Main properties

  • highly vapour permeable
  • low water absorptiveness
  • resistant to dirt
  • high adhesion to the substrate

Main parameters

  • consumption: ca 2.5 - 3,0 kg for 1 m²

Thin-coat render for finishing the façades with a decorative spotted texture.
For indoor and outdoor use.
Recommended for surfaces insulated with EPS, XPS or mineral wool.
For façades where it is crucial to maintain high vapour permeability of the partitions – perfect for buildings made of cellular concrete, walls of old buildings, swimming pools or kitchens.
Types of rendered buildings – detached houses, apartment buildings and industrial or public access buildings.
Types of substrates – concrete, traditional plasters on walls made of bricks, blocks and ceramic, cellular concrete or silicate hollow bricks, plasterboards, base coats of thermal insulation systems with EPS, XPS or mineral wool.

Up-to-date thin-coat render, based on an unique combination of organic and mineral binders.
Characterised by very high vapour permeability assisted by low water absorptiveness and,  typical for pure silicone renders, great resistance to dirt.
Enables to achieve dense and very clear spotted texture up to 1.5 mm or 2.0 mm.
BIO PROTECTION – creates unfavorable conditions for fungi and algae growth due to its low water absorption and acid-alkaline reaction.
ELASTICITY AND STRENGTH – formula, which ensures better elasticity and resistance to impacts, leads to the compensation of tension when the surface of the render is hit, making it consistent and not chipping off.
COLOUR DURABILITY – advanced technology provides colour durability thanks to the application of modern pigments, computer controlled system of dozing and permanently supervised manufacturing process – the render keeps its initial colour, is more resistant to bleaching and UV rays.
ENVIRONMENTALLY FRIENDLY – render recipe was designed regarding the sustainable development aspects: maximally reduced amount of volatile organic compounds and use of natural fillers only.
increased resistance, achieved due to the presence of dispersed microfibers that reinforce the render in the entire volume – render is protected against possible cracks caused by the tension and alternate surface heating and cooling.
400 colours  – in accordance with Renders and Paints SAH Colour Scheme

Substrate preparation
The substrate should be:
• stable – sufficiently rigid
sufficiently long stabilized  – The assumed stabilizing time for substrates is, respectively:
− for new cement plasters from ready to use ATLAS plastering mortars, min. 1 week for each 1 cm of thickness,
− for concrete walls - at least 28 days,
• dry,
• even – fill in larger irregularities and cavities with ATLAS LEVELING MORTAR, ATLAS ZW 330 or ATLAS PLASTERING MIX, or adhesive mortars for the execution of the reinforced layer in thermal insulation systems. Before repair, prime the surface with ATLAS UNI-GRUNT emulsion,
• clean – free from layers that can deteriorate the adhesiveness of the render, especially dust, dirt, lime, oil, grease, wax, residues of oil and emulsion paints; a substrate covered with algae, fungi, etc. must be cleaned with ATLAS MYKOS agent,
• primed – with ATLAS SILKON ANX.
Rendering mass preparation
The render is delivered as the ready to use mix. It must not be mixed with other materials, diluted, or thickened. Mix the contents directly before application to equalize the consistency.
Render application
Apply the render in a layer equal to the aggregate grain size, with a stainless steel float. Remove the excess of the material, place it in the bucket and remix.
Texture forming
The freshly applied coat requires texture forming with a float made of plastic. The spotted effect is obtained by floating the plaster with circular movements.

Average consumption (depends on a substrate and render type):
− ca 2.5 kg for 1 m2 for N-15 render.
− ca 3.0 kg for 1 m2 for N-20 render.
The exact consumption volume can be established following a test carried out on the rendered surface.

• ATTENTION! Bucket with a silicone-silicate render, apart from a description placed on the identification label, is highlighted also with an orange lid.
• The maximum surface possible for rendering in one technological cycle (application and floating) must be established experimentally (for the given type of substrate and weather conditions).
• Apply the mass using the “wet on wet” method, preventing the floated layer from drying before applying the next layer. Otherwise, the seams will be visible. Technological breaks have to be planned in advance, e.g. in the corners and angles of the building, under rainwater pipes, or place of contact of two colours, etc.
• Protect the rendered surface both during work and while setting against direct sunlight, wind and precipitation.
• The setting time, depending on the surface, the temperature and the relative humidity of the air, is from 12 to 48 hours. In elevated humidity conditions and the temperature ca. +5°C the setting time can be extended.
• In order to avoid differences in colour shades while applying silicone render, cover one surface with the render of the same manufacturing date.
• When using the renders on thermal insulation systems, avoid dark colours with diffused light reflection coefficient less than 20%. The share of renders of such colours in the surface of the facade should not exceed 10%.
• The tools must be cleaned with clean water directly after use. Difficult to remove residues of the set render can be removed with the ATLAS SZOP 2000 agent.
•Harmful to aquatic life with long lasting effects. Keep out of reach of children. Avoid release to the environment. Dispose of contents/ container to appropriately labeled containers designed for selective waste treatment, emptied by an authorized company. Follow the instructions of the Safety Data Sheet.

Keep in tightly sealed original and labeled containers. Keep in dry and cool places, protect against overheating (> 30 °C) and freezing - the product freezes and irreversibly loses its performance in temperature below 0 °C. Protect against direct sunshine. Incompatible materials: avoid contact with aluminum, copper and alloys of these metals. Shelf life in conditions as specified is 12 months from the production date shown on the packaging.
