Hello,
I'm trying to apply an epoxy coating resin (bisphenol A epoxy resin) onto mild steel, with a bar coat of 100 micra. The resin to hardener ratio is 2:1.
When the surface begin drying some defects appear as the photo show. The surface preparation was done according to  ASTM- G1- 03, and I tried to repeat the process with a bar coat of 200 micra and the result was the same. 
What is wrong? 
Can you help me?
Many thanks

Thank you very much for your answer. But I have another doubt about the process: How much time should I wait, after introducing the curing agent into the resin, before applying the mix onto the metal substrate? This is not mentioned in the TDS.

I will appreciate any recomendation about this issue.

Best regards
