Megaİzo Lastik 5

Megaİzo Lastik 5 Elastomeric Polymer Based, Ready To Use, Elastic Waterproofing Material PRODUCT DESCRIPTION Elastomeric polymer based, ready to use, elastic water proofing material, which can be applied prior to the top coating material in indoors spaces. AREAS OF USE Megaİzo Lastik 5 is used as waterproofing material in such wet spaces as bathrooms and kitchens and inclined roofs coated with concrete, plaster and cement. It is suitable for use on horizontal and vertical surfaces of indoors and outdoors spaces. PRODUCT ADVANTAGES • Does not cause contraction. • Highly adhesive. • Ensures seamless waterproofing for application surfaces. • Elastic. • A ready to use product, and is applied easily and rapidly. • Not contain solvents and is environmentally friendly. PERFORMANCE TYPE: DM Dispersion based, waterproofing product applied in liquid form. Initial adhesion strength ≥ 0.5 N/mm 2 TS EN 14891 : 2012 Adhesion strength after water contact ≥ 0.5 N/mm 2 TS EN 14891 : 2012 Adhesion strength after thermal ageing ≥ 0.5 N/mm 2 TS EN 14891 : 2012 Adhesion strength after freezing – thawing cycles ≥ 0.5 N/mm 2 TS EN 14891 : 2012 Adhesion strength after hard water contact ≥ 0.5 N/mm 2 TS EN 14891 : 2012 Waterproofing No penetration, ≤ 20 gr increase in mass TS EN 14891 : 2012 Crack bridging capability under standard conditions ≥ 0.75 mm TS EN 14891 : 2012 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. REFERENCE STANDARDS Certifications/Standards TS EN 14891 TS EN 1504 - 2 Ministry of Public Works and Settlement Item No. Ministry of Public Works and Settlement Item No.: 04.509 QUALITY CERTIFICATES Conformant to TS EN 14891 and TS EN 1504 - 2. CE APPLICATION PROCEDURE Application Surfaces Indoors Walls; - Cement based plaster (MegaFilm primer applied) - Concrete (MegaFilm or MegaFilm BB primer applied) Indoors Floors; - Cement based trowel coating (MegaFilm primer applied) - Concrete (MegaFilm or MegaFilm BB primer applied) Surface Preparation • Application surfaces should be sound, clean, dust free, and free from molding oils and other foreign substances. Such materials as mortar and cement residues should be peeled off. • Edge and corner joints should be beveled with MegaTamir İ and MegaTamir K repair mortars in the cases where waterproofing tape is not used. In the cases, where structural repair mortar should be used; MegaTamir İ, MegaTamir İ Yapısal or MegaTamir K Yapısal should be preferred. • Upon the completion of the surface cleaning, MegaFilm primer should be applied in a single coat with a brush and be left to dry for 1 to 2 hours in order to enhance the bonding strength and stabilize the surface absorption. • Exposed concrete surfaces should be applied MegaFilm BB exposed concrete primer in single coat and be left to dry for minimum 3 hours prior to the application of the adhesive mortar in order to enhance the adhesion strength. Application Methods • Megaİzo Lastik 5, being a ready to use product, should be applied on the surface in double coat with a brush or a roller. Once the primary coat thoroughly dries, the secondary coat should be applied as perpendicularly to the primary coat. • Edge and corner joints should be beveled with MegaTamir İ and MegaTamir K repair mortars 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 may be applied after the placement of Megaİzo File 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 • 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. • Megaİzo Lastik 5 is ready to use. Any foreign material should not be added into the 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 +30°C whilst at application. Application Limits Useful time for product - Pot life Stand by period between coats Required standby time before subsequent application 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 Megaİzo Lastik 5 is a ready to use product. Mixing Equipment Megaİzo Lastik 5 is a ready to use product. Mixing Period Megaİzo Lastik 5 is a ready to use product. Application Equipment • Brush • Roller Equipment Cleaning The equipment used should be cleaned with water following the application before the product dries. TECHNICAL PROPERTIES Chemical Structure: Elastomeric polymer based waterproofing mortar Density: 1.50 ± 0.01 gr/cm 3 pH: 8 - 9 Color: Yellow Maximum 3 hours Minimum 6 hours Minimum 3 days CONSUMPTION Recommended consumption amount for double coat application (in roughly 2 mm thickness) on 1 m 2 surface is 1.0 kg. The said values may vary, depending on the surface and ambient conditions. 63
