We noticed as we have been brushing our new build / freshly plastered pool that there are a few fibers sticking through the plaster around the pool. Is this something we need to be concerned about? Our pool builder said that the plaster company usually burns off any fibers prior to finish plaster but we have a handful of them around the pool sticking through the plaster. They are coming in a couple weeks to clip them for us. Should I be concerned about the long term quality and will it shorten the lifespan of the plaster? I tried to search the forum for a similar problem but wasn't able to see any posts about it after looking through a bunch of posts.
