Dear Mike:
“
Is that something the sealer is doing or something I am doing?
”
None of the above. It is simply that certain slabs are of a lower grading than others, and those two particular stones can be susceptible to that grittiness.
As long as the stone industry will not clean its act and classify the different stones for what they actually are instead of these illegal general classifications of “marble”, “granite”, etc. and establish precise criteria for a mandatory grading of the different stones, this kind of confusion will always be there.
May I ask you now to please read and e-sign our Statement of Purpose at:

Ciao and good luck,
Mauri
