Silicone plaster: material features
It so happened that in the heads of people stucco is associated with something gray and nondescript, and such stereotypes were not formed from scratch, a couple of decades ago stucco mixes were limited only to cement, from which it is difficult to make something masterpiece. But today, everything has changed and in this article I would like to talk about what silicone plaster is, and why builders and homeowners prefer it more and more.
The content of the article
What it is
The main nuance that distinguishes decorative silicone plaster from its competitors is the binder in the composition, which is natural silicone, and as a result, the entire set of positive qualities is transferred to the plaster mixture.
It is worth noting that the qualities that are inherent in silicone plasters are unique and cannot be found in other mixtures. Of course, this adds up to the price of this material, but if it is necessary to repair the facade for many years to come and not restore the coating every five years, then silicone decorative plaster is an ideal choice.
We list only the most basic nuances, since a full article will take a separate article:
- High adhesion to any surface.
- Resistance to all types of precipitation and natural influences.
- UV insensitivitythat do not burn out the dye in the composition.
- Decorative silicone plaster can be applied even at sub-zero temperatures and at high humidity.
- High ductility of siliconeshown in the photo at the beginning of the article allows you to apply the plaster in a very thin layer and even with your own hands without the appropriate experience.
- A wide variety of colors for silicone plaster allows you to create a unique design, and a combination of colors and textures will make it unique.
- High vapor permeability, a layer of plaster lets steam out, but at the same time prevents it from getting inside.
- Most manufacturers add special additives to silicone plastersthat prevent the formation of fungus and mold.
- It is very difficult to damage silicone plaster mechanically.
As you can see, there are a lot of positive qualities, and some of the above are inherent only to silicone-based plasters.
Advice! When buying plaster, you should always ask the seller for supporting documentation in the form of quality certificates and Rostest documents, since due to the high cost these plasters often become an object for fakes.
Of course, one cannot ignore the negative aspects of this material, since the ideal finishing material has not yet been invented, especially if we talk about facade decoration, which every day experiences a whole range of effects.
- High cost of material, which was already mentioned above.
- Difficulty removing obsolete cover if necessary.
- High probability of acquiring fakesand which will negate all efforts to create a high-quality and durable coating.
Also, as a drawback, we can highlight the fact that under the silicone plaster you need to carefully prepare and level the surface, since it is applied with a thin layer, and all the bumps will be on the face. Although this concerns only the issue of saving material, since there are no restrictions on the thickness of the layer, and in principle it is possible to remove unevenness with the help of washed plaster, if the financial side is not so important.
Features of working with silicone plasters
Ready-made silicone plaster is supplied in buckets and does not require additional dilution, which may be necessary only if the mixture dries, then just add water and mix the solution using a mixer at the lowest speed.
Advice! Silicone finished plaster is diluted with water, and it is best to use purified water for these purposes, since flowing from the tap may contain iron particles, which subsequently begin to oxidize and give yellowish spots that cannot be removed.
More detailed instructions for the dilution of silicone mixtures are indicated on the packaging, the entire application process is described there, which differs little from the application of other types of plaster. Differences can only affect a combined type, such as silicate-silicone plaster, which hardens very quickly, and all work must be carried out at an accelerated pace and preferably not alone.
Create a texture pattern
From silicone plaster, you can create any texture patterns, and, by the way, the famous Venetian plaster - This is also most often silicone.
The most common textures used in the decoration of the facade are:
- Bark beetle (see Decorative plaster bark beetle: material features) A texture imitating a tree bark, eaten by bugs.
- Lamb (see Plaster front Lamb - a practical "clothing" for your home) or fleece, a pattern resembling curls of lamb wool.
- Fur coat (see Fur coat plaster: rules for applying), the most popular pattern used on facades for more than a decade.
In addition, silicone plasters can be with the addition of natural stone chips, and such a coating can mimic marble or granite in its natural manifestation. Such a coating with a different-sized fraction is considered the most durable and stable, since silicone acts only as a binder component here, and it is stone elements that create strength.
As for the Venetian silicone-based plaster, I rarely use it on facades, although the strength and stability of the finished coating allow this to be done. The point here is more in the aesthetic component, since the Venetian plaster has a very small pattern, then over a large area of the facade, it will simply be lost.
If there is a desire to create a unique facade, then you can use decorative painting, which is done using acrylic or silicone dyes on your own or using a stencil.
Advice! Before applying the drawing to the facade, it is better to make a full-scale simulation on a computer in order to clearly understand how it will look.
And how to create drawings on silicone plaster, you can see the video in this article.
Work with silicone plasters
The first and most important point in working with any plaster mixes is the preparation of the surface, it is from this that the whole quality of the coating will depend.
Dust, dirt and oil stains should be removed from the walls, if any.It is oil stains that can violate the integrity of the coating, since they create a film between the surface and the coating, and in this place, sooner or later, cracking and peeling will begin.
To be sure, the cleaned surface can be additionally primed, although in the case of silicone plasters, this is not necessary, since they already contain antiseptic additives.
The plaster is applied with a spatula from the corners and to the center, the surface can be smoothed with a construction trowel, and giving an additional texture pattern can be done using a roller with fur skin or special applicators that have a relief surface, which leaves an imprint on the still not frozen layer of plaster.
Due to the fact that silicone plaster does not change color when dried, the entire process of facade decoration can be divided into several stages, and all work should be done alone and gradually, and this is another indisputable plus that decorative silicone plaster has.
Silicone plaster Farbe "Bark beetle"
Silicone plaster “Bark beetle” Farbe– material for decorating the facade of buildings. Such a product improves the appearance of the structure, improves heat and sound insulation, as well as other operational characteristics.
Structure
Plaster Farbe "Bark beetle" contains the following components:
- Silicone additive. It is responsible for moisture resistance, elasticity and protection from exposure to sunlight.
- Faceted marble chips. It improves the properties of the product without disturbing the coating structure due to the spherical shape.

- Functional supplements. Enhances product properties.
Material properties
Farbe Bark beetle silicone plaster has the following properties:
- lack of cracks after hardening thanks to a silicone basis;
- vapor permeability - allows air to circulate, which prevents the formation of condensation under the coating and the occurrence of mold and fungus;
- resistance to sudden changes in temperature;
- moisture resistance - protects the building base from the harmful effects of precipitation;
- resistance to sunlight, so that the appearance of the finish does not change over a long period;
- frost resistance;
- “Clean facade” - the material cleans itself under the influence of precipitation.
