  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 surface defects, which are deeper than 1 cm, should be repaired with MegaTamir İ or MegaTamir K 24 hours in advance. In the cases, where structural repair mortar should be used; MegaTamir İ Yapısal or MegaTamir K Yapısal should be preferred.
  • Such spaces as horizontal and vertical joints, which are exposed to cracking risks, should be beveled with MegaTamir İ Yapısal or MegaTamir K Yapısal.
  • The drilling cores or mold joints on the surface, if any, should be filled with Megaİzo PU Mastik HM.

  Application Methods :
  • MegaFilm İzo should be applied with a brush, roller or be sprayed. The product may be applied in single coat or double coats, depending on the water absorption of the surface. The application of the product should be followed by the application of Megaİzo K or Megaİzo 2K application subsequent to drying.

  Application Recommendations :
  • Any subsequent material should not be applied on MegaFilm İzo coat before it is completely cured.
  • The product should, once mixed, be used before the expiration of its pot life. Any mortar, the pot life of which has expired, should not be used during the application.
  • Any such foreign substance as lime, cement or plaster should not be added to the mortar prepared.
  • Any extra water should not be added to the mixture.
  • 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 taken to ensure that the material is not exposed to direct sunlight in hot weather conditions, and the product should be mixed with cold water.
  • 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.
