Megaİzo PU 15 Polyurethane Based, UV Resistant, Ready To Use, Elastic Waterproofing Material PRODUCT DESCRIPTION Polyurethane based, lasting, UV resistant, elastic and ready to use waterproofing material with high water vapor permeability, which can be applied prior to or as top coating material. AREAS OF USE Megaİzo PU 15 is used for waterproofing purposes and the preservation of polyurethane foam insulation in such wet spaces as bathrooms, kitchens and balconies, such surfaces that are constantly in contact with water, concrete sheer surfaces, on tops of parking garages, roofs, green roofing systems, swimming pools, flower beds and seeding beds, water storage and distribution canals, such concrete structures as bridges and tunnels and metal surfaces. It is suitable for use on horizontal and vertical surfaces of indoors and outdoors spaces. PRODUCT ADVANTAGES • 900 % elastic. • ANTIROOT certified for resistance to plant roots. • Poses high crack bridging capability. • Fit for light pedestrian traffic • UV resistant. • Water vapor permeability. • Preserves its mechanical properties within the temperature range between -30°C and +90°C. • Repaired rapidly and easily, locally. • Provides high strength against acidic and alkali solutions (10 %), detergents, seawater and oils. • Ensures seamless waterproofing for application surfaces. • Highly adhesive. • A ready-to-use product which is applied easily and rapidly.

REFERENCE STANDARDS Certifications/Standards ANTIROOT APPLICATION PROCEDURE Application Surfaces Indoors and Outdoors Walls; - Cement based plaster (MegaFilm İzo PU primer applied) - Concrete (MegaFilm İzo PU or MegaFilm İzo Epo primer applied) - Ceramic (MegaFilm İzo Epo primer applied) - Glass (MegaFilm İzo Epo primer applied) - Aluminum (MegaFilm İzo Epo primer applied) - Steel (MegaFilm İzo Epo primer applied) - Bituminous Felt (MegaFilm İzo Epo primer applied) - Metal (MegaFilm İzo Epo primer applied) Indoors and Outdoors Floors; - Cement based trowel coating (MegaFilm İzo PU primer applied) - Concrete (MegaFilm İzo PU or MegaFilm İzo Epo primer applied) - Ceramic (MegaFilm İzo Epo primer applied) - Glass (MegaFilm İzo Epo primer applied) - Aluminum (MegaFilm İzo Epo primer applied) - Steel (MegaFilm İzo Epo primer applied) - Bituminous Felt (MegaFilm İzo Epo primer applied) - Metal (MegaFilm İzo Epo primer applied) 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 Megaİzo PU 15 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 24 hours in advance. In the cases, where structural repair mortar should be used; MegaTamir K Yapısal should be preferred. • Following the surface cleaning, MegaFilm İzo PU, in the case of absorbent surfaces, or MegaFilm İzo 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 İzo PU primer should be let dry for 2 to 3 hours while those coated with MegaFilm İzo Epo should be let dry for 8 to 12 hours. Application Methods • Megaİzo PU 15, which should have been thoroughly stirred prior to the application, should be poured on the surface, 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. • Megaİzo PU 15 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 Megaİzo PU Mastik in order for the maintenance of waterproofing. • In the cases, where beveling is not performed; Megaİzo 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 • In respect of the roofs and terraces, which are to be left uncovered, and are not eligible for wandering, where the product is applied as the top coat; UV resistant aliphatic paint or top coating material with high mechanical strength can be applied at the user's discretion. • In the cases, where ceramic tile coating is applied on the insulation; the surface, to which Megaİzo PU 15 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 application surface should be smoothed adequately to prevent water accumulation. • 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. • Megaİzo PU 15 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. Application Limits Bonding Light use Firm use The foregoing values represent the results of the laboratory tests conducted at 23 ± 2°C temperature and 50% ± 5 relative humidity conditions. The values provided as per the table may vary depending on the surface and ambient conditions.
