I am starting the construction of my infinity pool. I am having a Tahoe Blue Quartzscape finish. My PB is going to do an acid bath (fill the pool, add acid and brush the pool for a number of days) versus an acid wash and pressure wash before the pool is filled. I would imagine that I have to let them do it the way they want to or I risk the warranty. Are both methods to expose the aggregate acceptable? Thanks in advance for your feedback.
