Question about screening granite for gritty mix.
I am finally making my first batch of gritty mix after reading about it for quite awhile. I screened the Turface using window screen and I then screened the Gran-I-Grit "Growers" size thru 1/8" screen. A large portion of the granite went thru the 1/8" screening and now I am wondering if I should have also screened it using the window screen instead of the 1/8" screen. I have searched a lot of threads looking for the answer but so far have not been able to find this issue addressed.
Thanks - Connie
