MegaFilm BB High

MegaFilm BB High Performance Exposed Concrete Primer PRODUCT DESCRIPTION Polymer emulsion based exposed concrete primer with filling, which does not contain solvent and is used as binder for the purpose of application of cement and plaster based mortars on such surfaces as exposed concrete, wall and ceiling. AREAS USE MegaFilm BB is used as binder for the preparation of such surfaces as exposed concrete and trowel coating for pre mortar application and under the cement based mortars on concrete surfaces with satin plaster. It is suitable for use on indoors and outdoors horizontal and vertical surfaces and on ceilings. PRODUCT ADVANTAGES • Ensures a binder rough surface for exposed concrete surfaces. • Prevents the dusting on the surface. • Enhances the surface adherence of the material to be applied subsequently. • Prevents the water loss of the material to be applied subsequently, and ensures longer workable life. • Applied easily and rapidly. • Free from solvents and environmentally friendly. REFERENCE STANDARDS Certifications/Standards TSE K 208 Ministry of Public Works and Settlement Item No. Ministry of Public Works and Settlement Item No.: 04.613/1i QUALITY CERTIFICATES Conformant to TSE K 208. CE APPLICATION PROCEDURE Application Surfaces Indoors Walls; - Cement based plaster - Exposed concrete - Concrete - Betopan - Plasterboard Indoors and Outdoors Floors; - Cement based trowel coating - Exposed concrete - Concrete Outdoors Walls; - Cemen based plaster - Exposed concrete - Concrete - Betopan 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 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 should be preferred. Application Methods • MegaFilm BB should be shaken prior to application, and be, then, applied to the surface homogenously with a brush or a roller. Application Recommendations • The product should be kept homogenous by, where necessary, stirring it intermittently during the application. • 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 product 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 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 12 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 +35°C whilst at application.

MegaFilm İzo Bitumen Emulsion Based, Surface Preparatory Primer PRODUCT DESCRIPTION Bitumen emulsion based, single compound, solvent free surface preparatory primer. AREAS OF USE MegaFilm İzo is used as primer under the bitumen based waterproofing materials for concrete surfaces, for the insulation of such underground spaces as foundations, cellars, basements and closed parking garages, and for such wet spaces as bathrooms, kitchens and balconies. It is suitable for use on indoors and outdoors horizontal and vertical surfaces. PRODUCT ADVANTAGES • Enables bitumen based waterproofing materials to adhere to the surface more robustly and void free. • Applicable on dry surfaces or on slightly moist surfaces, which are not wet. • Prepared and applied easily. • Free from solvents, and environmentally friendly. REFERENCE STANDARDS Ministry of Public Works and Settlement Item No. Ministry of Public Works and Settlement Item No.: 04.611 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. • The surface defects, which are deeper than 1 cm, should be repaired with MegaTamir İ or MegaTamir K 24 hours in advance.
