We are talking with a pool builder who will most likely be building our pool soon. He uses Wet Edge finishes and my husband and I are trying to figure out the best one to select. We have three small kids and are sensitive to the roughness on their feet. Based on that, we have narrowed it down to Prism Matrix, Satin Matrix, or Primera Stone. I have searched the Wet Edge website as well as this forum but still don't have a good feel for the differences. Would love input from those who have been there!
