DescriptionATLAS STOPTER K-50 is an element of the thermal insulation system and is used for: fixing of EPS thermal insulation boards (white and graphite) and making a reinforced layer on; fixing of mineral wool thermal insulation boards (façade and lamella) and making a reinforced layer on.,
ATLAS STOPTER K-50 is recommended as a reinforced layer for render coats on large surfaces in dark, intense colours – it extends the range of available façade colours, e.g. the required HBW coefficient can be reduced to as much as 10 %.
Recommended for works where there is a need to combine two different thermal insulation materials: mineral wool and EPS boards – especially in the case of facades with fire protection.
Recommended for insulation of standard, passive and energy efficient buildings – helps to reach the partition tightness required in passive housing, fixes insulation boards even 25 cm thick..
Main properties:
- ATLAS STOPTER K-50 is manufactured as a dry mix of high quality cement binder, aggregates and modifiers, reinforced with fiberglass.
- High resistance to microcracks – thanks to a special selection of fine fillers and additional structural reinforcement with a unique combination of microfibres.
- High durability – the durability of the reinforced layer and resistance to weather conditions have been increased with the use of a combination of polymers, microfibers, special additives and modifiers.
- White cement base – the use of white cement reduces the chance of discolouration of the top coat (especially in white and pastel colours).
- Very high adhesion – the high content of polymer dispersions ensures higher adhesion to problematic substrates. Na kształtowanie tego parametru korzystnie wpływa również zróżnicowany, szczelny stos nasypowy mieszanki kruszyw. Zaprawa mocno przylega do trudnych podłoży, np. do powierzchni pokrytych silne przylegającymi powłokami farb.
- It’s breathable (vapor permeable)
- No priming mass is required – the unique structure of the bonded adhesive creates a layer to which the thin coat renders adhere strongly, and the white cement reduces the possibility of discolouration. This method is recommended for mineral, acrylic and hybrid top coats only.
- Limited absorptiveness – together with thin-coat renders perfectly protects thermal insulation against water.
Consumption
– Bonding polystyrene boards: from 4.0 to 5.0 kg/m².
– Creating the reinforced layer on polystyrene boards: from 3.0 to 3.5 kg/m².
– Bonding mineral wool boards: from 4.5 to 5.5 kg/m².
– Creating the reinforced layer on mineral wool boards: from 5.5 to 6.5 kg/m²..
The exact consumption will vary, please estimate the consumption based on a sample.
