Rules for the installation of the reinforced layer: Reinforcement is covering the surface with putty and pressing the fiberglass mesh into the newly applied putty. The adhesion force of the putty to the insulating plate after drying must be at least 0.03 N/mm², tested by the wet method. The color of the net must not be visible after finishing the reinforcement work, the texture of the net may shine through. The net must not be loose, damaged, creased or folded. When reinforcing, it is necessary to ensure that the thickness of the top layer is not greater than in other places. If this requirement is not met, then marks of the reinforcing mesh may appear from under the finishing layer. It is recommended to check the straightness of reinforced areas with a measuring ruler. If the reinforcement areas have become uneven, the entire surface must be covered with reinforcing putty again. Protruding parts of the reinforcing mesh (for example, at the plinth busbar) must be cut off immediately. In the warm season, a layer of putty about 1 mm thick dries in a day, that is, after 3-4 days the surface is ready for other works. The reinforced surface should be uniformly light gray in color. The reinforcing putty is mixed to form a uniform mass and kept for about 10 minutes before use. When laying the fiberglass mesh, it is pressed into the putty so that the putty penetrates through the eyelets of the mesh. The putty that has penetrated through the eyelets of the net is leveled. This makes the putty surface smooth and the reinforcing alkali-resistant fiberglass mesh is inside (it is recommended to be in the upper third of the layer). It is not allowed to hang the fiberglass net on the polystyrene foam (polystyrene) surface and try to push the putty through the net holes from above. The network is laid from top to bottom across the entire area of the facade. About 10 cm should be left at the places where the net passes. More information at www.etnaeps.lt
