Préparation de Couches de Mortier en Plâtre et Application de Filet en Fibres de Verre

After adhering Teknosistem thermal insulation boards and applying wall plugs, two layers of surface plaster is applied. Teknosistem Plaster Mortar prepared is applied homogenously on the surface with a steel trowel (Figure 1). Application thickness of the surface plaster should be maximum 2 mm for each layer.

The glass-fiber mesh should be applied on the first layer of surface plaster when it is still wet, by pressing from top to bottom and stretching widely, without folding, and placing at an equal distance from the insulation board to the whole surface. In joints, glass-fiber meshes should always be overlapped for 10 cm (Figure 2).

The second layer of plaster mortar is applied at least 3-4 hours afterwards, before the first layer of plaster mortar is dried. In order to prevent the glass-fiber mesh from being dislocated or immersing in the first layer of plaster mortar during application, application of the second layer of the plaster mortar is completed after waiting for slight dehydration of the first layer depending on weather conditions (Figure 3). Therefore, the surface is ready for exterior wall coating.
