Decorative plaster for outdoor works: description and technology of application

The appearance of any building, and even more so of an apartment building is of great importance. Therefore, the finishers and pay much attention to the procedure for the decoration of the facade. And if earlier it was difficult enough with this question, as sometimes it was necessary to almost literally almost invent the compositions of all kinds of solutions, today the market of building materials is ready at any moment to come to the rescue as a professional or a home master. To date, there is a huge number of all kinds of mixtures for the decoration of external walls of buildings, and the most popular is decorative plaster for outdoor works. This is not surprising, since this material has a lot of advantages and a small number of shortcomings.

About what has the pros and cons of decorative plaster for outdoor works, its types, basic characteristics and technique of application, we'll talk in our article.

Positive traits

Facade decorative plaster for outdoor works not only creates an attractive textured structure, it also protects the wall surfaces from moisture, that is, it is like a kind of shield for the outer surface of the walls. In addition, it is characterized by very, very high resistance to all kinds of temperature changes, and therefore the facade of the house finished with its help retains its original appearance long enough. Do not discount that it significantly increases the thermal insulation qualities of the walls, and also makes them less permeable to sound.

It allows to realize a lot of ideas for creating a building exterior, because, thanks to the special composition of each kind of this finishing material, it is possible to make various textured surfaces with its help. For example, decorative plaster "bark beetle" for outdoor works imitates the surface of wood, eaten by bugs, and the mixture of "fur coat" somewhat resembles the inner fur surface of sheepskin.

In addition to the basic composition, in this finishing material there are all kinds of additives - the so-called fractions, consisting of crushed minerals. Choosing a particular size of the faction, you can create a completely different structure of the coating. In addition, in addition to the basic shades (white and gray), you can buy already painted material. The choice of colors is quite varied, in the same case, if the suitable one was not found, it is possible to add the pigment pigment to the composition itself.

And one more huge plus, which has plaster decorative for outdoor works. It perfectly conceals small defects, special preparation before the beginning of works is not required, and the process of application is quite simple. In this regard, if you have a pair of skilful hands, you can apply all the finishing work yourself.

A spoon of tar…

True, it is not that big. The main disadvantage is that the entire prepared solution must be worked out within a certain period. That is, there are no breaks for smoke breaks. To sustain such a pace in the absence of appropriate skills of finishing works is quite difficult. The second minus is directly related to the next question, which we want to consider further. These are types of decorative plasters for outdoor works. There are both simple compounds, and complex, higher-quality ones. But they are much more expensive. In other words, if you want to make a better façade by acquiring a material with improved (however, already without it bad) characteristics, then finishing you will be very expensive.

In the following, we briefly review the currently existing species.

Cement plaster

It is made on the basis of cement and fractional inclusions. Such decorative plaster for outdoor works has all the characteristics described above, but it is not sufficiently resistant to loads, and as a result, cracks may appear on the walls during shrinkage. But these plasters have an affordable cost, in addition, the facades decorated with their use are easily amenable to restoration. Simply put: the emerging defects can easily be repaired, and outwardly it will not be noticeable. Another disadvantage is that the palette of the produced colors is rather poor, so it's not always possible to choose the shade of interest. Nevertheless, cement plaster is the most popular in finishing, which is not surprising, as the area of the facades is quite large, and therefore not every homeowner can afford to lay out significant sums for the purchase of better materials. The same, which can, it is recommended to pay attention to the following kind of finishing material.

Acrylic plasters

If the cement is produced in dry form, then this decorative plaster for outdoor works (see photo below) is realized already in ready form, packed in buckets. In its composition there is an acrylic filler, which gives the composition the necessary plasticity, so that the walls that are finished by it less suffer from the appearance of all kinds of defects and cracks. The color palette of such plaster already inspires respect, but to keep from buying can be quite high cost and the inability to apply on absolutely all kinds of surfaces. The most suitable option is for these purposes concrete.

