GERMA-TECH COATING THICKNESS GUIDE

 

​

WHAT IS THE RECOMMENDED MAXIMUM COATING THICKNESS 

 

300 MICRONS

 

Germa-Tech recommends that when a paint finish reaches a dry film thickness of 300 microns and above, it should either be removed completely, or sanded back to an allowable tolerance which when refinished will not exceed the allowable limit of 300 micron.

 

WHY IS 300 MICRONS THE ALLOWABLE LIMIT

​

Excessive paint film thickness can cause durability problems such as:

• Cracking

• Excessive stone chipping

• Loss of gloss

• Sinkage

• Pickling

• Delamination

 

WHAT IS A MICRON AND HOW TO I MEASURE 

 

Dry film build measures the coating thickness of the cured total paint layer and is measured in microns (µm) or in mil.

 

A Micron is one thousandth of a Millimetre 

 

Various equipment manufacturers produce paint film thickness gauges, of varying quality and cost. These gauges are very simple and easy to use.

 

As part of the initial inspection of a vehicle, prior to paint repair, it should be standard practice to check the paint film thickness and on completion of the repair the final thickness should again be recorded and detailed on a job card.

COATING GUIDE 

OEM - Original Equipment Manufacturer’s paint finish, is typically 90-10 micron. The thickness of a strand of human hair is ~150 Microns.
