The first step of jacketing is to place EPS or CARBON REINFORCED EPS boards on the exterior walls using adhesive mixture. The cementing process starts by accumulating on board or spreading on the board using a pointed trowel. The board covered with adhesive shall be placed on the exterior walls.
The boards cemented at this stage should be in full contact with each other. Any gap between the boards shall create heat build-up and that build-up might have undesired consequences. The board cementing process shall be from bottom to top on a level surface and floating rule, rope shall be used for the process.
The boards should be lined up in tusk tenon structure.
Boards should be secured on the walls using dowelled joints after they are cemented and dried. There are different dowelled joint options for exposed concrete, brick, gas concrete and wood surfaces. It is a necessity to use dowels suitable to the structure of each ground.
Dowelled joints shall be nailed into holes drilled. The dowelled joints should be placed on joining points and center of boards on façade. Minimum 6 dowelled joints should be used for 1 m2. In case of high-rise buildings, minimum 8 dowelled joints should be used after the 10th floor because of increased wind load and even dowelled joints with steel nails might be used. The cap of dowelled joints nailed should be embedded in the board and they should not stick out.
Corner profiles should be placed from bottom to top on each corner of the building (window corners, balcony corners etc.) by using adhesive mortar, floating rule and scale for preventing cracks and creating a smooth center.
The walls should be plastered with special plaster after placing dowelled joints and corner profiles. The plaster shall be spread on the wall using a steel trowel and mesh shall be placed on it. While placing the mesh, make sure that mesh bands overlap with each other minimum 10 cm. After embedding mesh into plaster, a second coat of plaster should be applied on the wall as a grading coat.
There should be no uneven surfaces, juncture traces and uncovered mesh after the second coat of plasterwork.
Primer specifically produced for decorative plasterwork applications should be spread onto the wall when the mesh plasterwork is dry. This paint-like primer shall be applied on the wall using a roller brush.
Decorative plaster creates hard, rough and durable wall thanks to mineral particles inside the plaster. The plaster shall be spread using a clover trowel (plastic trowel). The pattern manually created by the mason while applying the decorative plaster is important.
Paint base shall be applied for exterior wall painting.
Two coats of paint shall be applied after priming and you should wait for 12 hours between coats.
The exterior work will be then complete.
