Answer»

Right choice is (b) 8 mm

Easiest explanation: In SAND faced finish, the thickness of the FIRST coat is 12 mm while the thickness of the second coat is 8 mm. The sand in the mortar mix for the second coat should be perfectly screened in ORDER to obtain a uniform size resulting in the surface having sand GRAINS of uniform density.
