Decorative and protective finishing of façades and internal walls.
Light and durable render – it is an ideal finish for thermal insulation systems on all types of buildings.
Recommended for buildings exposed to algae and fungi – situated close to clusters of greenery and water reservoirs; high pH (~12) hinders the development of biological corrosion appearing in the form of brownish-green deposit resulting in damage to the surface.
Types of rendered buildings – detached houses, apartment buildings and public access buildings. Types of substrates – concrete, traditional plasters on walls of bricks, blocks, or ceramic, cellular concrete or silicate hollow bricks, plasterboards, thermal insulation systems with EPS, XPS and mineral wool. |
Resistant to micro-cracking – contains special fibres reinforcing its structure.
Durability parameters meliorate in use - thanks to the positive influence of natural carbonation process of mineral renders, which limits their absorbability, hardens structure and improves resistance to chemical aggression.
High durability and hardness – owing to the polymer - reinforced mix of binders – white, fine, high grade cement type and lime, and also due to the specially selected quartz aggregate.
Hydrophobic layer – the content of hydrophobic agents reduces the absorbability of the render and protects the partition against the effects of precipitation.
Protected with MYCO PROTECT system – based on biocides system guarantees long time effective protection against biological corrosion, i.e. development of fungi and algae on the surface of the render.
Does not attract dust, dirt and pollen from the environment.
Non-flammable – in combination with mineral wool it forms a non-flammable thermal insulation system on walls.
After setting, does not require painting with equalizing paint in order to equalize the colour.
Suitable for machine application with a special plastering unit – the efficiency and the speed of application increase, especially on curved substrates and surfaces of irregular shapes. The machine method can be used for the application of CERMIT SN 15 and CERMINT SN 20 only. Note: machine applied render forms a spotted structure different from that obtained with manual application.

• The open time (between the application and the floating) depends on the absorbability of the substrate, the ambient temperature and the consistency of the render. 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 render 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 substrate, temperature and relative air humidity, is from 12 to 48 hours. The substrate temperature during work and render setting must be between +5°C and +25°C.
• In order to avoid differences in colour shades while applying mineral render, cover one surface with the render of the same manufacturing date.
• 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 agent.
• Irritant - contains cement. Irritating to respiratory system and skin. Risk of serious damage to eyes. May cause sensitisation by skin contact. Due to its form - powder, the product may cause mechanical irritation of eyes and respiratory system. Keep out of reach of children. Do not breathe dust. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Wear suitable protective clothing, gloves and eye/face protection.
