THE INSTALLATION
Substrate
Before installing the system, the substrate that could be made of bricks, cement, mortar, cement board etc, must be thoroughly examined and be free of any rotten parts. The flatness of the substrate must be checked also, so that we can achieve the appropriate alignment of the system during its installation which is very important.
Insulation Pasting
We initially place the startup guide of the system, if needed, so that it can indicate a steady horizontal base for the coating of the insulating plates that will follow. We then mix the coating material SYSTEM TECHNICA CLIMA ST100 with 6 liters of water either manually with a mixer tool or an electric mixer, so that a uniform mixture is formed. We then place the mixture on the insulating sheet perimetrically and we also place spot of the mixture in the center of the plate so that we can cover at least 40% of the surface or we brush evenly the whole surface of the plate with a notched trowel if the flatness of the substrate allows us to do so. In order to achieve the right result with the pasting it is necessary that we do not exceed 2cm of the material (adhesive). If needed, in such case, we change the thickness of the insulating material. The plates are always placed crossways with the grouts hermetically closed and their flatness as well as the workability of the pasting material must be checked. We are very careful with the meeting points of the system with windows, lintels, covers, expansion grouts to avoid thermal bridging, as well as with the correct proofing. When the required time for the hardening of the pasting material has passed we can scrub the insulating plates, if needed, that we can achieve the appropriate substrate for the coating of the basic mortar mix that will follow.
Mechanical Anchoring
When the pasting material has dried by using the appropriate in length special connectors we mechanically anchor all the coating of the insulating material with 6 pieces per square meter. We place the connectors always where there is pasting material at the back side of the insulating material to avoid undesirable bending of the insulating plates. Coating basic mortar and encapsulating reinforcement fiberglass
We mix SYSTEM TECHNICA CLIMA ST100 with 6 liters of water so that a uniform mixture is formed. Initially we place the relevant special accessories, such as corner beads, water drippers, expansion grouts, if any, proofing profiles of aluminums, as well as diagonal pieces of fiberglass to the corners of the aluminums to avoid cracking. We then place evenly the material with a notched trowel throughout the whole surface of the insulating plates and we encapsulate the reinforcement grid 2 on the damp substrate. Next, we flatten the surface with a straight spatula so that the reinforcement grid is fully covered. It is important that the reinforcement grid is inter-covered by 10 cm. We recommend that the thickness of the basic mortar is 4-5 mm so that a strong reinforced substrate is created for the final mortar that will follow either in the form of a dry mortar or a paste.
Final coatings
In the form of dry mortar
When the basic coating is dried well and is ready to be applied with the final coating SYSTEM TECHNICA CLIMA ST200, we mix ST200 with 6 liters of water so that a uniform mixture is formed. We check that the substrate is clean and apply ST200 on the whole surface evenly either by hand or with the relevant mechanical equipment. We flatten the surface and depending on the weather conditions, when the mixture has dried we polish it by using a damp pan float in order to achieve the ideal result. It is recommended that the thickness of the final coating is 2-3 mm. After the surface is dried well and primed with the appropriate prime it is then ready for the final coloring.
In the form of paste
When the basic coating is dried well and primed with the appropriate prime it is then ready to be coated with the final coating in the form of paste. The final coatings in the form of paste are ready for use, they only need a simple stirring and also they allow us to choose from a variety of different colors through the available reference color. We check that the surface is clean and apply the material throughout the whole surface. It is essential that the surfaces are completed from end to end to avoid undesirable bi-colorings. After the material is dried, depending on the weather conditions, it can be scrubbed or forged for the final desirable result.
High proofing zone
It is essential that a high proofing zone is created wherever the system is in touch with the ground or points of high humidity. In such case and for 30-40 cm over the final level of the system we proof the substrate with the coating cement based mortar WATER PROOFER by SYSTEM TECHNICA and place insulating plates of high density e.g. EPS200 or XPS, which have really low absorbance and increased mechanical shock capacity. We always make sure that we have good water runoff at the points that are in touch with the proofing zone around the building.
