Dry Film Thickness Calc

Spraying a coating spec and need to know your target wet film to hit the required DFT? Dry Film Thickness Calc converts wet film thickness to dry film thickness using volume solids — and tells you exactly how much paint you need for the job.

Enter wet film thickness, volume solids percentage, surface area, number of coats, and transfer efficiency. Get DFT in both mil and micron, spread rate, total paint required, and coverage per coat.

DRY FILM THICKNESS:
- WFT to DFT conversion using volume solids
- Results in both mil and micron
- Supports mil or micron input units

PAINT USAGE:
- Spread rate (sq ft per gallon)
- Total gallons needed for the job
- Coverage per coat calculation
- Multi-coat support (1 to 5 coats)

TRANSFER EFFICIENCY:
- Adjustable transfer efficiency percentage
- Accounts for overspray loss in airless, HVLP, and conventional spray
- Shows actual paint consumption vs theoretical

INPUTS:
- Wet film thickness (mil or micron)
- Volume solids (%)
- Surface area (sq ft)
- Number of coats
- Transfer efficiency (%)
