Adhesive and reinforcement mortars

Granol'therm G is used as a bonding adhesive for insulating boards in the Granol'therm EWI system. It is also used as a reinforcing and levelling coat with a fibre mesh such as Granol'therm AGF embedded.

Factory-made dry mineral mortar according to DIN 18557, corresponds propertywise to mortar group P II, weatherproof, according to DIN 18550

 

Granol’therm G can be applied with all render machines on condition that you follow the manufacturer's instructions.

In applied manually, the dry mortar is intesively mixed with approx. 6 -7 liter clean water. Drying time: approx. 2-3 days depending on substrate and weather conditions. Do not apply at temperatures below +5°C or, on frozen substrates or above +30°C.
Further instructions can be found in the technical datasheet Granol’therm G.

Bonding:
For bonding rigid foam insulating panels on even substrates, the mortar is applied with a notched trowel 10/12 to obtain a ribbed mortarbed on the entire surface of the dry panel. For uneven substrates the mortar is applied along the sides of the panel’s surface forming a frame, then two stripes of mortar are applied in the middle of the surface dividing the frame into three parts. Beware to precisely apply the mortar along the sides of the panel’s surface.

Reinforcement and embedding:
For the embedding of the reinforcement mesh, Granol’therm G is applied uniformly over the insulation panels with a flat spatula. The mesh is applied downwards in the mortar and is then levelled out covering the whole mesh.
The total thickness of the mortar and the mesh together should be inbetween 3 and 5 mm. The mesh should be on the upper side of the coat i.e. if we were to split the mortarcoat into two halfs the mesh should be just in the outside half of the coat. The meshstrips should overlap eachother by at least 10 cm. After a dryingprocess of 2 to 3 days (or longer according to the weatherconditions) the primer and top coat render can be applied.

Fresh render must be protected against torrential rain and against too fast drying. Especially by direct sunlight or wind exposure the facade should be correctly protected i.e. by hanging a protectionnet. Do not apply when the substrate or the environmental temperatures are below 5° C.
Tools and machines should be cleaned immediately after application with water. Other parts of the building such as windows, doors or tresholds should correctly be protected.
