STOPTER K-50 white general use adhesive for external wall insulation
Together with mineral plaster and wool insulation, it allows achieving fire class A2
Most important features:
no priming mass required
for mineral wool and polystyrene (also for graphite polystyrene)
for boards and base coat installation
reinforced with microfibers
very good application parameters
can be applied manually or mechanically.
Product description:
ATLAS STOPTER K-50 is manufactured as a dry mix of high quality cement binder, aggregates and modifiers, reinforced with fiberglass.
ATLAS 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:
High resistance to micro-cracks – thanks to a special selection of fine fillers and additional structural reinforcement with a special 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 redispersible polymers, microfibers, special additives and modifiers.
White cement base – the use of white cement reduces the formation of discoloration or gaps on the plaster (especially in white and pastel colors) and allows you to avoid additional painting.
Very high adhesion – the high content of polymer dispersions ensures higher adhesion to to problematic substrates.
Vapor permeable.
Limited absorptiveness – together with thin-coat renders perfectly protects thermal insulation against water action.
The adhesive can be applied manually or mechanically.
