Wecryl surface protection system OS 11b
The Wecryl surface protection system OS 11b is a high-quality and flexible PMMA coating system that has been tested in accordance with DAfStb-RiLi SIB, DIN V 18026 and TR-Instandhaltung. 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
