One-component cementitious mortar for bonding and levelling insulation panels and for external thermal insulation systems.
Mapetherm AR1 is used for bonding and smoothing floors and ceilings, in interiors and exteriors, insulation panels (made of extruded and foam polystyrene, foam polyurethane, rock wool, cork, etc.) directly on the render, concrete and concrete blocks.
Mixed with water, Mapetherm AR1 becomes an easily workable thixotropic mortar that can be applied on vertical surfaces without sagging and without letting large size insulating panels slip.
To bond insulating panels, apply Mapetherm AR1 directly on the back side of the panels with a notched trowel. Either cover the panel completely with the product or spot bond. To smooth insulating panels, wait at least 24 hours after their installation then apply a uniform coat of Mapetherm AR1. Insert Mapetherm Net and squeeze it with a flat trowel into the fresh mixture.

- 4.0-6.0 kg/m2 according to bonding technique;
- 1.3-1.5 kg/m2 per mm of thickness as smoothing compound (recommended: ca. 4 mm in two coats).

25 kg bags.
