set of properties that were sufficient for a relatively even laying of the cladding. To date, putty is already a multifunctional preparatory coating that provides a reliable base. Among the special qualities, vapor permeability and moisture resistance can be noted. Thanks to these properties, polymer putty for interior work can be used in the preparationkitchen and bathroom walls. Other compounds are also suitable for such work, 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
Polymer 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 properties, odorlessness and durability. In practice, the preservation of the coating structure and the absence of negative deforming processes are noted. If you need a universal, in terms of laying, composition, then acrylic putty is best suited - the finishing white polymer mass will ennoble both the walls of the room and the facade of the building. It is these coatings that are moisture resistant, which protects the base for finishing from the effects of precipitation. But acrylic has one serious nuance in its characteristics. The fact is that such mixtures are characterized by a high solidification rate. With large volumes of work, this can cause a lot of problems.
Styling Tips
The surface must be ready for coating with putty, that is, be cleaned and, if possible, free from deep defects. In extreme cases, you can apply a layer to the surfaceprimers, but only from those compositions that will provide sufficient adhesion with the leveling mass. Polymer putty is applied with a metal spatula. The optimal layer thickness is 0.5-1 mm, but in extreme cases this value can be increased to 2 mm. Also, when working with problematic surfaces, it is recommended to apply several layers. After each layer, it is important to leave time for its polymerization – about 4-5 hours. This will provide additional adhesion between layers. After installation, grouting should be done. For this operation it is necessary to use a fine-grained abrasive. At this point, light sanding should give a smooth and even surface.
Positive feedback on polymer putties
As a material for partial grouting of indoor walls, such compositions show their best side. Users note plasticity, ease of application, tenacity of the mass, as well as undemanding to the conditions of use. Aesthetic advantages are also emphasized separately. For example, white polymer putty looks like a gypsum panel - both the texture and the texture of the coating hint at this. Also, this composition receives euphonious reviews from those users who used materials that are demanding on the base for finishing. For example, some types of wallpaper must be applied to a perfectly flat surface, and only withsnow-white shade. And polymer-based putty copes with similar functions better than other analogues.
Negative reviews
If we compare in more detail with alternative putty options, then the disadvantages of the polymer mass will be expressed quite clearly. So, the owners of private houses note that it is not advisable to use such a grout for exterior decoration. Of course, acrylic mixtures are also suitable for such tasks, but facade cladding is not their forte. In any case, gypsum and cement compositions perform similar tasks much better. Also, dry polymer putty is not recommended for processing surfaces that have large areas with damage. Since such mixtures are not cheap, the cost of priming does not justify itself. Again, it is more expedient to either switch to a universal putty, or choose a full-fledged primer. In other words, polymer compounds are more suitable for specialized indoor applications.
Conclusion
Synthetic blends of this type are available on the market in various packaging forms. The most popular is the container in the form of 25-kilogram baggy bags, which contain polymer putty. The price of such a product is on average 300-500 rubles. This is an expensive building product, but it is more likely to provide the quality of the target tasks. It is desirable to choose such means and taking into account the characteristicsfinishing material. For example, even if internal work is planned, the use of polymer mixtures is not necessary in preparation for the installation of the same plasterboard panels or lining. Such facing materials are well combined with cement and gypsum compositions, providing higher adhesion. But if you plan to decorate the room with expensive wallpaper or paintwork, then the polymer composition will do the best.
