Polymer filler: overview, types, specifications and reviews

Manufacturers of finishing materials strive to give their products the optimum qualities for the formation of durable and attractive exterior coatings. In this case, it is not always possible to lay the liner on surfaces that have not undergone a preparatory treatment. In particular, the leveling of walls and ceilings will help to perform polymer filler, 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 on Polymer Putty

Before the beginning of finishing works the master conducts the final revision of the surface, on which the decorative coating will be applied. Requirements for roughing can be different - depending on the material being stacked. As practice shows, putty polymer finishing is capable of forming coatings that are suitable for the most capricious and delicate finish. This applies to wallpaper, textile coatings, plaster and thin panels. Putty hides small defects on the surface of the roughing base, which no longer appear in the process of using the decorative design.

Some compounds also reinforce the construction with a soundproofing effect and a warming function. But in most cases, the puttying polymer is still used for leveling the surfaces in order to accurately perform the future cladding. It is important to take into account that such mixtures are not intended for sealing deep damages. In the correction of such defects it is recommended to initially apply priming compositions, and then make out their finishing putty.

Main characteristics

When choosing it is important to take into account such characteristics as thickness consumption, the period of plasticity preservation, and also the time through which the main finish can be laid after grouting. In particular, the consumption of mixtures is generally recommended at a rate of 1 kg with a layer 1 mm thick. By the way, polymeric putty differs precisely in its ability to form ultra-thin coatings that are optimally suitable 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 Features

Traditional compositions were mainly calculated for a narrow set of properties, which were sufficient for a relatively even laying of the cladding. To date, 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, polymeric putty for interior work can be used in the preparation of kitchen walls and bathroom. 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 high 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 inside the premises. Such coatings differ in plasticity, strength properties, absence of odor and durability. In practice, the use of preservation of the structure of the coating and the absence of negative deforming processes are noted. If you require a universal, in terms of stacking, the composition is optimal acrylic putty - the final white polymer mass will allow to improve both the walls of the room and the facade of the building. It is these coatings that are characterized by moisture resistance, which protects the basis for finishing from the effects of precipitation. But acrylic has one serious nuance in the characteristics. The fact is that such mixtures are characterized by high pouring rate. With large amounts of work, this can bring a lot of problems.

Installation Tips

The surface should be ready to be coated with putty, that is, to be cleaned and, if possible, free from profound defects. In extreme cases, it is possible to apply a primer coat to the surface, but only of those compositions that will provide sufficient adhesion to the smoothing mass. Apply polymer filler with a metal spatula. The optimum thickness of the layer is 0.5-1 mm, but in extreme cases it can be increased to 2 mm. Also, when working with problem surfaces it is recommended to apply several layers. After each layer it is important to leave time for its polymerization - about 4-5 hours. If alignment with the priming function is required, it is possible to alternate the application of putty and primer. This will provide additional adhesion between the layers. After the installation, grout should be carried out. For this operation, it is necessary to use a fine-grained abrasive. At this stage, by smooth grinding, a smooth and even surface should be formed.

Positive feedback on polymer fillers

As a material for partial grouting of walls inside the premises, such compositions show themselves on the best side. Users note the plasticity, ease of application, tenacity of mass, and also undemanding application conditions. Aesthetic advantages are also highlighted. For example, putty white polymeric looks like a plaster panel - this is hinted at both texture and texture of the coating. Also euphonious reviews this composition receives from those users who used for finishing materials that are demanding for the basis. For example, some types of wallpaper should be applied to a perfectly smooth surface, and only with a snowy shade. And putty on a polymer basis copes with similar functions better than other analogues.

Negative feedback

If more detailed comparison with alternative shpaklevki options, the shortcomings of the polymer mass will be expressed quite clearly. So, owners of private houses note that it is not advisable to use this grout for exterior finishing. Of course, acrylic blends are suitable for such tasks, but the facade cladding is not their strong point. In any case, gypsum and cement compositions perform similar tasks in order of magnitude better. Also, dry polymeric putty is not recommended for treating surfaces that have large areas with damages. Since such mixtures are not expensive, the consumption of priming operations does not justify itself. Again, it is more expedient to switch to universal filler, or to choose a full primer. In other words, polymer compounds are more suitable for specialized indoor tasks.

Conclusion

In the market, synthetic blends of this type are available in different packing forms. The most popular is the container in the form of 25-kg baggy bags, which contain polymer filler. The price of such a product is on average 300-500 rubles. This is not a cheap construction product, but it is more likely to ensure the quality of the targets. It is desirable to choose such means and 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 the installation of the same gypsum board or lining. Such facing materials are not bad combined with cement and gypsum compositions, providing even higher adhesion. But if you plan to decorate the room with expensive wallpaper or paint and varnish, the polymer composition will cope better than all.
