Field of application / properties

KOBAU Polyester-Vlies K 50 is intended for the reinforcement of paint systems in case of cracks in way of horizontal and end butt joints (crack type B.1) as well as cracks due to the deformation of different wall materials (crack type B.2) according to the classification in the BFS notice no. 19. KOBAU Polyester-Vlies K 50 is preferably used for the reinforcement of mineral paint systems that are highly permeable to water vapour. KOBAU Polyester-Vlies K 50 is also used for reinforcing as well as increasing the layer thickness of flexible coating systems. KOBAU Polyester-Vlies K 50 is a polyester spun fleece of continuous filaments that are thermally fixed. It is waterproof and weatherproof, resistant to chemicals and solvents.

For use inside and outside.
Processing

Prepare the substrate to be reinforced according to the national regulations and/or BFS notices. Subsequently, apply embedding material uniformly until saturation using a roller or spray gun. Embed KOBAU Polyester-Vlies K 50 from the roll or as a ready-cut in the wet paint avoiding wrinkle formation and bubbles. The webs should overlap in a width of approx. 5 cm. In case of complete reinforcement, roll KOBAU Polyester-Vlies K 50 preferably from top to bottom. In order to achieve smooth surfaces, smoothen by means of a rubber blade. Smoothen the overlapping area to fleece thickness. Thus, surface compensation is ensured by the new coat applied. After complete drying, apply the intermediate and finishing paint coat in the system.
Subsequent work is to be performed observing the instructions of the manufacturer in each case.
