MegaSıva Elyaflı Cement Based, Manually Applicable Fine Plaster With Fiber Additive PRODUCT DESCRIPTION Cement based pre-final coat surface preparation plaster with enhanced adherence, applied manually, which has been reinforced with various chemical additives in order for enhanced resistance to contraction and shrinkage. AREAS OF USE MegaSıva Elyaflı is applied in indoors and outdoors spaces on prime coated gas concrete and prime coated concrete surface and ceilings and on any roughcast (MegaSıva K, MegaSıva Makine İç, MegaSıva Makine Dıº, MegaSıva Elyaflı K) applied surfaces. PRODUCT ADVANTAGES • Resistant to outdoor conditions. • Ensuring high bonding to the surface, the product does not cause spalling and poses high bonding strength. • Being a high performance product, it does not cause contraction thanks to the fiber additive content. • Prepared and applied easily.

REFERENCE STANDARDS Certifications/Standards TS EN 998 - 1 (GP) Ministry of Public Works and Settlement Item No. Ministry of Public Works and Settlement Item No.: 04.476/D QUALITY CERTIFICATES Conformant to TS EN 998 - 1. CE APPLICATION PROCEDURE Application Surfaces Indoors and Outdoors Walls; - Gas concrete (MegaFilm primer applied) - Concrete (MegaFilm or MegaFilm BB primer applied) - Roughcast applied surfaces Ceilings; - Roughcast applied surfaces 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. • The application surfaces should be moisturized with water, where necessary. • 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. • Gas concrete surfaces should, prior to the application of the product, be applied MegaFilm primer and the water absorption of the surfaces should so be reduced. • 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 • The product should be applied with a steel trowel, whereupon the surface should be smoothed with a floating rule. • The application thickness should ranger between 2 mm and 7 mm. • Once plaster dewaters and is sufficiently hardened following the application, the surface should be processed with a trowel and final finishing touches should be made with a moist sponge. Application Recommendations • The surface should be moisturized intermittently for a period 7 days following the application in order to enhance the endurance of the plaster. • Plaster profiles should be employed on the corners in order to ensure a better quality result and high level of efficiency. • The product should not be applied to such surfaces, to which paint, premixed colorful plaster, base coat plaster or exterior coating, and to gypsum surfaces. • 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 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 Plaster surface smoothing time Through dry time 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. (7.5 - 8.5 liters of water for a 35 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 3 to 4 minutes following preparation. Application Equipment • Steel trowel • Smoothing trowel Equipment Cleaning The equipment used should be cleaned with water following the application before the mortar dries.
