|
| ATLAS CERMIT N is thin-layer structural renders designed for manual preparation of decorative external and internal plaster coatings. It can be used on all even and structurally sound mineral substrates such as concrete, traditional cement plasters, cement plasters, plasterboard panels and reinforced layers in the following thermal insulation systems: ATLAS, ATLAS STOPTER K-10, ATLAS STOPTER, and ATLAS HOTER. |
 |
|
| ATLAS CERMIT N is ready-to-use render (in paste consistency) based on water dispersion of synthetic resins and dolomite aggregate with grain size: up to 1.5 mm N-150; up to 2 mm N-200; and 3 mm for N-300. ATLAS CERMIT N is efficient, convenient and easy to use. When dry it provides hydrophobic layer permeable for water vapour. It is very resistant to various damages, weather, washing, etc. Moreover, ATLAS CERMIT N contains organic agents that reduce fungi and mould development on render surface. ATLAS CERMIT acrylic renders are available in 655 colours in the NEW ATLAS COLOUR PALETTE. |

| The substrate should be stable, even and structurally sound i.e. strong enough; it should be free from anything that may weaken adhesion, in particular dust, dirt, lime, oil, grease, wax, remains of emulsion and oil paint. Remove existing paint and render coats of insufficient adhesion. Afterwards, prime the substrate using ATLAS UNI-GRUNT. Fill in irregularities and defects using e.g. ATLAS LEVELLING MORTAR, ATLAS PLASTERING MIX or ATLAS REKORD finishing mortar. Before render application, regardless of substrate type, provide a prime coat made of ATLAS CERPLAST priming mass. |
|
|
| ATLAS CERMIT N is ready to use. It may not be combined with other materials, diluted or thickened. Immediately before application, stir it in order to achieve homogenous consistency. |
|
|
| Apply ATLAS CERMIT N and R over prepared substrate as an even layer using a float made of stainless steel. Thickness of the layer should correspond with the aggregate grain size. Remove excess of material, place it in the bucket and mix. Form texture of the surface using a float made of plastic with circular moves. Open time of the mass (between mortar application and floating) depends on substrate absorptivity, ambient temperature and mass consistency. Experimentally (for a given type of substrate and given weather) determine the maximum area that can be prepared in one technological cycle (application and floating). Apply the mix using the “wet on wet” method, preventing one batch from drying before application of another one. Otherwise the “seams” will be visible. Plan technological gaps in advance e.g. in corners or building angles, under rainwater pipes, etc. Protect the plastered surface during work and when it dries from direct sunlight, wind and precipitation. Drying time depends on the substrate, temperature and relative humidity of air and is from ca. 12 to 48 hours. In case of increased humidity and temperature ca. +5°C, render setting time may extend. Substrate and ambient temperature during work and when render dries should be from +5°C to +25°C.
Note: to avoid differences in colour shades in case of colour acrylic renders, apply render of the same production date on the same surface. If the renders are used in thermal insulation systems, avoid dark colours with reflection coefficient of scattered light below 20%. Share of the renders in such colours should not exceed 10% of façade surface.
The information comprises basic instructions of product application and do not relieve users of responsibility for work in accordance with good construction practice and OHS regulations. |

On average, ca. 2.5÷2.8 kg of N-150 render is sufficient for 1 m2
ca. ca. 3 kg of N-200 render is sufficient for 1 m2
ca. ca. 4.0÷4.5 kg of N-300 render is sufficient for 1 m2
The exact amount of mix used can be determined in a test conducted on the plastered substrate. |
