Dry Film / Wet Film Calculator

Quick conversion of a specified dry film thickness into theoretical wet film thickness based on volume solids content and thinner percentage.

This calculator estimates the wet film thickness required to achieve a specified dry film thickness, taking into account the coating volume solids content and any thinner addition.

It is intended for field checks, project preparation, coating applicators, coating inspectors and quality personnel who need a simple reference before or during coating application.

DFT → WFT [Min to Max]

Effective volume solids: 70 %

WFT

Theoretical Minimum Wet Film Thickness
Calculated from the nominal dry film thickness.
Theoretical Maximum Wet Film Thickness
Calculated from the maximum dry film thickness.
Parameter Value Used
Formula without thinner WFT = DFT ÷ (Volume Solids / 100)
Thinner correction WFT = DFT × (1 + thinner / 100) ÷ (Volume Solids / 100)
Rounding Values rounded to the nearest 10 µm
Check the entered values: volume solids must be greater than 0%.
Note: This calculator is a practical calculation aid. Applicable requirements remain those specified in the product data sheet, applicable standards, project specifications, approved procedures and contractual documents.
