Megaİzo Lastik Mono Cement Based, Single Component Waterproofing Material PRODUCT DESCRIPTION Cement based, polymer reinforced, single component waterproofing mortar resistant to positive water pressure. AREAS OF USE Megaİzo Lastik Mono is suitable for use on horizontal and vertical surfaces of indoors and outdoors spaces, on basement walls and on such spaces as water tanks. PRODUCT ADVANTAGES • Provides the surface with positive water pressure resistance. • Highly adhesive. • Poses elasticity and crack bridging capability. PERFORMANCE TYPE: CM, waterproofing material with cement content, applied in liquid form, which, under standard conditions, poses crack bridging capability under standard conditions and at low temperatures. 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 Waterprooding 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 1504 - 2 Ministry of Public Works and Settlement Item No. Ministry of Public Works and Settlement Item No.: 04.477/2 QUALITY CERTIFICATES Conformant to TS EN 1504 - 2. CE APPLICATION PROCEDURE Application Surfaces Indoors and Outdoors Walls; - Cement based plaster - Concrete Indoors and Outdoors Floors; - Cement based trowel coating - Concrete Surface Preparation • Application surfaces should be sound, clean, dust free, and free from molding oils and other foreign substances. • 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 may be preferred. • Such surfaces as concrete and cement based plaster should be moisturized with clean water immediately before the application. The application should be started after the drainage of the surface water and due care must be taken to make sure that the application surface is moist, not wet. Application Methods • Megaİzo Lastik Mono waterproofing mortar is applied with a brush in two coats. • 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. • In the cases, where a subsequent coat application is to be performed 12 hours later or after a longer period of time, the surface should moisturized again prior to application. Application Recommendations • 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. • 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 protected from air currents 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. • The material applied should be protected from exposure to direct sunlight and such factors as frost after the application 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. • 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 prepared mortar - Pot life 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 The product should be mixed with water, weighing equal to 40 % of the product. (8 liters of water for a 20 kg package) Mixing Equipment • Low speed electrical mixer (400 cycles/min.) • Special tip stirring equipment Mixing Period The product should be stirred with a low-speed mixer until any dry dust and globs are eliminated. The mortar should, then, be stirred once again for 1 to 2 minutes after being had settled for 3 to 4 minutes following preparation. Application Equipment • Brush Maximum 45 minutes 4 - 5 hours Equipment Cleaning The equipment used should be cleaned with water following the application before the mortar dries. TECHNICAL PROPERTIES Chemical Structure: Cement based waterproofing mortar, containing water repellant additives Dry Density: 1.20 ± 0.01 gr/cm 3 Mortar Density: 1.65 ± 0.01 gr/cm 3 Grain Size: ≤ 600 µm Color: Gray CONSUMPTION Recommended consumption amount for double coat application (in roughly 2 mm thickness) on 1 m 2 surface is 2.8 - 3.2 kg. The said values may vary, depending on the surface and ambient conditions. 54
