  Application Procedure

  • Application Surfaces
    Indoors and Outdoors Walls;
    Cement based plaster
    Concrete
    Indoors and Outdoors Floors;
    Cement based trowel coating
    Concrete

    Surface Preparation :
    The application surface should be dry, clean, sound and dust free, and should have been cleansed of oil, dirt or any materials that may prevent adhesion, and any such materials as mortar and cement residues should be scraped from the application surface.
    The humidity content of the surface should be 5 % at maximum.
    The fresh concrete surface should be let dry for minimum 28 days before application.
    The surface, on which MegaIzo PU 7 is to be applied, should strictly not be washed with water.
    For lasting waterproofing, the cracks and joints on the surface should be thoroughly and carefully sealed prior to application.
    The surface defects, which are deeper than 1 cm, should be repaired with MegaTamir Epo, MegaTamir EpoGrout or MegaTamir K 6-8 hours in advance. In the cases, where structural repair mortar should be used; MegaTamir K Yapısal should be preferred.
    Following the surface cleaning, MegaFilm Izo PU, in the case of absorbent surfaces, or MegaFilm Izo Epo, in the case of non-absorbent surfaces, should be applied in single coat in order to enhance adhesion strength and stabilize the surface absorption. Such surfaces coated with MegaFilm Izo PU primer should be let dry for 2 to 3 hours while those coated with MegaFilm Izo Epo should be let dry for 8 to 12 hours.

    Application Methods :
    • MegaIzo PU 7, which should have been thoroughly stirred prior to the application, which should have been applied with primer and should be maintaining its adhesive nature to a certain extent, and be spread to cover the entire surface with a roller or brush.
    • MegaIzo PU 7 should be applied in double coat on the surface.
    • The secondary coat should be applied 12 hours (maximum 36 hours) after the application of the primary coat.
    • Edge and corner joints should be beveled with MegaIzo PU Mastic in order for the maintenance of waterproofing.
    • In the cases, where beveling is not performed; MegaIzo Bant should be applied to such inadequately waterproof spots as edge and corner joint spots in order to ensure the maintenance of insulation.
    • Depending on the nature of the application surface; the secondary coat should be applied after the placement of waterproofing net on the primary coat. In the cases, where net reinforcement is necessary; the net shall be laid on the primary coat before it dries.

    Application Recommendations :
    • The amount consumed and the thickness of application should be increased in the cases, where ceramic tile coating is applied on the insulation, and the surface, to which Megaİzo PU 7 is applied, should be sanded before it dries completely.
    • Due care must be taken to ensure that the insulation material is not damaged by mechanical impacts in the cases of coating over the insulation.
    • The product should not be applied against negative water pressure.
    • The product should be used before the expiration of its pot life. Any product, the pot life of which has expired, should not be used during the application.
    • MegaIzo PU 7 is a ready to use product. Any foreign material should not be added into the product during the application.
    • The product should not be applied on unsound surfaces. The soundness and the load-bearing capacity of old surfaces should be checked prior to adhesion.
    • The surface should be preserved from air currents and water contact during and after the application.
    • The product should not be applied to such surfaces, which are exposed to risk of freezing within the next 24 hours, which are frozen or the frost of which is thawing.
    • Due care should be given to prevent the exposure of the material to direct sunlight in hot weather conditions.
    • The product should not be applied on extremely windy weather conditions or on hot surfaces, which are exposed to direct sunlight; and in the cases, where application is imperative under such conditions, the environment and the surface should be prepared for application in advance.
    • The product should not be applied in rainy weather conditions, and the application surface should be preserved from rain for a period of 24 hours.
    • Refer to our technical support hotline for recommendation on different surface applications. (PHONE: 444 4 595)

    Surface and Ambient Temperature
    The surface and ambient temperature should be between +5°C and +35°C whilst at application.
