Fish Eyes

Fish Eyes are a common problem that occurs in the accurate application of coatings.

What visual appearance do fish eyes take?

Fish eyes appear as round, crater-like holes that penetrate to the substrate.

 What probable causes are there for fish eyes? 

• Contaminants that prevent coating from wetting out the surface (such as grease from fingerprints or oil in the compressed air) 

What suggested solutions can solve the problem? 

• Review the handling, cleaning and surface preparation procedures to assure surface is free from contamination prior to coating
• Check for possibility of silicone contamination
• Install/check efficiency of oil/water trap

Support programs, free testing facilities and application advice are often made available from coating manufacturers, helping prevent problems early in the process, saving time and money.