Silicate variety

It has high quality characteristics, contains in its composition special mineral fillers, perfectly adheres to the base, so that the list of surfaces to which it can be applied is significantly expanded. The color palette allows you to make practically no problems, but you can stop the cost of the compounds. For this reason, most often it is applied locally - when decorating especially significant and prominent places of a building (columns, door and window slopes, curbs, etc.).

Silicone plaster

This "queen", as it is called by the master, is good in all respects. And it is applied on any surfaces, and its performance characteristics are stunning, colors have almost any and are not subject to deformation at all. However, due to its high cost, with external works is practically not applied. It is used most often for interior finishing works.

Types of invoices

Talking about what the plaster decorative for external works represents, one can not ignore one of its main qualities - directly the texture itself. The choice of its entirely depends on the appearance of the finish. So, among the simplest, the façade decorative plaster "bark beetle" mentioned above is most often used for outdoor works. Next comes the "coat" (they also talked about it). Of the simplest in the third place is "lamb", after finishing which the walls look similar to the fleece. The bituminous plaster gives a finely hilly surface, and the mosaic has something like it, but is more noble and imitates the surface, as if strewn with fragments of mica or other stone. Stone creates the illusion of finishing with stone, limestone or marble. Terrazitic after application is similar to tuff. There is still a kind of "graphite", which allows you to get a very peculiar texture, but working with it is very complex and extremely expensive. And because it is used most often only when restoring historical buildings.

Now that we have sorted out the views, we will describe what the technique of applying facade decorative plaster is. However, before a few words about the preliminary work, which should definitely be done.

Substrate preparation

As we have already mentioned, preliminary work does not require much effort. Since the decorative plaster for outdoor works hides rather insignificant defects quite well, there is no need to achieve a special smoothness of the surface. But, of course, you need to repair all the significant defects and cracks, including removing the protruding fragments, as eliminating them due to the finishing material contributes to a significant overspending of the composition. Then the base surface must necessarily be primed with a view to improving its adhesive properties. There are numerous special mixtures available for this procedure. Which is better to take for this or that kind of plaster - you will tell the seller. In order to save money, you can not be too abrupt and buy a universal acrylic primer of any manufacturer. After the base surface has dried, you can start applying.

How to work with decorative plaster

Before you talk about the technique of application, it is worth pointing out a few nuances. First of all, the whole mixed solution needs to be produced at a time. If it begins to dry out, then it is strictly forbidden to breed it with water. Before mixing, the bag with dry plaster should be shaken well, so that the fractions settled during storage at the bottom are evenly distributed throughout the composition. This is facilitated by thorough mixing while preparing the solution. By the way, ready-made compounds must also be carefully mixed before starting work. And further. Try to apply a solution in a literal sense from corner to corner. If it is very necessary to take a break, then "dock" the layers can only be until the first is finally dried. Otherwise, the transition will be noticeable.

Technique of application

The prepared mortar is spread with a spatula on the wall section to be treated, and then the trowel is stretched over the surface for a more uniform application. The thickness of the layer should correspond to the size of the fractions of the composition, which, as a rule, is indicated on the package. Immediately after it has dried, for which it takes no more than ten minutes, a plastic trowel performs the formation of the desired image. That is, the tool is moved in the chosen direction - up-down, forward-backward, in a circle or at a given angle. If necessary, after complete drying, it is possible to clean out the problem areas with sandpaper, however, when finishing the facades, no one conducts such work. Correction is used only for internal works.

Conclusion

Textured plaster - a great material for finishing the exterior facades of buildings. And if necessary, such work is strongly recommended to pay attention to it. The only thing that should be considered in this case is the need for appropriate skills. Sometimes it is not always advisable to conduct such work independently, taking into account the scale. Sometimes it is better to seek professional help. Especially if it was not simple, but more expensive decorative plaster for outdoor works that was bought for decoration. The cost of work is, depending on the region, an average of about three dollars per square meter. M.
