Polymer modified render for internal/external wall insulation systems.
Mapetherm AR1 is used for bonding and smoothing floors and ceilings in interiors and exteriors insulation boards (made of extruded/expanded polystyrene, 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 dripping and without letting large sized 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 the Mapei Fibreglass Mesh and squeeze it with a flat trowel into the fresh mixture.
