Re: [MW:24226] Painting DFT guage for individual layer reading.

Hi,

You cannot measure the DFT of each under coat layer once top coat is applied. 

Let us consider a surface is painted with three coat paint system, A-Primer, B-Mid-coat & C-Topcoat. So thickness can be measured as follows.

DFT of Coat 'A' - Can be directly measured once it is applied & dried.

DFT of coat 'B' - Actual DFT measured from the surface - DFT of Coat 'A'

DFT of coat 'C' - Actual DFT measured from the surface - (DFT of Coat 'A'+DFT of coat 'B')

Dear WI / PI,s,

 

Please provide details of available Painting Guage to define individual paint layer DFT for multi layer paint system.
