Area: sq ft.
Loss Factor: this is the difference between theoretical and actual yield. We at CPI feel that 25-35% is a conservative yet realistic number. This is caused by by many factors such as overspray, expected waste, skin formation of the foam, ambient temperature, thermo shock on cool substrates, etc. As an example, people will see as much as 10 to 15% difference jusr due to ambient differences when the substrate is 40 degrees or 90 degreees.
