MegaSıva Makine Serpme Cement Based Premixed Preliminary Base Coat PRODUCT DESCRIPTION Cement based, machine applied preliminary base coat with filling material in appropriate granulometry, which is used for surface preparation purposes. AREAS OF USE MegaSıva Makine Serpme is used on gas concrete, concrete, briquette, brick and natural rock vertical surfaces and ceilings. The product is applied in indoors and outdoors spaces. PRODUCT ADVANTAGES • Providing high bonding to the surface, the product does not cause spalling and poses high bonding strength. • Ensures convenience in control, preparing the surface as appropriate for the plaster application. • Easily and rapidly applied by machine. PERFORMANCE Bending strength > 2.0 N/mm 2 TS EN 1015 - 11 Compression strength > 6.0 N/mm 2 TS EN 1015 - 11 Dry bulk density 1.65 ± 0.10 gr/cm 3 TS EN 1015 - 10 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. 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 QUALITY CERTIFICATES Conformant to TS EN 998 - 1. APPLICATION PROCEDURE Application Surfaces Indoors and Outdoors Walls; - Gas concrete - Concrete (MegaFilm or MegaFilm BB primer applied) - Briquette - Brick - Vertical surfaces of natural rock Ceilings: - Concrete (MegaFilm or MegaFilm BB primer applied) 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. • 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 secondary coat of plaster should be applied minimum 24 hours after the application of MegaSıva Makine Serpme, after which the surface should be gauged and finished. 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. • The product should not be applied 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. 120 • 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 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 18 - 20 % of the product. (6.0 - 7.0 liters of water for a 35 kg package) Mixing Equipment Premixed plaster mixing and spraying machine Mixing Period The mortar shall be applied with the premixed plaster mixing and spraying machine. Application Equipment Premixed plaster mixing and spraying machine Maximum 30 minutes Equipment Cleaning The equipment used should be cleaned with water following the application before the product dries.
