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.
Usage Areas
MegaFilm BB A204 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.

ConcreteSurface 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 T101 or MegaTamir K T102 6 – 8 hours in advance. In the cases, where structural repair mortar should be used; MegaTamir İ Yapısal T103 or MegaTamir K Yapısal T104 should be preferred.Application Methods :
• Prior to the application, the product should be diluted with clean water weighing 1/3 of the primer and application should be made homogenously on the surface with brush or roll.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.
