Product description

ELASTIFIED ADHESIVE MORTAR ATLAS is manufactured as a dry mix of high quality cement binder, aggregates and special composition of modifiers, including the polymers. Improved formula makes the product to reach the highest technical parameters within its class and is widely used in residential housing.
Its technology offers:
• wide range of layer thickness (2-10 mm), therefore enables thin coat installation of the cladding, also on uneven substrates, as well as mineral substrates levelling,
• extended open time - allows placing the tiles even 30 minutes since the mortar application – it can be once applied onto larger surface and therefore minimize the time of work,
• reduced slip, therefore enables fixing the cladding “from the top”, which helps to avoid cut-to-size tiles on exposed wall zones, • wide range of use in residential housing: bathrooms, kitchens, corridors, garages, staircases, walls and floors.

Main properties

  • for small and medium size ceramic tiles, incl. gres-porcelain and concrete ones
  • for bathrooms, kitchens, corridors, laundries, garages
  • for walls and floors
  • extended open time – possibility of bonding up to 30 minutes since the adhesive application on the substrate
  • layer thickness 2-10 mm
  • for mineral substrates floating
  • for indoor and outdoor use, at low and average operation load

Main parameters

  • consumption: approx. 1.5 kg of dry mix / 1 m² / 1 mm adhesive layer
  • bonding: min. 0.5 N/mm²
  • adhesive thickness: 2 - 10 mm

Improvement of the adhesive working parameters makes use of the mortar more pleasant and easier.
Enhancing the adhesive with plasticizing additives makes it to meet the expectation of a tiler at each stage of work.
Mixing. The adhesive is less susceptible to aeration and forms homogenous mixture – uniform in terms of distribution of the components within the whole mass volume. This property, backed up with the perfect selection of the aggregate composition guarantees the highest durability of the adhesive layer.
Scooping with trowel. The adhesive is characterized by optimum viscosity guaranteeing lossless transfer from the container onto the trowel and from the trowel onto the substrate.
Application upon the substrate. The adhesive spreads perfectly upon the surface – the bonding strength of the mortar is high enough to prevent the adhesive from “rolling” onto the trowel (for properly primed substrate).
Fixing the tile. The ideally selected viscosity allows for easier handling of the fixed tile.

Substrate preparation
The substrate should be:
stable – sufficiently sound, resistant to deformation, free from materials which would impair adhesion, stabilized.
even – maximum adhesive thickness is 10 mm, in case of larger irregularities use, e.g. ATLAS ZW 330 mortar, screeds ATLAS SMS, SAM or POSTAR.
clean – free from layers which can impair adhesion, especially dust, dirt, lime, oils, greases, wax, residues of oil and emulsion paints. The substrate coated with algae, fungi, etc. must be cleaned and protected with ATLAS MYKOS agent.
primed with:
- ATLAS UNI-GRUNT or ATLAS UNI-GRUNT PLUS – substrates of excessive or heterogenous absorptiveness,
- ATLAS GRUNTO-PLAST – if the substrate absorptivity is low, or it is coated with layers limiting the adhesion.
Detailed guidelines concerning the substrate preparation, depending on its type.

Substrate type
Fresh cement screeds ATLAS POSTAR 80, ATLAS SMS 15 or ATLAS SMS 30
Stabilized min. 24 hours; optimum moisture content < 4% by weight.
Fresh cement screeds ATLAS POSTAR 20
Stabilized min. 3 days; optimum moisture content < 4% by weight.
Other cement screeds
Stabilized min. 28 days; optimum moisture content < 4% by weight. Prime with ATLAS UNI-GRUNT or ATLAS UNI-GRUNT PLUS.
Anhydrite screeds ATLAS SAM 55, ATLAS SAM 100, ATLAS SAM 150, ATLAS SAM 200 and SAM 500
Stabilized min. 2-3 weeks; optimum moisture content < 0.5% by weight. Prime with ATLAS UNI-GRUNT or ATLAS UNI-GRUNT PLUS. If, white surface tarnish forms during drying, it should be removed mechanically (grinded) and the surface dusted. Screed grinding accelerates the drying time.
Cement and anhydrite screeds on floor heating
Appropriately heated and primed with ATLAS UNI-GRUNT or ATLAS UNI-GRUNT PLUS.
Walls made of silicate or ceramic bricks and hollow blocks, cellular concrete
Leveling coat required (plaster). Direct fixing onto rough wall is possible in case of substrate appropriate dimensional tolerance. In such case it is necessary to execute full joint wall (or re-fill the joints) and repair any gaps or irregularities with ready-to-use mortars.
Cement and cement-lime plasters made of ready ATLAS mortars
Stabilized min. 3 days* for each 10 mm of thickness; optimum moisture content < 4% by weight.
Other cement and cement-lime plasters
Stabilized min. 7 days*. Prime with ATLAS UNI-GRUNT.
Gypsum plasters
Prime with ATLAS UNI-GRUNT. If the gypsum plaster is applied in a wet room it should be protected thoroughly against moisture. If damp has the form of short term action or average water splash, then the plaster should be coated with a preparation improving resistance against damp penetration, e.g. ATLAS GRUNTO-PLAST. In environment more subject to damp it is necessary to apply a watertight coating, e.g. ATLAS WODER E.
Stabilized min. 21 days; optimum moisture content < 4% by weight. Remove remains of formwork oils and other substances which would impair adhesion obligatorily. Holes, cracks and other gaps should be filled with ATLAS BETONER system mortars.
*The time shown in the table is recommended for the application in the temperature 20°C and humidity 50% (approx.).

