If exterior wall is not smooth loose surfaces are removed and leveled. HEKIMPOR standard plates is mounted on the exterior surface of the wall with adhesive plaster and fixed with 6 plastic insulation pegs per m². It should be checked that the joints fit tightly during the assembly of the plates. Then plaster mesh is applied with the same plaster and premixed plaster or exterior paint is applied after 2 layer of plaster is applied on the mesh.
HEKIMPOR standard plates are made ready for finish plaster by mounting them on the interior surface of the wall just like they were mounted on the exterior surface and tape mesh is applied on joints where joints are connected. There is no need to apply tape mesh if plasterboard (gypsum board) or any interior covering material will be used instead of plaster.
Surface is leveled, water-proofing is ensured by applying bitumen and HEKIMPOR plates are adhered on the exterior walls below ground level. The process is completed after pressure wall is built and regular earth filling is performed. Utmost attention should be paid to joints to make sure they fit tightly. There is no need to adhere the plates if putting up pressure wall and earth filling process is performed at the same time.
After reinforced concrete floor;
After leveling concrete is applied on the reinforced concrete floor bituminous covering material should be furnished for water proofing bitumen and then HEKIMPOR plates should be placed with their flat surfaces at the bottom and joints fitting tightly. Geotextile fabric should be laid on HEKIMPOR plates and lastly ceramic tiles which will be used in the flooring are tiled with the aid of mortar.
Application surface should be smooth; if lateral and vertical wall irregularity is over 1 cm on unplastered surfaces, firstly it should be leveled with plaster. Otherwise irregularities on the surface will mess the flatness of plates. Dirt, grease or paint wastes should be cleaned off and surface should be moistened by watering before application.
Basement profile, one of the main bearers of the system, should be 4-8 mm wider than the insulation panel. Profile should be made of aluminum with a thickness of around 1-3 mm. Profiles should be assembled sensitively at the basement level and profile assembly should be repeated in every two or three floors in high-rise buildings.
HEKIMPOR, used as an insulation panel, is applied to the back surface of the panel with adhesion, chiseling or framing method in such a way to cover at least 40% of it. Plates should be adhered on the application surface as tongue and groove.
The pegs should be made of plastic. Peg Length: ‘Panel Thickness + Adhesive Thickness + min. 3 cm Surface Connection.
Aluminum corner profiles should be fixed near windows and doors where panels form the outer corner (24 hours before plaster is applied on HEKIMPOR insulation panel) by using insulation panel plaster. Thus, this type of corners and places which will remain thin in the insulation boarding system will be reinforced and resistance to impacts will be maintained. Products in the system should be applied in temperatures over +5 °C-
Surface of HEKIMPOR should be wiped with wet sponge and surface moisture and cleanliness should be provided before applying plaster. Plaster mixture is applied on HEKIMPOR in 2-3 mm thickness.
Glass fiber mesh for plastering (pore opening 4 mm, weight 160 gr / m2, resistant to alkaline) is extended over the surface, while applied insulation panel plaster is still wet, in a way that joints overlap 5-10 cm to increase mechanical strength. 2-3 mm thick insulation panel plaster is applied again, trowelled and it is ensured that mesh is embedded in the plaster.
Applied plaster should be watered within the first 12-24 hours and in case of very hot weather, it should be watered once every two days for two times more to ensure proper hardening of plaster. One should wait for three days minimum for cladding following plaster application. The plaster applied on the surface for the purpose of protecting the insulation boarding system will be saturated in water and then left to drain.
Then 2-3 mm decorative coating is applied on the surface with machine, roller or plastic trowel. Applied covering should be watered within the first 12-24 hours and in case of very hot weather it should be watered once every two days for two times more to ensure proper hardening of plaster.
One should wait for three days minimum for lining following plaster application. Then exterior lining is applied in a thin layer. Waiting time is 2-4 hours after application.
Exterior paint is applied on the surface in two layers after lining. Waiting time 12 hours between application of each layer. Thus, the thermal insulation system is completed.
Note: Products inclusive of the system should be applied in temperatures over +5 °C.
