GRAWIS U - 2 in 1 – designed for fixing thermal insulation boards and for the reinforced layer (base coat) installation in the external thermal insulation of buildings. Enables fixing expanded polystyrene boards – including boards with the addition of graphite and elasticized and also reinforced layer in the technology of building insulation.
The main characteristics
- for EPS application and for mesh embedding
- recommended height up to 12 m
- high adhesion to the substrate
Properties
Optimally balanced formula - provides adequate adhesion for polystyrene and allows easy implementation reinforcing layer.
High adhesion - adheres strongly to mineral surfaces and for polystyrene, allows you to glue insulation boards up to 25 cm thick.
High viscosity - the adhesive does not slide out of the trowel and the board surface.
High plasticity - when applied to a substrate and perform layer reinforcing the adhesive does not rolled, does not break up, not stretches, etc.
Longer duration of readiness to work - reducing the need for additional mixing unused glue.
Longer duration of correction - allows correct positioning boards.
Flexible – compensates thermal and mechanical stress exerted on other layers of the system.
Water vapour permeability – does not restrict water vapour transmission through the insulated wall.
