Measuring the thickness of a ceramic coating without buffing and evaporation
Without getting into mathematics it will be hard to measure a real ceramic coating thickness.
Facts: Ceramic coating application usually takes 10-20ml per layer for a medium size car.
That gives us about 1ml per 1 square meter
Some quick facts:
1 cubic cm = 1ml/cc
1 square meter = 10,000 square centimetres
1 cm = 10,000 microns
Divide the 1ml ceramic coating you apply on a square meter, its a 1 square centimetre divided to 10,000 square centimetres
This gives us 0.0001 cm, which is
1 micron thick
What is the real ceramic coating thickness after application?
After understanding that the maximum ceramic coating thickness can be 1 micron, the residue on the applicator, buffing and evaporation will remove about 50% of the ceramic coating you applied, even if it is a very thick material that is 100% solids, you are not left with much.
