Does anyone have an NPT rep contact info. I want to see if my Stonescrapes Mini Pebbles was installed incorrectly. Had tropics blue installed. Except the one guy who acid washed the pool after the 24 hours passed of the pool replaster, there is still a lot of visible pool plaster cream throughout the pool. Half the pool looks like my kids rubbed baby blue chalk all over it, while the rest looks like mini pebbles.
