Recently I had ordered some 5/4 and 4/4 HardiTrim cement fiber board trim. It arrived and my crew painted it (I typically paint it first, install it, then paint it again). Anyway, my trim carpenter was getting frustrated because there were three (not just two) thicknesses of trim in the pile (see PIC), each an 1/8 inch apart in thickness.
It took me all morning to figure out what was going on. Anyone want to guess how this error occurred?
