Wecryl surface protection system OS 11b
The Wecryl OS 11b surface protection system is a high-quality, flexible PMMA coating system that has been tested and certified in accordance with the Technical Rules for the Maintenance of Concrete Structures (TR Instandhaltung), DAfStb Rili SIB 2001 and DIN EN 1504-2. This makes the coating system, consisting of an elastic surface protection layer (hwO) and crack-bridging top layer, ideal as a surface protection layer with increased chemical resistance and improved cleaning properties for surfaces that can be walked and driven on.
The surface can be designed in a variety of colors and with patterns or markings. The outstanding crack-bridging properties make the system an economical and high-quality solution for the long service life of parking garages.
Application Areas:- Surface protection and sealing of concrete components with near-surface cracks and/or separating cracks and planned mechanical stresses
- Passenger and vehicle traffic
- Intermediate decks and floor slabs of parking structures
For further detailed information, please refer to the installation guidelines.
