MegaFilm Multipurpose Surface Preparatory Primer 122 PRODUCT DESCRIPTION Polymer emulsion based, ready to use primer, which stabilizes the water absorbance of concrete and plaster surfaces prior to application, and enhances the adherence by ensuring the dusting that may have emerged on the surface to be retained on the surface, and which does not contain solvents. AREAS OF USE MegaFilm is used for the reduction of the water absorption and the preparation for application of such surfaces as concrete, gas concrete, briquette, plaster, trowel coating, wood and mortar or in advance of the application of coating materials, ceramic adhesives, waterproofing products, leveling trowel coating and self spreading trowel coating application. It is suitable for use on indoors and outdoors horizontal and vertical surfaces. PRODUCT ADVANTAGES • Gives excellent results for the surfaces that require high adherence. • Prevents dusting, penetrating to the surface, thanks to its impregnating nature. • Reduces surface absorption and renders the surface ready for application. • Contributes to the formation of a dust free surface. • A ready to use product which is 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.: 04.466/3 QUALITY CERTIFICATES Conformant to TSE K 208. CE APPLICATION PROCEDURE Application Surfaces Indoors and Outdoors Walls; - Cement based plaster - Gas concrete - Briquette - Concrete - Betopan - Plasterboard - Wooden 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. In the cases, where structural repair mortar should be used; MegaTamir İ Yapısal or MegaTamir K Yapısal should be preferred. Application Methods • MegaFilm 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. • MegaFilm is a ready to use product. Any foreign material should not be added into the product during the application. • The product should not be diluted into the water was added. • 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. • 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.
