Product description
In ETICS systems:
- for bonding mineral wool thermal insulation boards up to 30 cm thick,
- for bonding thermal insulation boards made of EPS polystyrene (white and graphite) up to 50 cm thick,
- for applying a reinforced layer on them.

It is recommended for insulation work in passive and energy-efficient construction

Properties
    ATLAS GRAWIS DUO is produced in the form of a dry mix of the highest quality cement binder, aggregates, polymer dispersions and modifying agents.

    Flexible – has 3D reinforcement – the fibres in the product provide additional dispersed reinforcement, thanks to which the mortar is protected against microcracks and has better mechanical resistance.

    *Maximum adhesion after just 24 hours (measured at +20°C):
    - adhesion to polystyrene foam (EPS TR80) after 24 hours is a minimum of 0.08 MPa,
    - adhesion to mineral wool is at least 0.015 MPa (MW TR 15)
    - adhesion to concrete is a minimum of 0.25 MPa.

    Rapid strength gain – dowelling or priming for rendering can be started after:
    - 24 hours, at a temperature of approx. +20 °C and humidity up to 80% (lower temperatures prolong and higher temperatures shorten the drying time). - 48 hours, if the temperature during this time is between +3 °C to +10 °C and humidity up to 80%.

    High durability during use – thanks to the high content of redispersible polymer powders, microfibres and special additives and modifiers, the durability of the adhesive and its resistance to atmospheric and thermal factors have been increased.

    Possibility of using various thermal insulation materials with different hardness and wettability – during application, the adhesive achieves excellent adhesion, does not roll, tear or pull.

    It allows two thermal insulation materials to be joined together to meet fire safety requirements.

    High vapour permeability – does not restrict the flow of water vapour through the insulated
    partition, which is particularly important when using mineral wool.