Adhesive preparation
Pour the adhesive from the bag into a container with the suitable amount of water (see Technical Data for ratio) and mix, using a low speed mixer with a drill for mortars, until homogenous. The dispersed adhesive should be left to rest for 5 minutes and then remixed. So prepared adhesive should be used up within approx. 4 hours.
Adhesive application
The adhesive should be applied onto the surface with a steel trowel and then distributed evenly and shaped (possibly in one direction) using a notched trowel. It is advisable to spread a thin adhesive coat first and then apply the coat of desired thickness and shape it with a notched trowel. It is recommended to lead a notched trowel in one direction. On walls, it’s recommended to shape the adhesive in vertical direction.
Installing the tiles
After the application, the adhesive retains its properties for approx. 30 minutes (in temperature approx. 23 °C and 55 % humidity). Within this time, the tile must be placed and pressed well (the contact surface between the adhesive and the tile should be uniform and as large as possible – min. 2/3 of tile surface). Remove the excess of the adhesive pressed into the joints immediately. In case of floor tiles or tiling outdoors it is advisable to keep the full bonding surface (use the mixed method consisting in application of the adhesive on the substrate and the back of a tile, if needed). Keep the joint width appropriate for the tile size and operation conditions (check data in the sheets of ATLAS grouts).
Tile adjustment
The position of a tile can be adjusted with delicate moves along the bonding plane. It can be done within approximately 10 minutes since the tile is pressed (in temperature approx. 23 °C and 55 % humidity).
Grouting and cladding use
Foot traffic and grouting with ATLAS GROUT, ATLAS ARTIS GROUT, ATLAS DECORATIVE GROUT or ATLAS EPOXY GROUT can start after approx. 24 hours since the tiles fixing. The mortar reaches the operational strength after 3 days (check the Technical Data). Expansion joints, joints along the wall corners, at sanitary equipment, etc. should be filled with sanitary silicone ATLAS SILTON S or ATLAS ARTIS.

• The tiles must not be soaked before fixing. When determining the adhesive thickness under the cladding, one should consider the geometric deviation of tiles shape, e.g. plane warpage. Tiles subject to discoulouration in contact with grey cement should be applied with the use of adhesives based on white cement binder.
• When fixing the tiles on weak substrates which bearing capacity is difficult to establish (e.g. dusty, difficult to clean), it is recommended to perform an adhesion test by fixing a tile and checking the bond after 48 hours.
• Open time – from the moment of application of the adhesive to the moment of placing the tiles upon it – is limited. In order to check if it is still possible to fix tiles, performing a test is recommended. It consists in pressing your fingers against the adhesive. If the adhesive remains on the fingers, you may fix the tiles. If the fingers are clean, the old layer of the adhesive has to be removed and a new one applied.
• The tools must be cleaned with clean water directly after use. Difficult to remove residues of the set adhesive can be removed with the ATLAS SZOP agent.
• Contains cement. May cause respiratory irritation. Causes skin irritation. Causes serious eye damage. May cause an allergic skin reaction. Keep out of reach of children. Avoid breathing dust. Wear protective gloves/protective clothing/eye protection/face protection. IF ON SKIN (or hair): Remove/Take off immediately all contaminated clothing. Rinse skin with water/shower. If skin irritation or a rash occurs: Get medical advice/attention. IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do – continue rinsing. Follow the instructions of the Safety Data Sheet.
• The adhesive must be transported and stored in tightly sealed bags, in dry conditions (most preferably on pallets). Protect against humidity. Shelf life in conditions as specified is 12 months from the production date shown on the packaging. Content of soluble chromium (VI) in ready-to-use mix - ≤ 0.0002%.
