Silicone plaster: description, types, application technique

Today, domestic craftsmen are striving to perform many types of construction and finishing works on their own, or, as is now customary to say, with their own hands. Whether the services of professionals are really hitting their pockets, or men finally remembered "who's the boss", it's hard to say. However, the fact remains. While on the market at the present moment, almost every day there are new items, from the variety of which it's time to get lost in the mathematician, not that not yet fledgling, but zealously bursting into the fight to the domestic master. And so very often owners of apartments and houses are in search of information about a particular technology or modern material that will make repairs quickly and efficiently. We, in turn, will try to help in this matter now and tell in detail about what silicone plaster represents. And in passing, we will reveal the main secrets of the technique of its application.

What is this material?

The word "plaster" in many immediately associated with dull black-gray walls of the room, more reminiscent of the kind of utility room than a living room. This is partly true. But this applies only to the variety of this material, intended for rough finishing. The heroine of our review belongs to a very different class. This is the finish material. That is, silicone plaster is used only in the final finishing process. And both outside and inside. Although initially the composition was supposed to be used only for decoration of facades. And not only what, but historical buildings. However, the material turned out to be so good that it was used to finish first the facades of houses and buildings, and afterwards for internal premises. What, in fact, is the secret? In the fact that silicone resin is added to the usual plaster mix , which is mixed with various fillers like mineral materials, fabrics, etc. The fact that the surface is treated depends on what is used as additives.

By the way, some experts call this mixture just the queen of plasters. Which, in principle, is true. As evidenced by its characteristics, which will be discussed further.

The main advantage

As a rule, finishing works are conducted in several stages. First goes rough, which is preparatory and is aimed at leveling the surface and as much as possible to close all existing defects. All this requires not only time, but also material costs for the purchase of various compounds, which today are quite expensive. Silicone plaster - for the facade or for interior works, it does not matter - allows you to do everything at the same time. That is, it even outlines the surface, and it will give the desired decorative effect. What, you will agree, is very important for today. In addition, silicone plaster is sold in containers of various volumes, which allows you to choose the appropriate dosage for yourself and not throw away extra money. Since the cost of the material is quite high. Which, by the way, unfortunately, is its drawback. True, the only one. In the rest - only solid pluses. On the positive characteristics of silicone plaster - further.

Benefits

An undoubted advantage of the composition can be considered a long term "life". For example, silicone facade plaster can not lose its attractiveness for twenty years. And this despite the fact that the building is constantly exposed to atmospheric precipitation, constant temperature changes. And inside the room it will look as if it was applied only yesterday, even longer.

Silicone plaster has the highest level of vapor permeability, due to which the material is able to provide the necessary microclimate in the premises exposed to moisture. On the walls will not form condensation, mold, they are not afraid of fungus. That's why silicone decorative plaster is great for finishing kitchens, baths, dressing rooms.

The material is endowed with excellent elasticity, so that in the event of any changes in the structure of the treated surface, it will not lose its integrity. To put it simply, the cracks and other defects that have appeared over the years will simply not be visible.

Plaster, thanks to its composition, does not attract dust and dirt, does not require special care. It is enough to wipe it with a damp rag.

You can apply this excellent material yourself, without resorting to the services of professionals. If there are, of course, at least minimal skills in this matter. If the home master has never held a spatula in his hands, then it will be difficult to cope with the work, especially when it comes to finishing the facade.

Silicone plaster can be either white or already tinted. So you can choose the right shade without any problems. In addition, it can be painted, which is also an indisputable plus. And one more advantage. With its help you can create different surface textures. It all depends on the type of finishing material purchased. This is in the next section.

Types of silicone plasters

Depending on what is obtained after applying a decorative structure to the surface, silicone plaster can be divided into several types:

• Stucco "Bark beetle". After applying it to the wall, it is possible to obtain a surface striated by a different kind of grooves.
• Silicone pebble. Gives a surface that looks like a marble crumb.
• The "lamb". Something like a fleece.
• The Venetian. The decorative effect obtained after its application, resembles a marble coating.
• Silicate-silicone plaster is a kind of silicone that is of all the types described above, but differs from the "heroine" of our review by higher performance characteristics and increased resistance to low temperatures due to the addition of liquid potassium glass.

