Number two is all mediumand number 1 is all fine. The fineness modulus, friable particles, light constituents, organic impurities, material soundness, and sieve analysis of the aggregate shall be tested to meet the requirements prescribed. His formula is 7 bags of varied grits of sand, that is one bag each of 1, 2, etc. Have you ever wondered why the word “pound” is abbreviated lb.

The varied grits, ast, different particle size adds increased strength and crack resistance to stucco.
