GLOSSARY TERM
Wet Film Thickness (WFT)
The thickness of a layer of paint or coating when it is still wet, measured in mils or microns.
INFO
What it is
Wet film thickness, or WFT, is the thickness of a coating measured immediately after application while it is still wet, usually checked with a simple comb gauge.
Why it matters
Measuring WFT during application lets the applicator confirm enough material is going on to cure to the correct dry film thickness. It is a real-time check that the coating will perform.
Where it is used on a project
Used during application of protective and architectural coatings, particularly where reaching a specified dry film thickness is important.
How NECC approaches it
We monitor wet film thickness as we apply, so coatings build to the correct depth and cure to the dry film thickness the specification and guarantee require.
