Q: Can fiber reinforcement be used in a swimming pool deck or will fibers at the surface be a problem for bare feet?

A: Synthetic fibers that show on the surface should not have any harmful effect, because they won't cut or puncture skin. The fine, polypropylene-based fibers can give new surfaces a furry effect, but they usually wear off by foot traffic if they're ignored. As an alternative, you can reduce the protruding fibers by exposing them to a flame. The flame treatment produces the smoothest surface.
