Adhesives and Basecoats - AVAL


2 in 1 – designed for fixing thermal insulation boards and for the reinforced layer (base coat) installation in the external thermal insulation of buildings.
Element of the thermal insulation systems – an element of composite thermal insulation systems, granted the European Technical Approval (ETA).
Enables fixing various expanded polystyrene boards – including graphite – enhanced, with addition of graphite and elasticized expanded polystyrene boards. The main characteristics • very high adhesiveness
• reinforced with microfibres
• resistant to cracks and scratches
• application in low temperatures (even from 0°C)
• also for graphite - enhanced EPS
• BBA Certificate
• NSAI Certificate
The main parameters • base coat bed thickness: 2 - 5 mm
• adhesion to expanded polystyrene: min. 0.1 MPa
• adhesion to concrete: min. 0.6 MPa
• consumption: boards application: from 4.0 to 5.0 kg/m²
• consumption: base coat application: from 3.0 to 3.5 kg/m²

Availability: In stock

Increased resistance to cracking – it is reinforced with cellulose fibres.
High flexibility – perfectly compensates thermal and mechanical stress exerted on other layers of the system.
High adhesion – strongly bonds to problematic substrates, such as surfaces with well-bonded paint coats.
Water vapour permeability – does not restrict water vapour transmission through the insulated wall.

AVAL KT 85 is manufactured as a dry mix of cement binder, aggregates and modifying agents, reinforced with cellulose fibres.
