Field of application / properties

KOBAU Polyester-Vlies K 30 is intended for the reinforcement of paint systems in case of plaster surface cracks type A.1 according to the classification in the BFS notice no. 19. KOBAU Polyester-Vlies K 30 is preferably used for the reinforcement of hairline and net cracks in silicone resin or mineral paint systems highly permeable to water vapor. KOBAU Polyester-Vlies K 30 also serves for the reinforcement as well as increase of the layer thickness in flexible coating systems. The product is a polyester fleece consisting of continuous filaments that are thermally fixed. KOBAU Polyester-Vlies K 30 is watertight, resistant to chemicals and solvents and adapts itself perfectly around edges and corners.

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 30 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 30 preferably from top to bottom. 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.
Subsequent work is to be performed observing the instructions of the manufacturer in each case.
