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
