ATLAS DEKO M is a line of mosaic renders made of advanced base: mix of acrylic water dispersions, hydrophobing agents, modifiers and specially selected natural and dyed aggregates (depending on the expected colour composition).
ATLAS DEKO M forms light and durable rendering coat of improved resistance to washing, cleaning and scrubbing.
Rich colour palette – can be applied on various substrates, gives unrestrained offer of designs of walls at exhibition halls, car showrooms, offices, flats, staircases, waiting rooms, halls, antechambers, façades of residential and public access buildings, etc. Mosaic renders TM 1 can be enriched with mica or brocade which strengthen their decorative effect.
Great flexibility, resistance to mechanical damage – can bridge thermal stress and mechanical impacts owing to high content of specially selected dispersions of polymers. The render perfectly compensates stress resulting from thermal expansion of layers located beneath which can occur, for example, in strong sunlight.
Great operational durability – owing to the use of mix of acrylic dispersions, special admixtures and modifiers the product offers:
-          improved coat durability,
-          improved resistance to atmospheric factors and UV radiation,
-          improved resistance to growth of microorganisms,
-          long term aesthetic façade appearance.
BIO PROTECTION – high grade of hydrophobisation and very high content of shell-active capsule substances eliminate threat and form unfavorable conditions for growth of fungi, algae and lichen on the rendering coat surface.
Great surface hydrophobisation, self – cleaning ability – greatly UV – resistant hydrophobic layer efficiently reduces structural coat absorptiveness and allows for durable hydrophobing effect which prevents dust and dirt particles adhesion and allows for their possible wash off during precipitation.
Dark and intensive colours – dyed natural quartz aggregate used in the product offers wide range of choice and design modification. Therefore, it gives rich colour pallet, also with dark and intensive shades, which meets trends and needs of users.
Great shade durability – owing to the use of aggregate dyed with polyurethane resins and special hybrids of inorganic and organic pigments of improved resistance to external factors.

Substrate preparation
The substrate should be:
stable – sufficiently rigid and appropriately long stabilized and primed,
even – irregularities and gaps should be filled with, e. g. ATLAS ZW 50, ATLAS ZW 330, ATLAS CEMENT PLASTER or adhesive mortars used for application of base coats of thermal insulation systems; prime the surface with ATLAS UNI-GRUNT emulsion before the substrate repairs (NOTE! By virtue of fine aggregate, special attention should be paid to the substrate evenness as any irregularities will be transferred on the rendering coat surface),
clean – free from layers which would impair render bonding, especially dust, dirt, lime, oil, grease, wax, residues of oil and emulsion paints; substrates infected by biological corrosion (fungi, algae, etc.) must be cleaned with ATLAS MYKOS agent.

**) it is advisable to use ATLAS CERPLAST of recommended colour (table with appropriate priming mass colour can be found in IMPORTANT ADDITIONAL INFORMATION section)
Plasters applied beneath ATLAS DEKO M should be floated rough, do not extract “bleed” water in case of gypsum plasters. If gypsum plaster was classically grinded during application its surface should be made matt.
Render preparation
ATLAS DEKO M – type TM 1
The set consists of two components:
-          component A – aggregate in bags (8 colours, bags 5.4 kg)
-          component B – base in a bucket (4.6 kg or 7.6 kg)
The rendering mass is prepared with the use of three bags of aggregate, which should be poured into a bucket with base and mixed (the total weight of aggregates poured into a bucket with base should be 16.2 kg). So prepared render should be mixed thoroughly.

The render TM1 it is possible to modify the composition with silver brocade or black mica. Note: it is possible to use only one of additives in one rendering mass. Mica or brocade can be added at the stage of render or mass preparation. Pour the whole package of additive into a bucket with base or a bucket with previously mixed rendering mass. In the second case the whole mass should be thoroughly stirred again so the additive is uniformly distributed within the mass.
Mass preparation
Preparation of rendering mass
The mass should not be mixed with other materials, thinned or thickened. Stir the mass directly before use in order to unify its consistency.
Mass application and render smoothening
Apply the mass with a smooth stainless steel trowel (standard or venetian one), keep the coat thickness same as the aggregate grain size, smoothen in one direction simultaneously. Lead the trowel at the possibly smallest angle against the smoothened surface in order to avoid slight irregularities. Collect excessive material back into a bucket and remix.
NOTE! By virtue of fine aggregate irregular substrates may require two coats of render. The second coat should be applied when the first one dries, i.e. after approx. 24 hours. Irregular smoothening (particularly when using additives) can cause local differences of shade of the rendering coat.
In order to form additional visual effect, one can use self-adhesive cardboard templates (available on custom order). The template projects shape of natural stone or brick on walls. In order to strengthen the effect formed with a template, it is recommended to use ATLAS DEKO M and ATLAS CERPLAST priming mass of contrastive shades.
When the priming mass dries, stick the templates upon the wall, make sure they adjoin precisely and bond well to the substrate. Next, apply ATLAS DEKO M render as described above. Just after the render application and smoothening, remove all the templates – ATLAS CERPLAST will imitate grout between surfaces imitating stones.

• After application the render shows milky-white colour and gets proper shade after drying. High air humidity and low temperature can extend the time of setting and can cause change of the colour shade.
• At constant contact with water, the render can get milky-white top coat which disappears when the render surface dries. It is not recommended to apply the render upon surfaces exposed to prolonged water or damp action (e.g. on horizontal surfaces or those with slight slope, in ponds, etc.) or on elements without appropriate damp proofing.
• In order to avoid differences in colour shades:
- an individual surface should be coated with render of the same manufacturing date,
- when a composition requires same aggregates from a few bags, they should be of the same manufacturing date,
- an individual surface should be coated during one technological cycle,
- the mass should always be stirred before use.
• The maximum surface possible to coat during one technological cycle (application and smoothening; for particular substrate type and weather conditions) should be established experimentally.
• Apply the render on adjoining application areas with the “wet on wet” method, prevent the smoothened rendering coat from drying. Otherwise the seams will be visible. Technological breaks have to be planned in advance, e.g. in corners and angles of a building, under rainwater pipes, on lines of contact of two colours, etc.
• Protect the rendered surface, both during mass application and drying, against direct sunlight, wind and precipitation.
• Obligatorily use scaffolding covers (mesh) for application outdoors. If air and substrate temperature just before application and during the render drying exceeds +25°C, then the application should be limited to early hours only. Non-conformance with these guidelines may lead to insufficient binder transparency at points exposed to strong sunlight or direct action of temperature higher than accepted in this data sheet.
• Time of drying depending on substrate type, temperature and relative air humidity is approx. 24 hours. In high humidity and temperature close to +5°C the time of drying can be longer.
• Tools must be cleaned with clean water directly after use. Difficult to remove residues of the set mass can be removed with ATLAS SZOP 2000 agent.
• Aggregate should be transported and stored in sealed original and labeled packages in dry conditions, most preferably on pallets. Avoid direct sunlight. Keep in dry, cool and well ventilated room, away from incompatible materials, beverages and food. Protect against humidity.
• Base and ready-to-use render should be transported and stored in cool, dry, well ventilated room in tightly sealed, labeled original container. Protect against direct sunlight, sources of heat, hot surfaces and open flame. Temperature of storage: from +5°C up to +30°C. Protect against freezing. Stir before use. No negative interaction known when conditions as above are kept. Render shelf life is 12 months from the date of the base manufacturing.
• Harmful to aquatic life with long lasting effects. Keep out of reach of children. Read label before use. 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.
