External silicone plaster

Thin-layer next generation plaster based on silicone resin (organosilicon), composed of selected grains with microfilaments added in order to improve its resistance to cracks. Can be used both indoors and outdoors. Dried plaster creates a hydrophobic and permeable coating, protecting the building against moisture penetration and providing removal of water vapour (breathing). The abrasion resistance of the coating is improved as well. The plaster provides very good adhesiveness and optimal resistance to aggressive atmospheric conditions.


Exceptionally resistant to urban pollutants, provides long-lasting durability and good condition of decorated surfaces. Due to its characteristics, it can be applied to old surfaces or walls insulated with mineral wool, reinforced layers of thermal insulation, polystyrene foam, concrete, cement plasters, and other mineral substrates. Intended for modern buildings, historic tenements, office buildings, stylised buildings, manors, blocks of flats, sky scrapers, etc. Provides maintenance of diffusivity when used in eco-friendly systems, which is crucial to maintain the climate in our homes.


  • waterproof,
  • water vapour permeable,
  • a wide variety of colour is available,
  • resistant to microcracks and abrasion,
  • compatible with all insulation systems,
  • resistant to UV radiation, ensures colour durability,
  • enables you to keep the building fresh for more time,
  • highly resistant to dirt and atmospheric agents,


When selecting colours for a given interior, several factors must be taken into account as they affect our perception of the colours, aesthetics, and our mood. The swatches and the catalogues available on the market are for illustration purposes only, frequently in the form of a photography of the colour printed on single quality paper (glossy or matt) and do not represent the actual perception of the final effect. ECORSON produces original colour and texture samples of individual products to make the choice easier. Keep in mind that small, ready colours or textures in swatches may slightly differ visually from final effects in particular interiors. If you lack colour intuition, we recommend making a larger sample or hiring a Designer or Decorator who can suggest individual and appropriate choices. Keep in mind that the colour on a small swatch (even an original one) may look different on a large surface due to a number of factors such as other nearby colours that dominate the room (barely visible colour of glass panes, floor, furniture, etc.), the amount of sunlight and the time of day, direction, the type of artificial light (warm or cold, scattered or beam), and distribution of the colour. The same rule applies while selecting colours and painting outdoors as we are close to nature and affected by it. All these factors saturate the walls with their colours, tones, and shades (and vice versa), interfuse, and create collages, often beautiful. It must be taken into consideration when selecting colours. Our perception of colours is significantly affected by light. We do not recommend applying two different colours or products on corners as the colour should be determined by the shape. Have fun with colours and textures, remember that they can change a lot in our interiors, for example affect the perception of size and distance, add warmth and cosiness, or create a cold and fresh appearance. The colour and the texture may cause desired feelings and affect our mood. As it is our passion, we wish to share it with you. ECORSON team.

General application principles

All work on a given substrate should be performed and finished with products from the same production batch, with the same serial number, as there may be slight differences in the base that may affect the final colour and effect. The instructions to perform the work in a professional manner are based on basic occupational health and safety rules, and guidelines described in the following sheets: technical, application system, adapting work to conditions (i.e. temperature, humidity, drafts, etc.), and proper surface preparation.

Before we begin painting, it is very important to verify the technical condition of the substrate and follow the guidelines related to its proper preparation. The substrate should be: stable, dry, cleaned, all cavities should be filled and any fungi should be removed if necessary. Dust must be removed from the surface, as well as any built up dirt and grease. If the surface does not meet the requirements, old layers of paint, which should adhere to the substrate well and endure the adhesiveness of the new finish, must be removed mechanically. When working on mineral textures that have never been painted, ensure they are clean and free of defects (new plasters should be painted after 3-4 weeks of stabilisation or after the time indicated by the producer of the plaster, putty, filler, etc.)

In order to achieve a level and homogeneous surface on a given substrate, the work should be performed by a single person using the same tools, with a short application time (without pauses) for each coat so the whole wall may be covered with wet paint.

The final effect depends on the user's skills, tools, and the amount of product applied. Therefore, the efficiency, samples, and other parameters presented here are illustrative and approximate only, calculated based on several years of experience and research, applicable to optimal climatic conditions (approx. +23°C and 65% humidity). The parameters may change in other conditions. However, due to a great variety of substrates and application conditions, it is necessary to verify the product and its effectiveness by testing it individually under given conditions.

If the surface requires washing, the whole wall must be washed with similar motions and using the same tools and liquids. Wash the tools with water immediately after use. ECORSON is not responsible for non-intended use of the product and uses inconsistent with the principles, also when used beyond our reasonable control.

Ecology: does not contain lead, chromium, and mercury. Does not require any marking to identify toxicity or danger to human health in accordance with CE standards and classification.
