Product description
ATLAS STOPTER K-20 is produced as a dry mixture of the highest quality cement binder, aggregates and specially selected modifying agents.

It is a component of external wall insulation systems. It is used for:
- for bonding thermal insulation boards made of EPS (white and graphite) polystyrene and providing a reinforced layer over them,
- for the permanent fixing of thermal insulation boards up to 25 cm thick.

ATLAS STOPTER K-20 is recommended as a reinforced layer under plasters on large surfaces designed in dark, intensive colours - it extends the possibilities of free shaping of façade colours, e.g. it allows lowering the required HBW coefficient even up to 10 %.

It is recommended for insulation work in passive and energy-efficient construction passive and energy-efficient building systems - helps achieve the building envelope airtightness required in passive construction.

It can be used to provide insulation for newly constructed buildings and those undergoing thermal modernisation.

Properties
    It has very high adhesion - due to its increased polymer dispersion content, it exhibits high adhesion to mineral substrates and to EPS and XPS boards. This parameter is also favourably influenced by the varied, tight bulk density of the aggregate mixture. The mortar adheres strongly even to difficult substrates, e.g. paint-coated surfaces with good adhesion to the substrate.

    Allows work to be carried out in a wide range of temperatures - not less than 0 °C during the work and not less than -5 °C after 8 hours after completion.

    It has increased resistance to cracking - thanks to the structural fibre reinforcement, the mortar has increased resistance to:
    - formation of micro-scratches in the initial setting stage,
    - the formation of cracks during the life of the system.

    It is vapour-permeable.
