Megaİzo Kristalize

Megaİzo Kristalize Cement Based, Crystallized Waterproofing Mortar Resistant To Negative And Positive Water Pressure PRODUCT DESCRIPTION Cement based single component waterproofing mortar, which is resistant to positive and negative water pressure and which penetrates into capillary gaps for waterproofing purposes. AREAS OF USE Megaİzo Kristalize is used for negative and positive waterproofing of sound concrete surfaces in independent swimming pools, sewage and waste water treatment plants, basements, water tanks, elevator shafts, warehouses and parking garages. It is suitable for use on horizontal and vertical surfaces of indoors and outdoors spaces. PRODUCT ADVANTAGES • Fit for contact with drinking water. • Provides the surface with resistance to both negative and positive water pressure. • Easily settles into capillary cracks, fills such cracks, forming a crystal structure, and so ensures waterproofing. 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 Waterproofing No penetration, ≤ 20 gr increase in mass (≥ 5 bars) TS EN 14891 : 2012 (positive; negative) 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 Certificate for suitability for contact with drinking water issued by Water Quality Center, UK according to BS 6920: 2000 (Report Reference No: M 105590) - (24.01.2014) 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 • 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. • Such surfaces as concrete and cement based plaster should be moisturized carefully 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 Kristalize is applied on the moisturized surface with a brush, which should be over saturated with water, in double coat. Once the primary coat thoroughly dries, the secondary coat should be applied as perpendicularly to the primary coat. • Following the application, the product should be moisturized for 5 days in order for the product to penetrate into the surface. • 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 surface should, subsequently to Megaİzo Kristalize application, be protected from external weather conditions and thermal impacts with a plastic cover. • The material applied should be moisturized and protected from exposure to direct sunlight and such factors as frost for 5 days following the application. • Megaİzo Kristalize should, once prepared, 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. • Due care should be taken to ensure that the material is not exposed to direct sunlight in hot weather conditions, 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 the application of subsequent coat 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 30 - 32 % of the product. (7.5 - 8.0 liters of water for a 25 kg package) Mixing Equipment • Low speed electrical mixer (400 cycles/min.) 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 30 minutes Minimum 6 hours Minimum 7 days 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: 1.50 ± 0.01 gr/cm 3 Mortar Density: 1.75 ± 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 3.0 - 3.2 kg. The said values may vary, depending on the surface and ambient conditions. 67
