CERESIT CT 82 | Adhesive mortar & Base coat

Ceresit CT 82 is a dual-purpose cementitious mortar for external thermal insulation composite systems (ETICS): it is used both for fixing expanded polystyrene (EPS) and extruded polystyrene (XPS) boards, and for creating the reinforced base layer with glass fibre mesh. Fibre-reinforced, with high adhesive strength, good water vapour permeability and impact resistance — it is a key structural component of Ceresit Ceretherm systems.

ARGYNET LAB framing: One bag for two jobs. CT 82 bonds the thermal insulation boards and, once set, forms the reinforced base layer on top of them — simplifying site logistics and ensuring compatibility within the certified Ceretherm system (ETA Popular & Impactum). It is suitable for graphite EPS and for mechanical application. At ARGYNET, we support the composition of the complete external wall insulation system (primer → board → adhesive/base coat → mesh → finishing primer → decorative render).
