[MW:3325] Re: Painting

Dear saravanan,
To my knowledge I could visualize two problems based on similar past experience.
1. see the painting environment. was there any chance of mud or contaminants mixup.
2. thinner mixed may not be of appropriate proportion as per the data sheet.
Thanks and Regards,
K.Rajagopal

Dear Guys!!!!!!!
 
The project which I am involved following the paint systems as per client spec follows:-
 
Inorganic Zinc(75-100 micron) as a primer
High Build Epoxy(100-150 micron) as a Intermediate
High Solid Aliphatic Polyurethane(40-100 micron) as a finish
 
Total Dft between (215-350 micron)
 
After the complete curing of the finish coat visually I observed tiny pinholes like appearance or fish eye only inspector eye can find them.
 
Please give me the suggestion where the problem from? this appear in almost all the painted works which applied many different days, different paint batch followed by airlesspray method.
