Opacity Measurement
Essential sales criteria for architectural paint are hiding power and yield. In other words:
---How many layers are necessary for complete coverage?
---And how many cans will be needed?
Opacity(%) =Y blackx100(%) /Y white
100% opacity means complete hiding, no difference can be seen between the drawdown over black and white.
