I understand that unmodified thin-set mortar is typically 25-35% portland with most of the balance being a fine sand. If I wanted to make my own where could I obtain this fine sand? What is it called and how is it graded?

    Why would you want to make your own? – bib Feb 20 '15 at 3:14

    Agree with bib. I've made plenty of my own batches of concrete and brick mortar but I don't mess around when it comes to thin-set. – Mazura Feb 20 '15 at 3:23
