[MW:3328] Re: Painting

Dear Sarvanan,

There is very remote chance of point 1 to occur. The 2nd point is most appropriate one.

Before making any decisionfor rework, I would suggest to just spray the water and wait for 24 Hrs. If there is no sign of rust spots and all other test results are stisfactory (Adhesion, DFT, Profile of Blast surface, etc) No need to go for any rework. Furhter you can check with Paint supplier technical Rep to be sure about your decision.

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,

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.
