REFERENCE STANDARDS Certifications/Standards TS EN 998 - 2 Ministry of Public Works and Settlement Item No. Ministry of Public Works and Settlement Item No.: 04.478 QUALITY CERTIFICATES TSE CE APPLICATION PROCEDURE Application Surfaces Indoors and Outdoors; - Gas concrete - Brick 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 surface should be checked and be leveled and smoothed in the event of any defects prior to masonry with construction elements such as gas concrete and brick. Application Methods • The MegaBlok mortar prepared should be spread properly and homogenously in equal thickness on the application surface with a trowel. The mortar should, then, be dredged with a 10x10 mm dredge to ensure uniform thickness in application. • During the masonry, the horizontal and vertical joint gaps should be allowed as 3 mm, and due care must be taken to ensure that the joint gaps are thoroughly filled with MegaBlok mortar. Application Recommendations • The product should, once mixed, be used before the expiration of its pot life. Any mortar, 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 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 Smoothing time Workability time The foregoing values represent the results of the laboratory tests conducted at 23 ± 2°C temperature and 50% ± 5 relative humidity conditions.
