Question is how much mottling is normal and inherent for a plaster pool? Ours was replastered with white plaster 3 weeks ago and we still have a creamy beige mottling throughout (floors and walls). I'm reading online, and have been told conflicting opinions about how long plaster takes to cure and if mottling is inevitable and normal. Any plaster pool owners out there who can chime in with their experiences? Thanks!
