STAKO ® Cement based, thick grained lime-free repair mortar containing polymer modified fillings which has been developed in order to correct, fill and repair whole surfaces or a part of surface. APPLICATION AREAS Stako is used for repairing normal or light concrete surfaces, cracks and holes in interior and exterior surfaces; surface corrections aimed to remove size faults; surface corrections before ceramic and tile coating operations; small repair works; filling repairing broken or spilled corner parts. Used safely for filling the spalling and holes occurring in these surfaces up to 10 mm and achieving highly smooth surfaces by correcting size defects. PROPERTIES Stako has been prepared using silica sand with appropriate screen opening and grain size as well as Portland cement produced according to DIN 1164. Maximum grain diameter is 0.5 mm. Suitable to be used at thickness of 1.0-10 mm in one application. Excellent adherence strength. Provides proper smoothing and prevents cracking, shrinkage, sagging and collapses during application. It is recommended to use synthetic emulsion based Filli Boya Lateks and water mixture in order to improve the characteristics of Stako when it is fresh and hardened. (1kg Lateks + 4kg. Water) Fresh Mortar Properties: Low water absorbency value. Easily applicable and makes labor saving. Long applicability period. 75 lt fresh plaster can be applied with 100 kg dry Stako. Fresh plaster density: 1,60 g/cm³ Dry powder density: 1.35 g/cm³ Hardened Mortar Properties: High pressure and bending strength. High strength of adherence. Enhanced elasticity. No blooming or mossiness. Pressure Strength ≥10 N/mm2 Pressure Strength ≥ 1,5 N/mm² Pressure Strength ≥ 1 N/mm² APPLICATION Surfaces where Stako will be applied should be cleaned of its blistered coat, dust and all kinds of dirt. Weak and loose surfaces should be cleared of old surface with mechanical methods. Add 25 kg Stako to approx. 5 lt water in a clean cup and mix it with a low-speed mixer (max 400 rpm) until there are no bubbles. Wait 3-4 minutes after first mixing process and achieve appropriate mixture. Depending on surface absorbency, application thickness and weather conditions, surface can be smoothen again after 3 minutes following the application process. Surface should be definitely moistened before applying Stako. Stako can be applied with a trowel as well as a spray machine appropriate for mortar. WARNING Surfaces should be moisten with spraying method morning and evening for 3 days after application in order to prevent sudden water loss and strength reduction at temperatures above +25℃. Surface should be painted without being exposed to rain after Stako application. Otherwise, after surface exposed to rain gets dry completely, Disboxan 451 + water mixture should be thinned at a ratio of 1/1 and applied and preferred primer and paint should be applied on it. Applications should be carried out between +5°C and +30°C. Applied surfaces should be protected against rain, freezing, pedestrian and vehicle traffic for at least 48 hours. Hand tools used for Stako application can be cleaned with water after application. Gloves should be used during application. Eyes and skin should be washed with plenty of water in case of contact with the product. Seek medical advice as soon as possible in allergic cases. CONSUMPTION Consumption is approx. 1,5 kg/m²for each 1 mm coat thickness. Consumption values stated above are approximate values. Precise consumption will be known after completion of application as differences may occur according to gap structures. STORAGE Can be stored for 6 months in its original package, kept in a cool and dry place by protecting against humidity, freezing and direct sun light. PACKAGING 25 kg Kraft Bag
