What is WFT in painting?

Author: Prof. Lilyan Cole Sr.  |  Last update: Monday, September 29, 2025

Wet film thickness (WFT) is the measurement of the thickness of an applied paint or coating before it dries. Wet Film thickness is measured using a Wet Film Thickness Gauge. Wet Film Thickness Gauges provide an inexpensive, quick and easy method to measure the thickness of coatings immediately after application.

How do you calculate WFT?

WFT = 100 x DFT / VS (WFT = 100 x 90 / 60) therefore giving us 150 microns as the Wet Film Thickness (WFT).

How does WFT work?

Wet film thickness, or WFT is the measured thickness of any applied wet paint that is liquid-based. A wet film thickness gage should be used by the applicator as the coating is being applied to ensure that the measurement is representative of the calculated wet film before significant solvent evaporation occurs.

What is the WFT process?

wft that is an outline of all the mandatory objects you need to build a workflow process and then displays a Process window for you to diagram your process. Once you initiate the Quick Start Wizard, you can take the bottom-up or top-down approach to complete your workflow process definition.

What is the difference between DFT and WFT?

Dry film thickness, or DFT is a measurement of the dry and cured material after all liquid has evaporated. DFT = WFT x % volume solids. For a 67% volume solids material with a WFT of 18 mils, DFT = 18 x 0.67 = 12 DFT. By simply reversing the equation DFT can also be measured to determine what the applied WFT was.

What is the meaning of WFT in paint?

Wet film thickness (WFT) is the measurement of the thickness of an applied paint or coating before it dries. Wet Film thickness is measured using a Wet Film Thickness Gauge. Wet Film Thickness Gauges provide an inexpensive, quick and easy method to measure the thickness of coatings immediately after application.

What is DFT in painting?

Dry film thickness (DFT) or coating thickness is arguably the single most important measurement made during the application and inspection of protective coatings. Coatings are designed to perform their intended function when applied within the DFT range as specified by the manufacturer.

How to check wet film thickness of paint?

Hold the wet film comb in position and wait a few seconds until the teeth are wet. Remove the comb from the film. The wet film thickness lies between the biggest value 'coated' or 'wet' tooth and the smallest value 'uncoated' or 'dry' tooth.

How do you know that a paint coating is the required thickness?

A coating thickness gauge is often used at various stages through a project to check paint thickness in existing coatings on a surface to ensure they are suitable to over paint, checking your progress throughout a project to ensure each coat applied is up to standard and finally at the end of a project to check that ...

What does DFT stand for in paint?

Dry film thickness (DFT) is the thickness of a coating as measured above the substrate. This can consist of a single layer or multiple layers. DFT is measured for cured coatings (after the coating dries). The thickness of a coating depends on the application and type of process employed.

What is the formula for paint?

The basic composition of paint includes four ingredients: pigments, solvents, resins, and additives. All manufacturers follow this formula, opting for their own concentrations of each.

How to check solid content of paint?

A simple method that anyone can do to determine volume solids empirically is to apply paint to a steel surface with an application knife and measure the wet film thickness. Then cure the paint and measure the dry film thickness. The percentage of dry to wet represents the percentage of volume solids.

How thick should powder coat be?

Typical Thickness Guidelines

The majority of powder coatings have a thickness ranging from 2.0 to 5.0 mils (50 to 125 microns). This provides a balanced combination of durability and aesthetics suitable for general use applications.

What is the full form of WFT in paint?

The Wet Film Combs are designed for wet film thickness measurements and come in a range of thickness scales.

What is the full form of WFT in work?

Workforce Transformation (WFT) Workforce transformation is a process, driven by improving the way we recruit, retain, deploy, develop and continue to support the healthcare workforce, to meet the growing and changing needs of local populations – ensuring high quality care for the patients of today and the future.

What does WTV mean?

"WTV" is an abbreviation for "whatever," according to Dictionary.com. It is used the same way as its equivalent, to express indifference, distaste or boredom.

What the heck slang?

idiom. used for showing anger or surprise: What the heck are you doing to my car?

What is the name of the WFT gauge?

Wet film thickness gauge designed to quickly & easily measure the thickness of coatings immediately after they have been applied to a substrate. This gauge also known as Comb, MIL gauge, Step gauge & Notched gauge. The gauge incorporates a series of notches cut into their sides much like the teeth on a comb.

How to control paint thickness?

Measuring every coat allows you to adjust the thickness to meet the manufacturer's recommendations. Use the wet film thickness measurement to predict the dry film thickness once the coating has cured. You can do this easily using the wet and dry film thickness formula.
