APPLICATION PROCEDURE<br />
Surface Preparation<br />
• The application surface should be dry, clean, sound and dust free, and should have been<br />
cleansed of oil, dirt or any materials that may prevent adhesion, and any such materials as<br />
mortar and cement residues should be scraped from the application surface.<br />
• The surface defects, which are deeper than 1 cm, should be repaired with MegaTamir İ or<br />
MegaTamir K 24 hours in advance. In the cases, where structural repair mortar should be<br />
used; MegaTamir İ Yapısal or MegaTamir K Yapısal should be preferred.<br />
• The molding oil residues on the concrete surface, if any, should be cleaned with high pressure<br />
water. The surface should, upon drying, be prepared for application with MegaFilm İzo.<br />
Application Methods<br />
• Edge and corner joints should be beveled with MegaTamir İ and MegaTamir K repair<br />
mortars in order for the maintenance of waterproofing.<br />
• The bottom surface of the cover should be molten with blowpipe flame, and should be<br />
adhered to make sure that the margin parts at joints overlap.<br />
• Margin parts should be allowed at the joint points by 10 cm on the width and by 15 cm on<br />
the length.<br />
• The membrane tiers should be formed perpendicularly in the same direction as the slope at<br />
all layers, and tusk tenon should be applied between any two tiers to ensure that the joint<br />
points do not overlap to the furthest extent possible.<br />

Application Recommendations<br />
• Due care must be taken to make sure that the membrane selected is suitable for the<br />
prevailing climate conditions and the physical characteristics of the building.<br />
• Due care must be taken to make sure that all parts are adhered upon the completion of the<br />
application.<br />
• In cold weather conditions, the membrane should be kept in a warm environment prior to<br />
the application, and applied at such temperatures higher than +5°C.<br />
• The products should be applied in single coat or double coats for foundation waterproofing<br />
applications, depending on the ground water content of the soil, the prevailing geographical<br />
conditions of the region and the ground structure.<br />
• In the case of basement tanking application against pressure water, the products are,<br />
generally, recommended to be applied in double coats.<br />
• For roof insulation applications, if the slope is more than 5%, then one-coat of Megaİzo<br />
PK4, Megaİzo PK4 Plus or Megaİzo PK4 Super Plus could be applied according to the<br />
climate conditions and physical properties of the structures.<br />
• The insulation should be sandwiched between steel flanges at crossing spots, where the<br />
insulation is likely to be punctured.<br />
• Due care must be taken to ensure that the insulation material is not damaged by mechanical<br />
impacts in the cases of coating over the insulation.<br />
• The application surfaces should, with due consideration of the related details, be covered<br />
and protected with thermal insulation panels, drainage panels, geo-textile seal etc., and the<br />
application surface should never be left uncovered.<br />
• The product should not be applied on unsound surfaces. The soundness and the load-bearing<br />
capacity of old surfaces should be checked prior to adhesion.<br />
• The surface should be preserved from air currents and water contact during and after the<br />
application.<br />
• The product should not be applied to such surfaces, which are exposed to risk of freezing<br />
within the next 24 hours, which are frozen or the frost of which is thawing.<br />
• Due care should be given to prevent the exposure of the material to direct sunlight in hot<br />
weather conditions.<br />
• The product should not be applied on extremely windy weather conditions or on hot surfaces,<br />
which are exposed to direct sunlight; and in the cases, where application is imperative under<br />
such conditions, the environment and the surface should be prepared for application in<br />
advance.<br />
• The product should not be applied in rainy weather conditions, and the application surface<br />
should be preserved from rain for a period of 24 hours.<br />
• Refer to our technical support hotline for recommendation on different surface applications.<br />
