Adhesive for foamed polystyrene and XPS and for execution of the reinforced layer. 2 in 1 - it is designed for fixing thermal insulation panels and for execution of the reinforced layer in thermal insulation of buildings technology. Element of thermal insulation systems – it is a part of composite thermal insulation systems, awarded with European (ETA) technological approvals. Enables fixing various expanded and extruded polystyrene boards - including expanded polystyrene boards with addition of graphite and elasticized.

  • high adhesiveness
  • good water vapor permeability
  • reinforced with microfibres
  • resistant to cracks and scratches
  • for bare and rendered walls

Types of construction substrates:

  •  all classes of concrete, 
  • aerated concrete, 
  • cement
  • plaster, 
  • cement-lime plaster, 
  • sandstone and bare walls made of brick,
  •  blocks,
  • hollow brick and other similar ceramic or silicate materials.

Properties:

  • Elastic – compensates strain resulting from the influence of temperature and usage upon other layers of the system.
  • Increased resistance to cracking – it is reinforced with cellulose fibres.
  • Highly adherent – strongly adheres to difficult substrates, e.g. substrates covered with strongly adhering paint coats. 
  • Vapor permeable – does not limit the flow of water vapor through the insulated partition.

Substrate preparation

The substrate should be unfrozen, 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. Before work commencement, clean the substrate and, if excessively absorptive, prime it with ATLAS UNI-GRUNT. Priming is also necessary in case of such substrates as weaker cement or cement-lime plasters and walls made of cellular concrete or slag concrete hollow bricks. Fill in larger irregularities and cavities with ATLAS LEVELLING MORTAR or ATLAS PLASTERING MIX.

Preparation of panels for the reinforced layer
Before the execution of the reinforced layer, the surface of foamed polystyrene boards should be hoarfrost free, even, clean, stable and de-dusted, if boards were ground after fixing.

Adhesive preparation

Pour the mortar from the bag into a container with suitable amount of water and mix until homogenous with a drill with a mixer. Leave the mortar to rest for 5 minutes and then remix. The ready to use adhesive must be used up within ca. 4 hours.

Fixing the panels

Apply ATLAS HOTER U adhesive on the wall contacting side of the panel using the “strippoint” method. It consists in the application of continuous circumferential block (at least 3 cm wide) at the edge of the board and 6÷8 patches of 8÷12 cm in diameter evenly distributed on the whole surface. In total, apply as much adhesive as sufficient to cover at least 40% of the surface of the panel (after pressing down to the substrate, at least 60%) and to ensure appropriate binding of the panel with the wall. Immediately after the application of the mortar on the board, fix the board to the substrate and strike it to place it in the required position, so that the mortar thickness under the panel does not exceed 1 cm. In case of even and smooth substrates, the mortar can be evenly
distributed with a notched float on the whole surface of the panel to ensure 2÷5 mm of adhesive layer after fixing.

Execution of the reinforced layer

The execution of the reinforced layer can start after the adhesive used for fixing foamed polystyrene panel has set appropriately and after the application of additional mechanical fixing, if necessary (after 3 days on average). Distribute the adhesive upon the surface of the fixed insulation with a notched float and sink the reinforcement glass fiber mesh into it. It is recommended to sink the mesh in in vertical strips and float the surface so that the mesh is not visible on the one hand and does not directly contact the foamed polystyrene panels on the other.

Consumption:

Individual consumption of the adhesive depends on the properties of the substrate (its evenness among others) and on the accepted technology of fixing the panels.

  • Fixing boards: from 4.0 to 5.0 kg/m2
  • Reinforced layer installation: from 3.0 to 3.5 kg/m2.

Important additional information:

Mortar parameters can be fully utilized if it is used with other elements of the system and in accordance with its installation method.
  •  During works, scaffolds must be shielded. Carrying out works in snowfall, rainfall and in strong wind is forbidden.

  •  In case of fixing foamed polystyrene panels on weak substrates whose bearing capacity is hard to determine (e.g. unstable, dusty, difficult to clean), it is recommended to make an adhesion test. It consists in fixing of 8÷10 cubes of expanded polystyrene 10x10 cm each, in various places of the façade and checking the bonding after 3 days. Substrate resistance can be deemed sufficient if the foamed polystyrene cube tears during the attempt of removing it. If the cube is removed with the mortar and substrate layer, it means that the substrate is not structurally sound enough. Further procedure for such case, e.g. the determination of the method of the weak layer removal should be described in the relevant technical design of the insulation.

  •  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 SHOP agent. 

  •  Irritant – includes cement. Irritates respiratory system and skin. Risk of serious damage to the eyes. Can trigger allergic reaction on contact with skin. Due to its form – dust, the mixture can mechanically irritate eyes and respiratory system. Keep out of the reach of children. Do not inhale the dust. Rinse contaminated eyes with large amounts of water and seek doctor’s assistance. Wear appropriate protective clothing, protective gloves and goggles or face protection. In case of ingestion immediately seek doctor’s advice – show the packaging or label. Proceed according to the Specification Sheet.

  •  The adhesive must be transported and stored in tightly sealed bags, in dry conditions (most preferably on pallets). Protect against humidity. The shelf life period in conditions conforming with those specified above is 12 months from the production date shown on the packaging. Content of soluble chromium (VI) in ready-to-use mix - ≤ 0.0002%.
