I'm getting my pool replastered. I intended on going for plain white plaster. The company doing the work is offering to add 35 - 45% blue quartz to the plaster for strength. This would cost an additional $650. My pool is about 27,000 gallons and has 10+ year old whiter plaster that is in pretty bad condition. I'm in the Dallas Fort Worth area.
Has anyone opted to add quartz to plaster? What are the pros and cons?