About the first form, as the most popular, and the last, as a variety, - further.

"Bark beetle"

The most popular among all available on the market of finishing compounds is used plaster "Bark beetle". Its silicone variety is not the only one, there are also the same mixtures on a cement, acrylic, gypsum base. However, the polymer is still preferable in that it has all the advantages of the silicone compositions described above. In addition to the main ingredients inherent in such a mixture, "Korode" contains additives of mineral origin (onyx, quartz, marble, etc.) of various fractions - from one and a half to three millimeters. Depending on the size of the inclusions, the final texture of the surface also varies. The fraction is larger, the brighter the effect obtained.

Excellent for both external and internal decoration. In addition, it is often used to decorate heat-insulating foam plates.

Silicate-silicone decorative plaster

This composition can be successfully applied in both external and internal decoration. However, the silicate variety, as mentioned above, is characterized by increased strength characteristics, therefore, it is most often used for the decoration of facades. Resistance to weathering and all kinds of pollution, stunning color fastness in combination with increased hydrophobicity sometimes make it an indispensable material when decorating the exterior surfaces of buildings. However, such silicate-silicone plaster - for the facade decoration is quite expensive because of its high cost. Therefore, when deciding on the use of this finishing material on large areas, it is necessary to carefully calculate its feasibility.

Manufacturers

Silicone plaster produced by many manufacturers. However, experts note that the best in this regard are several firms.

A good finishing material is supplied by Knauf. Silicone plaster from this manufacturer is characterized by ease of application, good performance characteristics, safe for human health composition. The most popular brands are Knauf Conni S, Knauf Kati S and Knauf Add.

A good material is supplied to the market and the domestic company "Bolars". Silicone plasters of this manufacturer are of high quality in combination with a fairly affordable price. The most popular brand is Bolars Mineral-S.

However, the most popular is the Ceresit silicone plaster. This composition is preferred by most masters. About it - more details below.

"Ceresite"

Brand is not in vain so popular. Silicon plaster "Ceresite" is literally created for the solution of almost any problems. The manufacturer produces its products in finished form, in containers of 25 kg. On the market from the brand are all available varieties of silicone plaster, so that it will not be possible to find the right composition for yourself. In addition, the manufacturer delivers to the market products are not a universal plan, but divide it into a finishing material for external and internal works. This allows you to save on cost, as the prices in both cases are somewhat different.

Plaster is very easy to apply, even a master craftsman, who is not quite sophisticated in the finishing process, will be able to cope with the work. This also explains the relevance and popularity of such finishing material, as "Ceresite" silicone plaster. Instructions for use and application - very detailed and understandable - are contained on each container. So it's really easy to work with her.

But what is the technology of application - further.

Preparation

As already mentioned, careful leveling of the surface is not required. However, the preparatory work will still have to be done. The main requirement: the walls should be as clean as possible, that is, you need to get rid of any coating on them in the form of wallpaper, whitewash, paint, as well as all kinds of pollution. Cracks and large defects must be repaired. And most importantly - the surface needs to be treated with a primer for silicone plasters. Then leave for a day to completely dry.

Technique of application

By and large, the work with the silicone compound does not differ much from those with conventional plaster mortar. Except for a few nuances. First of all, it is worth remembering that, despite the fact that the mixture is already sold ready-made, it must be mixed before consumption. When applying, use a metal spatula, which is recommended to keep the surface strictly at an angle of 60 g. As for the thickness of the layer, it must strictly correspond to the size of the filler fraction. After drying, it is necessary to form a structure with a plastic float. Moving it in a circle, as well as up and down, you can make a different pattern.

To get a uniform surface, you can not throw the rest of the mixture off the spatula back into the bucket with the mortar. We must try to work out everything that is applied to it. Silicone plaster in no case can not be wetted with water. All work on one wall should be done in a continuous manner.

Conclusion

Today silicone plaster is really an innovative material that allows to get a beautiful decorative surface with excellent performance characteristics. The composition is excellent for both external and internal decoration, it does not require special skills when applied, it has a long service life and is undemanding in care.
