Megaİzo PU 6 Bitumen Modified, Double Component, Super Elastic Waterproofing Material PRODUCT DESCRIPTION Bitumen modified, rapidly curing, permanently elastic polyurethane waterproofing material, which can be applied prior to the finishing coating material, and is applied for lasting waterproofing of foundation and retaining walls of buildings. AREAS OF USE Megaİzo PU 6 is suitable for use in the foundations and retaining walls of buildings, in concrete structures, below ceramic tile coatings in bathrooms, terraces and roofs, in asphalt and bitumen sheets, EPDM membranes etc. and also as joint filling for the gaps of horizontal and vertical joints and control joints. It is suitable for use on horizontal and vertical surfaces of indoors and outdoors spaces. PRODUCT ADVANTAGES • 2400 % elastic. • Resistant to water and frost. • Intercepts water vapor. • Poses high crack bridging capability. • 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 (5 %), detergents, seawater and oils. • Ensures seamless waterproofing for application surfaces. • Highly adhesive. • Prepared and applied easily. PERFORMANCE Expansion at breaking point >2400 % ASTM D 412/ DIN 52455 Tensile strength >2 N/mm 2 ASTM D 412/ DIN 52455 Water pressure resistance Leak-free (1 m water column, 24 hours) DIN EN 1928 Adhesion to concrete surface >2.0 N/mm 2 ASTM D 903 Hardness (shore A hardness) 35 - 40 ASTM D 2240 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. 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) Indoors and Outdoors Floors; - Cement based trowel coating (MegaFilm İzo PU primer applied) - Concrete (MegaFilm İzo PU or 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 7 % at maximum. • The fresh concrete surface should be let dry for minimum 28 days before application. • The surface, on which Megaİzo PU 6 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 6, 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, brush or notched trowel. • Megaİzo PU 6 should be applied in double coat on the surface. • The secondary coat should be applied 12 hours (maximum 24 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 • Immediately following the thorough drying; the application surfaces should, with due consideration of the related details, be covered and protected with thermal insulation panels, drainage panels, geo-textile seal etc., and the application surface should never be left uncovered. • The product should not be applied against negative water pressure. • The product should, once mixed to homogenous consistency, 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. • 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 application. • 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 Useful time for product - Pot life Curing time Opening the light pedestrian traffic 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. APPLICATION INSTRUCTIONS Mixing Ratio Component A (20 l) and component B (20 l) should be thoroughly mixed. Mixing Equipment • Low speed electrical mixer (400 cycles/min.) • Special tip stirring equipment Mixing Period First of all, component A should be stirred for 3 to 5 minutes with a low-speed mixer. Following a settlement period of 15 to 20 seconds, component B should be added to component A and be so mixed and stirred until a homogenous mixture is obtained. Application Equipment • Roller • Brush • Notched trowel 30 - 35 minutes 1 - 3 hours 12 - 24 hours 7 days Equipment Cleaning The equipment used should be cleaned with cellulosic thinner following the application before the product dries.
