We are having pebblesheen blue surf in our pool build, the builder asked me how much shimmer I wanted in my pool. I said a medium effect, so he quoted us 875.00$ for 6 bags, he said " 1 bag per batch. Your pool will be about 6 batches" our pool builder is a small outfit and he is always way behind, very Texan type of man. Anyway, does this seem to too much abalone shell? I read many people say - I added one or two bags - ,although my builder could have small bags which could really only mean 2 bags, I am so sick and tired of this build that I just want it over (we are building a house too so it's been overwhelming) So I assume the plaster company is adding bags to each batch of plaster/pebbesheen, which means it's not hand spread, will be on the walls etc. Can anyone assist me making a decision on this.. Thank you mucho.
