Wecryl Surface Protection System OS 11b (OS F)
The Wecryl surface protection system OS 11b (OS F) is a high-quality and flexible PMMA coating system, which is tested according to the DAfStb guideline "Protection and Repair of Concrete Structures" and according to ZTV-ING - Part 3 - Section 4 "Protection and Repair of Concrete Structures". This makes the coating system (wear-resistant, pre-filled surface protection layer and top seal) ideal as a surface protection layer with increased dynamic crack bridging for surfaces that can be walked on and driven over.
The surface can be designed in a variety of colors and with patterns or markings. The liquid application and the high adhesion to almost all substrates make the system an economical and high-quality solution, especially in the renovation of parking garages.
Application Areas:- Surface protection and sealing of concrete components with cracks and/or separation cracks close to the surface and scheduled mechanical loading
- Passenger and vehicle traffic
- intermediate decks and floor slabs of parking structures
- Bridge caps

Attributes Description
- highly flexible and crack-bridging even at temperatures up to and including -20 °C (crack-bridging class B 3.2)
- tested according to class OS 11b (OS F) according to the guideline for protection and maintenance of concrete structures of the German Committee for Reinforced Concrete (DAfStb), Oct. 2001
- tested according to class OS 11b according to the DAfStb guideline "Maintenance of concrete components", yellow print June 2016
- tested according to ZTV-ING - part 3 - section 4 "Protection and maintenance of concrete components
