Re: [MW:7863] Surface preparation and coating

Dear Sundaram,

 

The required profile is obtained to the project either through

• Manufacturers data sheet
• Client Specification

Depending on the requirement we will be choosing the grit size.Normally qualification test will be there, and if the grit size is correct I think there will not be much problem.Profile above the limits may affect, if the primer coat is of low DFT. Other wise the effect is more consumption of paint.

 

 

Regards,
 

Arun S Das
