A new type of polyamide cover is woven using the infinite fiber method, which minimizes the possibility of fiber shedding. It has an open structure (the fiber bundles are 2/3 unraveled) and a special surface treatment. It absorbs paint excellently and releases it easily and evenly. The lateral overhang of the cover allows painting in corners. Very long lifespan. For painting work with all types of paints, especially those with higher viscosity.
