Mapetherm AR1

Mapetherm AR1 is a one-component cementitious mortar, in white or grey color, composed of cement, selected aggregates, synthetic resins, and special additives. It is suitable for all types of thermal insulation materials and is used for bonding and levelling insulation boards in external thermal insulation systems (Mapetherm Systems).

▪ External thermal insulation systems (ETICS): reinforced bonding and levelling of insulation boards (EPS, XPS, PIR, phenolic foam, mineral wool, wood fiber, cork, aerogel, etc.) on walls or ceilings, applied directly onto renders, masonry, concrete, or wooden substrates (such as OSB-3 and CLT).
▪ Levelling coats, including reinforced coats, for both interior and exterior applications.
▪ Reinforced levelling coats on boards (fiber-cement type) used as cladding for ventilated façades in exterior applications

Low viscosity, therefore easy spreading.
High thixotropy: Mapetherm AR1 GG can be applied on vertical surfaces without flowing and without the risk of insulation boards slipping, including large-size boards.
Excellent adhesion to all insulation boards and all conventional building substrates: skim coats, traditional plasters, existing paints, and decorative coatings with good adhesion.
Strength development without significant shrinkage.
Excellent finish due to the fine grain size.

▪ Perimeter and spot bonding of thermal insulation boards: approximately 3.0–4.0 kg/m²
▪ Bonding of thermal insulation boards with full-surface application of adhesive to the back of the insulation board: approximately 4.0–6.0 kg/m²
▪ Reinforced leveling mortar: (recommended thickness 4 mm in 2 layers): approximately 1.3–1.5 kg/m² per mm of layer thickness
