MegaTamir İ Cement Based Repair And Leveling Mortar With Thin Filling PRODUCT DESCRIPTION Cement based, highly adhesive, non-structural smoothing and repair mortar reinforced with special filling materials. AREAS OF USE MegaTamir İ is used as concrete repair mortar on the floors, walls and ceilings of any buildings, indoors and outdoors. It is also used for the repairing of surfaces prior to granite and ceramic applications. PRODUCT ADVANTAGES • Once applied, the product gains high adherence and strength. • Highly resistant to dynamic loads. • Resistant to impacts and vibration. • Resistant to water and frost. • Prepared and applied easily. PERFORMANCE Compressive strength ≥ 15 MPa (R2) TS EN 12190 Bonding through adhesion ≥ 0.8 MPa TS EN 1542 Limited shrinkage / expansion ≥ 0.8 MPa TS EN 12617 - 4 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 - 3 Class: R2 Ministry of Public Works and Settlement Item No. Ministry of Public Works and Settlement Item No.: 04.613/3A QUALITY CERTIFICATES Conformant to TS EN 1504 - 3. CE APPLICATION PROCEDURE Application Surfaces Indoors and Outdoors Floors; - Cement based trowel coating - Concrete (MegaFilm or MegaFilm BB primer applied) Indoors and Outdoors Walls; - Cement based plaster (MegaFilm primer applied) - Concrete (MegaFilm or MegaFilm BB primer applied) Indoors and Outdoors Ceilings; - Cement based plaster - Concrete (MegaFilm or MegaFilm BB primer applied) Surface Preparation • The application surfaces 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. • 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 • MegaTamir İ should be applied in equal thickness on all surfaces to be repaired or smoothed. • The surface should be finished with a moist sponge following the application. • In the cases, where the product is to be applied in two coats; a stand by period of 2 to 3 hours should be allowed between the primary coat and the secondary coat, and the primary coat should be moisturized prior to the secondary coat application. Application Recommendations • The product should, once mixed, 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 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 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 92 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 Application thickness Applicable coat thickness Required stand by period for secondary coat application Opening the traffic 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 22 - 24 % of the product. (5.5 - 6.0 liters of water for a 25 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 2 to 3 minutes following preparation. Application Equipment • Steel trowel • Smoothing trowel • Sponge Equipment Cleaning The equipment used should be cleaned with water following the application before the mortar dries.
