Sorry if I did not explain properly
The first coat is required to provide adhesion for the birdsand ( A bit like 100's & 1000's on your ice cream ) the following coat is to hide the sand colour of the sand plus give additional adhesion. Also the second coat removes some of the " harshness" of the sand which can be quite abrasive if not toned down with the next layer of paint
some use sugar to sprinkle it then melts away leaving craters in the paint
