Atlas SAH-NS is a thin-coat render for the execution of the finishing coats with a decorative spotted texture. It is great solution for façades where it is crucial to maintain high vapour permeability of the partitions. Silicon-silicate render SAH-NS works perfectly on buildings made of cellular concrete, walls of old buildings, swimming pools or kitchens.

The main characteristics

  • Highly vapour permeable;
  • Low water absorptiveness;
  • Resistant to dirt;
  • High adhesion to the substrate;
  • 400 colours in accordance with Renders and Paints SAH Colour Scheme;
  • enables to achieve dense and very clear texture up to 1.5 mm or 2.0 mm thick;
  • spotted texture.

Use

  • Thin-coat render for the execution of the finishing coats with a decorative spotted texture
  • For indoor and outdoor use
  • Recommended as a finishing coat during the insulation of the buildings with the use of EPS or XPS boards as well as mineral wool panels
  • For façades where it is crucial to maintain high vapour permeability of the partitions

Types of rendered buildings

  • detached houses
  • apartment buildings
  • industrial buildings
  • public access buildings
  • buildings made of cellular concrete, walls of old buildings, swimming pools or kitchens

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 and XPS boards or mineral wool

Properties

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.

Has the ability of self-cleaning during rainfalls:
Does not require frequent preserving operations.

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.

Color 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.

Resistant to cracking:
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.

Application

Substrate preparation:
The substrate should be stable, sufficiently long stabilized, dry, even, clean and primed.

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.

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.

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 Silikon 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.

Consumption

Average consumption (depends on a substrate and render type):
» ca 2.5 kg for 1m2 for thickness up to 1.5 mm
» ca 3.0 kg for 1m2 for thickness up to 2.0 mm
The exact consumption volume can be established following a test carried out on the rendered surface.

Important additional information

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 acrylic 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.
