Re-using Gritty Mix
Today, in my attempt to persuade a friend to undertake using gritty instead of you-know-what, he asked me this question when I said gritty usually lasts for 3-5 years:
"If roughly 2/3 of it is inorganic, why can't you 're-freshen' it with new fines and use it again? Seems to me that would make more sense than making up all new batches from scratch considering the turface and granite should be reusable. I'm assuming the original fines would have broken down in that time."
Well, I wasn't quite sure how to answer. The mix was "spent?"
Can anybody chime in here? Al?
