Hi all. So I need to calculate the approximate liters of paint needed to paint 500 pieces about 0.85m2 (580mm by 730mm rectangular pieces, 2 sided) each. The specifications allow thickness of 50 microns. Also I'd like to add 30% over-spray just in case. How do I calculate the amount of paint needed? I am not very good at math. But I did think it might be something along the lines of (number of pieces) * (area) * (thickness) then 1liter / result. So basically 500*.85m^2*(50*0.001) = 21.25 followed buy 0.1m^3/21.25 But this gives me something so small I just don't understand which probably means it must be way off base.
