Will I Get 'Hairy' Concrete With Polyvinyl alcohol Fibers?
All lightweight fibers can produce "hairy" concrete. The fibers that float, like polypropylene, suffer this problem to a greater extent. Polyvinyl alcohol has a density of 1.3, so the fibers do not float. However, you must finish the concrete properly or some fibers will be vertically aligned.
