Parking garages and trafficked areas have especially high requirements on coatings. The KÖSTER OS 8 System is a highly resistant, easy to apply solution.
Surface preparation is critical and should result in a clean, dry surface free of all bond-inhibiting materials. KÖSTER CT 121 mixed with Quartz Sand 0.06 - 0.36 mm (1:1) is used as a primer and applied with a standard trowel. Immediately afterwards, the primed surface is broadcasted with Quartz Sand 0.4 - 0.8 mm. Through the broadcast with quartz sand, the mechanical resistance is increased and a higher slip resistance is achieved.
After excess Quartz Sand has been removed, the top coat consisting of the solvent-free KÖSTER CT 221 is applied. The KÖSTER OS 8 system has been tested according to the DIN EN 1504-2 guideline and fulfills the supplementary standard DIN V 18026.
Always adhere to the specifications in the respective Technical Guidelines.
